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. All exposed metal

parts are isolated from internal metal motor

components with protecting insulation. Double

insulated tools do not need to be grounded.

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 replacement parts when servicing.

WARNING: Do not attempt to operate this tool

until you have read thoroughly and understand

completely all instructions, safety rules, etc.

contained in this manual. Failure to comply can

result in accidents involving fire, electric shock,

or serious personal injury. Save owner's manual

and review frequently for continuing safe

operation, and instructing others who may use

this tool.

READ ALL INSTRUCTIONS

KNOW YOUR POWER TOOL. Read owner's

manual carefully. Learn its applications and

limitations as well as the specific potential

hazards related to this tool.

GUARD AGAINST ELECTRICAL SHOCK BY

PREVENTING BODY CONTACT WITH

GROUNDED SURFACES. For example; pipes,

radiators, ranges, refrigerator enclosures.

KEEP GUARDS IN PLACE AND IN WORKING

ORDER.

KEEP WORK AREA CLEAN. Cluttered areas

and benches invite accidents.

AVOID DANGEROUS ENVIRONMENT. Don't

use power tools in damp or wet locations or

expose to rain. Keep work area well lit.

KEEP CHILDREN AND VISITORS AWAY. All

visitors should wear safety glasses and be kept a

safe distance from work area. Do not let visitors

contact tool or extension cord.

should be stored in a dry and high or locked-up

place - out of the reach of children.

DON'T FORCE TOOL. It will do the job better

and safer at the rate for which it was designed.

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 - A circular saw should never be used

for cutting tree limbs or logs.

WEAR PROPER APPAREL. Do not wear loose

clothing or jewelry that can get caught in tool's

moving parts and cause personal injury. Rubber

gloves and nonskid footwear are recommended

RULES FOR SAFE OPERATION (Continued)

when working outdoors. Wear protective hair

covering to contain long hair and keep it from

being drawn into nearby air vents.

ALWAYS WEAR SAFETY GLASSES. Everyday

eyeglasses have only impact-resistant lenses;

they are not safety glasses.

PROTECT YOUR LUNGS. Wear a face or dust

mask if the operation is dusty.

PROTECT YOUR HEARING. Wear hearing

protection during extended periods of operation.

DON'T ABUSE CORD. Never carry tool by cord

or yank it to disconnect from receptacle. Keep

cord from heat, oil, and sharp edges.

•SECURE WORK. Use clamps or a vise to hold

work. It's safer than using your hand and it frees

both hands to operate tool.

•DON'T OVERREACH. Keep proper footing and

balance at all times. Do not use while standing

on a ladder or unstable support. Secure tools

when working at elevated positions.

MAINTAIN TOOLS WITH CARE. Keep tools

sharp and clean for best and safest performance.

AVOID ACCIDENTAL STARTING. Don't carry

plugged-in tool with finger on switch. Be sure

switch is off when plugging in.

MAKE SURE YOUR EXTENSION CORD IS IN

GOOD CONDITION. When using an extension

cord, be sure to use one heavy enough to carry

the current your product will draw. An undersized •

cord will cause a drop in line voltage resulting in

loss of power and overheating. A wire gage size

(A.W.G.) of at least 14 is recommended for an •

extension cord 100 feet or less in length. A cord

exceeding 100 feet is not recommended. If in

doubt, use the next heavier gage. The smaller •

the gage number, the heavier the cord.

OUTDOOR USE EXTENSION CORDS. When

tool is used outdoors, use only extension cords

suitable for use outdoors. Outdoor approved

cords are marked with the suffix W-A, for ex-

ample -SJ'FW-A or SJOW-A.

SPHERE. Normal sparking of the motor could

ignite fumes.

INSPECT TOOL CORDS PERIODICALLY and if

damaged, have repaired at your nearest Sears

Repair Center. Stay constantly aware of cord

location and keep it well away from the sanding

area.

INSPECT EXTENSION CORDS PERIODI-

CALLY and replace if damaged.

KEEP HANDLES DRY, CLEAN, AND FREE

FROM OIL AND GREASE. Always use a clean

cloth when cleaning, Never use brake fluids,

gasoline, petroleum-based products, or any

strong solvents to clean your tool.

STAY ALERT AND EXERCISE CONTROL.

sense. Do not operate tool when you are tired.

Do not rush.

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 properly and perform its intended

function. Check for alignment of moving parts,

binding of moving parts, breakage of parts,

mounting and any other conditions that may

affect its operation. A guard or other part that is

damaged should be properly repaired or re-

placed by an authorized service center.

