SPECIFICATIONS
• Due to our continuing program of research and devel-
opment, the specifications herein are subject to change
without notice.
• Note: Specifications may differ from country to country.
Intended use
The tool is intended for hammer drilling and drilling in
brick, concrete and stone.
It is also suitable for drilling without impact in wood,
metal, ceramic and plastic.
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
ENB002-1
1. Hold tools by insulated gripping surfaces when
performing an operation where the cutting tool
may contact hidden wiring or its own cord. Con-
tact with a “live” wire will make exposed metal
parts of the tool “live” and shock the operator.
2. Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
3. Hold the tool firmly with both hands. Always use
the side grip.
4. Keep hands away from moving parts.
5. Do not leave the tool running. Operate the tool
only when hand-held.
6. Do not touch the bit or the workpiece immedi-
ately after operation; they may be extremely hot
and could burn your skin.
SAVE THESE INSTRUCTIONS.
