Safety Instructions
General Power Tool Safety Warnings
WARNING
Read all safety warnings, instruc-
tions, illustrations and specifica-
tions provided with this power tool. Failure to follow all in-
structions listed below 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 (cord-
less) power tool.
Work area safety
u Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
u Do not operate power tools in explosive atmospheres,
such as in the presence of flammable liquids, gases or
dust. Power tools create sparks which may ignite the dust
or fumes.
u Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
Electrical safety
u 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.
u Avoid body contact with earthed or grounded sur-
faces, such as pipes, radiators, ranges and refrigerat-
ors. There is an increased risk of electric shock if your
body is earthed or grounded.
u Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of elec-
tric shock.
u Do not abuse the cord. Never use the cord for carry-
ing, 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.
u When operating a power tool outdoors, use an exten-
sion cord suitable for outdoor use. Use of a cord suit-
able for outdoor use reduces the risk of electric shock.
u If operating a power tool in a damp location is un-
avoidable, use a residual current device (RCD) protec-
ted supply. Use of an RCD reduces the risk of electric
shock.
Personal safety
u 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 inatten-
tion while operating power tools may result in serious per-
sonal injury.
u Use personal protective equipment. Always wear eye
protection. Protective equipment such as a dust mask,
non-skid safety shoes, hard hat or hearing protection
used for appropriate conditions will reduce personal in-
juries.
u 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 en-
ergising power tools that have the switch on invites acci-
dents.
u 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 in-
jury.
u Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
u Dress properly. Do not wear loose clothing or jew-
ellery. Keep your hair and clothing away from moving
parts. Loose clothes, jewellery or long hair can be caught
in moving parts.
