Motor brushes are a consumable item
inside the motor and will require replace-
ment with time. Heavy workloads and
excessive pressure on sanding head can
quickly wear motor brushes.
Motor brushes may require replacement if
motor becomes sluggish, is very slow to
start, or generates a grinding sound within
the housing.
IMPORTANT: Always replace motor
brushes as a pair to ensure even wear.

Each sanding head connects to the
motor using a metal gear sprocket (see
Figure 20) with a plastic gear cap. Over
time, the gear cap may become worn,
resulting in loss of power transfer to the
sanding head. Additional gear caps are
provided on the triangular sanding head
(see
Figure 20).
To replace the gear cap, carefully remove
the worn gear cap with a pair of pliers,
and place a new cap over the metal gear
sprocket.
