This tool has many features for making its use more pleasant and enjoyable. Safety, performance, and dependability have been given top priority in the design of this product making it easy to maintain and operate.

_h WARNING: Read and understand all instruc-

tions. Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS

WORK AREA

• Keep the work area clean and well lit. Cluttered benches and dark areas invite accidents.

• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liq-

uids, gases, or dust.

Power tools create sparks which may ignite the dust or fumes.

• Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

• Double insulated tools are equipped with a polar- ized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug.

If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double insulation [] eliminates the need for the three-wire grounded power cord and grounded power supply system.

• Avoid body contact with grounded surfaces such as

pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if the body is grounded.

• Don't 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 to carry the tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges, or moving parts.

Replace damaged cords immediately.

Damaged cords increase the risk of electric shock.

• When operating a power tool outside, use an outdoor extension cord marked "W-A" or "W". These cords are rated for outdoor use and reduce the risk of electric shock.

PERSONAL SAFETY

• Stay alert, watch what you are doing and use com- mon sense when operating a power tool. Do not

use tool while tired or under the influence of drugs, alcohol, or medication.

A moment of inattention while operating power tools may result in serious personal injury.

• Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep the hair, clothing,

and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.

• Avoid accidental starting.

Be sure switch is off

before plugging in. Carrying tools with the finger on the switch or plugging in tools that have the switch on invites accidents.

• Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury.

• Do not overreach.

Keep proper footing and balance at all times.

Proper footing and balance enables better control of the tool in unexpected situations.

• Use safety equipment.

Always wear eye protection.

Dust mask, nonskid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.

• Do not wear loose clothing or jewelry.

Contain long

hair. Loose clothes, jewelry, or long hair can be drawn into air vents.

• Do not use on a ladder or unstable support.

Stable footing on a solid surface enables better control of the tool in unexpected situations.

TOOL USE AND CARE

• Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against the body is unstable and may lead to loss of control.

• Do not force tool. Use the correct tool for the appli-

cation. The correct tool will do the job better and safer at the rate for which it is designed.

• Do not use tool if switch does not turn it on or off.

Any tool that cannot be controlled with the switch is dangerous and must be repaired.

• Disconnect the plug from power source before making any adjustments, changing accessories,

or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.

• Store idle tools out of the reach of children and

other untrained persons. Tools are dangerous in the hands of untrained users.

• Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edges are less likely to bind and are easier to control.

• Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool's operation. If damaged, have

the tool serviced before using. Many accidents are caused by poorly maintained tools.

• Use only accessories that are recommended by the manufacturer for the model. Accessories that may be suitable for one tool, may become hazardous when used on another tool.

• Keep the tool and its handle dry, clean and free from oil and grease. Always use a clean cloth when cleaning. Never use brake fluids, gasoline, petroleumbased products, or any strong solvents to clean the tool. Following this rule will reduce the risk of loss of control and deterioration of the enclosure plastic.

SERVICE

• Tool service must be performed only by qualified

repair personnel. Service or maintenance performed by unqualified personnel may result in a risk of injury.

• When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of shock or injury.

• Hold tool by insulated gripping surfaces when

performing an operation where the cutting tool may

contact hidden wiring or its own cord. Contact with a "live" wire will make exposed metal parts of the cutting tool "live" and shock the operator.

• Know the power tool. Read operator's manual carefully. Learn its applications and limitations, as well as the specific potential hazards related to this tool.

Following this rule will reduce the risk of electric shock, fire, or serious injury.

• Always wear safety glasses. Everyday eyeglasses have only impact-resistant lenses; they are NOT

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

• Protect the lungs. Wear a face or dust mask if the operation is dusty. Following this rule will reduce the risk of serious personal injury.

• Protect the hearing. Wear hearing protection during extended periods of operation.

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

• Inspect tool cords periodically and, if damaged,

have repaired at the nearest Authorized Service

Center. Constantly stay aware of cord location.

Following this rule will reduce the risk of electric shock or fire.

• 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 replaced by an authorized

service center. Following this rule will reduce the risk of shock, fire, or serious injury.

• Make sure the extension cord is in good condition.

When using an extension cord, be sure to use one heavy enough to carry the current the product will draw. A wire gauge size (A.W.G.) of at least 16 is recommended for an extension cord 50 feet or less in length. A cord exceeding 100 feet is not recommended. If in doubt, use the next heavier gauge.

The smaller the gauge number, the heavier the cord. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.

• Inspect for and remove all nails from lumber before

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

• Save these instructions.

Refer to them frequently and use them to instruct others who may use this tool. If you loan someone this tool, loan them these instructions also.

_ WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry products, and

• arsenic and chromium from chemically-treated lumber.

The risk from these exposures varies, depending on how often you do this type of work. To reduce the exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

SAVE THESE INSTRUCTIONS

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 the internal metal motor components with protecting insulation.

Double insulated tools do not need to be grounded.

,_ WARNING: The double insulated system is intended to protect the user from shock resulting from a break in the tool's internal insulation. Observe all normal safety precautions to avoid electrical shock.

NOTE: 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 the nearest authorized service center for repair. Always use original factory replacement parts when servicing.

ELECTRICAL CONNECTION

This tool 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). Do not operate this tool on direct current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat. If the tool does not operate when plugged into an outlet, double-check the power supply.

