To replace motor brushes:
1. DISCONNECT TOOL FROM POWER!

and worn brushes from motor.
This tool is equipped with a universal
motor that uses two carbon brushes to
transmit electrical current inside the motor.
These
brushes
are
consid-
ered to be regular "wear items" or
"consumables" that will need to be
replaced during the life of the motor. The
frequency of required replacement is relat-
ed to how much the motor is used and how
hard it is pushed.
Replace both carbon brushes at the same
time when the motor no longer reaches full
power, or when the brushes measure less
than
1
⁄
4
" long (new brushes are
5
⁄
8
" long).
