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

Concrete 16 mm (5/8")

Steel 13 mm (1/2")

Wood 24 mm (5/16")

GEA006-2

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 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

2

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.

Battery tool use and care

24. Recharge only with the charger specified by
the manufacturer. A charger that is suitable for

one type of battery pack may create a risk of fire
when used with another battery pack.

25. Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.

26. When 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 fire.

27. Under abusive conditions, liquid may be

ejected from the battery; avoid contact. If
contact accidentally occurs, flush with water.
If liquid contacts eyes, additionally seek
medical help. Liquid ejected from the battery may

cause irritation or burns.

Service

28. 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.

29. Follow instruction for lubricating and

changing accessories.

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

GEB046-2

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.

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

3

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 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 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.

previous page.
Set the action mode changing knob so that the pointer
points to the

symbol.

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.

• Always secure small workpieces in a vise or similar

hold-down device.
