Troubleshooting Guide - KNOVA KN CS-3555R Manual

MAINTENANCE
1. To inspect or replace brushes, first unplug the tool.
Remove the black plastic cap (1) on the side of the
motor (2).
NOTE: The brush assembly (3) has a spring, so the cap
(1) may pop out when loosened.
2. Pull out the brush assembly (3) and replace with the
new one, if needed. The ears on the metal end of the
assembly go in the same slots the carbon part fits into.
Tighten the cap snugly, but do not overtighten. Repeat
for the other side.
NOTE: To reinstall the same brushes, first make sure the
brushes go back in the way they came out. This will avoid a
break-in period that reduces motor performance and
increases wear.
