Craftsman 315.279870 Sander User Manual


 
Do not force. The weight of the unit supplies ad-
equate pressure, so let the sanding disc and sander
do the work. Applying additional pressure only slows
the motor, rapidly wears sanding disc and greatly
reduces sander speed. Excessive pressure will
overload the motor causing possible damage from
motor overheating and can result in inferior work. Any
finish or resin on wood may soften from the frictional
heat. Do not allow sanding on one spot too long as
the sander's rapid action may remove too much
material, making the surface uneven.
Extended periods of sanding may tend to overheat the
motor. If this occurs, turn sander off and wait until
sanding disc comes to a complete stop, then remove
it from workpiece. Remove your hand from vent area,
remove sanding disc, then with your hand removed
from vent area, turn sander on and run it free without
a load to cool motor.
Flush sanding can be performed with your sander.
See Figure 11. The front edge of your sander allows
flush sanding. Upon completion of sanding operation,
turn sander off and wait until sanding disc comes to a
complete stop before removing from workpiece.

WARNING: Collected sanding dust from
sanding surface coatings such as polyurethanes,
linseed oil, etc. can self-ignite in your sander
dust bag or elsewhere and cause fire. To reduce
the risk of fire always empty your dust bag
frequently (10-15 minutes) while sanding and
never store or leave a sander without totally
emptying its dust bag. Also follow the
recommendations of the coatings manufacturers.
,_ WARNING: When servicing use only identical Craftsman replacement parts. Use of any other parts may
create a hazard or cause product damage.
GENERAL
Only the parts shown on parts list, page 15, are
intended to be repaired or replaced by the customer.
All other parts represent an important part of the
double insulation system and should be serviced only
at a Sears Service Center.
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 boats, sports cars,
wallboard, spackling compounds, or plaster. The
chips and grindings from these materials are highly
abrasive to electric toot 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.
_ 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.
