mechanism gets weak, or if the carbon brushes switch off.
When carrying out maintenance all parts of the maintenance set 9170 3168 90 must be exchanged.
With the exception of the electrical parts all parts must be cleaned with cold cleanser.
Attention! No cleanser must enter the encapsulated bearings.
Clean the electrical parts with a dry brush.
Check the dismantled parts for abrasion (visual check) and exchange if necessary.
Before assembly submit all relevant parts to an electrical examination (see chapter Electrical and
