GENERAL SAFETY RULES
^ WARNING: Read and understand all instructions.
Failure to follow all instructions listed below, may
result in electric shock, fire and/or serious personal
injury.
SAVE THESE INSTRUCTIONS
Work Area
■ Keep your work area clean and well lit. Cluttered
benches and dark areas invite accidents.
■ Do not operate power tools in explosive atmo
spheres, such as in the presence of flammable
liquids, gases, or dust. Power tools create sparks
which may ignite the dust or fumes.
■ Keep bystanders, children, and visitors away while
operating a power tool. Distractions can cause you
to lose control.
Electrical Safety
■ Do not abuse the cord. Never use the cord to carry
the charger. Keep cord away from heat, oil, sharp
edges, or moving parts. Replace damaged cords
immediately. Damaged cords may create a fire.
■ A battery operated tool with integral batteries or a
separate battery pack must be recharged only with
the specified charger for the battery. A charger that
may be suitable for one type of battery may create a
risk of fire when used with another battery. Use battery
only with charger listed.

■ Use battery operated tool only with specifically
designated battery pack. Use of any other batteries
may create a risk of fire. Use only with battery pack
listed.
Personal Safety
■ Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use tool while tired or under the influence of
drugs, alcohol, or medication. A moment of inatten
tion while operating power tools may result in serious
personal injury.
■ Dress properly. Do not wear loose clothing or
jewelry. Contain long hair. Keep your hair, clothing,
and gloves away from moving parts. Loose clothes,
jewelry, or long hair can be caught in moving parts.
■ Avoid accidental starting. Be sure switch is in the
locked or off position before inserting battery
pack. Carrying tools with your finger on the switch or
inserting the battery pack into a tool with the switch on,
invites accidents.
■ Remove adjusting keys or wrenches before turn
ing the tool on. A wrench or a key that is left attached
to a rotating part of the tool may result in personal
injury.
■ Do not overreach. Keep proper footing and bal
ance at all times. Proper footing and balance enable
better control of the tool in unexpected situations.
■ Use safety equipment. Always wear eye protection.
Dust mask, non-skid safety shoes, hard hat, or hearing
protection must be used for appropriate conditions.
GENERAL SAFETY RULES
Tool Use and Care
■ Use clamps or other practical way to secure and
support the workpiece to a stable platform. Holding
the work by hand or against your body is unstable and
may lead to loss of control.
■ Do not force tool. Use the correct tool for your
application. The correct tool will do the job better and
safer at the rate for which It is designed.
■ Do not use tool if switch does not turn it on or off.
A tool that cannot be controlled with the switch is
dangerous and must be repaired.
■ Disconnect battery pack from tool or place the switch
in the locked or off position before making any adjust
ments, changing accessories, or storing the tool. Such
preventive safety measures reduce risk of starting the tool
accidentally.
■ Store idle tools out of reach of children and other
untrained persons. Tools are dangerous in the hands
of untrained users.
■ 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
sparks, burns, or a fire,
Maintain tools with care. Keep cutting tools sharp
and clean. Properly maintained tools, with sharp
cutting edges are less likely to bind and are easier to
control.
Check for misalignment or binding of moving parts,
breakage of parts, and any other condition that may
affect the tool’s operation. If damaged, have the tool
serviced before using. Many accidents are caused by
poorly maintained tools.
Use only accessories that are recommended by
the manufacturer for your model. Accessories that
may be suitable for one tool, may create a risk of injury
when used on another tool.
Service
Tool service must be performed only by qualified
repair personnel. Service or maintenance performed
by unqualified personnel could result in a risk of injury.
When servicing a tool, use only identical replace
ment parts. Follow instructions in the Maintenance
section of this manual. Use of unauthorized parts or
failure to follow Maintenance Instructions may create a
risk of shock or injury.
SPECIFIC SAFETY RULES AND/OR SYMBOLS
Hold tool 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.
Additional Ruies For Safe Operation
■ Know your power tool. Read operator’s manual
carefully. Learn its applications and limitations, as
well as the specific potential hazards related to
this tool. Following this rule will reduce the risk of
electric shock, fire, or serious injury.
■ Make sure your extension cord is in good condi
tion. When using an extension cord, be sure to
use one heavy enough to carry the current your
product will draw. A wire gage size (A.W.G.) of at
least 16 is recommended for an extension cord
100 feet or less in length. A cord exceeding 100
feet is not recommended. If in doubt, use the next
heavier gage. The smaller the gage number, the
heavier the cord. An undersized cord will cause a
drop in line voltage resulting in loss of power and
overheating.
Important Rules for Battery Tools
■ Battery tools do not have to be plugged into an
electrical outlet; therefore, they are always in
operating condition. Be aware of possible hazards
when not using your battery tool or when chang-
ing accessories. Following this rule will reduce the
risk of electric shock, fire, or serious personal injury.
Do not place battery tools or their batteries near
fire or heat. They may explode. Following this rule
will reduce the risk of electric shock, fire, or serious
personal injury.
Do not charge battery tool in a damp or wet
location. Following this rule will reduce the risk of
electric shock, fire, or serious personal injury.
Your battery tool should be charged in a location
where the temperature is more than 50°F but less
than 100°F, Following this rule will reduce the risk of
electric shock, fire, or serious personal Injury.
Under extreme usage or temperature conditions,
battery leakage may occur. If liquid comes in
contact with your skin, wash immediately with
soap and water, then neutralize with lemon juice
or vinegar. If liquid gets into your eyes, flush them
with clean water for at least 10 minutes, then seek
immediate medical attention. Following this rule will
reduce the risk of serious personal Injury.
