Maintenance
Your 110 V Portable Planer will give you
hundreds of hours of operation time before
ever needing service. This product is dou-
ble insulated which provides protection
from electrical shock should a problem
ever develop with grounding. Great care
must be taken whenever servicing double
insulated equipment to make certain the
repair does not destroy the insulated prop-
erties. Service should be performed only
by a qualified electrical technician.

Brush Replacement
The universal motor has two brushes
which may periodically need replacement.
When checking or replacing the brushes,
make sure the slots the brushes fit into are
clear of grit or debris so the brushes are
free to move in and out.
To Replace The Brushes:
1. Remove the motor cover by remov-
ing the two screws on the housing.
2. Remove the brush caps with a large
flat bladed screwdriver. See Figure
10.
3. Pull the brush out. The end has a
metal disc which is attached to a
spring-like piece. If the slot has for-
eign material in it, the brush may be
hard to remove.
4. Clear the brush slot with a screw-
driver and make sure it is free of grit.
Insert the new brush, check to make
sure it goes into the slot and comes
out against the commutator.
5. Replace the brush cover.
6. Repeat for the other brush.
7. Replace the motor cover.
