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 easily 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.
