Safety Information

• Read all safety warnings and all instructions. Failure to follow the warnings and instructions 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.
  • 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.
• 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 a power tool can result in serious personal injury.
  • Use personal protective equipment. Always wear eye protection when operating a power tool. Dust masks, non-slip safety footwear, hard hats, hearing protection and gloves are also required in many working conditions.
  • Prevent unintentional starting. Ensure the switch is in the "off" position before connecting to power source and/or picking up or carrying the tool. Carrying a power tool with your finger on the switch or energizing a power tool that is connected to the power source invites accidents.
• Remove adjusting keys or wrenches before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may cause personal injury.
• Do not overreach. Keep proper footing and balance at all times. This will enable better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothing, jewelry or long hair can be caught in moving parts.
• Use auxiliary handles provided. Use auxiliary handles or a work rest whenever possible. This will help prevent you from losing control of the power tool.
• Do not abuse the power tool. Never use the power tool for a purpose for which it was not designed. Do not use the power tool if it is damaged. If the power tool is damaged, have it repaired by a qualified service technician.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
• Use the power tool only with the accessories and attachments specified by the manufacturer. Use of any other accessories or attachments may result in serious personal injury.
• Store power tools in a safe place out of the reach of children and unauthorized personnel.
