Safety

General power tool safety warnings
Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference. The term power tool in the warnings refers to your mains operated (corded) power tool or battery operated cordless power tool.

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

Electrical safety
Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed grounded power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.

• 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.
• Do not 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 for carrying, pulling or unplugging the power tool.
• Keep cord away from heat, oil, sharp edges or moving parts.
• Damaged or entangled cords increase the risk of electric shock.
• When operating a power tool outdoors, use an extension cord suitable for outdoor use.
• Use of a cord suitable for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply.
• Use of an RCD reduces 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 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.
