GENERAL SAFETY RULES 

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 atmospheres, 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

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 your 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 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 inattention 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, clothing, and gloves away from moving parts.

Loose clothing, jewelry, or long 

hair can be caught in moving parts. Air vents cover moving parts and should be avoided.

•  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 acci
dents.

•  Remove adjusting keys or wrenches before turning the tool on.

A wrench or 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, non-skid safety 

shoes, hard hat, or hearing protection must be used for appropriate conditions.

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 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 the power source before making any adjustments,    

changing accessories, or storing the tool.

Such preventative safety measures reduce 

the risk of starting the tool accidentally.

•  Store idle tools out of 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 tools 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 your model.

Accessories that may be suitable for one tool, may become hazardous when used on

another tool.

Service

•  Tool service must be performed only by qualified repair personnel.

Service or

maintenance performed by unqualified personnel could 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 electric shock or injury.

Specific Safety Rules

•  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 tool "live" and shock the operator.

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 (CCA).

Your risk from these exposures varies, depending on how often you do this type of  
work. To reduce your 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.

•  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: Use of this tool can generate and/or disperse 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.

CAUTION: Wear appropriate hearing protection during use.

Under some 

conditions and duration of use, noise from this product may contribute to hearing loss.

First Aid Measures for Gel Components

If gel within the comfort grip becomes exposed and results in skin contact wash with soap
and water; for eye contact, flush with flowing water. If swallowed, seek medical attention.

KEY INFORMATION YOU SHOULD KNOW:

• Never operate the sander without a recommended sanding sheet properly

installed on the base.

• The hook and loop pad and individual bases are replaceable parts. If they become

worn, return the unit to a local service center for repair.

• Do not push down—let the sander do the work. 
• Extended drywall sanding is not recommended for this product.
