2.3. Carbon brush replacement
The machine is equipped with carbon brushes that switch off automatically.
When checking the carbon brushes, make sure that they are reinstalled in the
same position and move easily in the carbon brush holder.
Once the carbon brushes wear down to a length of just 7 mm, replace them
with new carbon brushes.
Only use original FEIN carbon brushes, otherwise EMC requirements may not
be fulfilled!
Begin by 'wearing in' the carbon brushes for 20 minutes without load at the
lowest possible speed.
