MAINTENANCE
Never put lubricants on the blade
while it is spinning.
● To avoid fi re 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, fi re or injury, use only
parts identical to those identifi ed
in the parts list. Reassemble
exactly as the original assembly
to avoid electrical shock.
REPLACING CARBON BRUSHES
(FIG. JJ)
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, fi rst 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 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 fi ts 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.
Fig. JJ
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.
● Do not use solvents on the guard.
They could make the plastic
“cloudy” and brittle.
● When cleaning the lower guard,
unplug the saw from the power
source receptacle to avoid
unexpected start-up.
