For firing on armour, use the maximum charge for abta-
'ning ffect shorter time of flight and a
i higher p penetration effect,
more grazing trajectory.
Far demolition of very fortified targets of small dimension? use the appropriate maximum charge.
Use of Table II
The data for each charge are given in Table II separately.
The data contained in that table are given in the general order
of conventional columns.
Column 1 - contains data for the distance to the target
for each 100 meters and column 1 a in yards.
Column 2 - gives data for the range quadrant intervals.
The value of, the interval A X = 50 m correspond to' high
explosive anti-tank shell and is applicable to the third charge of round B0c-357M. For orther propelling charges the number
of the interval is given which corresponds to the respective
range.
The scale in graduations meters is used for firing with
the third propelling charge in the case when Firing Tables are
not available, providing that one interval corresponds to the
change in range for 50 m 2 intervals = 100 m etc.
For other propelling charges 1 2 and 4 data for the
range quadrant in graduations meters are applicable and can
be used only when the Firing Tables are available or abbrid-
ed firing tables are available.

There are no data in this column for high-angle fire, as
the range q b uadrant is graduated for low-angle fire only.
Column 3 - gives data for the range quadrant in mils

Column 4 - contains data for the angle of elevation in
degrees and minutes. Data from this column are used when
firing with the gunner's quadrant in degrees and minutes, eit-
her for high or low-angle fire.
Column 6 - contains data for the ordinate of the sum-
mit vertex of the trajectory in meters for computing of cor-
rections due to wind and for range corrections awing to diffe
rences rences in the air temperature.
Column 7 - contains data for the time of flight in se-
conds. This column is used for distinguishing awn bursts for

computation of the angle of lead for firing on moving targets
and for conducting of planned fire missions.
Column 8 - contains data for the terminal velocity in
mVsec. and is used for computing the energy of the point of

The ballistic wind data are given by the meteo-station.
The range corrections for wind are taken for the ordinate of

component of the wind is obtained from the Table VI after de-
composing the wind into components. In order to compute the
range correction the value shown in the column 21 should be
divided by 10, thus obtaining the value AWx = 1 m,/ sec. and
the result should be multiplied by the number obtained in the
Table VI for the longitudinal component of the wind.
If ballistical wind is not vailable the ground wind for
314 of the ordinate of the summit of the trajectory should be
taken.

If the a temperature is higher than the normal oner the at-

An increase of temperature by 10? reduces the air den-
sity sitY by 45 grams and for a difference in altitude of 180 meters,
the temperature would be reduced by 1?. Inasmuch as the alti-
tude increases the temperature decreases.
The differences in air temperature are given in the metro-
tation for different strata of the atmo-
message of the metea-s
sphere.
In order to compute the range correction due to air tem-

metro message, should be added the difference in altitude of
the meteo-station with its mathematic sign, divided by 10 be-
forehand, or use the Table Xa and Xb.
The barometric pressure uniformly decreases with the
increase of height by appr. 1 mm per each 10 m of altitude, i.e.
the. eater is the altitude, the lesser is the pressure.
If the difference in barometric pressure is negative, the
atmosphere is denser, the projectile will fly farther and the
correction should be deducted and vice-versa.
In order to compute the range correction, it is necessary
to divide the value from this column by 10, thus obtaining

Use of Table VI
The table VI gives data for decomposition of the ballisti-
cal wind into components.
On different altitude the wind has different speed "and
direction. The wind is artificially determined and the sum of
corrections is given as for the actual wind. The wind computed
according to strata of the atmosphere is the ballistical wind
being given by the meteorstation.
The wind is computed according to strata in hundreds of
meters 200 400, 800, 1200, 1600, 2000, 2400 and 4000 being
given in the fourth figure in the metro message, while

The wind affects the direction and range of firing in de-
pendance upon the angle. and speed. The angle of wind is the angle between the direction of firing and the
direction of the

from the firing direction to the direction from which the wind
blows.

