The cleaner has two modes of operation: continuous and intermittent, which is provided using a relay type RS-514.
To protect the motor-reducer from overloads when the brushes freeze to the glass or when there is a high resistance to their movement, a reusable thermal bimetallic fuse is installed in the cleaner.
The washer pump is integrated into one unit with an electric motor and is installed in the engine compartment on the washer reservoir. The pump motor is turned on by the right lever of the three-lever switch when it is pulled «to myself».
