source before performing any maintenance or
cleaning.
1. Unplug the saw before inspecting or replac-
ing brushes.
2. Replace both carbon brushes when either
has less than 1/4-in. length of carbon remain-
ing, or if the spring or wire is damaged or
burned.
3. Using a slotted screwdriver, remove the
black, plastic cap on each side of the motor,
and carefully withdraw the spring-loaded
brush assemblies. Keep brushes clean and slid-
ing freely in their guide channels.
NOTE: To reinstall the same brushes, make sure
that the brushes go back in the same way they
came out. This will avoid the need for a "run-
in" period.
4. Insert new brush assemblies into the guide
channels with the carbon part going in first,
being certain to fit the two metal "ears" into
their slots in the channel.
5. Remember to replace both end caps after in-
specting or servicing brushes. Tighten the caps
snugly, but do not over-tighten. Before use,
the saw should be allowed to "RUN IN" (run at
no load without a blade) for 5 minutes to seat
the new brushes properly.
CHANGING THE BLADE
WARNING: Be sure to wear protective work
gloves while handling a saw blade. The blade
can injure unprotected hands.
1. Unplug the saw from the power source.
WARNING: To prevent personal injury, AL-
WAYS disconnect the plug from power source
BEFORE assembling parts, making adjustments
or changing blades.
2. Place the saw, on its side, on a flat surface.
3. Loosen the depth-of-cut adjustment lever,
raise the saw up all the way, and tighten the
lever. This gives you easier access to the blade
mounting area.
4. Place the saw upright on its base on a flat
surface.
5. To loosen the spindle-clamping screw "A,"
depress the spindle-lock button. Insert the
blade wrench in the spindle clamping screw
"A." Move the wrench in and out slightly until
you feel the spindle lock button depress fur-
ther, which locks the blade in position so the
spindle clamping screw can be removed.

6. Keeping the spindle lock button firmly de-
pressed, turn the wrench clockwise to remove
the spindleclamping screw.
7. Use the blade-guard lever to raise the lower
blade guard and hold it in the raised position
for the next steps.
8. Completely remove the spindle-clamping
screw "A," the outer "D" washer, and the
blade.
9. The remaining washer is the inner bushing
washer that fits around the spindle shaft; it
does not need to be removed.
10. Put a drop of oil onto the inner bushing
washer and outer "D" washer where they will
touch the blade.
11. Place the new saw blade inside the low-
er blade guard, onto the spindle shaft, and
against the inner bushing.
NOTE: The teeth of the blade should point
upward at the front of the saw. The printed
side will face outward when using the blade
included with the saw.
12. Replace the "D" washer.
13. Firmly hold down the spindle lock button
as you replace the spindle screw and hand
tighten it in a counterclockwise direction. Then
use the blade wrench to securely tighten the
spindle clamping screw.
