3.6.3 Replacing carbon brushes
• See fig. 020707040.
The carbon brushes of the drive units should be replaced as
follows:
• Remove the drive unit; see 'replacing drive unit'.
• Slide the rubber cover (A) to the back onto the drive
unit.
• Slide the cover (B) of the carbon brush holder
backward.
This way, the carbon brush (C) becomes accessible
and can be taken out.
• Inspect the carbon brush and replace it if necessary.
• Also check the collector on the rotor of the motor
through the open carbon brush holder.
• In case of serious wear of the collector
the drive unit must be entirely
replaced.
• Do NOT make repairs on the drive unit,
because this will make the guarantee null and void.
• Mount the carbon brush into the holder. This can be done in one way only!
• Mount the sliding cover onto the carbon-brush holder.
• Replace the drive unit; see 'replacing drive unit'.
Make sure that the sliding plugs of the connecting wires, on the drive unit, are properly connected.
