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.
11. Avoid accidental starting. Ensure the switch is in
the off-position before plugging in.
Carrying
power tools with your finger on the switch or plug-
ging in power tools that have the switch on invites
accidents.
12. Remove any adjusting key or wrench before
turning the power tool on.
A wrench or a key left
attached to a rotating part of the power tool may
result in personal injury.
13. Do not overreach. Keep proper footing and bal-
ance at all times.
This enables better control of the
power tool in unexpected situations.
14. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing, and gloves
