SAVE ALL WARNINGS AND INSTRUCTIONS
FOR FUTURE REFERENCE
1) WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Keep children and bystanders away while operating a power tool. Distractions can
cause you to lose control.
c) Ensure the workplace is well ventilated. Exposure to dust at a poorly ventilated
workplace may result in damage to the health.
2) ELECTRICAL SAFETY
a) Avoid body contact with earthed or grounded surfaces such as pipes, radiators,
ranges and refrigerators. There is an increased risk of electric shock if your body is
earthed or grounded.
3) PERSONAL SAFETY
a) Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use a power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of inattention while operating power tools
may result in serious personal injury.
b) Use personal protective equipment. Always wear eye protection. Protective
equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce personal injuries.
c) Do not overreach. Keep proper footing and balance at all times. This enables
better control of the power tool in unexpected situations.
d) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing
and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught
in moving parts.
4) POWER TOOL USE AND CARE
a) Do not force the power tool. Use the correct power tool for your application. The
correct power tool will do the job better and safer at the rate for which it was designed.

dealer, call 1-800-4-D
• Do not use the tool in damp or wet conditions.
• Do not allow to be used as a toy. Close attention is necessary when used by or near children.
• Use only as described in this manual. Use only manufacturer's recommended attachments.
• Do not put any object into openings. Do not use with any opening blocked; keep free of lint,
hair and anything that may reduce air flow.
• Keep hair, loose clothing, fingers and all parts of body away from openings and moving parts.
• Do not use to pick up flammable or combustible liquids, such as gasoline, or use in areas
where they may be present.
• This appliance collects a significant percentage of, but not all, the dust generated.
WARNING: ALWAYS USE SAFETY GLASSES. Everyday eyeglasses are NOT safety
glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS wear certified safety
equipment:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3).
• ANSI S12.6 (S3.19) hearing protection.
• NIOSH/OSHA respiratory protection.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to the State of California 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.
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 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: Before beginning the work, check to determine the hazard classification
of the dust produced. Use an industrial dust extractor vacuum of the appropriate
official approved safety class and in compliance with your local dust hazard control
regulations.
WARNING: Always wear proper personal hearing protection. Under some conditions
and duration of use, noise from this product may contribute to hearing loss.
