brushes are worn down to

⁄4'' (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.

V-Belt
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.
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 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
