General safety rules
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
1. Work area
a. Keep work area clean and well lit.
Cluttered and dark areas invite accidents.
b. 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.
c. Keep children and bystanders away while operating
a power tool.
Distractions can cause you to lose control.
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
earthed (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 entangled 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 outdoor use reduces the risk of electric shock.
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 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.
c. 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.
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 unexpected 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
extraction and collection facilities, ensure these are
connected and properly used.
Use of these devices
can reduce dust related hazards.
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.
