Safety Instructions

1. Before a trip, check the condition of the lock mechanisms of

the hood and the body doors.

2. When using the low-freezing fluid, leaded gasoline and brake

fluid, do the following:

- avoid any operations which could lead to penetration of these

fluids or their steams into the mouth cavity;

- do not let to dry the liquid which is occured on the skin, but

wash it off right away with warm water and soap;

- never spill liquids in the interior or indoors. Should spillage

occur, wash off the spilled place with water and ventilate it;

- take off the spilled clothes, wash and dry it outdoors;

- wet with kerosene the carbon of leaded gasoline when scraping it off to avoid penetrating of toxic particles of carbon into the respiratory organs.

3. To avoid scalding, open the radiator cap of the engine cooling system with care.

4. Do not warm up the automobile assemblies with free flame.

5. Cut out the storage battery after driving and also in case of short circuit of wiring.

Precautions

1. Do not begin driving the automobile with the cold engine. After starting the engine from cold, never run it at a high crankshaft speed.

2. Cut in the oil cooler at an ambient temperature above 20

C, and when riding under hard service conditions (at heavy loads and a high crankshaft speed) independing on ambient temperature.

3. Shift the gearbox in the reverse gear and shift the transfer case

to low range only when the automobile is stationary.

4. When descending a steep downhill:

- do not shut down the engine to avoid loss of the efficiency of

the brakes provided with the vacuum booster;

do not disengage the clutch to avoid breaking of the clutch

driven disk.

5. When riding on dry hard-surface roads, disengage the front

axle. When the front wheels are disengaged, never engage the front axle.

6. If one of the hydraulic brake circuits is a failure, the travel of the brake pedal is increased, and the braking efficiency is decreased.

7. When using the gun with the unscrewed tip, take out the spring and the ball in order to avoid their falling in the assemblies with liquid grease.

8. Avoid falling acides, soda solutions, braking fluids, antifreeze and fuel on the painted surfaces of the body and rubber parts.

9. Do not allow impact loads on the chassis of the automobile. When a strong impact of the front wheels is occured, inspect carefully the wheels, all parts of the front axle, steering rods, steering mechanism, oil sump, eliminate deffects, if required.

10. To avoid heavy loads on the axle differential, do not allow a prolonged slipping.

11. Use the warmth-keeping hood for radiator shell to provide the proper temperature condition for engine at an ambient temperature below 0 °C.

12. When the automobile is to be operated at a temperature below -30 °C, do not fail to disengage the front axle.

13. The automobile is provided with a towing hook allowing a short-time operation with a trailer. Do not tow a trailer on rugged ground.

14. Do not transport at the same time passengers and cargoes (except for a hand luggage) in the passenger and the sanitary compartments of the automobiles ÓÀÇ-2206, ÓÀÇ-3909, ÓÀÇ-3962, in the cargo compartment of the automobile ÓÀÇ-3741 equipped with the hinged seats, on the platform of the automobiles ÓÀÇ-3303, ÓÀÇ-33036, ÓÀÇ-39094, ÓÀÇ-39095 equipped with the hinged seats and the tarpaulin.

The automobile design is provided with special parts to fasten cargoes.

15. Since efforts are continually made to improve the reliability and performance of the automobiles, minor changes may be introduced without special notices.

laid down in the service book.

Before driving automobiles from the Manufacturer to Distributors/Dealers, it is necessary to carry out all the operations laid down in the section "Daily Maintenance".

The automobile service life depends to a greater extent on the operating mode during the initial service period. The runningin kilometrage is equal to 1000 km.

AUTOMOBILE RUNNING-IN

During the running-in period, observe the following rules:

1. Do not overload the automobile.

2. Do not move on hard-surfaced roads (deep mud, sandy

soils, steep up-grades etc.)

3. Do not exceed the following speed limits:

in direct gear .......................... 45-50 km/h;

in the third gear ...................... 30 km/h;

in the second gear .................. 20 km/h;

in the first gear ....................... 12 km/h.

4. Do not change oils filled in the engine and units at the

manufacturing plant.

