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 affected 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 14. When the

Figure 14. Brush holder location.

brushes are worn down to 14'' (6mm), it is time for replacement. 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 flat rubber V-belt located on the right side of the motor and cutter- head assembly (when facing the front of the machine). The belt is a durable long life belt, how- ever eventually it may require replacement:

1.Remove the depth-of-cut handle and the four Allen® head screws on the top cover. Pull the cover off and the sides are then free to be removed.

2.Remove the Belt Guard Cover. This piece just snaps into two grooves. Squeeze the top of the cover slightly and pull up to remove. See Figure 15.

3.''Roll off'' the old belt 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 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 slowly 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 pulley.

6.Replace the belt guard, sides, cover and handle.
