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 conditions. 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 protection. Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal injuries.
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 plugging 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 balance 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
away from moving parts. Loose clothes, jewellery
or long hair can be caught in moving parts.
2
15. If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
these devices can reduce dust-related hazards.
Power tool use and care
16. Do not force the power tool. Use the correct
power tool for your application. The correct power
tool will do the job better and safer at the rate for
which it was designed.
17. Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must be
repaired.
18. Disconnect the plug from the power source and/
or the battery pack from the power tool before
making any adjustments, changing accessories,
or storing power tools. Such preventive safety
measures reduce the risk of starting the power tool
accidentally.
19. Store idle power tools out of the reach of children and do not allow persons unfamiliar with
the power tool or these instructions to operate
the power tool. Power tools are dangerous in the
hands of untrained users.
20. Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power
tools operation. If damaged, have the power tool
repaired before use. Many accidents are caused by
poorly maintained power tools.
21. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
22. Use the power tool, accessories and tool bits
etc. in accordance with these instructions and in
the manner intended for the particular type of
power tool, taking into account the working conditions and the work to be performed. Use of the
power tool for operations different from those
intended could result in a hazardous situation.
Service
23. Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
24. Follow instruction for lubricating and changing
accessories.
25. Keep handles dry, clean and free from oil and
grease.
