screw by turning it clockwise.
Remove the wrench, and store
it in a safe place.

freely.
REPLACING CARbON bRUSHES
(fIG. 33-34)
FIG. 33
FIG. 34
The factory installed carbon brushes in the
motor assembly. Inspect them regularly
by following the instructions below. Keep
brushes clean and sliding freely in their
guides. Always replace a used brush in the
same orientation in the holder as it was prior
to its removal.
1. First unplug the saw before inspecting
or replacing brushes.
2. Replace both carbon brushes when
either has less than 1/4” (6 mm) of
carbon remaining, or if the spring or
wire is damaged or burned.
3. Use a slotted screwdriver, to remove
the black plastic cap on each side of
the motor housing (Fig. 33), and carefully
withdraw the spring-loaded brush
assemblies. Keep brushes clean and
sliding freely in their guide channels.
NOTICE: To reinstall the same brushes,
make sure the brushes go back in the
same way they came out. This will avoid a
break-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 (Fig. 34).
5. Remember to replace both end caps
after inspecting or servicing brushes.
Tighten the caps snugly, but do not
over-tighten. The saw should be allowed
to “RUN IN” (run at no-load without a
blade) for 5 minutes before use to seat
the new brushes properly.