Use of Table VIII
This table contains data for conversion of mils in de-
grees and minutes.
The values in degrees and minutes. for mils from 1 to
99 are shown in the right half of the Table and for conversion
,
they y should be added to the values for hundreds of mils from
the left half of the Table.
Use of Table IX
This Table contains data for conversion of degrees in
minutes and mils.
The values in mils for the minutes are shown in the
right half of the Table and for conversion the should be
added to the values of degrees from the left half of the Table.
Use of Table Xa and Xb .
This Table serves for conversion of barometric pressure
.
for the firing
position VF FP), if the pressure of the AMS
(artillery metee-station is known as well as difference in
altitude of the metea-station and firing position.
The Table Xa is used when the firing position is
above
and the Table Xb when it is below the AMS.
Example: The barometric pressure at the AMS is 716 mm. What
is the barometric pressure at the firing position if:
a) VP is above the AMS by 180 m nd
b) VP is below the AMS by 320 m?
a From the Table Xa (by interpolation), the pressure VP .701 m
is determined,
b) From the Table Xb (by interpolation), the pressure VP = 744 m
is determined.
Use of Table XI
This Table
serves for a secure and prompt determina-
tion tion of sign of the deflection and range corrections due to
various factors affecting the flight of the projectile.

5. Abridged preparation of initial elements
Prior to assignment of the firing mission:
- The base piece and observation post are plotted on
the map as well as the initial direction passing
th.rought these
points.
- The altitude of the target is determined on
the map.
After assignment of the firing mission: - The target is plotted on the map board).
- By measuring on the map (board), the deflection of
the initial direction to the target is
determined.
The topographic distance range of
the target is measured
on the map.
- The angle of site of the target is determined according
to the formula:
where:

- Corrections due to difference between actual and table
firing conditions are approximately determined and recorded.
- The initial elements are determined.
- The coefficient of the distance KU and the azimuth
displacement (SU) are determined and by a eat parallax

MD = coefficient by correction - see Drwg. 9).
6. Computation of ordinate of the trajectory
Approximate determination of the ordinate at any point
of the traJ'ectorY ~ , in low - angle fire is made according to the
formula:
Yd = d (E - Td)
irhere:
Yd = ordinate sought; d = horizontal distance for which
the ordinate is sought in km? E- angle of elevation for firing
on the target; Td = elevation table for distance d.

rupted threads of the same length, connecting the barrel
with the mantle.
On the rear/cylindrical part of the barrel there
is a movable ring with its holder screwed into the barrel.
Through this ring the bar is inserted, when disassembling
and assembling the barrel. In addition to the above mont-
ioned function, this ring, entering with its square pro-
jection in a slot on the mantle, prevents the barrel from
rotating in the mantle the very moment the breechring is
being separated from the barrel.
In order to prevent the ring from moving, after
the barrel has been assembled, one half of the ring is
thinner and this part is placed in a slot iii- the front
part of the breechring.
Welded onto the conical part of the barrel is
an arc-shaped adapter with a circular pad on its reinforc-
ed part, fixing the barrel to the pack-saddle.
Welded onto the slightly conical part towards
the front end of the barrel is a movable ring through which
the bar is passed when disassembling and assembling the
barrel.
on the cylindrical front mart of the barrel the-
re are two notches, guiding the barrel through the mantle
in disassembling and assembling the bun. The smaller squa-
re notch moves across the correspondent slot in the upper,
and the bigger one in the lower part of the mantle.
The ballistic life of the barrel is approx.
12ooo rounds, The standard forcing cone is 3o6 ? 4 mm.
Method of gauging, see in section for barrel inspection
during firing.
B. THE BRECHRING

being cylindrical and slightly conical.
On the rear part there is a shackle for putting
a bar through it when disassembling and assembling the

1' BR1 CHBLOCK.. AND THE ..SEMIAUTOMATIC MF CHANISM
C. TH
/Fig.6-19/
The semiautomatic function of the breechblock
is accomplished by the semiautomatic mechanism, whose
action is based upon exploiting the movement of the bar-
rel when returning the barrel in battery.
The firing is done by means of a trigger and
can be done from both sides of the braechring. At station-
ary targets the gun is fired by the assistant gunner, by

Ing the turn of the operating parts shaft.
The semiautomatic mechanism retainer has the
function of. preventing the inner connector from turning,
until the notch on the cover of the circular box gets under
the lock, so lifting the dent of the operating lever hand-
1 e lock.
The retainer of the semiautomatic mechanism con-
sists of the following parts :
- the retainer with two dents, and
- the spring.
Thy; bigger dont on the retainer serves to hold
~;hinner connector of the semiautomatic mechanism. Sliding
over the smaller dent the circular box pross:es the whole
retainer into its recess, thus unlocking the inner connect-
or and opening the breechblock under the action of the
spring.
The slider with the latch are integral parts of
the semiautomatic mechanism and that of the parts designed
for opening the breechblock. It is located on the copying
device which connects the circular box with the cradle. The
slider is an integral part of the operating cam, and the
rocker arm is rocking around its shaft and is provided with
a spring pushing it permanently to the right. The latch is
fixod to the operating cam by means of a ring, a washer and
a cotter pin.

