G0689 13" Planer

Motor

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. Planing very wide, dense boards or cutting too deep will reduce brush life from overheating. Check brushes after every ten to fif- teen hours of operation or if motor loses power or becomes noisy (Figure 34).

Figure 34. Brush holder location (another brush is located on the other side of the motor from the one shown in this picture).

When the brushes are worn down to 14'' (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.
