Intended use
The tool is intended for hammer drilling in brick, concrete
and stone as well as for chiselling work.
ENF002-1
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 double-insulated in accordance with European
Standard and can, therefore, also be used from sockets

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
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.
Work area safety
1. Keep work area clean and well lit. Cluttered or
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.

3
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 ground fault circuit
interrupter (GFCI) protected supply. Use of an
GFCI reduces the risk of electric shock.
Personal safety
10. 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.
11. 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.
12. 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.
13. 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.
14. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
15. 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.
16. 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
17. 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.
18. 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.
19. 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.
20. 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.
21. 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.
22. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
23. 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
24. 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.
25. Follow instruction for lubricating and
changing accessories.
26. Keep handles dry, clean and free from oil and
grease.
GEB007-5
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 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 or its own cord. Cutting accessory

4
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.

Set the change lever 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:
• When the bit begins to break through concrete or if
the bit strikes reinforcing rods embedded in
concrete, the tool may react dangerously. Maintain
good balance and safe footing while holding the
tool firmly with both hands to prevent dangerous
reaction.