5. Check the temperature of brake drums and in case of raising the temperature, adjust them in compliance with the instructions laid down in the section "Brakes".

6. Check the temperature of wheel hubs and in case of raising the temperature, loosen the tightness of bearings.

7. Check condition of all attachments. Check the connections of pipes; if oils, fuel, coolant and hydraulic fluids leak, eliminate defects.

It is forbided to increase a crankshaft speed for warming-up the engine.

Starting from Cold at Temperatures of 0°Ñ to - 20 °Ñ. Before starting the engine, carry out the following operations:

1. Close the radiator shutter and mount the radiator shell

warmth-keeping cover.

2. Using the starting handle, turn over the engine crankshaft

for 3-5 times.

3. Pull the choke control knob all the way out (preliminary,

the throttle valve control pedal should be pressed).

Carry out the subsequent operations in the order specified for starting the engine at temperatures of 0 °Ñ and above.

After the engine is warmed up, push the choke control knob all the way in.

Starting from Cold at Temperature Below - 20 °Ñ.

Before starting the engine at a low temperature, warm it up (by means of hot water, steam or air etc.).

Before starting the engine, it is recommended to warm up the transistor commutator, for this purpose switch on the ignition, and start the engine in 3 minutes.

Carry out the subsequent operations in the order specified for starting the engine at temeratures of 0 °Ñ to -20 °Ñ.

Starting from Hot.

When starting from hot, do not push the choke valve control knob in, and the throttle valve control pedal is not be sharply depressed, as it results in overenrichment of the air-fuel mixture, and the engine fails to be started.

To eliminate the overenrichment, blow through the engine cylinders with air for which purpose smoothly depress the throttle valve control pedal up to the toeboard, and immediately turn over the crankshaft by means of the starter for several times.

Shutting down the engine

Before shutting down the engine, let it run for 1-2 minutes at a low crankshaft speed for gradual and uniform cooling and thereafter switch off the ignition.

FEATURES OF DRIVING UNDER DIFFERENT

ROAD, METEOROLOGICAL AND CLIMATIC

SERVICE CONDITIONS

The operation and service of automobile depends to a greater extent on features of its driving. When driving correct, the automobile could run at a high middle speed and consume not

much fuel when overcoming almost impassable sections of roads. We recommend to shift in the second gear for starting the

automobile away from rest on level sections of roads or on downgrades. In other cases, shift in the first gear for starting away from rest. Disengage the clutch when shifting in gears.

Move the gearshift lever smoothly and without jerks. If a required gear is not shifted before starting the automobile away from rest, release the clutch pedal gently, and then disengage the clutch again and shift in a gear.

Shift in the reverse gear only after a complete stop of the

automobile. When operating the automobile, do not keep the

foot on the clutch pedal, as it would result in clutch partial disengaging and disk slipping. On slippery roads, drive the automobile evenly, with a low speed.

When braking engine, release completely the accelerator pedal.

Brake the automobile smoothly by depressing the braking pedal slowly. When braking unnecessarily, the tyres are worn quickly, and the fuel consumption is increased. When braking, do not allow slipping the wheels, as it decreases the efficiency of braking (in comparision with braking during rolling) and increases wear of tyres. Besides, sharply and heavy braking could provoke skiding of the automobile.

When the automobile is to be operated on off-the-road (sand, mud, snow etc.), slippery roads, steep up-grades (more than 15 °Ñ) and on other complicated sections of roads, do not overload the engine. In this case, engage the front axle, and on very complicated sections of roads, shift also the transfer box to a low range. Before engaging the front axle, engage the front wheels. Engage the front axle in motion, and shift the transfer box to low range only after a complete stop of the automobile.

Overcoming Steep Up-Grades and Down-Grades. When driving on roads with steep up-grades and down-grades, a driver should be very intent. Determine preliminarily an up-hill gradient and shift in a required gear which would ensure a required traction force of wheels. When overcoming steep upgrades, shift the transfer box to a low range and the gearbox in the first gear. Overcome up-grades without stopping and turnings, as far as possible. Overcome short up-grades provided with a convenient access and smooth riding surface by speeding
