a. Inner filter bag
4. Only when necessary
- Low Power/Sparks - Commutator Polish
a. It is not necessary to polish all commutators. Commutators in
pictures 1 & 2 have a gray film. This is graphite from the brushes
and desirable since it acts as a lubricant. Picture 3 shows heat and
4 uneven wear. These two should be polished.

b. Hazardous conditions will exist during this step:
i. Wear safety glasses, remove jewelry from hands, wrists and
neck (if dangling). Secure loose clothing and long hair.
c. Another way to determine if polishing is necessary is to observe the
arcing characteristics of the function while in operation.
d. Maximum Acceptable Arc – Continuous no greater than 1/16”
i.
e. Commutators producing more than the maximum acceptable arc
should be polished. Brushes may have to be changed.
f. Hazardous conditions will exist during this step:
i. Exposure to spinning components: brushroll, motor, belt,
fan and exhaust debris.
ii. Wear safety glasses and remove jewelry from hands, wrists
and neck (if dangling). Secure loose clothing and long hair.
iii. Exposure to lethal amperage: Keep hands away from
terminals, wires and motor components
g. Lightly touch the commutator with the commutator cleaner.
Burnishing will happen quickly.
i.
h. Turn the commutator cleaner over and do the same for the belt
drive shaft.
