•
Periodically, saw dust will accumulate under saw
table and base. This could cause difficulty in the
movement of the table when setting up a miter cut.
Frequently blow out or vacuum up the saw dust.
Turn saw over and blow out dust from beneath
saw table.
•
Wipe dust/debris off the slide bars.
•
Clean out the fence extension trackways.
•
Remove table inserts to clear away any small
pieces beneath. Reinstall table inserts before
operating.
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.
