REFERENCE.
WARNING
Work Area Safety
■ Keep work area clean and well lit. Cluttered or dark areas
invite accidents.
■ Do not operate power tools in explosive atmospheres, such
as in the presence of ammable liquids, gasses or dust.
Power tools create sparks which may ignite the dust or
fumes.
■ Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
Electrical Safety
■ 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.
■ Do not expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
Personal Safety
■ 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 inuence of drugs,
alcohol or medication. A moment of inattention white
operating power tools may result in serious personal injury.
■ Use personal protective equipment. Always wear eye

SAFETY INFORMATION
protection. Protective equipment such as dust mask,
nonslip safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal injuries.
■ 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 nger on the switch or energising power
tools that have the switch on invites accidents.
■ 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.
■ Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.

Keep your hair, clothing and gloves away from moving
parts. Loose clothes, jewellery or long hair can be caught in
moving parts.
■ 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
■ Recharge only with the charger specied by the
manufacturer. A charger that is suitable for one type of
battery pack may create a risk of re when used with
another battery pack.
