• Due to our continuing program of research and
development, the specifications herein are subject

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 Euro-
pean Standard and can, therefore, also be used from
sockets without earth wire.
Safety hints
For your own safety, please refer to enclosed the
safety instructions.
ADDITIONAL SAFETY RULES FOR
TOOL
ENB010-1
1. Hold tools by insulated gripping surfaces
when performing an operation where the cut-
ting 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.
2. Wear ear protectors when using the tool for
extended periods. Prolonged exposure to high
intensity noise can cause hearing loss.
3. Wear a hard hat (safety helmet), safety glasses
and/or face shield. It is also highly recom-
mended that you wear a dust mask and thickly
padded gloves.
4. Be sure the bit is secured in place before
operation.
5. 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.
6. 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.
7. Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
8. Hold the tool firmly with both hands.
9. Keep hands away from moving parts.
10. Do not leave the tool running. Operate the tool
only when hand-held.
11. Do not point the tool at any one in the area
when operating. The bit could fly out and
injure someone seriously.
12. Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.
