of parts and any other condition that may affect the power tools operation. If

damaged, have the power tool repaired before use.

Many accidents are caused by

poorly maintained power tools.

Keep cutting tools sharp and clean.

Properly maintained cutting tools with sharp

cutting edges are less likely to bind and are easier to control.

Use the power tool, accessories and tool bits etc., in accordance with these

instructions and in the manner intended

for the particular type of power tool,

taking into account the working

conditions and the work to be performed.

Use of

the power tool for operations different from those intended could result in a hazardous

situation.

manufacturer or his agent in order to avoid a safety hazard.

SAFETY RULES FOR POWER SANDERS

HOLD TOOL by insulated gripping surfaces

when sanding where tool may contact

hidden wiring, such as walls, floors, or its own power cord. Contact with a “live” wire will

make exposed metals parts of the tool “live” and shock the operator.

INSPECT FOR AND REMOVE

all nails, screws, staples or any embedded pieces

of metal from surface to be sanded. These protrusions could damage the sandpaper,

the cushion of the sander and cause loss of control. Following this rule will reduce the

risk of serious personal injury and damage to the sander.

NEVER use this or any power sander for wet sanding or liquid polishing.

Failure to follow this rule will increase the risk of electric shock.

ALWAYS clamp the workpiece

securely so it will not move under the sander.

Unsecured work could be thrown towards the operator, causing injury.

DO NOT force the sander.

The weight of the sander supplies adequate

pressure. Let the sander and the grit on the sandpaper do the work.

DO NOT sand in any one place for too long.

The sander’s rapid action may

remove too much material and make the surface uneven.

CAUTION:

Keep the extension cord clear of the working area.

Position the cord so that it will not get caught on lumber, tools or other

obstructions while you are working with a power tool.

SAFETY INSTRUCTIONS cont.

WARNING:

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.

USE PROPER EXTENSION CORD.

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. Table 1 shows the correct

size to use depending on cord length and nameplate ampere rating. If in doubt,

use the next heavier gage. The smaller the gage number, the heavier the cord.
Table 1: Minimum Gage for Cord

WARNING:

Do not permit fingers to touch the terminals of plug when

installing or removing the plug from the outlet.

WARNING:

Double insulation DOES NOT take the place of normal safety

precautions when operating this tool.

ELECTRICAL SAFETY

Power tool plugs must match the outlet. Never modify the plug in any way. Do not

use any adapter plugs with grounded power tools.

Unmodified plugs and matching

outlets will reduce risk of electric shock.

Avoid body contact with grounded surfaces such as pipes, radiators, ranges and

refrigerators.

There is an increased risk of electric shock if your body is grounded.

Do not expose power tools to rain or wet conditions.

Water entering a power tool

will increase the risk of electric shock.

Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the

power tool. Keep cord away from heat, oil, sharp edges or moving parts.

Damaged

or entangled cords increase the risk of electric shock.

When operating a power tool outdoors, use an extension cord suitable for outdoor

use marked “W-A” or “W”.

Use of a cord suitable for outdoor use reduces the risk of

electric shock.

If operating a power tool in a damp location is unavoidable, use a Ground Fault

Circuit Interupter (GFCI) protected supply.

Use of a GFCI reduces the risk of

electric shock.

WARNING:

BE SURE to read and understand all instructions.

Failure to follow all instructions listed below may result in electric shock, fire

and/or serious personal injury.

SAFETY INSTRUCTIONS cont.

1. Harmful/toxic dusts will arise from sanding e.g. lead painted surfaces, woods and

metals. Contact with or inhalation of these dusts can endanger the health of operator

and bystanders. Always use eye glasses and dust mask.

2. Hearing protection should be worn when using the sander.

Always wear safety glasses or eye shields when using the sander. Everyday

eyeglasses have only impact-resistant lenses; they are not safety glasses.

Following this rule will reduce the risk of serious personal injury.

4. Remove the plug from the socket before carrying out any adjustment, servicing or

maintenance.

5. Fully unwind cable drum extensions to avoid potential overheating.

6. When an extension cable is required you must ensure it has the correct ampere rating

for your power tool and is in a safe electrical condition.

7. Ensure your mains supply voltage is same as indicated on the rating plate.

8. Your tool is double insulated for additional protection against a possible electrical

insulation failure within the tool.

