INTRODUCTION
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 insulationto protect the user. All exposed
metal parts are isolated from internal metal motor compo-
nents with protecting insulation.
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 we suggest you return the tool to your nearest
Sears Store for repair. Always use original factory replace-
ment parts when servicing.
RULES FOR SAFE OPERATION
READ ALL INSTRUCTIONS
1. KNOW YOUR POWER TOOL - Read owner's manual carefully. Learn its applications and limitations as well
as the specificpotentialhazards related to thistool.
2. GUARD AGAINST ELECTRICAL SHOCK BY PREVENTING BODY CONTACT WITH GROUNDED SUR-
FACES. For example: Pipes, radiators,ranges, refrigeratorenclosures.
3. KEEP GUARDS IN PLACE and in workingorder.
4. KEEP WORK AREA CLEAN. Cluttered areas and benches inviteaccidents.
5. AVOID DANGEROUS ENVIRONMENT. Don't use power tool in damp or wet locations or expose to rain.
Keep workarea well lit.
6. KEEP CHILDREN AND VISITORS AWAY. All visitors should wear safety glasses and be kept a safe
distance from workarea. Do not let visitorscontact tool or extensioncord.
7. STORE IDLE TOOLS, When not in use tools should be stored in a dry, high or locked-up place - out of the
reach of children.
8. DON'T FORCE TOOL. It will do the job better and safer at the rate for which it was designed.
9. USE RIGHT TOOL. Don't force small tool or attachment to do the job of a heavy duty tool. Don't use tool for
purpose not intended - for example - Don't use a circular saw for cutting tree limbs or logs.
10. WEAR PROPER APPAREL. No loose clothing or jewelry to get caught in moving parts. Rubber gloves and
non-skid footwear are recommended when working outdoors. Also, wear protective hair covering to contain
long hair and keep it from being drawn into air vents.
11. ALWAYS WEAR SAFETY GLASSES. Everyday eyeglasses have only impact-resistant lenses; they are
NOT safety glasses.

RULES FOR SAFE OPERATION (Continued)
12. PROTECT YOUR LUNGS. Wear a face ordust mask if operationis dusty.
13. PROTECT YOUR HEARING. Wear hearing protectionduringextended periodsof operation.
14. DON'T ABUSE CORD. Never carry tool by cord or yank it to disconnectfrom receptacle. Keep cord from
heat, oil and sharp edges.
15.__'SECUREWORK. Use clampsor a vise to holdwork. Bothhands are needed to operate the tool.
16. DON'T OVERREACH. Keep proper footing and balance at all times. Do not use on a ladder or unstable
support.
17. MAINTAIN TOOLS WITH CARE. Keep tools sharp at all times, and clean for best and safestperformance.
Follow instructionsfor lubricatingand changingaccessories.
18. DISCONNECT TOOLS. When not in use, before servicing,or when changing sanding disc, attachments,
blades, bits, cutters,etc., all°tools shouldbe disconnectedfrom power supply.
19. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys and adjusting
wrenches are rem_ed from tool before turningit on.
20. AVOID ACCIDENTAL STARTING. Don't carryplugged-intoolswith finger on switch. Be sure switchis off
when pluggingin.
21. MAKE SURE YOUR EXTENSION CORD IS IN GOOD CONDITION. When usingan extensioncord, be sure
to use one heavy enough to carry the currentyour productwilldraw. An undersized cordwill cause a drop in
line voltage resulting in loss of power and overheating. Awire gage size (A.W.G.) of at least 16 is
recommended for an extensioncord 100 feet or less in length.A cord exceeding 100 feet is notrecommend-
ed. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.
22. OUTDOOR USE EXTENSION CORDS. When tool is used outdoors,use only extensioncords suitablefor
use outdoors. Outdoor approved cords are markedwith the suffixW-A, for example - SJTW-A or SJOW-A.
23. NEVER USE THIS OR ANY POWER SANDER FOR WET SANDING OR LIQUID POLISHING. Failure to
comply can resultin electricalshockcausingserious injuryor worse.
24. KEEP HANDS AWAY FROM SANDING AREA.
25. NEVER USE IN AN EXPLOSIVE ATMOSPHERE. Normal sparkingof the motorcould ignitefumes.
26. INSPECT TOOL CORDS PERIODICALLY and if damaged, have repaired at your nearest Sears Repair
Center. Stay constantlyaware of cord location.
27. INSPECT EXTENSION CORDS PERIODICALLY and replace if damaged.
28. KEEP HANDLES DRY, CLEAN, AND FREE FROM OIL AND GREASE. Always use a clean cloth when
cleaning. Never use brake fluids, gasoline,petroleum-basedproducts or any strongsolvents to clean your
tool.
29. STAY ALERT. Watch what you are doing and use commonsense. Do notoperate toolwhenyou are tired.
Do not rush.
30. CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is damaged should be
carefully checked to determine that it will operate properlyand perform its intended function. Check for
alignment of movingparts, bindingof moving parts, breakage of parts, mounting, and any other conditions
that may affect its operation. Aguardor other part that is damaged shouldbe properlyrepaired or replaced
by an authorized servicecenter unless indicatedelsewhere in thisinstructionmanual.
31. DO NOT USE TOOL IF SWITCH DOES NOT TURN IT ON AND OFF. Have defective switchesreplaced by
an authorized servicecenter.
32. Inspect for and remove all nails from lumberbefore sanding.
33. DRUGS, ALCOHOL, MEDICATION. Do notoperate tool while underthe influence of drugs, alcohol,or any
medication._
34. When servicing use only identical Craftsman replacement parts.
35. POLARIZED PLUGS. To reduce the riskof electric shock,thistool has a polarized plug(one blade is wider
than the other). This plugwill fit ina polarized outlet only one way. If the plug does not fit fully inthe outlet,
reversethe plug. If it stilldoes notfit, contacta qualifiedelectricianto installthe properoutlet. Do notchange

