Replacing Brushes - Grizzly T31634 Owner's Manual

Replacing Brushes

This miter saw is equipped with a universal motor
that uses two carbon brushes to transmit elec-
trical current inside the motor. These brushes
are considered to be regular "wear items" or
"consumables" that will need to be replaced dur-
ing the life of the motor. The frequency of required
replacement is often related to how much the
motor is used and how hard it is pushed.
Replace the carbon brushes (part number:
PT31634163 for T31634, or PT31635163 for
T31635) at the same time when the motor no lon-
ger reaches full power, or when the brushes mea-
