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 also shielded and lubricated for the life of the bearing and require no routine maintenance.

This motor is equipped with long life carbon brushes. However, brush life expectancy is affect- ed by motor loading. Planing very wide, dense boards or cutting too deep will reduce brush life. Check brushes after every ten to fifteen hours of operation. See Figure 10. When the brushes are

Figure 10. Brush holder location (another brush is located on the other side of the motor from the one shown in this picture).

worn down to 14'' (6mm), it is time for replace- ment. When checking brushes, be sure to replace each brush in the same position and the same location that it came from. When replacing old brushes, be sure to replace both brushes at the same time.

The cutterhead is driven by a belt that is located on the right-hand side of the motor and cutter- head assembly (when facing the front of the machine). The belt is very durable, however eventually it may require replacement.

To replace the belt:

1.Remove the elevation handle and the 2 phillips head screws on the front and rear of the side cover. Pull the cover off.

2.Remove the Belt Guard shown in Figure 11 by removing the 2 phillps head screws that secure it.

3.Roll the old belt off, toward the side of the elevation screw.

4.Loop the new belt so that it completely sur- rounds the motor pulley but with only half of the "vees" engaged. Start the lower portion on the underside of the cutterhead pulley and slowly rotate the motor pulley with your free hand.

5.By pushing on the edge of the belt and slow- ly turning the pulleys by hand, you can force the belt over until all the “vees” of the belt are in alignment with the "vees" on the pulleys.

6.Replace the belt guard, side cover, and han- dle.
