4. Safety instructions

NOTE
The safety rules in section 4.1 contain all general safety rules for
power tools which, in accordance with the applicable standards,
require to be listed in the operating instructions. Accordingly, some
of the rules listed may not be relevant to this tool.

4.1 General Power Tool Safety Warnings

a) WARNING! Read all safety warnings and all instruc-
tions. Failure to follow the warnings and instructions 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.

4.1.1 Work area safety

a) Keep work area clean and well lit. Cluttered or dark areas
invite accidents.
b) Do not operate power tools in explosive atmospheres, such
as in the presence of flammable liquids, gases or dust. Pow-
er tools create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a pow-
er tool. Distractions can cause you to lose control.
4.1.2 Electrical safety
a) Power tool plugs must match the outlet. Never modify the
plug in any way. Do not use any adapter plugs with earth-
ed (grounded) power tools. Unmodified plugs and matching
outlets will reduce risk of electric shock.
b) 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.
c) Do not expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
d) 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 entan-
gled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension
cord suitable for outdoor use. Use of a cord suitable for out-
door use reduces the risk of electric shock.

f) 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.
4.1.3 Personal safety
a) 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.
b) Use personal protective equipment. Always wear eye pro-
tection. Protective equipment such as dust mask, non-skid safe-
ty shoes, hard hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the
off-position before connecting to power source and/or bat-
tery 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.
d) 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.
e) Do not overreach. Keep proper footing and balance at all
times. This enables better control of the power tool in unex-
pected situations.
f) 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.
g) If devices are provided for the connection of dust extrac-
tion and collection facilities, ensure these are connected
and properly used. Use of dust collection can reduce dust-
related hazards.
4.1.4 Power tool use and care
a) 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.
b) 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.
