INTRODUCTION
DOUBLE INSULATION is aconcept 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.
Your sander is suitable for coarse, medium and fine
sanding of wood, plasters, metals and plastics. It is
ideal when used for leveling wallboard, finishing
cabinets and many other general sanding ap-
plications. It may also be used asapolisher when
using apolishing pad instead of sandpaper. Your
sander will produce afine scratch free finish when
used with or against the grain and is designed for
sanding flush to corners.
IMPORTANT—Servicing of atool with double in-
sulation requires extreme care and knowledge of the
system and should be performed only by aqualified
service technician. For service we suggest you
return the tool to your nearest Sears Store for repair.
Always use original factory replacement parts when
servicing.
The dual motion feature with which your sander is
equipped is ideal for any sanding operation where a
pad sander is required. Orbital motion is ideal for
fast cutting action when removing old finishes,
smoothing rough wood, cutting stock down to
required dimensions or for finishing surface to be
painted. Straight line is best for fine finish sanding
on work to be stained or varnished or for use with a
polishing pad.
The built-in dust collection system will remove most of the sanding dust from the work and
eliminate the dust in the air —usually associated with power sanding.
RULES FOR SAFE OPERATION
1.KNOW YOUR POWER TOOL —Read owner’s manual carefully. Learn its applications and limitations as well
as the specific potential hazards peculiar to this tool.
2. GROUND ALL TOOLS —UNLESS DOUBLE-INSULATED. If tool is equipped with three-prong plug, it should
be plugged into athree-hole electrical receptacle. If adapter is used to accommodate two-prong receptacle,
the adapter wire must be attached to aknown ground. (Usually the screw securing receptacle cover plate).
Never remove third prong.
3. KEEP GUARDS IN PLACE and in working order.
4. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
5. AVOID DANGEROUS ENVIRONMENT. Don’t use power tool in damp or wet locations or expose to rain. Keep
work area well lit.
6KEEP CHILDREN AWAY. All visitors should be kept safe distance from work area.
7STORE IDLE TOOLS. When not in use, tools should be stored in dry, high or locked-up place—out of 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 aheavy duty tool.
10. WEAR PROPER APPAREL. No loose clothing or jewelry to get caught in moving parts. Rubber gloves and
footwear are recommended when working outdoors.
11 .USE SAFETY GLASSES with most tools. Also face or dust mask if cutting operation is dusty.
12. DON’T ABUSE CORD. Never carry tool by cord or yank it to disconnect from receptacle. Keep cord from heat,
oil and sharp edges. ,...... ......
13. SECURE WORK. Use clamps or avise to hold work. It’s safer than using your hand and it frees both hands to
operate tool.
14DON’T OVERREACH. Keep proper footing and balance at all times.
15. MAINTAIN TOOLS WITH CARE. Keep tools sharp at all times, and clean for best and safest performance.
Follow instructions for lubricating and changing accessories.
16. DISCONNECT TOOLS when not in use, before servicing; when changing attachments, blades, bits,
cytters etc
17. REMOVE At JUSTING KEYS AND WRENCHES. Form habit of checking to see that keys and adjusting
wrenches are removed from tool before turning it on.
18. AVOID ACCIDENTAL STARTING. Don’t carry plugged-in tools with finger on switch. Be sure switch is off
when plugging in.
19 OUTDOOR USE EXTENSION CORDS. When tool is used outdoors, use only extension cords suitable for use
outdoors and so marked.

