DANGER
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. DD)
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” 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 increase 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.
AUTION: Do not use solvents on the guard. They
could make the plastic “cloudy” and brittle.
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.
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 lubrication is required.
Lubrication the Following as Required:
Chop pivot
: light machine oil or aerosol will penetrate
from the ends of the junction points. A qualified
service technician can remove the pivot upstop to
relieve tension, and the 2 metric set screws holding
the shaft, in order to drive the shaft about 3/4” right.
Exposed surfaces are lubricated with automotive type
oil.
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.
