instructions for future reference.

In observance of European Directive

2002/96/EC on waste electric and electronic equipment and its implementation in accordance with national law, electric equipment that have reached the end of their life must be collected separately and returned to an environmentally compatible recycling facility.

ENE043-1

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated

(cordless) power tool.

Work area safety

1.

2.

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

flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

The tool is intended for hammer drilling and drilling in brick, concrete and stone as well as for chiselling work.

3. Keep children and bystanders away while

operating a power tool. Distractions can cause

It is also suitable for drilling without impact in wood, metal, ceramic and plastic.

ENF002-2

Power supply

The tool should be connected only to a power supply of the same voltage as indicated on the nameplate, and can only be operated on single-phase AC supply. They are you to lose control.

Electrical safety

4. 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. Unmodified plugs and matching outlets will reduce risk of electric shock.

5. Avoid body contact with earthed or grounded double-insulated and can, therefore, also be used from sockets without earth wire. surfaces such as pipes, radiators, ranges and

refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

2

6. Do not expose power tools to rain or wet

conditions. Water entering a power tool will increase the risk of electric shock.

7. 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.

8. 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.

9. 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.

10. Use of power supply via a RCD with a rated residual current of 30mA or less is always recommended.

Personal safety

11. 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.

12. Use personal protective equipment. Always

wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

13. 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 finger on the switch or energising power tools that have the switch on invites accidents.

14. 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.

15. Do not overreach. Keep proper footing and

balance at all times. This enables better control of the power tool in unexpected situations.

16. Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing, and gloves

away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.

17. 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.

Power tool use and care

18. 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.

19. 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.

20. 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.

21. 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.

22. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the

power tool repaired before use. Many accidents are caused by poorly maintained power tools.

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

24. 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.

Service

25. 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.

26. Follow instruction for lubricating and changing accessories.

27. Keep handles dry, clean and free from oil and grease.

GEB007-7

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

3

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.

4. Wear a hard hat (safety helmet), safety glasses and/or face shield. Ordinary eye or sun glasses are NOT safety glasses. It is also highly recommended that you wear a dust mask and thickly padded gloves.

5. Be sure the bit is secured in place before operation.

6. Under normal operation, the tool is designed to produce vibration. The screws can come loose easily, causing a breakdown or accident.

Check tightness of screws carefully before operation.

7. In cold weather or when the tool has not been used for a long time, let the tool warm up for a while by operating it under no load. This will loosen up the lubrication. Without proper warm-up, hammering operation is difficult.

8. Always be sure you have a firm footing.

Be sure no one is below when using the tool in high locations.

9. Hold the tool firmly with both hands.

10. Keep hands away from moving parts.

11. Do not leave the tool running. Operate the tool only when hand-held.

12. Do not point the tool at any one in the area when operating. The bit could fly out and injure someone seriously.

13. Do not touch the bit or parts close to the bit immediately after operation; they may be extremely hot and could burn your skin.

14. Some material contains chemicals which may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.

SAVE THESE INSTRUCTIONS.

Chipping/Scaling/Demolition

010167

Set the action mode changing knob to the symbol.

Position the bit at the desired location for the hole, then pull the switch trigger.

Do not force the tool. Light pressure gives best results.

Keep the tool in position and prevent it from slipping away from the hole.

Do not apply more pressure when the hole becomes clogged with chips or particles. Instead, run the tool at an idle, then remove the bit partially from the hole. By repeating this several times, the hole will be cleaned out and normal drilling may be resumed.

CAUTION:

•

There is tremendous and sudden twisting force exerted on the tool/bit at the time of hole break-through, when the hole becomes clogged with chips and particles, or when striking reinforcing rods embedded in the concrete. Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations. Failure to do so may result in the loss of control of the tool and potentially severe injury.

1. Drill chuck assembly

010157

Use the optional drill chuck assembly. When installing it, refer to "Installing or removing drill bit" described on the previous page.

Set the action mode changing knob to the symbol.

You can drill up to 13 mm diameter in metal and up to 32 mm diameter in wood.

•

•

•

•

CAUTION:

Never use "rotation with hammering" when the drill chuck assembly is installed on the tool. The drill chuck assembly may be damaged.

Also, the drill chuck will come off when reversing the tool.

Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pressure will only serve to damage the tip of your bit, decrease the tool performance and shorten the service life of the tool.

There is a tremendous twisting force exerted on the tool/bit at the time of hole breakthrough. Hold the tool firmly and exert care when the bit begins to break through the workpiece.

A stuck bit can be removed simply by setting the reversing switch to reverse rotation in order to back out. However, the tool may back out abruptly if you do not hold it firmly.
