Check of a state, replacement of brushes and adjustment of a corner of screen wipers

1 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.

Check of a condition of brushes and starting position of the lever of a screen wiper

2 Assemblies of screen wipers with brushes have to look round regularly. If survey revealed existence of hardenings or cracks on rubber of brushes, replace brushes. 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.
3 If brushes insufficiently well clear a windshield, then the following reasons are possible:

When passing by the car of an automatic sink on a windshield wax particles got. These particles can be removed at addition in liquid of windscreen washer of the detergent having property to dissolve wax.
Filling of the tank for liquid means for cleaning of glasses with voskorastvoryayushchy properties can significantly improve action of screen wipers. Fat-dissolving cleaners are not able to purify glass completely.
At damage of brushes, they should be replaced.
The angle of installation of levers of screen wipers does not correspond to necessary.
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 tighten every time when checking brushes.


4 Switch on and off screen wipers, at the same time they will be established in a starting position.
5 Check distance between an elastic band of a brush of a screen wiper and the basis of glass which has to be 20 mm on a windshield.

Check and adjustment of a corner of the lever of a screen wiper

Check of a tilt angle of the lever of a screen wiper needs to be made at low efficiency of purification of glass or if brushes in the course of work move unevenly or vibrate. Adjustment requires the special HAZET 4851-1 tool.


6 Install screen wiper levers in a starting position. For this purpose moisten a windshield with water. Include for a short time a screen wiper and stop it the switch.
7 Remove a brush.

8 Take away the lever-2-. Install the special HAZET tool and fix it the screw-3-.

9 Carefully take away the lever back. The HAZET tool has to adjoin to glass in three points.
10 Check the angle of installation on a scale of the tool and compare to the required value.

The required value: -3 ° ± 2 °.


11 Take away the lever from glass a little and turn a wrench on 24 mm-1-a little.

12 Check the angle of installation again and if necessary modify it so that on a scale there was a required value.
13 After that remove the tool, once again establish and fix it. Again check the angle of installation, if necessary modify.
