● To avoid fire or toxic reaction,
never use gasoline, naphtha
acetone, lacquer thinner or
similar highly volatile solvents to
clean the miter saw.
● To avoid injury from unexpected
starting or electrical shock,
unplug the power cord before
working on the saw.
● For your safety, this saw is double
insulated. To avoid electrical
shock, fire or injury, use only
parts identical to those identified

REPLACING CARBON BRUSHES
(FIG. RR)
The carbon brushes furnished 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. length of
carbon remaining, or if the spring or
wire is damaged or burned. To inspect
or replace brushes, first unplug the
saw. Then remove the black plastic
cap (1) on the side of the motor (2).
Carefully remove the spring-loaded
cap. Then pull out the brush (3) and

replace. Replace for the other side. To
reassemble, reverse the procedure.
The ears on the metal end of the
assembly go in the same hole the
carbon part fits into. Tighten the cap
snugly, but do not overtighten.
NOTE: When reinstalling the same
brushes, put them back in the way they
came out. This will avoid a break-in
period that reduces motor performance
and increases wear.

LOWER BLADE GUARD
Do not use the saw without the lower
blade guard. The lower blade guard is
attached to the saw for your protection.
Should the lower guard become
damaged, do not use the saw until the
damaged guard has been replaced.
Check regularly to make sure the lower
guard is working properly. Clean the
lower guard of any dust or buildup with
a damp cloth.
