There is a danger of traumatizing!

At an open cowl and the working engine there is a danger of traumatizing.

After switching off of the engine rotation of blades of the electric fan of a radiator within about 30 seconds is possible.

The engine is equipped with electronic system of ignition. In view of the high voltage of system of ignition it is very dangerous to touch elements of system of ignition (the ignition coil, the ignition distributor, a wire of high voltage, tips of spark plugs, the control socket):

· At the working engine,
· At start of the engine,
· When the key in the lock of ignition is in situation 2 and the crankshaft of the engine is turned by hand.

Opening

1. Rychazhok pull in the direction of an arrow - the cowl is released.

2. Extend the handle-2-from facing of a radiator and open a cowl — do not lift for the handle.
You watch that levers of a screen wiper were not in the cast-away situation.

Closing

1. Slam a cowl. At the same time you hold hands only edges-3-.

2. If the cowl was not recorded, open it once again and slam with a bigger force.
