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 (
