Power supply
The tool should be connected only to a power supply
of the same voltage as indicated on the nameplate,
and can be operated on single-phase AC/DC supply.
They are double-insulated in accordance with Euro-
pean Standard and can, therefore, also be used from
sockets without earth wire.
For public low-voltage distribution systems of
between 220 V and 250 V
Switching operations of electric apparatus cause volt-
age fluctuations. The operation of this device under
unfavorable mains conditions can have adverse
effects to the operation of other equipment. With a
mains impedance equal or less than 0.32 Ohms it can
be presumed that there will be no negative effects.
The mains socket used for this device must be
protected with a fuse or protective circuit breaker
having slow tripping characteristics.
Safety hints
For your own safety, please refer to the enclosed
safety instructions.
ADDITIONAL SAFETY RULES
1. Wear a hard hat (safety helmet), safety glasses
and/or face shield. It is also highly recom-
mended that you wear a dust mask, ear pro-
tectors and thickly padded gloves.
2. Be sure the bit is secured in place before
operation.
3. 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.
4. In cold weather or when the tool has not been
used for a long time, let the tool warm up for
several minutes by operating it under no load.
This will loosen up the lubrication. Without
proper warm-up, hammering operation is dif-
ficult.

5. Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
6. Hold the tool firmly with both hands.
7. Keep hands away from moving parts.
8. Do not leave the tool running. Operate the tool
only when hand-held.
9. Do not point the tool at any one in the area
when operating. The bit could fly out and
injure someone seriously.
10. When chipping into walls, floors or wherever
"live" electrical wires may be encountered, DO
NOT TOUCH ANY METAL PARTS OF THE
TOOL!
Hold the tool by the insulated grasping sur-
faces to prevent electric shock if you chip into
a "live" wire.
11. Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.
SAVE THESE INSTRUCTIONS.
