Replacement Of Carbon Brushes; Lubrication - Craftsman 320.27683 Operator's Manual

REPLACEMENT OF CARBON BRUSHES (Fig .29)
Replacement brush sets are
Fig. 29
available through Sears Parts
and Repair Centers.
1. Unplug the router motor
before inspecting or
replacing brushes.
2. 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.
3. Using a slotted screwdriver,
remove the black, plastic
cap on each side of
the router motor (Fig. 29) and carefully withdraw the spring-loaded brush
assemblies. Keep brushes clean and sliding 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 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. 29).
5. Remember to replace both end caps after inspecting or servicing brushes.
Tighten the caps snugly, but do not over-tighten. The router should be
allowed to "run in" (run at no load without a cutter bit) for 5 minutes before
use, to seat the new brushes properly.
A_, WARNING: For your safety, always turn off the switch and unplug the router
motor from the power source before performing any maintenance or cleaning.
LUBRICATION
All of the bearings in this tool are lubricated with a sufficient amount of high-
grade lubricant for the life of the tool under normal operating conditions.
Therefore, no further lubrication is required.