OPERATION
ATTACHING DUST BAG
Disconnect sander from power supply.
1.
Place dust bag support (A) into notch (B) in
nozzle (C) as shown in Fig. 1.
2. Put open end of dust bag over dust bag support
and end of nozzle. Make sure bag is over rim on
nozzle and tie draw string securely.
Note: Empty the Dust Bag frequently by untying the
draw string and shaking out the bag. Alarge
amount of dust or heavy coating on the inside of
the bag will slow the movement of the air carrying
the dust and make the pick-up lose its ef-
fectiveness.
Your sander is equipped with its own built-in
auxiliary handle located at the front of the unit. This
handle allows for two-hand use which will aid in
maintaining complete control and keeping sanding
area level with work piece. (See Fig. 2)
SANDPAPER SELECTION
Selecting the correct size and type sandpaper is an
extremely important step in achieving ahigh quality
sanded finish. Aluminum oxide, silicone carbide and
other synthetic abrasives are best for power san-
ding. Other natural abrasives, such as flint and
garnet sandpaper are too soft for economical use in
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
sandpaper will do the job. If the surface is rough,
start with acoarse grit paper sanding until surface is
uniform. Medium grit paper may then be used to
remove scratches left by the coarser paper and finer
grit paper used for finishing of the surface. Always
continue sanding with each grit paper until surface
is uniform.
INSTALLING SANDPAPER (See Fig. 3)
Disconnect Sander from power supply.
1. Pull on the dust skirt at points (D) and (E) to
remove top edge of skirt from groove in sander.
2. Pull skirt at point (C) and lift it up to remove from
groove.
3. After skirt has been removed from groove slide it
up on sander to expose sandpaper retainer (A)
4. Raise sandpaper retainer (A) with lever (B).
5. Insert end of sandpaper approximately Vi inch
beyond front edge of retainer.
6. Release retainer and apply downward pressure to
conform sandpaper to platen.
7. Wrap sandpaper around cushion, raise the
retainer on the opposite end of sander and insert
loose end of sandpaper under retainer. Fit
sandpaper against cushion as tight as possible.
8. Release sandpaper retainer and again apply
downward pressure to form the sandpaper.
9. Replace the dust skirt in its original position.
MOTION SELECTION
The dual motion feature of your sander with its
readily accessible slide lever for quick motion
setting provides required motion for any sanding
application. If your particular requirement is fast
cutting action for removing old finishes, smoothing
rough wood, cutting stock down to required
dimensions or for sanding of surfaces to be painted,
orbital motion is best suited. For fine finish sanding
on work to be stained or varnished and for use with
polishing pad, straight line motion is ideal.
SETTING MOTION
Disconnect sander from power supply.
1. Do not change motion setting while unit is
operating.
2. For orbital motion slide lever (A) toward the O
mark on platen as far as possible. See Figure 4.
3. For straight line motion slide lever (A) toward the
—mark on platen as far as possible.

OPERATION (CONTINUED)
While holding your sander firmly in front of and
clearly away from you, with the sanding surface
clear of any foreign material, slide switch starting
sanding action. Place the sander gently onto the
work and move slowly using forward and backward
strokes. DO NOT FORCE. The weight of the unit
supplies adequate pressure, so let the sanding sheet
and sander do the work. Applying additional
pressure only slows the motor, rapidly wears
sandpaper and greatly reduces speed. Excessive
pressure will overload the motor causing possible
damage from motor overheating and can result in
inferior work as any finish or resin on wood may
soften from the frictional heat. Sanding with the
grain of wood gives the smoothest finish while
sanding against the grain results in faster sanding.
(See Fig. 5) The sander can move the length of the
entire surface, however, do not allow sanding on one
spot too long as its rapid action may remove too
much material making the surface uneven. Always
remove sander from work piece before sliding switch
into “Off” position stopping sanding action.
MAINTENANCE
WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT PARTS.
LUBRICATION
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.
Fig. 6
After 50 hours use, the platen with cushion, Key No.
20, should be removed by removing the four (4)
screws, Key No. 22. The bearing block, Key, No. 18,
and slide on platen with cushion should be wiped
clean and re-lubricated with agood grade of light
grease.
NOTE: The Bearing Block, Key No. 18, is so
designed that when worn it may be rotated 90°,
engaging the platen lever in the alternate notch,
thereby giving avirtually new part.
BRUSH REPLACEMENT
IMPORTANT -BE SURE POWER CORD IS
DISCONNECTED FROM POWER SUPPLY. To
replace carbon brushes (See Fig. 6) unscrew brush
caps No. 4, (see parts list, page 7). Remove Washer
Key No. 5. The washer is atight fit in the brush
holder and its purpose is to prevent the brush spring
twisting when replacing brush caps. Remove old
brush, Key No. 6. Reassemble new brush and spring
making sure that curvature of brush matches cur-
vature of the surface of the motor to which it is
mated and that the brush moves freely in holder.
Replace washers and caps. Be sure that brush caps
are tight.

GENERAL
WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT PARTS
Only the parts shown on parts list, page seven, 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 aqualified 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 aminimum and to
prevent tool overheating, use minimum 16 A.W.G.
wire size for extension cord lengths from 25 to 100
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 continuous production 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.
feet. When tool is used outdoors, use only extension
cords suitable for outdoor use and so marked.
Extension cords are available at Sears Catalog Order
or Retail Stores.
The operation of any power tool can result in foreign
objects being thrown into the eyes, which can result
in severe eye damage. Always wear safety glasses or
eye shields before commencing power tool
operation. We recommend Wide Vision Safety Mask
for use over spectacles, or standard safety glasses
...available at Sears retail or catalog stores.
