immediately after it stops.
10. The fuel pump's electric motor is cooled by the flowing flow of fuel, therefore, in order to avoid its failure, it is
not allowed to
turn the electric fuel pump “on dry” when there is no fuel in the left tank.
11. It is forbidden to start the engine with improperly installed high-voltage wires from the ignition coils to the spark
plugs or with low-voltage wires to the ignition coils.

CAUTION! Motor gasoline and its vapors are toxic and flammable. Observe the following rules:
-
observe the rules of fire safety;
- avoid any operations that may result in gasoline entering the oral cavity;
- do not let dry the gasoline that has got on the skin, and immediately wash it off with warm water and soap;
- cover the spilled gasoline with sand or chips, brush off and dispose of, ventilate the room;
- take off any clothing contaminated with gasoline, dry it outdoors, and then wash it.
CAUTION! Only use the recommended unleaded gasoline (Lead contained in the leaded gasoline causes failure of
the oxygen sensor in the exhaust gases and the catalyst).
Fuel is supplied to the electric fuel pump from the left tank. As fuel is running out, the left tank is automatically
refilled from the right tank.
Fuel tank filler neck plugs are blank and ensure a tight seal.
