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.
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 protec-
tors and thickly padded gloves.
2. Be sure the bit is secured in place before opera-
tion.
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 sev-
eral minutes by operating it under no load. This
will loosen up the lubrication. Without proper
warm-up, hammering operation is difficult.
5. Always be sure you have a firm footing. Be sure
no one is bellow 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.
