GENERAL POWER TOOL SAFETY WARNINGS

WARNING

Read all safety warnings and all instructions.
Failure to follow the warnings and instructions 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 mains-operated (corded) power tool or battery-operated (cordless) power tool.

1. 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 fl ammable liquids, gases or dust.
     Power tools create sparks that may ignite dust or fumes.

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

2. 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 tools.
     Unmodifi ed plugs and matching outlets will reduce the risk of electric shock.

   • 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.

   • Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep the cord away from heat, oil, sharp edges or moving parts.
     Damaged or entangled cords increase the risk of electric shock.

   • When operating a power tool outdoors, use an extension cord suitable for outdoor use.
     The use of a cord suitable for outdoor use reduces the risk of electric shock.

   • If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply.
     The use of an RCD reduces the risk of electric shock.

3. 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 power tools may result in serious personal injury.

   • Use personal protective equipment. Always wear eye protection.
     Protective equipment such as dust masks, non-skid safety shoes, hard hats, or hearing protection used for appropriate conditions will reduce personal injuries.

   • Prevent unintentional starting. Ensure the switch is in the off position before connecting to the power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.

   • 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.
     Do not overreach. Keep proper footing and balance at all times.
     This enables 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 clothes, jewelry, or long hair can be caught in moving parts.

   • If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used.
     The use of dust collection can reduce dust-related hazards.

4. Power tool use and care

   • 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.

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

   • Disconnect the plug from the power source and/or the battery pack 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.

   • 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.

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

   • 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, 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 different from those intended could result in a hazardous situation.

5. Service

   • 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.

PRECAUTION
Keep children and infi rm persons away. When not in use, tools should be stored out of reach of children and infi rm persons.

ROTARY HAMMER SAFETY WARNINGS

1. Wear ear protectors
   Exposure to noise can cause hearing loss.

2. Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.

3. Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

ADDITIONAL SAFETY WARNINGS

1. Ensure that the power source to be utilized conforms to the power requirements specifi ed on the product nameplate.
   Ensure that the power switch is in the OFF position.

2. If the plug is connected to a receptacle while the power switch is in the ON position, the power tool will start operating immediately, which could cause a serious accident.

3. When the work area is removed from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable.

4. Do not touch the bit during or immediately after the operation. The bit becomes very hot during operation and could cause serious burns.

5. Before starting to break, chip or drill into a wall, floor, or ceiling, thoroughly confi rm that such items as electric cables or conduits are not buried inside.

6. Always hold the body handle and side handle of the power tool firmly. Otherwise, the counterforce produced may result in inaccurate and even dangerous operations.

7. Wear a dust mask.
   Do not inhale the harmful dust generated in drilling or chiseling operations. The dust can endanger the health of yourself and bystanders.

8. Mounting the tool

   • To prevent accidents, make sure to turn the switch off and disconnect the plug from the receptacle.
   • When using tools such as bull points, drill bits, etc., make sure to use the genuine parts designated by our company.
   • Clean the shank portion of the drill bit. Then smear the shank portion with the grease or machine oil.

9. The rotation speed cannot be changed by pressing the rotation speed selector switch while the motor is rotating. To change speeds, switch off the tool first.

10. RCD
    The use of a residual current device with a rated residual current of 30mA or less at all times is recommended.
