INTRODUCTION
GENERAL
Your Craftsman 3-Inch Belt Sander is suitable for
coarse, medium and fine sanding of wood, metals,
plastics and other materials. It is ideal when used for
smoothing
rough boards, chamfering,
rounding
edges and many other general sanding applications.
Its balanced design makes it easy to use. All 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.
DOUBLE INSULATION
Double insulation is a concept in safety, in electric
power tools, which eliminates the need for the usual
three wire grounded power cord and grounded supply system. Wherever there is electric current in the
tool there are two complete sets of insulation to protect the user. All exposed metal parts are isolated
from the internal metal motor components with protecting insulation.
RULES FOR SAFE OPERATION
READ ALL INSTRUCTIONS
--
IMPORTANT -- Servicing of a tool with double insulation requires extreme care and knowledge of the
system and should be performed only by a qualified
service technician.
For service, return the tool to
your nearest Sears store for repair which will be
done with original factory replacement parts. WARNING: KEEP HANDS AND FINGERS AWAY FROM

JOBS WHERE THE SANDER MAY NEED TO BE
STOPPED SUDDENLY.
PREPARING FOR OPERATION
Fig. 1
For ease of operation your Sander has a front handle
and a rear handle. These handles allow two-hand
operation
which aids in maintaining
control
and
keeping sanding area level with workpiece.
When
operating
your Sander hold the front handle with
your left hand and the rear handle with your right
hand as shown in Fig. 2.
WARNING: KEEP HANDS AND FINGERS CLEAR OF

OVER THE FRONT OR RIGHT EDGE OF THE
SANDER AS SHOWN IN FIG. 3. IF THE SANDING
BELT WERE TO RUN OFF, OR IF IT WERE NOT PROPERLY ADJUSTED, YOUR FINGERS COULD COME
IN CONTACT WITH THE MOVING SANDING BELT
RESULTING
IN POSSIBLE
SERIOUS
INJURY.
Always operate your Sander in the correct position
as shown in Fig. 2.
CORRECT
Fig. 2
Selecting the correct size and type sanding belt is an
important step in achieving a high quality sanded
finish. Standard 3 inch x 21 inch sanding belts made
of aluminum oxide, silicone carbide, and other synthetic abrasives
are best for power sanding.
In
general, coarse grit will remove the most material
and finer grit will produce best finish in all sanding
operations. The condition of the surface to be sanded will determine which grit belt will do the job. If the
surface is rough, start with a coarse grit belt sanding
until surface is uniform. Medium grit belt may then
be used to remove scratches left by the coarser belt
and finer grit belt used for finishing of the surface.
Always continue
sanding with each grit belt until
surface is uniform.

SANDING
BELT
FROM POWER SUPPLY.
To release the sanding belt, push the front pulley
squarely against the top of workbench as shown in
figure 4. When sufficient
pressure is exerted, the
spring will be compressed
allowing the pulley to
lock in a rear position. This frees the sanding belt so
it can be removed. Install new belt making sure arrow inside of belt is pointing in the direction of rotation, which is clockwise when looking into open side
of sander. See Fig. 5. Roughly align the belt to its
correct position. Then place sander into position
shown in figure 6. Insert a screwdriver
into slot on
idler pulley yoke and apply backward pressure. The
pulley will snap back into operating position.
Fig. 4
Fig. 5
To adjust sanding belt, connect Sander to power
supply. Place Sander in upside down position as illustrated. See Fig. 7. NOTE: This position is for adjustments
only. The Sander is not in an operating
position. Pull switch trigger and release immediately. Observe tracking of sanding belt. If the sanding
belt runs inward, turn the tracking screw clockwise.
If the sanding belt runs outward, turn the tracking
screw counterclockwise.
This should be done until
you are sure belt will not run off sander, or come in
contact with internal parts. After installing
a new
sanding belt, it may become necessary to change
the adjustment
several times until the belt becomes
pliable.
WARNING: IF SANDING BELT BEGINS TO WEAR
EXCESSIVELY ON THE INNER EDGE, RE-ADJUST
TRACKING SCREW. IT IS ADJUSTED TOO FAR IN.
WARD AND THE SANDING
BELT IS RUBBING
AGAINST INTERNAL PARTS. When you are sure the
belt will not rub against internal parts, start the
Sander and fine adjust the tracking screw until the
belt stabilizes.

When correctly adjusted, the outer edge of the belt
will be even with the outer edge of the base of the
Sander. Belt life will be greatly increased if a few
seconds are spent adjusting the belt tracking.

OPERATION
TO OPERATE
Clamp or otherwise secure the work to prevent it
from
moving
under the Sander.
WARNING:
UNSECURED WORK COULD BE THROWN BACK
TOWARD OPERATOR CAUSING INJURY. Before
placing Sander on work surface, press the trigger
switch and let the motor reach its maximum speed,
then lower the Sander to the work surface with a
slight forward motion. Using the rear handle to control the Sander and the front handle only to guide it,
move it slowly over the work. See Fig. 8. Allowing the
Sander to remain in one place will result in an
uneven surface. WARNING: KEEP A FIRM GRIP ON
SANDER WITH BOTH HANDS AT ALL TIMES.
FAILURE TO DO SO COULD RESULT IN LOSS OF
CONTROL LEADING TO POSSIBLE SERIOUS INJURY. The Sander was designed to provide the proper weight on the sanding belt and extra pressure
will only result in uneven work, clogged belts, and
possible motor burnout.
Use a coarse belt when heavy cutting is desired, not
heavy pressure. The importance of this cannot be
over-emphasized, the weight has been built into the
tool to give the most efficient pressure at the proper
location.

Only the parts shown on parts list, page eleven, 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 by a qualified service technician.
Avoid using solvents when cleaning plastic parts.
Most plastics are susceptible to various types of
commercial solvents and may be damaged by their
use. Use clean cloths to remove dirt, carbon dust,
etc.
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, follow the recommended cord
sizes on the chart at right. When tool is used outdoors, use only extension cords suitable for outdoor

When electric tools are used on fiberglass
boats,
sports cars, etc., it has been found that they are subject to accelerated
wear and possible
premature
failure, as the fiberglass
chips and grindings
are
highly abrasive to bearings, brushes, commutator,
etc. Consequently
it is not recommended
that this
tool be used for extended work on any fiberglass
material. During any use on fiberglass it is extremely
important that the tool is cleaned frequently by blowing with
an air jet. ALWAYS
