The carbon brushes are worn when the pressure springs
come to rest on the retainer without the carbon brush-
es reaching over their guide way.
They are also to be replaced when the contacts (10)
appear black and dull. – On intact carbon brushes the
contacts are anthracite coloured and shining.

Do not touch the friction surface of the carbon
brushes!

carbon brush retainer and check the next one.

verse order to chapter

also to be checked for damages. – To check them remove a
carbon brush retainer.

The slight grinding marks caused by the carbon brush-
es correspond to their normal wear and have no influ-
ence on the performance of the motor. Extreme recess-
es have to be smoothed out. If partial segments have
been broken out or are extremely burnt the drive unit
has to be replaced.
