Motor Service

Keep the motor as clean as possible. Prevent any water, oil, or wood chips from penetrating inside the motor. Be sure to clean the machine after every use.

The bearings inside the motor are shielded and lubricated for the life of the bearing and require no routine maintenance.

This motor is equipped with long life carbon brush- es. However, brush life expectancy is affected by motor loading. Heavy motor loading will result in reduced brush life. Check brushes after every ten to fifteen hours of operation (Figure 51).

When the brushes are worn down to 1⁄4'' (6mm), it is time for replacement. When checking brushes, be sure to return each brush in the same position that it came from. When replacing old brushes, be sure to replace both brushes at the same time.
