General Power Tool Safety Warnings
WARNING Read all safety warnings and all
instructions. Failure to follow the warnings and instruc-
tions may result in electric shock, fire and/or serious
injury.
Save all warnings and instructions for future
reference.
The term “power tool” in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
Work area safety
1.
Keep work area clean and well lit. Cluttered or
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.
9. If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)
protected supply.
Use of an RCD reduces the risk
of electric shock.
10. Use of power supply via a RCD with a rated
residual current of 30 mA or less is always rec-
ommended.
Personal safety
11. 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.
12. Use personal protective equipment. Always wear
eye protection. Protective equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will
reduce personal injuries.
13. Prevent unintentional starting. Ensure the
switch is in the off-position before connecting to
power source and/or battery pack, picking up or
carrying the tool.
Carrying power tools with your
finger on the switch or energising power tools that
have the switch on invites accidents.
14. 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.
15. Do not overreach. Keep proper footing and bal-
ance at all times. This enables better control of the
power tool in unexpected situations.
16. 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.
17. If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used.
Use of
dust collection can reduce dust-related hazards.
Power tool use and care
18. 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.
19. 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.
20. 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.
21. Store idle power tools out of the reach of chil-
dren 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.