EXTENSION CORDS

When using a power tool at a considerable distance from a power source, be sure to use an extension cord that has the capacity to handle the current the tool will draw. An undersized cord will cause a drop in line voltage, resulting in overheating and loss of power. Use the chart to determine the minimum wire size required in an extension cord.

Only round jacketed cords listed by Underwriter's Laboratories (UL) should be used.

When working outdoors with a tool, use an extension cord that is designed for outside use. This type of cord is designated with "WA" on the cord's jacket.

Before using any extension cord, inspect it for loose or exposed wires and cut or worn insulation.

APPLICATIONS

You may use this tool for the purposes listed below:

• Sanding wood surfaces

• Removing rust from and sanding steel surfaces

SELECTING SANDING DISCS

Selecting the correct size grit 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 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 for finishing of the surface. Always continue sanding with each grit until surface is uniform.

ATTACHING VELCRO ® TYPE SANDING DISCS

See Figure 2.

• Unplug the sander.

• Align the holes in the sanding disc with the holes in the hook and loop backing pad.

NOTE: Holes in sanding disc must line up with holes in the backing pad in order for the dustless feature of the sander to function properly.

• Press the sanding disc against the backing pad as firmly as possible.

NOTE: For best adhesion, we recommend that you clean the backing pad and the sanding disc backing occasionally by brushing them lightly with a small brush.

DUSTBAG

DUST

EXHAUST

Fig. 3

The dust bag assembly provides a dust collection system for the sander. It can be installed by aligning the arrow on the dust bag with the the lug on the dust exhaust. When fully seated, twist clockwise to lock. Sanding dust is drawn up through the holes of the sanding disc to collect in the dust bag during sanding operation.

NOTE: For more efficient operation, empty dust bag when no more than half full. This will permit the air to flow through the bag better.

A WARNING: Collected sanding dust from sanding surface coatings such as polyurethanes, linseed oil, etc., can self-ignite in the sander dust bag or elsewhere and cause fire. To reduce the risk of fire, always empty the dust bag frequently

(10-15 minutes) while sanding and never store or leave a sander without totally emptying its dust bag. Also follow the recommendations of the coatings manufacturers.

ATTACHING SANDER TO VACUUM

See Figure 5.

When sanding for an extended period of time, you can easily attach the dust collection system of the sander to a vacuum.

To Attach:

• Unplug the sander.

• Remove dust bag from sander.

• Attach vacuum hose to dust exhaust.

NOTE: Vacuum hose fits inside dust exhaust.

• Connect sander and vacuum to power supply.

_ WARNING: When sander is not connected to vacuum, always install dust bag back on sander.

Failure to do so could cause sanding dust or foreign objects to be thrown into the face or eyes which could result in possible serious injury.

_ WARNING: Before connecting the sander to power supply source, always check to be sure the switch is not in the ON position.

Failure to do so could result in accidental starting of the sander resulting in possible serious injury.

_lb CAUTION: Be careful not to let the hand cover the air vents.

ON/OFF SLIDE SWITCH

This sander is equipped with a simple slide switch control.

To turn the sander ON, slide the switch in the direction shown by the arrow in figure 1. To turn the sander OFF, slide the switch in the opposite direction.

VARIABLE SPEED SWITCH, MODEL 279890 ONLY

The variable speed feature allows the sander to operate at speeds that can be adjusted by rotating the dial on the variable speed switch from A to E The dial is conveniently located on the motor housing, allowing operator control of disc speed. To increase sanding disc speed, turn the dial on the variable speed switch to a higher setting. Turn dial to a lower setting to decrease sanding disc speed.

SANDING

See Figures 6 - 7.

Clamp or otherwise secure the work to prevent it from moving under the sander.

_ WARNING: Unsecured work could be thrown towards the operator causing injury.

Place sander on workpiece so that all of sanding disc surface is in contact with workpiece. Start the sander and move it slowly over workpiece making successive passes in parallel lines, circles, or crosswise movements.

Upon completion of sanding operation, turn sander off and wait until sanding 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 the sander's rapid action may remove too much material, making the surface uneven.

Extended periods of sanding may tend to overheat the motor. If this occurs, turn sander off and wait until sanding disc comes to a complete stop, then remove it from workpiece.

Remove the hand from vent area, remove sanding disc, then with the hand removed from vent area, turn sander on and run it free without a load to cool motor.

Flush sanding can be performed with the sander. The front edge of the sander allows flush sanding. Upon completion of sanding operation, turn sander off and wait until sanding disc comes to a complete stop before removing from workpiece.

_ 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 through Replacement Parts at the nearest Sears Service

Center.

_ WARNING: When servicing, use only identical

Craftsman replacement parts. Use of any other parts may create a hazard or cause product damage.

_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.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use.

Use clean cloths to remove dirt, dust, oil, grease, etc.

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.

Electric tools used on fiberglass material, wallboard, spackling compounds, or plaster are subject to accelerated wear and possible premature failure because the fiberglass chips and grindings are highly abrasive to bearings, brushes, commutators, etc. Consequently, we do not recommended using this tool for extended work on these types of materials. However, if you do work with any of these materials, it is extremely important to clean the tool often using compressed air.

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.

Only the parts shown on the parts list are intended to be repaired or replaced by the customer. All other parts should be replaced at a Sears Service Center.

CLEANING DUST BAG ASSEMBLY
