MAINTENANCE
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 identifi
ed
in the parts list. Reassemble
exactly as the original assembly
to avoid electrical shock.
REPLACING CARBON BRUSHES
(FIG. NN)
The carbon brushe (3) that are
provided will last approximately 50
hours of running time, or 10,000 ON/
OFF cycles. Replace carbon brushe
(3) when it 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 black plastic
cap (1) on the side of the motor (2).
Remove the cap carefully, because it is
spring-loaded. Then pull out the brush
and replace.
To reassemble, reverse the procedure.
The ears on the metal end of the
assembly go in the same hole in which
WARNING
!
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.

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. Before each use, with
the saw unplugged, check to make
sure the lower guard moves smoothly
when the cutting head is raised and
lowered. If needed, clean any sawdust
buildup with a damp cloth. Check to
see if any of the link or pivot points
need lubrication. If so, see lubrication
instructions on page 41.
CAUTION: Do not use solvents on the
guard. They could make the plastic
“cloudy” and brittle.
