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

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.
CAUTION: Do not use solvents on the guard. They
could make the plastic "cloudy" and brittle.
I,a, W ARNING I
When cleaning the lower guard, unplug the saw from
the power source receptacle to avoid unexpected
startup.
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.
la,WARNING I
If blowing sawdust, wear proper eye protection to
keep debris from blowing into eyes.
LUBRICATION
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 bearing 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.
