MAINTENANCE
WARNING
:
When servicing, use only identical
Craftsman replacement parts. Use of any other parts
may create a hazard or cause product damage.
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 MAINTENANCE
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, dust, oil, grease, 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.
Electric tools used on fiberglass material, wallboard,
spackling compounds, or plaster are subject to
accelerated wear and possible premature failure because
the fiberglass chips and grindings are highly abrasive to
bearings, brushes, commutators, etc. Consequently, we
do not recommended using this tool for extended work on
these types of materials. However, if you do work with any
of these materials, it is extremely important to clean the
tool using compressed air.
LUBRICATION
All of the bearings in this tool are lubricated with a
sufficient amount of high grade lubricant for the life of
the unit under normal operating conditions. Therefore, no
further lubrication is required.
Only the parts shown on the parts list are intended to be
repaired or replaced by the customer. All other parts
should be replaced at a Sears Service Center.
CHUCK REMOVAL

The chuck can be removed and replaced with a new one.
