Operation - Craftsman 315.215700 Owner's Manual

APPLICATIONS
(Use only for the purposes listed below)
• Sanding on wood surfaces.
• Sanding plastics.
,_l WARNING: Do not use this sander for sanding
metals. Sanding metals will cause sparks that
will ignite wood and dust particles on sander, in
the dust collector, or in workshop.
SANDING SLEEVE SELECTION
Selecting the correct size diameter, correct size grit,
and correct type sanding Sleeve is an extremely
important step in achieving a high quality sanded
finish. Aluminum oxide, silicon carbide, and other
synthetic abrasives are best for power sanding.
Natural abrasives, such as flint and garnet are too soft
for economical use in power sanding.
In general, coarse grit will remove the most material
and finer grit will produce the best finish in all sanding
operations. The condition of the surface to be sanded
will determine which grit will do the job. If the surface
is rough, start with a coarse grit and sand until the
surface is uniform. Medium grit may then be used to
remove scratches left by the coarser grit and finer grit
used for finishing of the surface. Always continue
sanding with each grit until surface is uniform.
Note: Oo not use sander without a sanding sleeve,
Doing so will damage the rubber spindle.
Select and install the desired sanding sleeve for your
particular application. As mentioned previously,
sanding sleeves from 1/2 in. to 3 in. can be used with
this sander. Choose one that is close in size to the
workpiece you are sanding. Also install the
appropriate throat plate, with the least amount of
clearance for the sanding sleeve you choose.
_k WARNING: Failure to use the correct size
throat plate with its matching sanding sleeve
could result in fingers being pinched or the
workpiece being pulled down between the throat
plate and sanding sleeve.
PREPARING FOR OPERATION
See Figure 8.
When preparing for operation we recommend that
your sander be secured in a permanent location such
as to a workbench.
If sander is to be used in a portable application, we
recommend that you fasten it permanently to a
mounting board that can easily be clamped to a
workbench or other supporting surface. See Figure 8.
The mounting board should be of sufficientsize to avoid
tipping of sander while in use. Any good grade plywood
or chipboard with a 3/4 in. thickness is recommended.

Mount sander to board using holes in cabinet as a
template for hole pattern. A 1/4 in. hole is located on
each of the four corners of the cabinet. Use 1/4 in.
bolts for securing sander to a workbench or mounting
board. If lag bolts are used, make sure they are long
enough to go through holes in sander, holes in
cushions and material sander is being mounted to. If
machine bolts are being used, make sure bolts are
long enough to go through holes in sander cabinet,
holes in cushions, material being mounted to, lock
washers, and hex nuts.
Note: It may be necessary to countersink hex nuts
and washers on bottom side of mounting board.
The supporting surface where sander is mounted
should be examined carefully after mounting to make
sure that no movement during use can result. If any
"tipping" or "walking" is noticed, secure workbench
legs or supporting surface before beginning sanding
operations. Support workpiece with miter gage,
backstop or worktable. A worktable should be a stable
support. A backstop is a support for the workpiece.
When preparing for operation, make sure hex nut on
top of spindle is tightened securely. Also make sure
that wrench has been removed from hex nut and
returned to wrench storage area.
_k WARNING: Do not wear loose clothing or
jewelry when operating sander. They could get
caught in moving parts, causing serios injury.
Keep head away from sander and sanding area.
Hair could get caught in the rotating parts,
causing serious personal injury,
