2 Safety requirements and precautions
2.1 Safety requirements
2.1.1 Before you start working, make sure that the truck and its coupling devices are in
good working order.
2.1.2 While driving the vehicle, the driver and passengers must wear seat belts.
2.1.3 Do not start the truck engine, without making sure that the gearbox is in neutral.
2.1.4 Service and repair the truck on a level ground, after having braked the parking
brake by disconnecting the batteries using the switch and placing wheel chocks under the wheels.
2.1.5 Keep the engine and starting preheater clean and maintain their working order,
make sure there are no fuel and oil leakages: this may cause fire. During the preheater operation,
do not leave the vehicle unattended.
2.1.6 In the process of filling the truck with fuel, the pre-heater must be switched off.
2.1.7 Do not warm up the engine, if the truck is indoors, and ventilation is poor.
2.1.8 Coolants (low-freezing) and brake fluids are toxical: handle with care.
2.1.9 To climb the truck front bumper and descend it, use the step plate, central and left-
most (in direction of travel) grille ribs having on the inserts on the inner side, as shown in Figure
4. 2.1.10 When servicing the engine, fix the hood lifting mechanism with a safety hook 1
(Fig.5). 2.1.11 Before dismantling the wheel put the wheel chocks under the unlifted axle wheels
in order to avoid the vehicle self-motion. Unfasten the wheel nuts, hang out the wheel with jack or
other hoisting device, unscrew the nuts and dismantle the wheel.
To lift the front axle with the jack, insert its screw head in the spring clamp socket; to lift

extending the rope across the road, put a guard and warning signs prohibiting to pass.
2.1.26 When using the independent air heater keep in mind that the heater mishandling,
as well as heater failures, are the sources of extreme fire danger and may cause exhaust fumes
poisoning.
Prohibited:
- leaving the working heater unattended;
- using the heater with faulty wiring (electric junction sparking);
- using the heater when the inlet and exhaust branches are partially or completely over-
lapped; - opening the case top cap when the heater is working and touch the hot components;

11
- placing explosive and inflammable substances or devices (e.g. spray bottles, etc.) in the
heater heat flow area;
- using the heater in an unaired area;
- using the heater with the damaged fuel supply system;
- starting and using the heater poured over with fuel;
- switch on heating when transporting flammable cargoes at temperatures above minus
5°Сin order to avoid fire;
- switching on and using the heater near gas-filling stations and other places with in-
flammable vapors or significant amounts of explosive dust (carbon, wood dust, etc.) in the air.
Keep the independent air heater switched off at gas-filling stations and during fuel tank-
ing. In case of the fuel ignition, switch off the independent air heater immediately and use the
fire extinguisher if necessary.
Attention! Do not extinguish burning fuel with water.
2.1.27 If burnout loss signs or fuel and combustion products smell is detected in the cab,
switch off the heater. Further operation of the heater is possible after removing the causes occa-
sioned the exhaust gases penetration in the cab.
2.2. Precautions
Proper operation of the truck and its long service life can be ensured if you observe all
recommendations given in this Manual.
2.2.1 Before operating the truck, you should carefully read the section "PRECAU-
TIONS", "SAFETY REQUIREMENTS".
2.2.2 When running the first 1000 km (50 hours of engine operation), comply with the
rules described in Section “New Truck Running-in”.
2.2.3 Before starting the engine, you must carefully read the section "Power unit start,
operation and stop" of the power units operating manual.
2.2.4 To prevent air penetration in the fuel feed system do not burn all the fuel from the
fuel tank.
2.2.5 See that the preheater fuel pump is adjusted correctly, not allowing open flame in
the gas conduit of the heat exchanger.
2.2.6 Do not allow the preheater to operate for more than 15 sec without a coolant in the
heat exchanger. Upon washing the truck or its fording, engage the pump unit for 2-3 min to re-
move water from the preheater air duct.
2.2.7 Warm up the engine till switching on all the cylinders and changing the engine
speed when changing the fuel supply; start travelling at low gear.
It is recommended after the engine start for its uniform heating and increasing the tem-
perature in the cab, start traveling at low gear after the coolant has been heated up to 40 °C.
The optimum temperature of the working engine coolant should be 75-100 °C.

