components should be done by qualified service
technicians.
Before each use check for damaged, missing, or worn
parts; check for alignment of moving parts, binding,
improper mounting, or any other conditions that may
affect the operation. Should any oFthese conditions exist,
do not use the sander until properly repaired or parts are
replaced. Frequently blow or vacuum dust from alf sander
parts and motor housing.
After sanding wood or non-metallic material, always clean
the sawdust from sander or work area before grinding or
sharpening metal workpieces. Sparks could ignite and
cause a fire.

require no further lubrication. Use a spray lubricant to
