GENERAL SAFETY INSTRUCTIONS
WARNING! Read all safety warnings and all instructions. Failure to follow the warning and instructions may
result in electric shock, fire and or serious injury.
Wear personal protective equipment. Depending on application, use face shield,
safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and
workshop apron capable of stopping small abrasive or workpiece fragments.
The eye protection must be capable of stopping flying debris generated by various operations. The dust mask
or respirator must be capable of filtrating particles generated by your operation. Prolonged exposure to high
intensity noise may cause hearing loss. 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/MSHA respiratory protection
1) WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or 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.
• Do not use in wet conditions.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose
control.
2) PERSONAL SAFETY
• 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.
• Prevent unintentional starting. Ensure the trigger is in the off position before connecting to air source, pic-
king up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools
that have the switch on invites accidents.
• Exposure to high noise levels can cause permanent, disabling hearing loss and other problems, such as
tinnitus (ringing, buzzing, whistling, or humming in the ears). Therefore, a risk assessment and the imple-
mentation of appropriate controls for these hazards are essential. Appropriate controls to reduce the risk
may include actions such as damping materials to prevent workpieces from ringing.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from
