Craftsman 315.279840 - Manual (Page 12)

OPERATION
Do not force. The weight of the unit supplies adequate
pressure. Let the sandpaper and sander do the work. Ap­
plying additional pressure sfows the motor, rapidly wears
sandpaper 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.
The front edge of the sander allows flush sanding in
corners. Always remove sander from workpiece before
turning the sander.
ORBITAL MOTION
See Figure 9.
Orbital motion is ideal for fast cutting action when remov­
ing old finishes, smoothing rough wood, cutting stock
down to required dimensions, or for finishing surfaces to
be painted. The sandpaper moves in tiny circles at a very
high speed, allowing the sander to move easily.
MAINTENANCE
▲
WARNING: When servicing, use only identicat
Craftsman replacement parts. Use of any other parts
may create a hazard or cause product damage.
WARNING: Aturays wear safety gaggles 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 sofvenCs 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.
A WARNING: Do not at any time let brake fluids,
gasoiine, petroleum-based products, penetrating
oils, etc., come in contact with plastic parts. Chemi­
cals can damage, weaken or destroy plastic which
may result In serious personal injury.
Electric tools used on fiberglass material, wallboard,
spackllng compounds, or plaster are subject to accel­
erated wear and possible premature failure because the
fiberglass chips and grindings are highly abrasive to bear­
ings, brushes, commutators, etc. Consequently, we do not
recommended usii^ 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 suffi­
cient 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.
