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.

1) 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.

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.

f) 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.

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 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.

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) 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 dust

collection 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.

c) 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.

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. 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.

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 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.

5) 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.

SPECIFIC SAFETY RULES

• Wear ear protectors with impact drills. Exposure to noise can cause hearing loss.

• Use auxiliary handles supplied with the tool. Loss of control can cause personal injury.

• Hold power tools by insulated gripping surfaces when performing an operation

where the cutting tool may contact hidden wiring or its own cord. Contact with a

"live" wire will make exposed metal parts of the tool "live" and shock the operator.

• Use clamps or another practical way to secure and support the work piece to a

stable platform. Holding the work by hand or against your body leaves it unstable and

may lead to loss of control.

• When not in use, place tool on its side on a stable surface where it will not cause a

tripping or falling hazard. Some tools with large battery packs will stand upright but
may be easily knocked over.

• Do not operate this tool for long periods of time. Vibration caused by the operating

action of this tool may cause permanent injury to fingers, hands, and arms. Use gloves
to provide extra cushion, take frequent rest periods, and limit daily time of use.

• Keep your hair, clothing, and gloves away from air vents. Air vents often cover

moving parts in which these items can be caught.

• Hammer bits and tools get hot during operation. Wear gloves when touching them.

WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety

glasses. Also use face or dust mask if drilling operation is dusty. ALWAYS WEAR
CERTIFIED SAFETY EQUIPMENT:

• ANSI Z87.1 eye protection (CAN/CPA Z94.3),

• ANSI S12.6 (S3.19) hearing protection,

• NOSH/OSHA respiratory protection.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and

other construction activities contains chemicals known to the State of California
to cause cancer, birth defects or other reproductive harm. Some examples of
these chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry products, and

• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of
work. To reduce your exposure to these chemicals: work in a well ventilated area, and
work with approved safety equipment, such as those dust masks that are specially
designed to filter out microscopic particles.

• Avoid prolonged contact with dust from power sanding, sawing, grinding,

90552583 KR520HD KR550HD 6/16/09 11:11 AM Page 3

drilling, and other construction activities. Wear protective clothing and wash
exposed areas with soap and water.Allowing dust to get into your mouth, eyes, or lay

on the skin may promote absorption of harmful chemicals.

WARNING: Use of this tool can generate and/or disperse dust, which may cause

serious and permanent respiratory or other injury. Always use NOSH/OSHA approved

respiratory protection appropriate for the dust exposure. Direct particles away from face
and body.
