MAINTENANCE
To avoid injury, never put lubricants
on the blade while it is spinning.
WARNING
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.
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. MM)
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). Remove the cap cautiously,
because it is springloaded. 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
: 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.
WARNING
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.
SAWDUST
Periodically, sawdust will accumulate
under the work table and base. This
could cause difficulty in the movement of
the worktable when setting up a miter cut.