FEATURES
Your sander is suitable for sanding with coarse, medium, and fine grit sanding discs. See Figure 1.
BEFORE'_.TTEMPTING TO USE YOUR SANDER, FAMILIARIZE YOURSELF WITH ALL OPERATING FEATURES AND
SAFETY REQUIREMENTS.
ELECTRICAL CONNECTION .,_
Your sander has a precision built electric motor. It should be connected to a power supply that is 120 volts, 60 Hz, AC only
(normal household current). D_not operate this tool on direct current (DC). A voltage drop of more than 10 percent will cause
a loss of power and overheating. If your tool does not operate when plugged into an outlet, double-check the power supply.
SWITCH
See Figure 1.
This tool is equipped with asimple switch control. To turn sander "ON", depress the switch button as shown in Figure 1.
Depress the switch button in the opposite direction to turn your sander "OFF". BE SURE SANDER SWITCH IS IN "OFF"
POSITION BEFORE CONNECTING TO POWER SUPPLY SOURCE.

The operation of any sander can result in foreign objects being thrown into your eyes, which I
can result in severe eye damage. Before beginning power tool operation, always wear safety I
goggles orsafety glasses with side shields and afull face shield when needed. We recommend I
Wide Vision Safety Mask for use over eyeglasses or standard safety glasses with side shields, I

OPERATION
APPLICATIONS
(USE ONLY FOR THE PURPOSES LISTED BELOW)
1. _Sanding woodsurfaces.
2. Removing rustfrom and sanding steel surfaces.
SANDING DISC SELECTION _
Selecting the correct size _rit and type sanding disc 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 forfinishing of the surface. Always continue sanding
with each grit until surface is uniform.
TO ATTACH SANDING DISC
See Figure 2.
The backing pad on your sander accepts pressure sensitive
adhesive backed sanding discs. Therefore, you must only
use pressure sensitive adhesive backed sanding discs with
this sander.
1. Unplugyoursander.
SANDING DISC
KING PAD

2. Carefully peel adhesive backing from new sanding disc.
3. Align holes in sanding disc with holes in backing pad, then
carefully press sticky side of disc against pad as tight as
posssible.

SANDING ,_
See Figure 3.
Place sander on workpiece sothat all of sanding discsurface
is in contact with workpiece. Start your sander and move it
slowlyover workpiece making successive passes inparallel
lines, circles, orcrosswise movements. Upon completion of
sanding operation, turn sander offand wait untilsanding disc
comes to a complete stop before removing from workpiece.
DO NOT FORCE, The weight of the unit supplies adequate
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
sander's rapid action may remove too much material, making
the surface uneven.

MAINTENANCE
GENERAL
Only the parts shown on parts list, page 11, are intended to
be rqpaired or replaced by the customer. All other parts
represent an important part of the double insulation system
and should be serviced only by a qu_ified Sears service
technician.
Avoid using solvents whe_cleaning plastic parts. Most
plastics are susceptible to various types of commercial sol-
vents and may be damaged by their use. Use clean cloths to
remove dirt, carbon dust, etc.
When electric tools are used on fiberglass boats, sportscars,
wallboard, spackling compounds, or plaster, it has been
found that they are subject to accelerated wear and possible
premature failure, as the fiberglass chips and grindings are
highlyabrasive to bearings, brushes, commutator, etc. Con-
sequently it is not recommended that this tool be used for
extended work on any fiberglass material, wallboard, spack-
ling compounds, or plaster. During any use on these mate-
rials, it is extremely important that the tool is cleaned fre-
quently by blowing with an air jet.
EXTENSION CORDS
The use ofany extension cord willcause some loss of power.
To keep the loss to a minimum and to prevent tool overheat-
ing, use an extension cord that is heavy enough tocarry the
current the tool will draw. Follow the recommended cord
sizes on the chart provided to determine the minimum wire
size required in an extension cord.
Extension Cord Length Wire Gauge Size (A.W.G.)
25-50 FEET '18
50-100 FEET 16
When working with your tool outdoors,use an extension cord
suitable for outdoor use and so marked. Outdoor use
extension cords are marked with the letters "WA" on the
cord's jacket.
CAUTION: Keep extension cords away from the sanding
area and position the cord so that it will not get caught on
lumber, tools, etc., during sanding operation.
LUBRICATION
All of 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, nofurther lubrica-
tion is required.