chanism. On the operating cam there are the slider with
the latch, forming part of the semiautomatic mechanism,
and the auxiliary trigger, the latter being an integral
part of the firing parts of the breechblock.
The operating cam is fixed to the cradle. When
removing the operating cam it is necessary
- to separate the breechring from the cradle,
-- to pull back the barrel with the bree chring
and tho mantle for 20 cm,
- to remove the operating cam by pulling it back-
wards.
9 - Semiautomatic action of the breechblock
During the recoil of the gun the opc~rat ing parts
shaft lug by-passes the slider and the latch on the right,
and pushing the latch to the left, slides over the latter.
The parts of the breechblock are, during recoil,
at rest.
During the return-in battery, the operating
parts shaft reaching the latch, strikes it with the lug,
the latch together with the slider resists, pushing the
lever backwards. The lug of the lever slides over the left
side of the latch and the slider, since striking tho latch
and slider the lever turns together with the operating
yI
parts shaft. By the turning of the shaft, the opening and

the bree chbl o ck.
By its to ruing motion the circular box pushes the retainer
with its lug, releasing the inner connector. The very mo-
ment the breechblock opens the extractor arms catch the
breechblock and keep it in its open position.
Simultaneously with the straining of the open-
ing spring the closing spring also strains; its unction
is the same as in manual opening.
If the extractor arms disengage the breechblock,
th, closing spring turns the operating parts shaft. Toge-
thor with the shaft moves also the operating lever, trans-
mitting its motion to the breechblock, thereby closing
th9 barrel.
D. r?IRING
a The gun is always fired by hand; firing can be
done from the left or from the right side of the breech-'
ring. Firing from the left side is performed by the gunner
at moving targets, and with a reduced number of crew, while
firing in all other cases is carried throth by the assis-
tart gunner.
When engaging moving targets, the gunner tracks
targets operating with his left hand the elevation
the ,,
hand wheel, and with his right hand the azimuth hand wheel.
by operating with the right hand the trigger hand-
He fires y
le. The gunner's trigger, through the assistant gunner's
trigr,ershaft, 1 if is the pusher which, by pushing the rol-
ler, lifts the trigger lever, whose shaft turns in its
bearing and catching the trigger lug with the notch,pulls
it downward. As a result of being pulled downwards the
head compresses the spring, and the lug releases the
which is driven forward under the action of
striker rim,

striking the primer.

lanyard.
Manual firing is effected by the assistant gun-
ner who grasps with his right hand tha auxiliary trigger
handle pulling it upwards and to the rear. The motion of
th!: handle is tra~ismitted through the auxiliary trigger
shaft and lever to the pusher, which through the roller
1ff is the trigger lever, and accomplishing firing, as ex-
pos3d under a/.
The firing accomplished, ad the assistant gun--
nar having swiftly released the handle, the auxiliary
trigger, under reaction of the spring returns to its seat,
and the pusher leans against th3 auxiliary trigger box.
During this action the auxiliary trigger lever under the
action of its spring /in the box/ returns with its longer
arm into lower position, and re-catches the pusher, per-
mitting further firing.
Firing with the auxiliary trigger by means of
th:, lanyard is effected by attaching the latter to the
trigger handle eye, after which the lanyard is abruptly
pulled and released.
c/ Firing with tho assistant gunner's trigger
If the auxiliary trigger is unserviceable, fir--

way of firing may also be done manually or by means of

Manual firing is performed by the assistant gun-
ner, who grasps with his right hand the trigger lock cas-
ing and pulls the lever upwards and to the rear. By this
pull on the trigger lever the trigger shaft is turned in

To carry out recocking., it is necessary to unlock
the handle pulling it with the right hand upwards in order
to get the locking plug out of its seat in the breechring.
After unlocking, the handle is pulled to the left and rear
in result of which the lug of the shaft will press the sear
and turn it into its seats By the turning motion of the
sear the striker is pulled back, the striker spring is corn-
pressed and once the striker rim has passed over the trig-

