the carbon part fits into. 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 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.
Develop a regular check to make sure
the lower guard is working properly.
Clean the lower guard of any dust or
buildup with a damp cloth.
● When cleaning the lower guard,
unplug the saw from the power
source receptacle to avoid
unexpected startup.
● Do not use solvents on the guard.
They could make the plastic
“cloudy” and brittle.
MAINTENANCE
To avoid injury, never put lubricants
on the blade while it is spinning.
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 in the parts list.
Reassemble exactly as the original
assembly to avoid electrical shock.
REPLACING CARBON BRUSHES
(FIG. WW)
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).
Remove the cap cautiously, because
it is springloaded. 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
