brick, concrete and stone as well as for chiselling work.
It is also suitable for drilling without impact in wood,

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 refer-
ence.
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 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 opera-
tion.
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 some-
one 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.
