,_ WARNING: Read and understand all instructions. Failure to follow all instructions listed
below, may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
WORK AREA
???Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
???Do not operate power tools in explosive atmo- spheres, such as in the presence of flammable liquids, 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 polarized 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 insula-
tion [] eliminates the need for the
???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.
???Don'texpose power tools to rain or wet condi- tions. 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 immedi-
ately. Damaged cords increase the risk of electric shock.
???When operating a power tool outside, use an outdoor extension cord marked
risk of electric shock.
PERSONALSAFETY
???Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inatten- tion while operating power tools may result in serious personal injury.
???Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, cloth- ing, 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 your 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 protec- tion. 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.
TOOLUSEAND CARE
???Use clamps or other practical way to secure and support the workpiece to a stable platform.
Holding the work by hand or against your body is unstable and may lead to loss of control.
???Do not force tool. Use the correct tool for your application. 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 mea- sures 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'soperation. If damaged, have the tool serviced before using. Many acci- dents are caused by poorly maintained tools.
???Use only accessories that are recommended by the manufacturer for your 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, petroleum- based products, or any strong solvents to clean your tool. Following this rule will reduce the risk of loss of control and deterioration of the enclosure plastic.

ELECTRICAL CONNECTION
The belt 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).
Do not operate this tool on direct current (DO). A substantial voltage drop witl cause a loss of power and the motor will overheat. If your tool does not operate when plugged into an outlet,
The use of any extension cord will cause some loss of power. To keep the loss to a minimum 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 50 feet or less in
length. When working outdoors, use an extension cord that is suitable for outdoor use. This type of cord is designated with "WA" on the cord'sjacket.

Failure to do so could result in dust, shavings, chips, or loose particles being thrown in your eyes resulting in possible serious injury. If the operation is dusty, also wear a face or dust mask.
SELECTING SANDING BELTS
Selecting the correct size and type of sanding belt is an important step in achieving a high quality sanded finish. Aluminum oxide, silicon carbide, and other synthetic abrasives are best for power sanding.
In general, when sanding, coarse grit removes the most material and fine grit produces the best finish. The condition of the surface to be sanded determines which grit will do the best job. If the surface is rough, start with a coarse grit and sand until the surface is uniform. Then use medium grit to remove scratches left by the coarser grit. Finally, use finer grit for finishing the surface. Always continue sanding with each grit until the surface is uniform.
USING SANDING BELTS

Install the sanding belt.
A CAUTION: If the sanding belt is not a bidirectional belt, ensure that the arrow inside the belt is pointing in the direction of the rotation (clockwise when looking into the open side of the sander). Installing unidirectional sanding belts backwards can create a hazardous condition.

HELPFUL TIPS
???If the sanding belt slips or does not track while sand- ing, you may be applying too much pressure. When this occurs, remove the sander from the workpiece. If you properly adjust the belt tracking, the sanding belt wilt return to its normal and correct position on the drive roller and front roller.
???Use a coarser sanding belt for heavy sanding, not heavy pressure. The weight of the tool is sufficient to provide adequate pressure at the correct location.
???The front roller of the sander is not designed for con- tour sanding. Sanding on the front roller could cause irregularity in the sanding belt tracking.

GENERAL
Only the parts shown on the parts list are intended to be repaired or replaced by the customer. All other parts are 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 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, carbon dust, etc.
dt_ WARNING: Do not at any time let brake fluids, gasoline,
oils, etc. come in contact with plastic parts. They contain chemicals that can damage, weaken, or destroy plastic.
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 recommend 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 using compressed air.
_ 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. Failure to do so could result in possible serious injury.
LUBRICATION
All the bearings in this tool are lubricated with a sufficient amount of high grade lubricant for the life of the tool under normal operating conditions. Therefore, no further lubrication is required.
