"OFF" position.
2. Be sure the guard assembly is securely attached to the spindle
housing.

MAINTENANCE OF TOOL
CLEANING
Blowing dust and grit out of the motor housing using compressed air is
a necessary regular maintenance procedure. Dust and grit containing
particles from metal grinding often accumulate on interior surfaces and
could create an electrical shock hazard if not frequently cleaned out.
CAUTION: Never use solvents or other harsh chemicals for cleaning
the non-metallic parts of the tool. Use clean, dry rag only.
LUBRICATION
Sears tools are properly lubricated at the factory and are ready for use.
Tools should be relubricated regularly every sixty days to six months,
depending on usage. (Tools used constantly on production or heavy-
duty jobs and tools exposed to heat may require more frequent
lubrication.) This lubrication should only be attempted by trained power
tool repairpresons such as those at Sears Service Centers or in other
qualified service organizations.
