Maintenance - Craftsman 315.212400 Owner's Manual

WARNING:
When servicing, use only identical
Craftsman replacement parts. Use of any other
part may create a hazard or cause product
damage.
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. They
contain chemicals that can damage, weaken or
destroy plastic.
It has been found that electric tools are subject to
accelerated wear and possible premature failure when
they are used on fiberglass, wallboard, spackling
compounds, or plaster. The chips and grindings from
these materials are highly abrasive to electric tool
parts such as bearings, brushes, commutators, etc.
Consequently, 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
sufficient amount of high grade lubricant for the life of
the unit under normal operating conditions. Therefore,
no further lubrication is required.

MAINTENANCE

EXTENSION CORDS
The use of any extension cord will cause some loss of
power. To keep the loss to a minimum and to prevent
tool overheating, use an extension cord that is heavy
enough to carry the current the tool will draw.
A wire gage size (A.W.G.) of at least 14 is recom-
mended for an extension cord 25 feet or less in
length. When working outdoors, use an extension
cord that is suitable for outdoor use. The cord's jacket
will be marked WA.
CAUTION:
cutting area and position the cord so that it will
not get caught on lumber, tools, etc., during
cutting operation.
WARNING:
use. If damaged, replace immediately. Never use
tool with a damaged cord since touching the
damaged area could cause electrical shock
resulting in serious injury.
WARNING:
safety glasses with side shields during power
tool operation or when blowing dust. If operation
is dusty, also wear a dust mask.
