INTRODUCTION
GENERAL
Your Craftsman 3-lnch 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.
IMPORTANT -- Servicing of a tool with double In-
sulation 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 wilt be
done with original factory replacement parts.
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 supp-
ly system Wherever there ts electric current _nthe
too! there are two complete sets of insulation to pro-
tect the user Alt exposed metal parts are isolated
from the tnternat metal motor components with pro..
tecttng insulation.

Page 3
OPERATION
Make sure power supply is 110-120 volts, 60 HZ, AC
only.
Before attempting to use your Sander, familiarize
yourself with all operating features (See Figure 1)
and safety requirements.
SWITCH
The switch of your sander is equipped with a "lock-
on" feature which is convenient when sanding for
extended periods of time, To lock-on, simply depress
the trigger of the switch, push in the lock button
located on the side of the handle, then while holding
the lock button pushed in, release the trigger See
Figure 2 To release the lock, depress the trigger and
release it If you have the "Lock-On" feature engaged
during use and your Sander becomes disconnected
from power supply, disengage the "Lock-On" feature
immediatel,
PREPARING FOR OPERATION
For ease of operation and maintaining proper con..
trot, your Sander has a front handle and a rear han
die These handles allow two-hand operation which
aid in maintaining controi, keeping sanding area
level with workpiece, and keeping hands clear of
sanding belt. When operating your Sander always
hold the front handle with your left hand and the rear
handle with your right hand as shown in Fig. 2.

OPERATION
Selecting the correct size and type sanding beit is an
important step in achieving ahigh quality sanded
finish. Standard 3 inch x 21 inch sanding belts made
'of alumt'num oxide, silicone carbide, and other syn-
thetic abrasives are best for power sanding, in
general, coarse grit will remove the most material
and fine grit wilt produce the smoothest fintsh in alt
sanding operations. The condition of the surface to
be sanded wtlt 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 fine grit belt used for finishing
of the surface. Always continue sanding with each
grit belt until the surface is uniform

ALWAYS WEAR SAFETY GOGGLES OR SAFETY .......... '........
GLASSES WiTH SIDE SHIELDS WHEN OPERATING
YOUR SANDER To adust sanding belt, connect
Sander to power supply Place Sander in upside
down position as shown in Figure 7, NOTE: This
position is for adjustments only. The Sander ts not in
an operating position Putl switch trtgger 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, tt may become necessary to
change the adjustment several times until the bett
becomes )liable.
When you are sure the belt will not rub against inter-
nal parts start your Sander and fine adjust the track-
ing screw until the belt stab zes See Figure 8
When correctly adjusted, the outer edge of the belt
wilt be even with the outer edge of the base of your
Sander. #ell life wilt be greatly increased if a few
seconds are spent adjusting the belt tracking.
Before placing Sander on work surfac
squeeze the trigger switch and let the motor reach
its maximum speed, then toweryour Sander to the
work surface with a slight forwardmotion Using the
rear handle to control your Sander and the front han-
dle only to guide it, move it slowly over the work See
Fig 9. Allowing your Sander to remain in one place
will result in an uneven surface.
Your sander was designed to provide the proper
weight on the sanding belt Extra pressure wilt result
in uneven work, clogged belts, and possible motor
burnout. NOTE: The front roller of your sander was
not designed for contour sanding Sanding on lhe
front ro!ler could cause irregularity in sanding belt
tracking
Use a coarser 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
TO OPERATE
Clamp or otherwise secure the work to prevent it
from moving under your Sander.

material During any use on fiberglass it is extremely
important that the tool is cleaned frequently by blowo
ing with an air jet ALWAYS WEAR SAFETY GOG-
GLES, SAFETY GLASSES WITH SIDE SHIELDS, OR
