REPLACING CARBON BRUSHES
The carbon brushes are a normal wearing part and
must be replaced when they reach their wear limit.
CAUTION: Always replace the brushes as a pair.
To replace:
Remove the four screws and remove tail cover.
Using pliers, rotate the brush spring out of the way
and slide old carbon brush out of the brush holder.
Unscrew the screw to remove the brush lead. The
old carbon brush many now be lifted away.
Install a new brush. Installation is the reverse of
removal.
Replace the motor tail cover.
NOTE: To reinstall the same brushes, first make
sure the brushes go back in the way they came out.
Otherwise a break-in period will occur that will
reduce motor performance and increase brush
wear. It is recommended that, at least once a year,
you take the tool to an Authorized Service Center
for a thorough cleaning and lubrication.

unexpected starting or electrical shock, unplug
