2.3. Replacing carbon brushes
The machine is fitted with carbon brushes with self-cutoff.
When checking the carbon brushes, make sure they are reinserted in the same
position and can move easily in the carbon brush holder.
When the carbon brushes wear down to a length of 7mm they need to be
replaced with new ones.
Only use original FEIN carbon brushes as this is the only way to ensure
compliance with EMC requirements!
Run in new carbon brushes for 20 minutes without load at the lowest possible
speed.
