DANGER
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. 30)
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 spring
loaded. 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.
CAUTION:
Do not use solvents on the guard. They could
make the plastic “cloudy” and brittle.
CAUTION!
When cleaning the lower guard, unplug the saw from the
power source receptacle to avoid unexpected startup.
SAWDUST
Periodically, sawdust will accumulate under the worktable
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 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 setscrews 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.