The hydraulic recoil brake consists of :
- the recoil cylinder
- the piston rod with the piston
- tha counter piston rod with the piston
- tho compensator
- two recoil cylinder stuffing boxes
- a compensator cylinder stuffing box with the
fluid adding valve in the hydraulic recoil
brake, and
- the fluid.
The brake is provided with a recoil-length adju-
ster and with a counter recoil shock absorber on the count-
er piston rod.
a - The piston rod with the piston. The piston
rod is hollow to allow the inserting of the counter piston
rod; attached to its front end is the piston.
b - The counter piston rod with the piston. The
counter piston rod is cylindrical in shape, in its inner
part it is hollow for one half of its length. Screwed on-
to its rear end is the piston with the counter recoil
shock-absorber. In the counter piston rod there are four
longitudinal - roov,es of various cross-sections. Through
two of them passes the fluid during recoil, when firing
with great elevation.
The piston of the counter piston rod is hollow
and in it is the valve with its spring. Screwed onto the
end of the piston is the shock-absorber. The valve with
its spring and the shock-absorber perform the shock-ab-
sorbing during counter recoil.
The valve spring keeps the valve in its seat on
the piston. The valve has the function of permitting the
fluid to pass, during recoil, into the inner part of the
piston rod, and to close the hole on the piston during
so that the fluid flows only through the
counter-recoil,
four holes on the valve into the inner part of the counter-
piston rod.
The shock absorber is screwed onto the piston

tudinal semicircular slots of different depth. The shock-
absorbr guided through tho piston rod by a brass ring,
-teach d to ti-irk piston rod extension.
C - Thr3 cornpan'sator /l{'ig. 22, 20 and 27/ has the
function of receiving the surplus fluid from the recoil cy-
1ind~r, originating from heating in or'E.x to refill the
space from wh?ore thr~ piston retracts in recoil to prevent
building up of a vacuum. The compensator contains appro-
xirlatnly 5o ccm of reserve fluid. The compensator is spring-
activated. It consists of a spring and a piston, the spring
being a spiral one. The piston cons fists of a head, a steel-
ring, a rubber ring, a nut for compressing the rubber ring

In weapons models B-1 and B-1A2 the hydraulic
recoil brakes filled with 1.2 kg of Gy~cerine fluid
'Stool J". Further use of this fluid is prohibited and
must be re?lac~d with the same quantity of Glycerine fluid
"Steol MM".
By weapons having glycerine fluid "Stool J" in
their recoil systems, until the replacement with "Stool MM"
is made, any addition of fluid, if necessary, should be
rlade from the "Stool J" brand, Mixing of these two brands
of fluid is not permissible.
In weapon model B-1A1-I the hydraulic recoil bra-
1:e is filled with 1.2 kg of glycerine fluid "Steol MM" and
any additions in the recoil system must be from this brand.
Both fluids have the identical physical characte-
ristics and therefore when changing frcr.. "S'teol J" to
"Stool MM" no adjustment of the hydraulic recoil brake is
`Lecessary,

b - The s tuf f ing box with the counter-recoil
speed regulator /Fig. 34/ serves for sealing the middle cy-
linder and controlling the speed of counter-recoil and
adding and checking of fluid in the recuperator.
It consists of
. the case
- the shaft
- the shaft spring
- the steel ring
- two rubber rings
- two tightening nuts for the rubber rings
- the steel ring for tightening the rubber gasket
- the shaft spring
- the rubber gasket
- the valve with a spring and nut
- the valve regulator
- the index
- the fluid re-filling valve in the recuperator
providing a passage for the fluid, and
- two attaching screws for attaching the index.
The valve has six holes for the passage of the
fluid during counter-recoil, The valve spring has the
function of pressing the valve against the front ring;
during counter-recoil the valve cannot turn around its
shaft, being fixed by the guiding screw, thus being able
to turn only along the shaft and to move longitudinally.
The valve regulator has; the function. of control-
ling the valve. It shows the markings ; "N" - normal, "0"
- open, and "Z`.' - closed. The regulator is attached to the
shaft. Its action is transmitted to the valve through the
shaft and it brings the valve openings to face the arc-
shaped split in the front ring. If the regulator is in the
"N" position, the fluid can return through three holes, . if
in the "0" position - through 6 holes, and if in the ".Z"
position - the fluid can return only through the clearance
between the valve and the shaft in which case all of the
holes of the valve are closed.

