Maintenance
To avoid injury while
performing maintenance, always unplug the
power cord before working on the saw.
Failure to comply may cause serious injury!
Never use gasoline or any
highly volatile solvents to clean the miter
saw. Failure to comply may cause serious
injury!
Use only replacement parts
that are identical to the parts list at the end
of this manual and reassemble exactly as the
original assembly to avoid electrical shock.
Failure to comply may cause serious injury!
Replacing Carbon Brushes
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:
1. Unplug the saw.
2. Remove the black plastic cap on the side of
the motor
Remove the cap cautiously, because it is spring-
loaded.
3. Pull out the brush and replace.
4. Reverse above steps to reassemble.
Tighten the cap snugly, but do not over-
tighten.
Replace the brush for the other side in the same
manner described above.
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.
When cleaning the lower
guard, unplug the saw from the power
source receptacle to avoid unexpected
startup.
Do not use solvents on the
guard. They could make the plastic “cloudy” and
brittle.
Saw Dust
Periodically, saw dust 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 saw dust.
If blowing saw dust, wear
proper eye protection to keep debris from
entering 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.
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 saw dust will cling.
