-20- G1017 12'' Portable Planer
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 14. When the brushes are
worn down to
1
⁄4'' (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.

V-Belt
The cutterhead is driven by a rubber V-belt locat-
ed on the left side of the motor and cutterhead
assembly. The feed rollers are driven by a chain
on the right side of the motor and cutterhead
assembly. To inspect or remove the V-belt:
1. Lower the cutterhead assembly and leave a
gap along the front edge of 1
1
⁄2'' to the table.
2. Remove the Belt Guard Cover.
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.
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. Do not use compressed air to remove
saw dust. Dust may be forced into normally pro-
tected parts which may cause damage to the
machine.
The bearings inside the motor are also shielded
and lubricated for the life of the bearing and
require no routine maintenance.