rator is performed by means of the regulator in the follow-
ing manner ;
The regulator shaft spring is pressing the valve
shaft forward with a force which is sufficient to keep the
same always in the forward position in spite of the Com-
pressed azote pressure. Only due to shortage of fluid in
the recuperator, when the floating piston rests on the
shaft, the shaft moves to the rear compressing its spring.
The movement of the shaft to the rear creates a space bet-
ween the fluid adding valve head and the rear surface of
the regulator body box. As soon as the separation of the
valve head from the box is noticed it is the sign of flu-
id shortage in the recuperator. /Method of fluid adding is
described in a separate section/.
C - The recuperator stuf Finn box /Fig.31/ has
the function of sealing the recuperator cylinder on its
rear end.
It consists of the box case, a steel ring, two
rubber rings and two rubber ring tight3ning nuts.
d - The left cylinder front cover closes the
front opening of the recuperator cylinder. It is provided
with a hole permitting the azote to enter the cylinder
during recoil, and to escape during counter-rE3coil in or-
der to prevent bu4lding-up of a vacuum or a compression
during counter-recoil.

of the .piston's motion the fluid is forcing its way through
P.
the holes in the piston and the longitudinal grooves of
E
the counter piston rod in front of the piston. The more
the piston rod moves to the rear the greater a vacuum is
being built up in front of the counter piston rod in the
inner part of the piston rod so that the fluid enters
through the grooves and the through holes into the counter
piston rod, exerting pressure against the valve, opening
the latter and flowing through the shock absorber into the
inner part of the piston rod. Since the diameter of the
counter piston rod Is by 1 mm smaller than the inner diame-
ter of the piston rod, during the motion of the piston
backwards, the fluid flows also around the counter piston
rod itself into the inner part of the piston rod.
The flow openings through which the fluid flows
are the holes in the piston and the grooves in the counter
} i s ton rod, and they are biggest in the beginning and then
they grow smaller with the length of recoil, because the
shorter grooves of the counter piston rod get shallower.The
holes in the piston of the counter piston rod remain un-
changed during recoil. The valve permits the fluid to flow
during recoil and closes the middle opening in the counter
piston rod during counter recoil so that the fluid can pass
only through the holes in the valve, thus retarding the
counter-recoil.
Owing to the retraction of the recoil brake pi-
ston, the compensator fills the recoil-cylinder, during the
recoil, with reserve fluid, thus preventing building up of
a vacuum. During firing the compensator is in continuous
operation. The compensator contains about 5o ccm of reserve

passes through the counter-recoil speed regulator exerting
pressure against the valve, compressing its spring and
flows into the space beyond the floating piston. The pres-
sure of the fluid against the floating piston moves the
latter forward. The floating piston compresses the azote
in the middle cylinder and also in the outer recuperating
cylinder in the left hollow part of the cradle
By passage of the fluid through the valve and by
compressing the azote in the recuperator, the recuperator
helps the action of the recoil brake, at the same time ac-
cumulating energy to return the barrel in battery.
The recoil energy is diminished not only by the
recoil-brake and the recuperator, but also by the muzzle-
brake and by the friction of the recoiling parts,
D. THE POSITION OP THE RECOIL BRAKE A1V~ THE RECUPERATOR
PARTS DURING COUNTER-RECOIL
/Fig. 25/
a - The position of the rocu erator
During counter-recoil the main action is perform-
ed by the recuperator. By the compression of azote during
the recoil, the recuperator has accumulated so much energy,
that the counter-recoil would be performed too violently.
To avoid this, during counter-recoil, tha speed regulating
valve and tI shock-absorber located in the piston of the
recoil brake counter piston rod are acting.
After the barrel has stopped at the end of the
recoil the compressed azote' in the recuperator tends to
expand and with its pressure acts on the floating piston
in the middle cylinder, the main energy is in the recupe-
rator and the force of recoil having been over-come,the
azote in the outer recuperator cylinder tends to expand.
Since the middle cylinder is connected with the outer cy-
linder, the azote exerts pressure a~ inst the floating pi-
in the middle cylinder, too'. The floating piston push-
ston

s the recuperator piston forward, Having free space, the
recuperator piston moves forward, pulling along the recu-
m aerator piston rod, the latter pulling the breechring to
Vrti!rr:"
phi ch it is attached.
From the inner cylinder the fluid does not re
turn through all the holes of the counter-recoil speed re-
gulator through which is passed during recoil.
The counter-recoil speed regulator is designed
to retard the returning of the fluid and to enable the gun
crew to control it.
During the returning of the fluid the counter-
recoil speed regulating valve, under. the action of its
spring, presses against the front ring of the box so that
the fluid cannot pass through the clearance between the
front ring and the valve but must pass through the valve
holes.
The resistance being overcome by the fluid,pass-
ing through the valve, prevents the azote from developing
its full energy at once and from returning the :barrel in
battery too rapidly.
The fluid need not always pass, through all of
the holes, but the flow is regulated by means of the stuf-
fing box regulator of the middle cylinder. By means of the

