The cleaner has three operating modes which are switched on by the right polru-left switch. The faltering mode is provided to the electronic relays of 523.3747 type installed in the assembly block. The relay also includes the small speed of a motor-reducer of a cleaner at inclusion of a washer of a windshield. The relay has to provide turning on of the electric motor with a frequency of 14±4 cycles a minute with a frequency of rotation of a shaft of a motor-reducer not less than 20 ^min.-1, temperature of (20±5) °C and supply voltage of 14±0,2 Century.

During the work of a cleaner at a small speed in the constant mode supply voltage is brought to opposite brushes. During the work of a cleaner at the maximum speed "plus" of food is brought to the brush located sideways.

The faulty motor-reducer is recommended to be replaced new.

The electric pump of a washer of a windshield is installed on the tube connected to the union of a polyethylene tank. The tank is installed in a motor compartment at the left. Nozzles of a washer are located on a cowl, flexible connecting hoses are attached by brackets to amplifiers of a cowl.

At malfunction of the pump it is replaced. The got littered nozzles can be blown in the opposite direction or to clean a scaffold.
