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.

The term “power tool” in the warnings refers to your mains-operated (corded)
power tool or battery-operated (cordless) power tool.

WORK AREA SAFETY

• Keep the 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.

ELECTRICAL SAFETY

• 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 the risk of electric shock.

• 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.

• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging
the power tool. Keep the 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 ground-fault
circuit interrupter (GFCI) protected supply. Use of a GFCI reduces 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 the tool while tired or under the influence of drugs,
alcohol, or medication. A moment of inattention while operating power tools

may result in serious personal injury.

• Use personal protective equipment. Always wear eye protection. Protective
equipment such as 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 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.

• 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.

• If devices are provided for the connection of dust extraction and collection
facilities, ensure that these are connected and properly used. Use of these

devices can reduce dust-related hazards.

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 more safely 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 the battery pack 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. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power tool’s
operation. 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.

• Use the power tool, accessories, 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.

SERVICE

• 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.

SAFETY GUIDELINES FOR IMPACT WRENCH

• Hold the tool by insulated gripping surfaces when performing an operation
where the cutting tool may contact hidden wiring or its own cord. A cutting

accessory contacting a “live” wire may make exposed metal parts of the power
tool “live” and could give the operator an electric shock.

• Check the socket carefully for wear, cracks or damage before installation.

• Hold the tool firmly with both hands.

• Always be sure you have a firm footing. Be sure no one is below you when

using the tool in high locations.

• Check the torque with a torque wrench. The proper fastening torque may
differ depending on the type or size of the bolt.

ADDITIONAL SAFETY INSTRUCTIONS FOR OPERATION

• Know your power tool. Read the Instruction Manual carefully. Learn the
applications and the specific potential hazards related to this tool. Following
this rule will reduce the risk of electric shock, fire or serious injury.

• Protect your hearing. Wear appropriate personal hearing protection during use.
Under some conditions, noise from this product may contribute to hearing loss.

• All visitors and bystanders must wear the same safety equipment as the
operator.

• Inspect the tool cords periodically, and if damaged, have them repaired by a
qualified service technician. Be aware of the cord location.
