For protection of the electric motor against overloads in a cleaner the thermobimetallic safety lock is established.
The cleaner works in three modes:
The I mode – faltering, is provided to the electronic R1 relays installed in the assembly block. This relay also includes a cleaner motor-reducer (small speed) at inclusion of a washer of a windshield;
The II mode – constant, with a small speed of the movement of brushes;
The III mode – constant, with a high speed of the movement of brushes.
