MAINTENCE
WARNING! For your safety, remove the plug from power
source outlet before adjusting, maintaining, of lubricating
your belt and disc sander.
WARNING! To avoid electrocution or fire, any repairs to
electrical system should be done only by qualified service
technicians. Unit must be reassembled exactly to factory specifi-
cations.
If power cord is worn or cut, or damaged in any way, have it repai-
red immediately. Frequently blow out or vacuum out any dust that
may accumulate inside the motor. A coat of automobile-type wax
applied to the worktable will make it easier to feed the work while
finishing. Do not apply wax to the abrasive belt table because the
belt could pick up the wax and deposit it on the pulleys, cause the
belt to slip.

the factory. They require no further lubrication.
