CAUTION
To avoid injury, never put lubricants on the
blade while it is spinning.
CAUTION
To avoid fire or toxic reaction, never use
gasoline, naphtha acetone, lacquer thinner or
similar highly volatile solvents to clean the
miter saw.
CAUTION
To avoid injury from unexpected starting
or electrical shock, unplug the power cord
before working on the saw.
CAUTION
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. 45)
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 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.

working properly. Clean the lower guard of any
dust or buildup with a damp cloth.
CAUTION
® 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 britUe.
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. Frequently blow out or vacuum up
the sawdust.
CAUTION
If blowing sawdust, wear proper eye
protection to keep debris from entering eyes.
LUBRICATION (FIG. 46)
All the motor bearings in this tool are lubricated
with a sufficient amount of high grade lubricant
for the life of the unit under normal operating
conditions; therefore, no further lubrication is
required.
Lubricate the Following as necessary:
Chop pivot: Apply light machine oil to points
indicated in illustration.
Central pivot of plastic guard: Use light
household oil (sewing machine oil ) on metal-
to-metal or metal-to-plastic guard contact areas
as required for smooth, quiet operation. Avoid
excessive oil, to which sawdust will cling.
Link: (which actuates the lower guard
movement) may be oiled at the rear pivot,
greased at ball bearing contact, and oiled where
the link actuates the acetyl roller of the lower
guard, if the down chop motion is hard to start.

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
