2. Step on the accelerator pedal and pull out the carburetor choke knob as
far as it will go. Release the accelerator pedal. If you do not stick to the above
sequence, the choke rod can be broken.
3. Depress the clutch pedal all the way down.
4. Turn on the starter for not more than 10 seconds.
5. As soon as the engine starts, release the key and the clutch pedal. As the
engine warms up push in the choke knob gradually into the initial position.
Should the engine fail to fire after the first attempt, allow 1 minute before
the second attempt. The second attempt will be possible after turning off and
repeated turning on of the ignition only. After two/three unsuccessful attempts,
set the carburetor choke knob into the initial position, depress the accelerator
pedal all the way down and crank the engine by the starter for 5–10 seconds.
If the engine fails to start, check the fuel and ignition system and eliminate the
trouble.
Before starting the engine from cold in winter depress sharply the acceler
ator pedal (1–2 times) to enrich fuel mixture.

of its travel. Do not close down the choke as this produces an excessive
ly rich fuel mixture and makes proper starting difficult.
Engine stopping
is carried out by turning the ignition key into position
“0”. If the engine has been operated in heavy duty cycle its instantaneous shut
down is not allowed. Let it run for 2–3 minutes at idle speed.
8.1.2. Starting and stopping of ZMZ40522 engine
Prior to engine starting check the levels of coolant in the cooling system
and oil in the engine crankcase.
Start the engine
in the following sequence:
1. Move the gearshift lever into the neutral position.
2. Depress the clutch pedal all the way dawn.
3. Turn on the ignition. Warning lamps

should light for 5–10 seconds and then go out. Its
continuous lighting (for more than 15 sec.) indicates that the engine control
system is out of order. However in most cases backup control modes make it
possible to start the engine and keep on driving up to the service station or
garage (system operation in the backup mode does not produce a significant
negative effect on the engine but its pickup becomes worse and the fuel con
sumption increases in the process).
