WARNING! Read and understand all instructions. Failure to follow all instructions listed below may result in serious personal injury.

WARNING! When using electric tools, machines, or equipment, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and personal injury. Completely read the manual before proceeding to use this tool. KEEP THESE INSTRUCTIONS.

CALIFORNIA PROP 65WARNING: 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 with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. For more information go to www.P65WARNINGs.ca.gov.



  • 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 that may ignite dust or fumes.
  • Keep bystanders, children, and visitors away while operating a power tool.
  • Distractions can cause you to lose control. Protect others in the work area from debris such as chips and sparks. Provide barriers or shields as needed.


  • Double Insulated tools are equipped with a polarized plug. This power 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 plugin anyway. 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.
  • Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
  • Handle the cord carefully. 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 with a qualified professional. Damaged cords increase the risk of electric shock.
  • When operating a power tool outside, use an outdoor extensions cord marked “W-A” or “W”. These cords are rated for outdoor use and reduce the risk of electric shock.


  • Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use tools while tired or under the influence of drugs, alcohol, or medication. A moment of inattentiveness while operating power tools may result in serious personal injury.
  • Dress properly. Do not wear loose clothing or jewelry. Pull long hair up and away from the face. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
  • Avoid accidental starting. Be sure the switch is off before plugging in. Carrying tools with your finger on the switch or plugging in tools with the switch ON invites accidents.
  • Remove adjusting keys before turning the tool on. A wrench or a 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 enable better control of the tool in unexpected situations.
  • Use safety equipment. Always wear eye protection. Dust masks, non-skid safety shoes, hard hats, or hearing protection should be used for appropriate conditions.POWER TOOL USE AND CARE
  • Use clamps or another practical way to secure and support the work piece 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 a tool if the 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 preventive 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 accessories sharp and clean. Properly maintained tools with sharp cutting edges are less likely to bind and are easier to control. Do not use a damaged tool. Tag damaged tools “Do Not Use” until repaired.
  • Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool’s 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.


  • Ensure the switch is in the off position before inserting the battery pack. Inserting the battery pack into power tools that have the switch ON may cause an accident.
  • Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
  • Use power tools only with specifically designed battery packs. Use of any other battery packs may create a risk of injury or fire.
  • When the battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the terminals together may cause burns or a fire.a. Do not use the tool in wet or damp conditions.b. Always keep the work area free of tripping hazards.c. When using the tool, always ensure you are wearing protective safety equipment including safety glasses/goggles, earplugs, damask, and other protective clothing including gloves and apron.
