SECTION 4: MAINTENANCE
Router Maintenance
Motor brushes will become loaded with
carbon deposits or wear out over time.
Extend the life of the motor brushes by
removing them periodically and cleaning
off the carbon deposits.
If the motor will not run, makes squealing
or grinding noises, or performance is dra-
matically decreased, check to see if the
motor brushes need to be replaced. When
replacing the motor brushes, replace both
at the same time.
To replace the motor brushes:
1. Remove the caps on the sides of the
motor housing as shown in Figure
22.
Replacing Brushes
Router maintenance is simple. Keep the
router free from dust, dirt and grease and
always store it in a dry place. Plastic parts
can easily be cleaned with a damp cloth,
but never use water to clean any electrical
parts. Solvents should also be avoided
on plastic because of the possibility of
damage.
Inspect the router for loose parts, dam-
aged cord or switch, and inspect the
bits for chips or cracks. Replace the bit
if it is worn or damaged. Continuous
use of a worn or damaged bit will not
only decrease working efficiency, but also
overload the motor, so the bit must be
frequently checked.
With the exception of the motor brushes,
the electrical components of this router
are not user serviceable.
Contact our Technical Support at (570)
546-9663 for any repair work that requires
opening the motor housing and for replace-
ment parts.
