MAINTENANCE
Before cleaning or performing any maintenance, verify that
the router has been disconnected from the power supply. Keep
all ventilation openings clean. Avoid using solvents when
cleaning plastic parts. Most plastics are susceptible to damage
from various types of commercial solvents. Use a clean cloth to
remove dirt, oil, and grease.
If the supply cord is damaged, it must be replaced by a specially
prepared cord available through the service organization.
WARNING
Do not let brake fluids, gasoline,
petroleum-based products, penetrating oil, etc. come
into contact with plastic parts. They contain chemicals
that can damage, weaken, or destroy plastic.
WARNING
To ensure safety and reliability, all repairs
should be performed by a qualified service technician.
REPLACEMENT OF CARBON BRUSHES (FIG. 23)
1. Disconnect the plug from the power supply.
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. 23) 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 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. 23).

5. Remember to replace both end caps after inspecting or
servicing brushes. Tighten the caps snugly, but do not
overtighten. 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.
WARNING
For your safety, always turn off the switch
and unplug the router motor from the power source
before performing any maintenance or cleaning.
Plug the detachable cord into the power source.
Pull the switch to "ON" position.
Remove the brush caps, and replace the old brushes
with new ones.
Change to a sharp bit.
Select an appropriate bit speed.
Use only 1/4" diameter bits with the 1/4" collet; use
only 1/2" diameter bits with the 1/2" collet.
