2. USEFUL HINTS
1. Procedure of engine starting is described in section 6.2. "Engine Start
ing and Stopping".
After cold engine starting do not run it immediately at high speed because
cold oil passes slowly to rubbing surfaces and they may be got damaged at the
engine high speed.
2. The engine efficient performance and its wear mostly depend on engine
operating temperature. It is necessary to maintain coolant temperature within
the limits of 80–95° C. At the ambient air temperature of 5° C and below in
stall cold weather radiator cover.
3. Do not operate the starter continuously for more than 15 seconds. For
the second attempt of engine starting, allow not less than 30 seconds. Not more
than three engine starting attempts are permissible. Should the engine fail to
fire after these attempts, check the starter power circuits, the starter itself, the
engine fuel system and the storage battery for good condition.
Never move the vehicle using the starter and turn on the starter with the
running engine.
4. After cold engine starting do not run it at high speed. Warm the engine
up at 10001400 rpm. Never drive the vehicle with cold engine. Coolant tem
perature before starting movement should be not less than 40° C.

5. If the engine has been operated at heavy duty cycle let it run for 3 min
utes at idle speed before stopping to decrease smoothly the temperature of tur
bocharger to avoid its premature damage.
6. To prevent damaging of the gearbox when towing the vehicle, discon
nect the propeller shaft flange from the axle drive. Then fix reliably the dis
connected end of the propeller shaft via a wooden block to the vehicle nearest
frame element.
7. Do not eliminate free axial displacement of steering arm pin ball head as
to drag link because the travel equal to 3,4 mm with the shutdown engine is
required for power steering drive proper operation.
8. To avoid dislocating of relative position of the steering gear and steer
ing wheels, never set out the adjustment of the drag link length (except for the
cases specified in given Operating Instructions).
9. To avoid overheating of power steering drive system, do not run the en
gine for a long time at high speed (more than 30 minutes) when the vehicle is
at parking place.
10. With operating engine do not keep the steering wheel turned as far as
it will go for more than 15 sec. because it may cause damage of the power steer
ing pump. Never start the engine with power steering tank empty or insuffi
cient oil level.
11. When the ambient air temperature is below 35° C fill the power steer
ing system with special liquid (see subsection "Lubrication Chart").
12. Watch out for tightness of air pipelines, cylinders and pneumatic valves.
Break of air tightness reduces braking efficiency.
13. To avoid storage batteries failure, timely switch over regulated volt
age level.
14. If any of the red pilot lamps lights up on the instrument cluster or buzzer
operates on the run, stop the vehicle, detect and eliminate the trouble.
15. The brake pads are to be replaced at service stations only.
3. SAFETY PRECAUTION RULES
Strictly follow the safety precaution rules during vehicle operation.
Never warm up the engine in the enclosed space. The engine exhaust gases
contain toxic end product of fuel combustion, monoxide carbon including (gas
without fume and color), which, when inhaling, causes severe intoxication and
it may even lead to fatal case. It is also not recommended to turn on the pas
senger compartment ventilation at parking place with the operating engine.

To gain access to the rear passenger seats, the front passenger seat to be
moved in the direction of the driver seat. This seat shifting mechanism is simi
lar to that of the driver's seat. Before driving the vehicle shift the passenger
seat to the extreme right position by all means, otherwise safety belt will be
ineffective.
Seat belts are effective equipment to protect the driver and any passen
gers from severe injury in road accidents.
Vehicles are equipped with two types of seat belts. Inertia reel type with
three anchorage points for driver and passengers of single and outer seats as
well as lap type with two anchorage points for passengers of centre seats. Ad
justment of the inertia reel type belts is not required. As for the lap type belts,
personal adjustment of its length is necessary because intimate mating of web
bing to hips must be ensured. Changing of webbing length is performed by
means of regulator.
To fasten the belt (Fig.6.3) it is necessary to pull the belt webbing slow
ly by the tongue over the shoulder and across the chest and push it into the
buckle nearest the wearer; a click will indicate that the belt is locked.
Upper portion of the belt should pass across the centre of the shoulder so
that it is not resting on your neck or under the arm and must have intimate
mating with the upper part of your body.
Fig. 6.3. Fastening by Seat Belt
Lap portion of the belt should be positioned as low on the hips as possible.
Otherwise release the belt and adjust its length.
To release the belt, press the red panel on the buckle. The belt will auto
matically retract to its stowed position.
Pregnant women should also wear the seat belt. But she should position
the lap portion of the belt low so that it does not come across the abdomen.
