GENERAL POWER TOOL SAFETY WARNINGS

WARNING

Read all safety warnings, instructions, illustrations and specifi cations provided with this power tool.
Failure to follow all instructions listed below may result in electric shock, fi re and/or serious injury

Save all warnings and instructions for future reference.

The term “power tool” in the warnings refers to your mainsoperated (corded) power tool or battery-operated (cordless)  power tool.

1. Work area safety

2. a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.

3. b) Do not operate power tools in explosive atmospheres, such as in the presence of fl ammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

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

5. Electrical safety

   • a) 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. nmodifi ed plugs and matching outlets will reduce risk of electric shock.
   • b) 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.
   • c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
   • d) 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. e) 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.
   • f) 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.

6. Personal safety

7. a) 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 infl uence of drugs, alcohol or medication.
   A moment of inattention while operating power tools may result in serious personal injury.

8. b) Use personal protective equipment. Always wear eye protection. Protective equipment such as adust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.

9. c) Prevent unintentional starting. Ensure the switch is in the off -position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your fi nger on the switch or energising power tools that have the switch on invites accidents.

10. d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

11. e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

12. f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.

13. g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.

14. h) Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

15. Power tool use and care

    • a) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.

    • b) Do not use the power tool if the switch does not turn it on and off . Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

    • c) Disconnect the plug from the power source and/ or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

    • d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.
      Power tools are dangerous in the hands of untrained users.

    • e) Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may aff ect the power toolʼs operation. If damaged, have the power tool repaired before use.
      Many accidents are caused by poorly maintained power tools.

    • f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

    • g) Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations diff erent from those intended could result in a hazardous situation.

    • h) Keep handles and grasping surfaces dry, clean
      and free from oil and grease.
      Slippery handles and grasping surfaces do not
      allow for safe handling and control of the tool in
      unexpected situations.

16. Battery tool use and care

    • a) Recharge only with the charger specifi ed by the manufacturer.
      A charger that is suitable for one type of battery pack may create a risk of fi re when used with another battery pack.

    • b) Use power tools only with specifi cally designated battery packs. Use of any other battery packs may create a risk of injury and fi re.

    • c) 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 battery terminals together may cause burns or a fi re.

    • d) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, fl ush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

    • e) Do not use a battery pack or tool that is damaged or modifi ed. Damaged or modifi ed batteries may exhibit unpredictable behaviour resulting in fi re, explosion or risk of injury.

    • f) Do not expose a battery pack or tool to fi re or excessive temperature. Exposure to fi re or temperature above 130°C mayn cause explosion.

    • g) Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specifi ed in the instructions. Charging improperly or at temperatures outside the specifi ed range may damage the battery and increase the risk of fire.

17. Service

    • a) Have your power tool serviced by a qualifi ed repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
    • b) Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.
