Intended use
The tool is intended for impact drilling in brick, concrete
and stone as well as 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.

SPECIFIC SAFETY RULES
GEB003-2
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to hammer drill safety rules. If you use this power
tool unsafely or incorrectly, you can suffer serious
personal injury.
1.
Wear ear protectors with impact drills. 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. Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
5. Hold the tool firmly with both hands.
6. Keep hands away from rotating parts.
7. Do not leave the tool running. Operate the tool
only when hand-held.
8. Do not touch the bit or the workpiece immedi-
ately after operation; they may be extremely hot
and could burn your skin.
9. 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.
