MAINTENANCE
WARNING
For your own safety, turn the switch off
and remove the plug from the power source outlet
before maintaining or lubricating your miter saw.
GENERAL MAINTENANCE
Occasionally use a cloth to wipe off chips and dust from the
machine. And oil the rotary parts once a month to extend the
tool life. Do not oil the motor.
BRUSHE INSPECTION (FIG. 47)
WARNING
Always disconnect the plug from the
power source before inspecting the brushes.
The carbon brushes that are provided will last approximately
50 hours of running time, or 10,000 ON/OFF cycles. Replace
both carbon brushes when either has less than 1/4 in. of
carbon remaining, or if the spring or wire is damaged or
burned.
To inspect or replace brushes, first unplug the saw, and then
remove the motor cover (1) by loosening two screws (2).
Remove the black plastic cap (3) on the side of the motor.
Remove the cap carefully, because it is springloaded. Then
pull out the brush (4) and replace.
Replace the other side in the same manner. To reassemble,
reverse the procedure. The ears on the metal end of the
assembly go in the same hole in which the carbon part fits.
Tighten the cap snugly, but do not overtighten.

NOTE:
To reinstall the
same brushes,
first make sure
the brushes go
back in the way
they came out.
This will avoid a
break-in period.
