3.24. Check of a state, adjustment and replacement of brushes of screen wipers
On brushes of screen wipers the road film collects over time, reducing efficiency of their work therefore brushes should be washed out regularly in the soft cleaning solution.
Assemblies of screen wipers with brushes should be examined regularly. If survey revealed existence of hardenings or cracks on rubber of brushes, replace them. If at survey nothing unusual is revealed, wet a windshield, include screen wipers, let's them work a little, and switch off them. Or strips on pure glass indicate an uneven trace from brushes on glass that brushes should be replaced.
If brushes insufficiently well clear a windshield, then hit on glass of particles of wax can be the cause of it when passing by the car of an automatic sink. These particles can be removed at addition in liquid of windscreen washer of the detergent having property to dissolve wax.
Filling of the tank of a washer of glasses liquid with voskorastvoryayushchy properties can significantly improve action of screen wipers. Fat-dissolving cleaners are not able to purify glass completely.
During operation of the mechanism of screen wipers there can be a weakening of fixing nuts therefore they should be checked and as necessary to improve every time when checking brushes (see more detailed information on the mechanism of screen wipers in the Head Onboard electric equipment).
Moisten glass with water and put screen wipers in action. Check brushes of screen wipers for lack of jingle.
