Carbon Brushes
Inspect all four brushes every 6 months or 250 hours.
Access to the brushes is gained through the front and
back motor vent plugs and under both motor covers (figure
6). Press tab on spring clip assembly in, rotate, then
remove (figure 7).Use needlenose pliers to disconnect the
shunt wire. If any brush has worn to 3/8" in length or
shorter, replace the entire set.
CAUTION:
Use only motor brush PN 40818A or
PN 40055A with shunt wire or motor
failure will occur.
When replacing the brushes make sure that the brush
seats against the commutator, the spring rest in the
recess of the brush, and the brush is free to travel. When
returning the switch cover, keep any wires clear of the
commutator and any pinch site.
