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, fire, and/or severe 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 the work area clean and well-lit.
   Cluttered or dark areas invite accidents.
   b) 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.
   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 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.
   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.
   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.
   The use of an RCD reduces the risk of electric shock.

3. Personal safety
   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 influence of drugs, alcohol, or medication.
   A moment of inattention while operating power tools may result in serious personal injury.
   b) 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.
   c) Prevent unintentional starting. Ensure the switch is in the off position before connecting to a 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.
   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.
   e) Do not overreach. Keep proper footing and balance at all times.
   This enables better 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 long hair can be caught in moving parts.
   g) 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
   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 at 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 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.
   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. 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.
   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 different from those intended could result in a hazardous situation.

5. 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 fire.
   c) 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 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, flush with water. If liquid contacts the eyes, additionally seek medical help.
   Liquid ejected from the battery may cause irritation or burns.

6. Service
   a) Have your power tool serviced by a qualified 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.

CORDLESS 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 power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring.
   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. Do not allow foreign matter to enter the hole for connecting the rechargeable battery.

2. Never disassemble the rechargeable battery and charger.

3. Never short-circuit the rechargeable battery.
   Shortcircuiting the battery will cause a great electric current and overheating. It results in burn or damage to the battery.

4. Do not dispose of the battery in fi re. If the battery is burnt, it may explode.

5. When using this unit continuously, the unit may overheat, leading to damage in the motor and switch. Please leave it without using it for approximately 15 minutes.

6. Do not insert objects into the air ventilation slots of the charger. Inserting metal objects or inflammables into the charger air ventilation slots will result in electrical shock hazards or damaged chargers.

7. Bring the battery to the shop from which it was purchased as soon as the post-charging battery life becomes too short for practical use. Do not dispose of the exhausted battery.

8. 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.

9. Ensure that the power switch is in the OFF position. If the battery is installed while the power switch is in the ON position, the power tool will start operating immediately, which could cause a serious accident.

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

11. 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.

12. 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.

13. Make sure that the battery is installed firmly. If it is at all lost it could come off and cause an accident.

14. To prevent accidents, make sure to turn the switch off and pull out the battery before changing accessories, storing, carrying or when not using the tools.

15. Mounting the drill bit
    ○ To prevent accidents, make sure to turn the switch off and pull out the battery.
    ○ 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.
    ○ Check the latching by pulling on the drill bit.

16. Operate the change lever only when the motor is at a full stop. Operating the change lever while the motor is running may cause the tip tool to unexpectedly rotate and result in an accident. (Fig. 7)

17. Rotation + hammering
    When the drill bit touches the construction iron bar, the bit will stop immediately and the rotary hammer will react to revolve. Therefore firmly tighten the side handle, and hold the body handle and side handles.

18. Rotation only
    ○ To drill wood or metal material using the drill chuck and chuck adapter (optional accessories).
    ○ Application of force more than necessary will not only expedite the work at all, but will deteriorate the tip edge of the drill bit and reduce the service life of the rotary hammer addition.
    ○ Drill bits may snap off while withdrawing the rotary hammer from the drilled hole. For withdrawing, it is important to use a pushing motion.
    ○ Do not attempt to drill anchor holes or holes in concrete with the machine set in the rotation-only function.
    ○ Do not attempt to use the rotary hammer in the rotation and striking mode with the drill chuck and chuck adapter attached. This would seriously shorten the service life of every component of the machine.

19. Selecting the Power / Save mode
    ○ The hammering force of the hammer can be increased or decreased to conform with intended usage, by operating the shift knob as per Fig. 10. Adjust the force to match the usage intended.
    ○ Do not drill holes in wood with the “SAVE“ mode. There is a likelihood that the motor will burn out because it can easily lock up due to the low power.

20. Do not look directly into the light. Such actions could result in eye injury.

21.  To prevent the battery power consumption caused by forgetting to turn off the LED light, the light goes off automatically in about 15 minutes.
