- prior to electric arc welding, be sure to dismantle fuel tanks;
- observe fire safety rules.
24. Used oils and special liquids must be collected and sent for
recycling or disposal.
25. Several safety requirements are detailed in the respective
sections of this Manual.
WARNINGS
1. During the initial operating period, all the recommendations
specified in the section "Running the New Motor Vehicle" must be
strictly observed.
2. Do not drive off with cold engine. Avoid high crankshaft rpm
after a cold start.
Warming up the engine at high crankshaft rpm for faster heat-
up is forbidden.
To avoid any difficulties during engine start, strictly observe
instructions specified in the section "Engine Start".
3. When abnormal noises and knocks arise in the running
engine, the cause should be investigated. Do not operate the motor
vehicle until the fault is eliminated.
3.1. Upon cold start, knocking in hydraulic pushers of valves
may arise, caused by the suction of the air into the high-pressure
chambers of hydraulic pushers. Typically, these phenomena appear
in the following cases:
- cold start;
- multiple starts (after several unsuccessful starts);
- engine start after a long time of standing still.
To remove the air, the engine must be warmed up to the cooling
fluid temperature of 80-90°C. Let the engine run at constant rpm
of 2,500 ±100 rpm or at variable rpm within 2,000-3,000 rpm
for 3-4 minutes, then listen for 15-30 seconds the operation of the
engine when running idle. If the knocking persists, repeat the cycle
up to 5 times. If the knocking persists after the above precedures
are completed, you need to contact a service station to eliminate
the malfunction.
4. To ensure reliable operation and to prevent accelerator pedal
failure, we recommend:
- not to apply excessive loads to the pedal lever after its operating
stroke ends;
