WARNING:
Always wear safety goggles or safety
glasses with side shields during power tool operation
or when blowing dust. If operation is dusty, also
wear a dust mask.
GENERAL
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, carbon dust, etc.
_,
WARNING:
Do not at any time let brake fluids,
gasoline, petroleum-based
products, penetrating
oils, etc. come in contact with plastic parts.
Chemicals can damage, weaken or destroy plastic
which may result in serious personal injury.
It has been found that electric tools are subject to acceler-
ated wear and possible premature failure when they are
used on fiberglass boats, sports cars, wallboard, spack-
ling compounds,
or plaster. The chips and grindings from
these materials are highly abrasive to electric tool parts
such as bearings, brushes, commutators,
etc. Conse-
quently, it is not recommended
that this tool be used for
extended work on any fiberglass material, wallboard,
spackling compounds,
or plaster. During any use on these
materials it is extremely important that the tool is cleaned
frequently by blowing with an air jet.
LUBRICATION
All of the bearings in this tool are lubricated with a suffi-
cient amount of high grade lubricant for the life of the unit
under normal operating conditions. Therefore, no further
lubrication is required.

WARNING:
To
and
all
ensure safety
reliability,
repairs -- with the exception of the externally
accessible brushes -- should be performed by a
qualified service technician at a Sears store to avoid
risk of personal injury.
