Instruction Manual




  • 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 which may ignite the 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 plug in any way. 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 by a qualified professional. Damaged cords increase the risk of electric shock.
  • When operating a power tool outside, use 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 tool 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 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 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 mask, non- skid safety shoes, hard hat, or hearing protection should be used for appropriate conditions.


  • Use clamps or other 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 tool if 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 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, ear plugs, dust mask and other protective clothing including gloves and apron.

  • Operations such as grinding, wire brushing, polishing, or cutting off are not recommended to be performed with this power tool. Operations for which the power tool was not designed may create a hazard and cause personal injury.
  • Do not use accessories which are not specifically designed and recommended by the tool manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe operation.
  • The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their RATED SPEED can break and fly apart.
  • The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled.
  • The arbor size of wheels, flanges, backing pads or any other accessory must properly fit the spindle of the power tool. Accessories with arbor holes that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively, and may cause loss of control.
  • Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked wires. if power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute. Damaged accessories will normally break apart during this test time.
  • 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 eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtering out particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.
  • Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or of a broken accessory may fly away and cause injury beyond immediate area of operation.
  • Hold power tool by insulated gripping surfaces only, when performing an operation where the accessory may contact hidden wiring or its own cord. An accessory contacting a ″live″ wire may make exposed metal parts of the power tool ″live″ and shock the operator.
  • Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grab the surface and pull the power tool out of your control.
  • Do not run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the accessory into your body.
  • Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards.
  • Do not operate the power tool near flammable materials. Sparks could ignite these materials.
  • Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.
  • Maintain labels and nameplates on the tool. These carry important safety information.
