GENERAL POWER TOOL SAFETY WARNINGS
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.
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 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
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.
FPO
WARNING!
Some dust created by power sanding, sawing, grinding, drilling and other construction activities contains
chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these
chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement and other masonry products.
• 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.
FPO
WARNING!
This product may contain lead, phthalates or other chemicals known to cause cancer, birth defects and
other reproductive harm. Please wash your hands after use.
FPO
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 electric (corded) power tool or battery-operated
(cordless) power tool.

GENERAL POWER TOOL SAFETY WARNINGS
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.
• 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 energizing 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 these are
connected and properly used. Use of dust collection 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 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 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 and tool bits in accordance with these instructions and in the manner
intended for the particular type of power tool, taking into account the working conditions and the
work to be performed. Use of the power tool for operations other than those intended could be hazardous.
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.

warnings
• 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.
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 WARNINGS FOR SCREWING INTO WALLS
• Hold power tool by insulated gripping surfaces, when performing an operation where the cutting
accessory may contact hidden wiring. Cutting accessory contacting a “live” wire may make exposed metal
parts of the power tool “live” and could give the operator an electric shock.
• Use clamps or another practical way to secure and support the workpiece to a stable platform.
Holding the work by hand or against your body leaves it unstable and may lead to loss of control.
