Maintenance

DANGER: Never put lubricants
on the blade while it is spinning.
WARNING: To reduce the risk of
injury from unexpected starting
or electrical shock, unplug the
power cord before working on
the saw.
Replacing Carbon Brushes
The carbon brushes furnished will last
approximately 100 hours of running time or
20,000 on/off cycles. Replace both carbon
brushes when either has less than 1/4"
length of carbon remaining. To inspect or
replace brushes, first unplug the saw. Then
remove the black plastic cap on the side of
the motor (caution, this cap is spring
loaded by the brush assembly). Then pull
out the brush. Repeat for the other side. To
reassemble reverse the procedure. The
ears on the metal end of the brush assem-
bly 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. Otherwise a break-in
period will occur that will reduce motor

Lubrication

Ball Bearing Lubrication
All the motor bearings in this tool are
lubricated with a sufficient amount of high
grade lubricant for the life of the unit,
therefore, no further lubrication is
required.
Infrequent Lubrication as Required
1. Apply a light oil or a pressurized light
spray oil to the arm pivot shaft and
bevel pivot shaft.
2. Apply a light oil or a pressurized light
spray oil to the torsion spring as shown.
3. Apply a light oil or a pressurized light
spray oil to the lower guard spacer,
roller and cover plate as shown.
performance and increase brush wear.
Lower Blade Guard
Do not use the saw without the lower
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 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 build up with a damp cloth.
CAUTION: Do not use solvents on
the guard. They could make the plas-
tic "cloudy" and brittle.
WARNING: When cleaning lower
guard unplug the saw from the outlet
to avoid unexpected start-up.
Periodically, sawdust will accumulate
under the work table and base. This could
cause difficulty in the movement of the
work table when setting up a miter cut.
Frequently blow out or vacuum up the
sawdust.Check up stop, down stop and
bevel stops for sawdust accumulation,
which can affect capacity or accuracy.
WARNING: If blowing sawdust, wear
proper eye protection to keep debris
from blowing into eyes.