DO NOT USE TOOL IF SWITCH DOES NOT

TURN IT ON AND OFF. Have defective switches

replaced by an authorized service center.

INSPECT FOR and remove all nails from lumber

before sanding.

DO NOT operate this tool while under the

influence of drugs, alcohol, or any medication.

DO NOT USE THIS SANDER FOR OVERHEAD

SANDING. Overhead sanding could result in

dropping sander or loss of control. These situa-

tions could result in an accident resulting in

possible serious injury.

RULES FOR SAFE OPERATION (Continued)

POLARIZED PLUGS. To reduce the risk of

electric shock, this tool has a polarized plug (one

blade is wider than the other). This plug will fit in

,_WARNING: To prevent the possibility of sawdust

or foreign objects being thrown into your face and

eyes, never attempt to use your sander without

dust bag properly installed. Sawdust or foreign

objects being thrown into your face and eyes

could result in possible serious injury.

SANDING BELT SELECTION

Selecting the correct size and type of sanding belt is

an important step in achieving a high quality sanded

finish. Standard 4 in. x 21 in. 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 fine grit

will produce the smoothest 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

fine grit belt used for finishing of the surface. Always

continue sanding with each grit belt until the surface is

uniform.

INSTALLING/REMOVING SANDING BELT

• Unplug your sander.

_. WARNING: Failure to unplug your sander could

result in accidental starting causing possible

serious personal injury.

• Position sander as shown in figure 3.

_1= WARNING: Keep hands and fingers clear of

,_ WARNING: Unsecured work could be thrown

back toward operator causing injury.

Before placing sander on work surface, squeeze the

switch trigger and let the motor reach its maximum

speed, then lower your sander to the work surface

with a slight forward motion. Using the rear handle to

control your sander and the front handle only to guide

it, move it slowly over the work. Allowing your sander

to remain in one place will result in an uneven sur-

face.

,_ 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.

Your sander was designed to provide the proper

weight on the sanding belt.

Excessive pressure will result In the following:

•Uneven work.

• Clogged sanding belts.

• Premature sanding belt wear. Removal rate will

not increase.

•Possible motor burnout.

•Irregular sanding belt tracking.

Note: If the sanding belt moves while sanding, you

may be applying too much pressure. When this

occurs remove sander from workpiece. If belt tracking

is properly adjusted, sanding belt will return to its

normal and correct position on the drive roller and

front roller.

Use a coarser belt when heavy sanding is desired, not

heavy pressure. The importance of this cannot be

overemphasized. Weight has been built into the tool

to give the most efficient pressure at the proper

location.

Note: The front roller of your sander was not de-

signed for contour sanding. Sanding on the front roller

could cause irregularity in sanding belt tracking. H

GENERAL

Only the parts shown on parts list, page 17, 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 Sears service technician.

Avoid using solvents when cleaning plastic pads.

Most plastics are susceptible to damage from various

types of commemial solvents and may be damaged

by their use. Use clean cloths to remove dirt, carbon

dust, etc.

,_ WARNING: Do not at any time let brake fluids,

gasoline, petroleum-based products, penetrating

oils, etc. come in contact with plastic pads. They

contain chemicals that can damage, weaken or

destroy plastic.

It has been found that electric tools are subject to

accelerated wear and possible premature failure when

they are used on fiberglass boats, sports cars,

wallboard, spackling compounds, or plaster. The

chips and gdndings from these materials are highly

abrasive to electric tool parts such as bearings,

brushes, commutators, etc. Consequently, it is not

recommended that this tool be used for extended

work on any fiberglass material, wallboard, spackling

compounds, or plaster. During any use on these

materials it is extremely important that the tool is

cleaned frequently by blowing with an air jet.

_i, WARNING: Always wear safety goggles or

safety glasses with side shields during power tool

operation or when blowing dust. If operation is

dusty, also wear a dust mask.

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,

no further lubrication is required.

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 an extension cord that is heavy

enough to carry the current the tool will draw.

A wire gage size (A.W.G.) of at least 14 is

recommended for an extension cord 100 feet or less

in length. When working outdoors, use an extension

cord that is suitable for outdoor use. The cord's jacket

will be marked WA,

_1= 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.

AWARNING: Check extension cords before each

use. If damaged replace immediately. Never use

tool with a damaged cord since touching the

damaged area could cause electrical shock

resulting in serious injury.