9. Always check walls, floors and ceilings to avoid hidden power cables and pipes.

ADDITIONAL RULES FOR SAFE OPERATION

NOTE:

Only those dust masks suitable for working with lead paint dust and fumes should

be used. Ordinary painting masks do not offer this protection. See your local hardware

dealer for the proper (NIOSH approved) mask.

•

NO EATING, DRINKING OR SMOKING

should be done in the work area to

prevent ingesting contaminated paint particles. Workers should wash and

clean up

BEFORE

eating, drinking or smoking. Articles of food, drink, or

smoking should

NOT

be left in the work area where contaminated dust would

settle on them.

• Paint should be removed in such a manner as to minimize the amount of dust

generated.

• Areas where paint removal is occurring should be sealed with plastic sheeting

of 4 mils thickness.

• Sanding should be done in a manner to reduce tracking of paint dust outside

the work area.

• All surfaces in the work area should be vacuumed and thoroughly cleaned daily

for the duration of the sanding project. Vacuum filter bags should be changed

frequently.

• Plastic drop cloths should be gathered up and disposed of along with any dust

chips or other removal debris. They should be placed in sealed refuse receptacles

and disposed of through regular trash pick-up procedures. During clean up,

children and pregnant women should be

KEPT AWAY

from the immediate work

area.

• All toys, washable furniture and utensils used by children should be washed

thoroughly before being used again.

SAFETY INSTRUCTIONS cont.

• Lead from lead-based paints.

• Crystalline silica from bricks and cement and other masonry

products.

• Arsenic and chromium, from chemically treated lumber.

Your risk from these exposures varies, depending upon how often you do

this type of work. To reduce your exposure to these chemicals:

• Work in a well-ventilated area.

• Work with approved safety equipment, such as those dust

masks that

are specially designed to filter out microscopic particles.
Avoid prolonged contact with dust from power sanding, sawing, grinding,

drilling and other construction activities. Wear protective clothing and wash

exposed areas with soap and water. Allowing dust to get into your mouth,

eyes, or lay on the skin may promote absorption of harmful chemicals.

WARNING:

Some dust created by using power tools contains chemicals

known to the State of California to cause cancer and birth defects or other

reproductive harm. Some examples of these chemicals are:

WARNING:

Use of this tool can generate and/or disburse dust, which may

cause serious and permanent respiratory or other injury. Always use

NIOSH/OSHA approved respiratory protection appropriate for the dust exposure.

Direct particles away from face and body.

WARNING:

Collected sanding dust from sanding surface coatings

(polyurethane, linseed oil, etc.) can self-ignite in sander dust bag or elsewhere

and cause fire. To reduce risk, empty dust bag frequently and strictly follow

sander manual and coating manufacturer’s instructions.

CAUTION:

When working on metal surfaces, DO NOT use the dust bag

or a vacuum cleaner because sparks are generated. Wear safety glasses and a

dust mask. Due to the danger of fire, do not use your sander to sand magnesium

surfaces. Do not use for wet sanding.

SANDING LEAD BASED PAINT

NOT RECOMMENDED

due to the difficulty of

controlling the contaminated dust. The greatest danger of lead poisoning is to children

and pregnant women.

SANDING PAINTS

Since it is difficult to identify whether or not a paint contains lead without a chemical

analysis, we recommend the following precautions when sanding any paint:

•

children or pregnant women should enter the work area where the

paint sanding is being done until all clean up is completed.

• A dust mask or respirator should be worn by all persons entering the work

area. The filter should be replaced daily, or whenever (if) the wearer has

difficulty breathing.

Fig. 10

ORBITAL MOTION (see Fig. 9)

As shown in Figure 9, the orbit of the sander is 1/8-in. in diameter so the sandpaper

moves in tiny circles at very high speed, allowing the sander to move easily.

This orbital action duplicates a “hand sanding” motion for more aggressive sanding as you

push the sander forward. This powerful orbital action is ideal for heavy-duty sanding

applications, such as:
1. Removing old finishes

SELECTING THE RIGHT SANDPAPER

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.

Coarse grit will remove the most material and finer grit will give you 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:

• Sta

rt with a coarse grit and sand until the surface is uniform.

• Then use medium to rem

ove any scratches left by the coarse grit.

•

Then use a finer grit for finishing the surface.

Selecting the correct grit and type of sandpaper is an extremely important decision that

will allow you to achieve the best quality sanding finish.