return the barrel too slowly, which normally happens as
a result of the thickening of the fluid due to low outer
temperature, the regulator must be adjusted to "0", so as
to allow the fluid to pass through all of the six holes in
order to return the barrel more quickly.
If the barrel returns in battery too quickly, as
a result of the deluting of the fluid the to heating up,
the ring of the regulator should b adjusted so that the
mark Z" should face the index. The fluid will then pass
only through the clearance between the regulator shaft and
the valve.
The adjustment of the counter-recoil speed re-
gulator is done with a wrench, bearing in mind that if th3
wrench is turned to the extreme right, the mark "Z" will
face the mark r'N", and in the extreme left position the
index face s the mark 0".
The self-turning of the regulator is ensured by
the index in the manner that the Tatter's latch is engaged
by a corresponding notch which keeps the regulator in the
desired position,
C - The position of the recoil-brake /Fig, 26/
While the recuperator returns the barrel in its
battery position, the fluid in the brake, under the action
of thv recuperator, must pass from the space situated in
front of the piston, and from the inner part of the piston
rod through the hole in the piston into the brake cylinder
beyond the piston.
The brake piston rod being attached to the
breech-ring /the latter being pulled forward by the recu-
perator piston rod!, the brake piston rod with its piston
will move forward.
The brake piston forces the fluid from the cyl-
inder passing through 4e grooves of the counter piston
rod and the piston holes into the bike cylinder beyond
the piston. In the be ginning, the opening holes are smal-
ler and subsequently they become larger, depending on the
change of the depth of the grooves in the counter piston

tbe front of the piston, through the pis ton
of the cylinder, which is behind the piston
and into the compensator.
d -The action of the counter-recoil shock
absorber valvo
From the inner part the fluid does not return
throu h d11 the holos in the valve in the same war as it
has passed during recoil.
The function o f the va 1 v3 Is to soothe the
counter-recoil and to serve as a brake ainst violent
motion of the barrel during returning.
Out of the piston rod the fluid passes through
the holes into the shock-absorber head, pressing against
the valve, closing the hollow part of the counter piston
rod, as a result of which the fluid is able to pass only
through the small valve holes into the inner part of the
piston rod. This passing of fluid through the small valve
holes creates resistance which soothes the recuperating
action.
From the counter piston rod the fluid enters
through three pairs of holes, filling up the grooves in
the counter piston rod and together with the remainder of
the brake fluid passes through the piston into the past of
the cylinder beyond the piston.
e -.The action of the counter-recoil shock
absorber
The counter-recoil shock absorber prevents the
shock of the recoiling parts after completing the recoil,
functioning during the last eight centimeters of counter-
recoil.

and the seat of the shock-absorber, when entering the shock-
absorber, flows through itslongidutinal grooves. These
grooves are of varying dep th as a result of which the open-
ing for the passage of the fluid is largest in the begin-
ning and afterwards smaller. From the moment the shock ab-'`
sorber grooves enter the seat, the holes for the passage
of the fluid successively vanish, until they completely
i
disappear, in which moment the barrel, too, comes to its
initial position.
f - The action of the compensator
/Fig, 24 and 25/
Under the influence of heat created as a result
of rapid firing or high outer temperature, the fluid in
the brake cylinder expands.
The brake cylinder .S entirely filled up with
fluid which increases in volume when heated up and exerts
pressure against the cylinder walls, tending to leak out
along some seal. To prevent this, the brake is provided
with a compensator. The compensator has a reserve of 50
ccm of fluid.
The compensator Yea s the task to receive the
fluid surplus originating from heating up, and to keep
the brake permanently full with fluid.
If during firing the fluid heats up and increas-
es in volume, the fluid surplus passes from the recoil
brake cylinder through the opening into the front portion
of the middle cylinder and presses against the compensator
transmits this pressure to the spring, thus
piston, which
creating space for receiving the fluid surplusa
After the fluid has. cooled down and decreased
in volume, the piston spring liberated from pressure expands, force ush-
s the compensator piston forward and the latter p
es the reserve of fluid back into the recoil brake cylin-
der, keeping it permanently full.
During firing the compensator is in continuous
operation receiving and transmitting fluid for correct
operation of the brake.

