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) BATTERY TOOL USE AND CARE
a) 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.
b) Use power tools only with specifically designated battery packs. Use of any
other battery packs may create a risk of injury and fire.
c) 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.
d) 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.

6) 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.
Additional Specific Safety Rules for Cut-Out Tools
• 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 workpiece to a
stable platform. Holding the work by hand or against your body leaves it unstable and
may lead to loss of control.
WARNING: After changing bits or making any adjustments, make sure the collet nut is
securely tightened to avoid injury.
WARNING: Do not press spindle lock or collet lock buttons while motor is running. The
operator may lose control and drop the tool. Personal injury or serious tool damage may
result.
WARNING: Shut off all live electric circuits to any areas where cut outs will be made, to
avoid fire or serious personal injury.
CAUTION: Do not touch the bit or collet nut during or immediately after cutting material.
The bit and collet nut may be hot enough to burn bare skin.
• Do not run tool while carrying at your side. The spinning bit may become entangled
with clothing and injury may occur.
• Always wear eye protection. Dust mask and hearing protection must be used for
appropriate conditions. Using personal safety devices is recommended. WORK SAFE.
• Always operate the tool with the depth guide in place. The guide keeps the bit
from plunging too deeply through the material. A minimum of penetration should be
maintained to eliminate the danger of cutting into electric wiring.
• Do not use this tool with drill or screwdriver bits. This tool is not intended to be used
as a drill or screwdriver.
• Be sure your cutting bits are sharp and in good condition. Damaged bits can cause
the tool to jump, injuring the operator.
• Never touch the bit immediately after use. It may be extremely hot.
• Be sure that the motor has stopped completely before you lay the tool down. If the
cutter head is still spinning when the tool is layed down, it could cause injury or damage.
• Be sure that the bit is clear of the workpiece before starting motor. If the bit is in
contact with the workpiece when the motor starts it could make the tool jump, causing
damage or injury.
• If your tool fails to function properly, take it to an authorized service center. There
are no user serviceable parts inside this tool and it should only be opened by trained
service personnel.
WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety
glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR
CERTIFIED SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.
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 and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber (CCA).
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,
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 disburse dust, which may cause serious
and permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory
protection appropriate for the dust exposure. Direct particles away from face and body.
WARNING: Always wear proper personal hearing protection that conforms to
ANSI S12.6 (S3.19) during use. Under some conditions and duration of use, noise from
this product may contribute to hearing loss.
CAUTION: 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 on the battery pack but may be easily knocked over.

WARNING: Fire hazard. Do not store or carry battery so that metal
objects can contact exposed battery terminals. For example, do not
place battery in aprons, pockets, tool boxes, product kit boxes, drawers, etc., with loose
nails, screws, keys, etc. without battery cap. Transporting batteries can possibly cause
fires if the battery terminals inadvertently come in contact with conductive materials
such as keys, coins, hand tools and the like. The US Department of Transportation
Hazardous Material Regulations (HMR) actually prohibit transporting batteries in commerce
or on airplanes (i.e., packed in suitcases and carry-on luggage) UNLESS they are properly
protected from short circuits. So when transporting individual batteries, make sure that the
battery terminals are protected and well insulated from materials that could contact them
and cause a short circuit.
