General Power Tool Safety Warnings
Warning: Read all safety warnings and instructions. 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.
ruoy ot srefer sgninraw eht ni ”loot rewop“ mret ehT
mains-operated (corded) power tool or battery-operated (cordless)
power tools.
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 flammable liquids, gases 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.

16
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 influence of drugs, alcohol or medication. A moment of
inattention while operating power tools may result in serious personal
injury.
Electrical safety
Power tool plugs must match the outlet. Never modify the plug in any
way. Do not use any adapter plugs with grounded power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
Avoid body contact with grounded surfaces such as pipes, radiators,
ranges and refrigerators. There is an increased risk of electric shock if your
body is grounded.
Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
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.
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.
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.

17
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 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 finger on the switch or
energising power tools that have the switch on invites acciden
ts.
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.
Dress properly. Do not wear loose clothing or jewellery. Keep your hair
and clothing 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.

18
Power Tool Use And Care
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.
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.
Disconnect the plug from the power source and/or remove the battery
pack, if detachable, 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.
Store idle power tools out of the reach of children 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.
Maintain power tools and accessories. Check for misalignment or
binding of moving parts, breakage of parts and any other condition that
may affect the power tool's operatio
n.
If damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power tools.
Keep cutting tools sharp and clean. Properly maintained cutting tools
with sharp cutting edges are less likely to bind and are easier to control.

19
Battery tool use and care
Recharge only with the charger specified by the manufacturer. A charger
that is suitable for one type of battery pack may create a risk of fire when
used with another battery pack.
Use power tools only with specifically designated battery packs. Use of
any other battery packs may create a risk of injury and fire.
When battery pack is not in use, keep it away from other metal objects, like
paper clips, coins, keys, nails, screws or other small metal objects, that can
make a connection from
one terminal to another. Shorting the battery
terminals together may cause burns or a fire.
Under abusive conditions, liquid may be ejected from the battery; avoid
contact. If contact accidentally occurs, flush with water. If liquid contacts
eyes, additionally seek medical help. Liquid ejected from the battery may
cause irritation or burns.
Do not use a battery pack or tool that is damaged or modified. Damaged
or modified batteries may exhibit unpredictable behaviour resulting in
fire, explosion or risk of injury.
Use the p
ower tool, accessories and tool bits etc. in accordance with
these instructions, taking into account the working conditions and the
work to be performed. Use of the power tool for operations different from
those intended could result in a hazardous situation.

20
Do not expose a battery pack or tool to fire or excessive temperature.
Exposure to fire or temperature above 130 °C may cause explosion.
