10.2 Lower Blade Guard
Do not use saw without lower blade guard. The
lower blade guard is attached to the saw for your
protection. Should the lower guard become
damaged, do not use 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 lower guard,
unplug saw from power source receptacle to
avoid unexpected startup.
Do not use solvents on lower
blade guard; they could make the plastic
“cloudy” and brittle.
10.3 Lubrication
All 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. Use a light
household oil, such as sewing machine oil. Avoid
excessive oil, to which saw dust will cling.

Chop pivot and spring.

Central pivot of plastic guard: Use light machine
oil on metal-to-metal or metal-to-plastic guard
contact areas as required for smooth, quiet
operation.

Table extension rods.
10.4 Commutator brush inspection
To maintain motor efficiency, inspect the two carbon
brushes every two months, or more frequently if saw
is heavily used. Stalling or loss of power may be a
symptom of worn carbon brushes. If one brush is
worn out, replace both at the same time.
Continued use of damaged or
worn brushes may result in damage to motor
armature.
1. Unplug saw from power source.
2. Unscrew and remove cap with a flat blade
screwdriver. See Figure 10-1. Note: Unscrew
cap cautiously – the brush spring will push it out.
3. Pull out brush assembly. Notice orientation of
brush as you remove it; it should be inserted in
the same manner; curvature of brush will match
curvature of motor. (This will avoid a break-in
period that reduces motor performance and
increases wear.)
4. Inspect brush; it should be replaced if any of the
following are discovered:

Brush has worn to about 1/4-inch long.

Signs of crumbling, burning or breaking.

End of brush is rough or pitted.

Abnormal coloration of spring

Broken lead in spring

Collapsed spring
5. Install new brush (or reinstall current brush) and
gently press it all the way into hole.
6. Install cap snugly, but do not overtighten.
7. Repeat for other brush.