12
2.2.8 To drain the fluid from the engine cooling system completely, place the truck on a
flat site or incline it forward.
2.2.9 Drain the coolant from the engine cooling system through three cocks (on the heat
exchanger, on the pump unit and on the water pump inlet branch) with the open cab heater cock
and the open plugs of the radiator and preheater filling pipe. If water is used in the engine cooling
system in an emergency situation, remove the rest of water from the preheater liquid pump by en-
gaging the pump unit for 10-15 sec to avoid the fan impeller freezing-on. Upon draining the fluid,
close the cocks.
2.2.10 Transfer gearbox and rear axles differential lock switches should be in «off» posi-
tion when the differentials are unlocked.
2.2.11 Shifting gears in the transfer case is only allowed after the vehicle full stop.
2.2.12 Cross-axle differential locking is to be used in certain conditions only as per
«Truck Driving» Section.
2.2.13 Lock and unlock differentials after the vehicle has been completely stopped. If the
differentials failed to lock, it is necessary to pull away smoothly and drive the vehicle at a speed
not exceeding 5 km / h till the differentials lock, performing the interaxle differential locking.
2.2.14 With a cross-axle differential locked, drive the vehicle at speed not exceeding 20
km/h on the straight only.
1.2.15 When driving out of a rut, do not go for a long time with the steering wheel turned
in the extreme position since oil can be overheated in the hydraulic system and the pump may be
broken. For the same reason, when taking off power in steady-state condition, release the steering
control shaft by turning the steering wheel until it turns freely.
It is recommended to set the steering gear sliding valve to the neutral position in the fol-
lowing order:
- when the engine is running turn the front wheels to the extreme left or to the extreme
right position and release the steering wheel;
- stop engine;
- after wheels partial self-return, set the steering wheel to the middle position within free
motion at that wheels position.
Having performed these actions the engine can be started and the vehicle can be operated
in steady-state conditions.
2.2.16 Before the truck starts travelling, the air pressure in the brake system should be
not less than 440 kPa (4,7 kgf/cm
2
). If alarm lamp 3 (see Fig.20) on the dashboard turns on, rem-
edy a fault occurred in the pneumatic part of the drive.
2.2.17 Before travelling, check if the alarms of the pilot lamp assemblies (see Fig. 20) are
in good working order 9.
2.2.18 Do not use the truck with the lowered tailgate, because in this position it closes the
rear signalling lights.
2.2.19 If the engine has not been started or has stalled by any reasons, first set the key
into its initial upright position, than switch on the starter in 1–2 min.
2.2.20 Frequent starting of the engine with its short-term operation result in quick dis-
charge of the storage battery.

13
2.2.21 Do not move the truck using the starter: this may cause starter breakdown and
quick storage batteries discharge.
2.2.22 To avoid generator breakdown attach the starter cable to the positive terminal of
the storage battery and attach the storage battery switch cable to the negative terminal..
2.2.23 Attach cables to the generator set according to the marking.
2.2.24 Prior to removing the generator from the engine switch off the storage battery.
2.2.25 During long-term parking of the truck disconnect the storage battery from the
“ground” with the help of the “ground” switch button 37 (see Fig. 18).
2.2.26 When starting the engine from an external source, it is required to switch on the
storage battery. It is prohibited to use a direct-current source with ratings exceeding 24 V at a cur-
rent of 0 (zero) A and 18.3 V at a current of 1000 A and the storage battery that has a rated capac-
ity different from 190 A.h by more than
+
20 A.h.
2.2.27 Removal of the seals from the speedometer and speedometer sender in the warran-
ty period without the permission of the manufacturer drive flexible shaft deprives a customer to
make any claims.
2.2.28 At an ambient temperature lower than –25 °C use an auxiliary power take-off
only after a short run (approximately 15 km) or warming-up of the oil in the transfer box by oth-
er method, for example, by hot air.
2.2.29 During the truck travelling the wheel valves of the tire pressure control system
should be opened. When the truck has been parked for a long time, close the wheel valves. At an
ambient temperature lower that –35 °C open the wheel valves 15–20 km after beginning of travel.
Upon opening the wheel valves blow through the tire pressure control system with the air from the
tires (see the Section “Central Tire Pressure Control System”).
2.2.30 When towing, in order to avoid the gearbox failure, engage the neutral gear in the
transfer gearbox. Towing is performed limiting the maximum towing speed to 50 km/h.
2.2.31 Manoeuvring, particularly while reversing, do not allow big angles of the road
train folding to avoid damage of the drawbar.
2.2.32 When using a trailer at an ambient temperature less than -25 °C, do not leave the
rubber buffer of the drawbar under load before a long parking to avoid freezing of the pressed
rubber bumper and appearing an axial clearance in the drawbar. Disconnect the trailer or unload
the axial load from the rubber buffer by moving the truck forwards and backwards.
2.2.33 When a loader having a total weight exceeding 3200 kg is running onto the truck
platform, put shields (boards) under its wheels.
2.2.34 Put heavy small-sized cargoes, which can cause local sagging of the platform floor
or damage the body sides and seat components, onto sills (boards) and fix them securely. Place
the cargo so that its centre of inertia is located in the middle of the truck platform.
2.2.35 If after parking the truck for a long time or for the reason of high air leaks, the
complete air leakage occurred and the gear is engaged, it is necessary to disengage the gear (set-
ting in the neutral position) by alternate turning the engine crankshaft to the right and left through
approximately 180
o
, using the technique described in the Section “Adjustment of Valve Timing
Mechanism” of the engine Operation manual or release the clutch by filling the pneumatic system
by the compressed air with the help of another truck via the towing valve.

14
2.2.36 Transportation of goods or towing trailers (or transport means) exceeding the max
weights indicated in the Operation Manual is not admissible.
2.2.37 After a long-term travelling in snowfall conditions or on snow-covered roads —
remove the air filter cover and shake out the snow from the filter compartment.
2.2.38 When operating the truck with a trailer it is not admissible to:
- use a towing coupler on GOST Р41.55-2005, if the control pin projects relative to the
handle (see the Installation and Operation Instructions «Towing coupler 21-202», Section «Opera-
tion and description», subsection «Coupling control»).
- use a towing coupler on GOST 2349-75 with unsecured latch of the towing hook by the
locking pin (see «Running Gear» Section).
2.2.39 Using tires of different manufacturing plants on the same truck is not admissible.