WARNING:

DO NOT

wear loose clothing or jewelry when operating sander.

They could get caught in moving parts, causing serious injury. Keep head away from

sander and sanding area. Hair could be drawn into sander, causing serious injury.

NOTE: DO NOT

use the sander without sandpaper. This will damage the cushion.

NOTE: ALWAYS

continue sanding with each grit until the surface is uniform.

OPERATION cont.

SANDING TIPS

DO NOT force the sander.

The weight of the sander supplies adequate pressure on

the workpiece. Let the sander and the sandpaper’s grit do the work.

• Applying additional pressure will only slow down the motor, wear the sandpaper

out faster and reduce the sander’s orbital speed.

• Excessive pressure will overload the motor and cause possible damage to the

sander from the motor overheating.

• Excessive pressure will also result in a poor quality finish.

2. Any existing finish or resin on wood may soften from the heat of the friction and cause

the sandpaper to load-up faster.

3. Inspect sandpaper frequently and change paper when grit is worn and not able to

perform properly.

DO NOT

sand in one spot for too long a time because the sander’s rapid action may

remove too much material and make the surface uneven.

CAUTION:

To ensure proper brake operation after extended use, periodically

check its operation by removing the sanding disc and running the sander without

load (off the workpiece). The backing pad should not take longer than 6 seconds

to stop. If it takes longer than 6 seconds to stop, then brake should be replaced.

NOTE: The brake is available and can be purchased at the nearest Sears Parts

and Repair Center.

2. Remove (3) screws from top cover

of sander and remove top cover (see Fig. 11).
3. Locate the (2) Carbon Brush / Brush Holder

Assemblies (see Fig. 11a). They are connected

to red wire lead terminals and are in position

on each side of the armature.
4. Carefully lift these (2) assemblies (see Fig. 11a and 11b)

out of their positions

(NOTE: Remember how

they are positioned so that you can put them

back in position correctly.)

5. Check the ends of the carbon brushes (see Fig. 11b)

for wear. If either brush has less than 1/4-in. length

of carbon remaining, replace both.

DO NOT

REPLACE ONE SIDE WITHOUT REPLACING

THE OTHER.

6. To replace assemblies, disconnect

the red wire lead terminals from the

assemblies (see Fig. 11c), attach

new assemblies to the lead terminals

and place the assemblies back into

their original positions next to the

armature. Make sure the curvature

of the end of the brushes matches

the curvature of the armature and

that the brushes move freely in

brush holder assemblies.
7. Reassemble the top cap with the

(3) screws and do not overtighten.

Periodic maintenance allows for long life and trouble-free operation. A cleaning and

maintenance schedule should be maintained. As a common preventive maintenance

practice, follow these recommended steps:

1. When work has been completed, clean the tool to allow smooth functioning of the tool

over time. Clean the tool with compressed air.

2. Use clean damp cloths to wipe the tool. Use a brush to brush off and clean the sander’s

Backing Pad.

3. Keep the motor air openings free from oil, grease and sawdust or woodchips, and

store tool in a dry place.

WARNING:

DO NOT at any time let brake fluids, gasoline, petroleum-

based products, penetrating oils, etc. come in contact with plastic parts.

Chemicals can damage, weaken or destroy plastic, which may result in serious

personal injury.

WARNING:

For your safety, ALWAYS turn off switch and unplug sander

from the power source before performing any maintenance or cleaning.

ROUTINE MAINTENANCE

LUBRICATION

Your Craftsman

Professional Orbital Sander has been properly lubricated and is ready to

use. No further lubrication is needed under normal operating conditions. All bearings in the

sander are lubricated for the life of the tool.

MAINTENANCE

It has been found that electric tools are subject to accelerated wear and possible

premature failure when they are used to work on fiber glass boats and sports cars,

wallboard, spackling compounds or plaster. The chips and grindings from these materials

are highly abrasive to electrical 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 compound or plaster. During any use on these

materials, it is extremely important that the tool is cleaned frequently by blowing with

an air jet.

WARNING:

To ensure safety and reliability, repairs, maintenance and

adjustments MUST be performed by a qualified service technician.

WARNING:

For your safety, ALWAYS turn off switch and unplug sander

from the power source before performing any maintenance or cleaning.

WARNING:

Always wear safety goggles or safety glasses with side shields

during power tool operations, or when blowing dust. If operation is dusty, also

wear a dust mask.
