Additional Safety Information

WARNING: Never modify the power tool or any part of it.
Damage or personal injury couldresult.

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 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.
Additional Specific Safety Rules for Cut-Out Tools
• 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.
• Hold power tools by insulated gripping surfaces when
performing an operation where the cutting tool may
contact hidden wiring. Contact with a “live” wire will make
exposed metal parts of the tool “live” and shock theoperator.

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.
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.
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.
e ) Do not use a battery pack or tool that is damaged
or modified. Damaged or modified batteries may exhibit
unpredictable behavior resulting in fire, explosion or risk
ofinjury.
f ) Do not expose a battery pack or tool to fire or
excessive temperature. Exposure to fire or temperature
above 265°F (130°C) may causeexplosion.
g ) Follow all charging instructions and do not charge
the battery pack or tool outside the temperature range
specified in the instructions. Charging improperly or at
temperatures outside the specified range may damage the
battery and increase the risk offire.
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.
b ) Never service damaged battery packs. Service of
battery packs should only be performed by the manufacturer or
authorized serviceproviders.

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.
• Always follow the bit manufacturer’s speed
recommendations as some bit designs require specific
speeds for safety or performance. If you are unsure of the
proper speed or are experiencing any type of problem, contact
the bitmanufacturer.
• 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 laid 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.
• Air vents often cover moving parts and should be
avoided. Loose clothes, jewelry or long hair can be caught in
movingparts.