g - The action of the recoil-length regulator
/Fig. 26, 36a, 36b and 37/
The recoil-length regulator has the function :
- of automatically controlling the recoil length
at elevations exceeding + 1o0,
- of permitting the gunner in some special cases,
,when there is no sufficient fluid or the fluid is heated
ue, to regulate the recoil length at angles of elevat-
ion ensuring a normal recoil length wii a determined
-propelling charge and barrel elevation.

nut on each part of the rod.
If the index on the carrier is on the "0"/zero/
when the barrel is in horizontal position, than the po-
sition o the parts is such as to produce standard recoil-
: f
ing at all angles of elevation.
To shorten the recoil both lock nuts should be
loosened, after which the adjusting nut should be turned
to shorten the adjusting rod.
BY shortening the rod whose motion is transmit-
ted ovor the pinion and the toothed rack to the counter
piston rod, turning the latter to the left /in regard to

At greater elevations long recoil may result because
in such a case the openings for the passage of fluid are

3 _ Checking of the recoil length re gulatar'
In order to enable the gunner to check the con-
trolling action of the recoil speed regulator, a scale is
provided on the adjusting rod with elevation angles en-.
graved in degrees.
When elevating the barrel, the scale correspond-
ing to elevation of the barrel must face "0" /zero/ on
the carrier. In this case the recoil length regulator
functions correctly. In contrary cases the basic position
of the regulator should be checked /the barrel horizontal,
the basic position mark on the rod facing "0" /zero/ on
the carrier.

14-. Fix the index with two attaching screws
15- Install the connector on the piston rod
16- Fix the piston rod connector with two nuts
17- Reinstall the barrel with the breechring and the
mantle onto the cradle
b - Adding fluid in the recuperator
The recuperator contains approximately 165
grams of reserve fluid. If there is reserve fluid in the
U
recuperator then the recuperating speed regulator shaft is
located in its seatinga If there is a shortage of 14o
rams of fluid in the recuperator the shaft rems in
place and the firing may be continued until the shortage
of fluid in the recuperator exceeds 14o gramso When the
shortage in the recuperator exceeds 14o grams then the
regulator shaft, owing to pressing of the floating piston,
leaves its seating; this being the signal that the short-
age of fluid in recuperator is over 14o grams and there-
fore the fluid should be added. When a total of 165 grams
of fluid is lost, the rc~ ~ulator shaft leaves its seating
for 8 to maximum 11 mm and when it is in this position
the firing must be stopp'edo
Adding of fluid in the recuperator is done un~
der pressure with a pumps To do this proceed as follows
1
- remove the barrel, the breechring and the
barrel mantle,
unscrew the valve safety screw,

- take the pump with fluid and screw it in the
shaft,
- pump the fluid through the valve until the re-
gulator shaft returns in place, and then fill
14o grams of fluid more to reach th:~ standard
quantity of fluid in the recuperator.
C - Supplying azote into the recuperator
gig. 55, 5G/
The recuperator is filled with azdie only after
the adequate amount of fluid has been supplied.
To fill threcuperator with azot e it is neces-
sary to
`l - Bring the cradle into horizontal position
2 - Unscrew the screw and remove the case cover of the
azote filling valve
3 - Unscrew the plug from the three-way fitting
- Screw on the three-way fitting with the azote pressure
gauge
- Screw th:! end Of the hose onto th azote pump or onto
a high pressure azote cylinder
- Connect the azot.~ filling hose with the three-way
fitting
- Loosen the valve for one full turn to the left
- Open the azote supplying cylinder and let the azote
into the recuperator.
0 T ? : If the recuperator is to be filled from a high
pressure azote cylinder, the cylinder valve
should be openedy slowly. If the supplying cylin-
der were opened too suddenly, the azote would
exert too heavy a pressure against the hose and
cause damage. The azote pressure gauge should be
apt and have a scale for greater pressure than
the maximum pressure in the azote container.
- Bring the pressure in the recuperator to 62 ? 1 atm.
-- Close the valve
.- Disconnect the hose from the three-way fitting
>.- Screw the plug into the three-way fitting
?- Install the cover onto the valve case and fix it.

