Maintenance and Lubrication

Maintenance

DANGER: Never put lubricants on the blade while it
is spinning.
WARNING: To reduce the risk of injury from unex-
pected 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
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. Otherwise a
break-in period will occur that will reduce motor perfor-
mance and increase brush wear.

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 under normal operating conditions, therefore, no fur-
ther lubrication is required (see below).
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.
4. Use a small amount of general purpose grease on the
miter index indents that are located below the miter
scale on the front of the unit. See Illustration.

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 plastic "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 move-
ment of the work table when setting up a miter cut. Fre-
quently blow out or vacuum up the sawdust.Check up
stop, down stop and bevel stops for sawdust accumula-
tion, which can affect capacity or accuracy.
WARNING: If blowing sawdust, wear proper eye
protection to keep debris from blowing into eyes.
