Maintenance Instructions

WARNING
Always be sure that the tool is switched OFF and
unplugged before changing blade or servicing saw.
Keep the tool cleaned. Remove accumulated dust from
working parts.
Make sure that the tool operates properly.
Periodically check screws and bolts for tightness.

Replacing Carbon Brushes

The carbon brushes furnished will last approximately 50
hours of running time or 10,000 ON/OFF cycles. Replace
both carbon brushes when either has less than
of carbon remaining.
1. To inspect or replace brushes, first unplug the
machine. Then remove the black plastic cap on the
side of the motor.
CAUTION This cap spring-loaded by the brush as-
sembly.
Then pull out the brush. Repeat for the other side.
2. To reassemble reverse the procedure. The ears on
the metal end of the brush assembly go in the same
hole the carbon part fits into. Tighten the cap snugly
but do not overtighten.
NOTE! To reinstall the same brushes, first make sure
the brushes go back in the way they came out.
Otherwise, a break-in period will occur that will
reduce motor performance and increased brush
wear.

Lubrication

Use light household oil (sewing machine oil) on metal-to-

debris will cling and a fire hazard from sparks could be
caused.