REMARK : When adding fluid special attention should be
given not to add more than prescribed. In case more than
the prescribed quantity of fluid is added, owing to the
impact of the floating piston the middle cylinder shall be
damaged, i.e, its bulkhead driven out. Therefore after fil-
ling the quantity of fluid required to separate the float-
ing piston from the regulator shaft, the balance of 14o
grams of fluid serving as reserve must be accurately weigh-
ed.
When adding or taking out of a determined quanti-
ty of fluid, after the performed work the pressure should
be brought to 62 atm; to do this proceed as follows :
- unscrew the plug screw for the seating of the
threeway tube,
- screw in the conducting tube with the compres-
sed azote bottle and bring the pressure in the recuperator
to its standard,
- screw in the valve,
- remove the threeway tube with the pressure
- screw in the plug into the seat of the three-
way tube of the valve box.
2 - Filling the recoil brake

The hydraulic recoil brake is filled with 1.2 kg
of glycerine fluid "Steol".
The filling of the recoil brake is performed on-
1y after the recuperator has been adjusted, checked and
found qj,n correct condition.
To fill the recoil brake with fluid correctly it
is necessary to :
Give the cradle an elevation of 45?

Assembling of the equilibrator is perfoined by
means of special accessories only which are provided in
the battery set of spares, tools and accessories, in the
manner as described for disassembling.
Locking of the a uilibra tors
Prior to di sassembling the barrel and removing
it from the cradle it is obligatory to lock the equili-
brators.
To perform correctly this operation, the cradle
should be slightly depressed so that the inner tube may
enter into the outer tube as much that the seats for the
locking pins of the equilibrators are free.
When the inner tube retracts, the pin is put in-
to its seat in the outer tube and by means of the elsvat-
mechanism the barrel is elevated so much that the con-
s ng
necting shackle of the steel cable can be removed from
on the cradle trunnion and hooked to the spring
the hook
on the inner side of the carriage body. During the ele-
vation of the barrel, one man lifts the front end of the
cradle.
The unlocking of the equilibra tors is done in
reverse order.

- the unlocking bolt
- the spring of the device, and
- the semi-axle with the shoe.
The action of the sp?ink; dv ce_durin
When the wheel in notion runs against a
higher spot on the road, the semi-axle together with the
wheel lifts, thus turning the spring shaft by means of
the lever. Th:e turning of the spring shaft causes the
spring to expand /strain/ because of its being attached
with one end to tha shaft and with the other one to the
housing. The straining of the spring smoothes the uneven
motions of the wheel, transmitting it to the travelling
axle.
When the wheel bumps into a hole on the
road the side of the gun will go down together with the
wheel because of its own weight, the entire process being
the same as when the wheel runs against a higher spot.
The locking of the spring devices
The spring devices are unlocked when the
springy, n is able to absorb the shocks of the wheels. Ten
devices are unlocked, the locking bolt in the
the sprint
housing gets out of its seat with its top on the semi-
~.ng g
this being the correct travelling position of
axle lever,
the spring.
The spring device are locked when the lock-
entering with its top into the semi-axle lever
ing bolt,
securely connects the semi-axle with the t'velling axle.
by the intermediary of th spring housing.
~'
This is the position of the spring devices
in firing, and in travelling, in the event that any of the
spring devices is broken.
The locking and unlocking of the spring
device is done in such a way, that one man of the gun
with his foot the shoe on the semi-axle,
crew presses do's d the bolt
another man of the crew turning with his han
on the spring housing upwards.

Being that the lever moves. in an arc, It
raises the axle to a certain extent. Movement of the axle
is made possible by means of the joint connection with
the lever and the spherical seating in the front cover of
the spring device.
The movement of the axle is not limited and
therefore by abnormally great shocks greater compression
of the spring occurs.
When the wheel hits sunken ground the
spring expands and pushes the lever which in turn tians?"

- big cuts by which it is almost evident
that plying is exposed to further injuries, may be a good
reason for changing the tyre,
- in the event the wear of the tyres is un-
even owing to inclination of the wheels, and sharp or fan
:shaped edges appear, the tyres should be interchanged and
inclination of the wheels eliminated by chna~ing the bron-
ze bearings.
When the shoe wears to an extent that the
tyre gets smooth in the middle, it should be changed. Such
tyres should be re-condi. oned by vulcanization.
It will not be possible to vulcanize the
tyres on which the wear of the rubber reached the plying.
The pressure in pneumatics should be perio-
dically checked and maintained at its standard of 1.8 atm.
When checking the pressure, t1 valve should also be check-
cad for leakage of air. For determining the press re an accur-
`ata gauge should be used always. This gauge should be pe-
riodicallY checked with the control manometer.
Never should the pr essure' in the tyres be
determined by visual estimation or by kicking the tyre.The
should be checked only when the tyres are cool.
