Intended use
The tool is intended for hammer drilling and drilling in
brick, conorete 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.
GENERAL SAFETY RULES
GEA001-3
WARNING! Read all instructions. Failure to follow all
instructions listed below may result in electric shock, fire
and/or serious injury. The term “power tool” in all of the
warnings listed below refers to your mains-operated
(corded) power tool or battery-operated (cordless) power
tool.
SAVE THESE INSTRUCTIONS.
Work area safety
1.
Keep work area clean and well lit. Cluttered and
dark areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
3. Keep children and bystanders away while oper-
ating a power tool. Distractions can cause you to
lose control.
Electrical safety
4.
Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodified plugs and matching outlets will
reduce risk of electric shock.
5. Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
6. Do not expose power tools to rain or wet condi-
tions. Water entering a power tool will increase the
risk of electric shock.
7. Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords
increase the risk of electric shock.
8. When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the risk of
electric shock.
Personal safety
9.
Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under
the influence of drugs, alcohol or medication. A
moment of inattention while operating power tools
may result in serious personal injury.
10. Use safety equipment. Always wear eye protec-
tion. Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal inju-
ries.
