GENERAL SAFETY RULES

WARNING! Read all instructions. Failure to follow all

instructions listed below may result in electric shock, fire
and/or serious injury. The term "power tool" in all of the
warnings listed below refers to your mains-operated
(corded) power tool or battery-operated (cordless) power
tool.

SAVE THESE INSTRUCTIONS.

Work area safety

1. Keep work area clean and well lit. Cluttered and

dark areas invite accidents.

2. 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.

3. Keep children and bystanders away while
operating a power tool. Distractions can cause
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

surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of

electric shock if your body is earthed or grounded.

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.

Concrete 24 mm (15/16")

Core bit 54mm (2-1/8")

Steel 13 mm (1/2")

Wood 32 mm (1-1/4")

GEA001-3

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.

Personal Safety

9. 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.

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

11. Avoid accidental starting. Ensure the switch is
in the off-position before plugging in. Carrying
power tools with your finger on the switch or
plugging in power tools that have the switch on
invites accidents.

12. 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.

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

14. 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.

15. If devices are provided for the connection of

dust extraction and collection facilities,
ensure these are connected and properly used.

Use of these devices can reduce dust-related
hazards.

Power tool use and care

16. 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.

17. 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.

18. 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.

19. 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.

20. Maintain power tools. Check for misalignment

or binding of moving parts, breakage of parts
and any other condition that may affect the
power tools operation. If damaged, have the
power tool repaired before use. Many accidents

are caused by poorly maintained power tools.

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

22. Use the power tool, accessories and tool bits

etc. in accordance with these instructions and
in the manner intended for the particular type
of power tool, 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

23. 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.

24. Follow instruction for lubricating and

changing accessories.

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

GEB007-2

SPECIFIC SAFETY RULES

DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to rotary hammer safety rules. If you use this tool
unsafely or incorrectly, you can suffer serious
personal injury.

1. Wear ear protectors. Exposure to noise can

cause hearing loss.

2. Use auxiliary handles supplied with the tool.

Loss of control can cause personal injury.

3. Hold power tools by insulated gripping

surfaces when performing an operation where
the cutting tool may contact hidden wiring or
its own cord. Contact with a "live" wire will make

exposed metal parts of the tool "live" and shock
the operator.

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.

WARNING:

MISUSE or failure to follow the safety rules stated in
this instruction manual may cause serious personal
injury.

the tool is running under load. The tool will be
damaged.

• To avoid rapid wear on the mode change

mechanism, be sure that the action mode
changing knob is always positively located in one
of the three action mode positions.

Torque limiter

The torque limiter will actuate when a certain torque
level is reached. The motor will disengage from the
output shaft. When this happens, the bit will stop turning.

CAUTION:

• As soon as the torque limiter actuates, switch off

the tool immediately. This will help prevent
premature wear of the tool.

• Bits such as hole saw, which tend to pintch or

catch easily in the hole, are not appropriate for this
tool. This is because they will cause the torque
limiter to actuate too frequently.

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 a 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.

NOTE:

Eccentricity in the bit rotation may occur while operating
the tool with no load. The tool automatically centers itself
during operation. This does not affect the drilling
precision.

CAUTION:

• Never use "rotation with hammering" when the

quick change drill chuck is installed on the tool.
The quick change drill chuck 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.

• Always secure small workpieces in a vise or similar

hold-down device.
