General Power Tool Safety Warnings

WARNING Read all safety warnings and all instructions.
Failuretofollow the warnings and instructions may result in electric shock, fire, and/orserious 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

1. Work area safety
   a) Keep work area clean and well lit. Cluttered or dark areas inviteaccidents.
   b) Do not operate power tools in explosive atmospheres, suchasinthepresence of flammable liquids, gases or dust. Power tools createsparkswhichmay ignite the dust or fumes.
   c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2. Electrical safety
   a) Power tool plugs must match the outlet. Never modify the pluginanyway.Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
   b) Avoid body contact with earthed or grounded surfaces, suchaspipes,radiators, ranges and refrigerators. There is an increased risk of electricshockif your body is earthed or grounded.
   c) Do not expose power tools to rain or wet conditions. Water enteringapower tool will increase the risk of electric shock.
   d) Do not abuse the cord. Never use the cord for carrying, pullingorunplugging the power tool. Keep cord away fromheat, oil, sharpedgesormoving parts. Damaged or entangled cords increase the risk of electric shock.
   e) When operating a power tool outdoors, use an extension cord suitableforoutdoor use. Using a cord suitable for outdoor use reduces the risk of electricshock.
   f) If operating a power tool in a damp location is unavoidable, usearesidual current device (RCD) protected supply. The use of an RCDreducestheriskofelectric shock.

3. Personal safety
   a) Stay alert, watch what you are doing, and use common sense whenoperatingapower tool. Do not use a power tool while you are tired or under theinfluenceofdrugs, alcohol, or medication. A moment of inattention while operatingpowertoolsmay result in serious personal injury.
   b) Use personal protective equipment. Always wear eye protection. Protectiveequipment such as dust masks, non-skid safety shoes, hard hats, or hearingprotection used for appropriate conditions will reduce personal injuries.
   c) Prevent unintentional starting. Ensure the switch is in the off- positionbeforeconnecting to the power source and/or battery pack, picking up, or carryingthe  tool. Carrying power tools with your finger on the switch or energizing power toolswiththe switch on invites accidents.
   d) Remove any adjusting key or wrench before turning the power tool on. Awrench or a key left attached to a rotating part of the power tool mayresult inpersonal injury.
   e) Do not overreach. Keep proper footing and balance at all times. Thisenablesbetter control of the power tool in unexpected situations.
   f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing,and gloves away from moving parts. Loose clothes, jewelry or longhair canbecaught in moving parts.
   g) If devices are provided for connecting dust extraction and collectionfacilities,ensure these are connected and properly used. The use of dust collectioncanreduce dust-related hazards.

4. Power tool use and care
   a) Do not force the power tool. Use the correct power tool for your application.Thecorrect power tool will do the job better and safer at the rate for whichit wasdesigned.
   b) Do not use the power tool if the switch does not turn on and off. Anypowertoolthat cannot be controlled with the switch is dangerous and must berepaired.
   c) Disconnect the plug from the power source and/or the batterypackfromthe power tool before making any adjustments, changing accessories, orstoring power tools. Such preventive safety measures reduce theriskof startingthe power tool accidentally.
   d) Store idle power tools out of the reach of children and do not allowpersonsunfamiliar with the power tool or these instructions to operate thepower tool. Power tools are dangerous in the hands of untrained users.
   e) Maintain power tools. Check for misalignment or binding of movingparts, breakage of parts, and any other condition that may affect the power tool’soperation. If damaged, have the power tool repaired before use. Poorlymaintainedpower tools cause many accidents.
   f) Keep cutting tools sharp and clean. Properly maintained cuttingtoolswithsharpedges are less likely to bind and are easier to control.
   g) Use the power tool, accessories and tool bits, etc., following theseinstructions, considering the working conditions and the work to be performed. Usingthepowertool for operations different from those intended could result in a hazardoussituation.
