Intendended use
The tool is intended for hammer drilling in brick, concrete
and stone as well as for chiselling work.
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 without
earth wire.

For your own safety, please refer to the enclosed safety
instructions.

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 per-
sonal 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 recom-
mended 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.
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.
