WHEN USING ELECTRIC TOOLS, ALL THE SAFETY INSTRUCTIONS
SHOULD ALWAYS BE OBSERVED TO REDUCE THE RISK OF FIRE ,
ELECTRIC SHOCK AND PERSONAL INJURY BEFORE ATTEMPTING TO
OPERATE THE TOOL, PLEASE READ ALL THE INSTRUCTIONS AND SAVE IT
FOR FURTHER REFERENCE
General Power Tool Safety Warnings - 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. 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.
General Power Tool Safety Warnings - 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.
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.

General Power Tool Safety Warnings - 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 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.
c) 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 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) 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 jewelry. Keep your hair and
clothing away from moving parts. Loose clothes, jewelry 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 dust collection
can reduce dust-related hazards.
h) Don't neglect tool security principles because you use tools too often. A
careless action can cause severe injury within a fraction of a second.
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.
c) Disconnect the plug from the power source and/or remove the battery pack, if

5
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.
d) 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.
e) 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
tools operation. If damaged, have the power tool repaired before use. Many
accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories, tool bits, etc., under these instructions,
considering 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.
h) Keep handles and grasping surfaces dry, clean and free from oil and grease.
Slippery handles and grasping surfaces do not allow for safe handling and control
of the tool in unexpected situations.
Service
a) Have your power tool serviced by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.
