SAFETY INFORMATION
IMPORTANT
Read and understand all instructions. Failure to follow all instructions listed below may result in
electric shock, re, and/or serious personal injury.
WARNING
When using an cordless chain saw, basic safety precaution should be always followed to reduce the
risk of re, electric shock, and injury to persons, including the following:
• Do not start cutting until you have a clear work area, secure footing, and a planned retreat path
from the falling tree. Cluttered areas invite accidents.
• Keep all children, bystanders, visitors, and animals out of the work area while starting or cutting
with the chain saw.
• Do not operate chain saw in explosive atmospheres, such as in the presence of ammable liquids,
gases, or dust. Power tools create sparks which may ignite the dust or fumes.
• Wear snug tting clothing. Always wear heavy, long pants, overalls, jeans or chaps made of cut
resistant material or ones that contain cut resistant inserts. Wear non-slip safety footwear. Wear
non-slip heavy duty gloves to improve your grip and to protect your hands. Do not wear jewelry,
short pants, sandals, or go barefoot. Do not wear loose tting clothing, which could be drawn into
the motor or catch the chain or underbrush. Secure hair so it is above shoulder level.

SAFETY INFORMATION
• Heavy protective clothing may increase operator fatigue, which could lead to heat stroke. During
weather that is hot and humid, heavy work should be scheduled for early morning or late afternoon
hours when temperatures are cooler.
• Wear eye protection which is marked to comply with ANSI Z87.1 as well as hearing and head
protection when operating this equipment.
• Always be aware of what you are doing when using the chain saw. Use common sense. Do not
operate the chain saw when you are tired, ill, or under the inuence of alcohol, drugs, or
medication.
• Do not expose the chain saw to rain.
• Do not use the chain saw in damp or wet locations.
• Stay alert and pay attention to what you are doing. Use common sense when using this unit.
• Keep all parts of your body away from the saw chain when the unit is running.
• Always carry the chain saw by the front handle with the battery removed and the guide bar and saw
chain positioned to the rear.
• Never let anyone use your chain saw who has not received adequate instructions in its proper use.
• Before you start the unit, make sure the saw chain is not contacting any object.
• Stop the chain saw before setting it down.
• To avoid accidental starting, never carry the unit with your nger on the trigger switch.
• Maintain the unit with care. Keep the cutting edge sharp and clean for best performance and to
reduce the risk of injury. Follow instructions for lubricating and changing accessories.
• Keep handles dry, clean, and free of oil and grease.
• Use only Kobalt 40 V batteries.
• Do not dispose of batteries in a re, the cell may explode, check with local codes for possible
special disposal instruction.
• Do not open or mutilate the batteries; released electrolyte is corrosive and may cause damage to
the eyes or skin, and may be toxic if swallowed.
• Exercise care in handling battery in order not to short the battery with conducting material such as
rings, bracelets and keys. The battery or conductor may overheat and cause burns.
• Do not operate a chain saw with one hand. Use a rm grip with thumbs and ngers encircling the
chain saw handles. Serious injury to the operator, helpers, bystanders, or any combination of these
persons may result from one-handed operation. A chain saw is intended for two handed use.
• Avoid body contact with grounded surfaces such as metal pipes and wire fences. There is an
increased risk of electric shock if your body is grounded.
• Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely
assembled. The chain should slow to a stop when the trigger switch is released. If the chain
continues to turn after the trigger switch has been released, have the unit serviced by an authorized
service center.
• Check for damaged parts. Check for alignment of moving parts, binding of moving parts, breakage
of parts, mounting, and any other conditions that may affect its operation. A guard or other part that
is damaged should be properly repaired or replaced by an authorized service dealer unless
otherwise indicated elsewhere in this manual.
• All chain saw service, other than the items listed in the operation and maintenance sections, should
be performed by your authorized service center.
• Always maintain a proper stance.

SAFETY INFORMATION
• Remove the battery when not in use, before servicing, and when making adjustments and changing
attachments, such as saw chain and bar.
• Do not cut vines and/or small underbrush.
• Do not operate a chain saw in a tree, on a ladder, or scaffold; this is extremely dangerous.
Note: The size of the work area depends on the job being performed as well as the size tree or work
piece involved. For example, felling a tree requires a larger work area than making bucking cuts.
• Use extreme caution when cutting small size brush and saplings because the small material may
catch the saw chain and be whipped toward you or pull you off balance.
• When cutting a limb that is under tension, be alert for spring back so that you will not be struck
when the tension in the wood bers is released.
• Do not force the chain saw. The job can be performed better and safer at the rate for which it was
intended.
• Always use the right product for your application. The chain saw should be used for cutting wood
only. Never use the chain saw to cut plastic, masonry or non-wood building materials.
• Do not use the chain saw for purposes not intended.
• Store chain saw when not in use. Chain saw should be stored in a dry and high or locked area out
of the reach of children.
• Save these instructions. Refer to them frequently and use them to instruct others who may use this
tool. If you loan someone this tool, loan them these instructions also.
WARNING Proposition 65
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities
contain 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.
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 lter out microscopic particles.
Kickback
WARNING
Kickback may occur when the moving chain contacts an object at the upper portion of the tip of the
guide bar or when the wood closes in and pinches the saw chain in the cut. Contact at the upper
portion of the tip of the guide bar can cause the chain to dig into the object and stop the chain for an
instant. The result is a lightning fast reverse reaction which kicks the guide bar up and back toward
the operator. If the saw chain is pinched along the top of the guide bar, the guide bar can be driven
rapidly back toward the operator. Either of these reactions can cause loss of saw control which can
result in serious injury. Do not rely exclusively upon the safety devices built into the saw. As a chain
saw user, you should take several steps to keep your cutting jobs free from accident or injury.

SAFETY INFORMATION
The following precautions should be followed to minimize
kickback:
• Always grip the saw rmly with both hands. Place your
right hand on the rear handle and your left hand on the
front handle with your thumbs and ngers encircling
the chain saw handles. A rm grip together with a stiff
left arm will help you maintain control of the saw if
kickback occurs.
• Make sure that the area in which you are cutting is free
from obstructions. Do not let the nose of the guide bar
contact a log, branch, fence, or any other obstruction
that could be hit while you are operating the saw.
• Always cut with the unit running. Fully squeeze the
trigger switch and maintain cutting speed.
• Use only the replacement guide bars and low
kickback chains specied by the manufacturer for the
saw.
• With a basic understanding of kickback, you can
reduce or eliminate the element of surprise. Sudden
surprise contributes to accidents.
• Keep proper footing and balance at all times.
• Do not cut above shoulder height or overreach when
cutting.
• Follow the sharpening and maintenance instructions
for the saw chain.

SAFETY INFORMATION
• Push and Pull - This reaction force is always
opposite to the direction the chain is moving where
wood contact is made. Thus, the operator must be
ready to control the PULL when cutting on the bottom
edge of the bar, and PUSH when cutting along the top
edge.
Understanding your chain saw safety devices
Low kickback saw chain
The rakers (depth gauges) ahead of each cutter can
minimize the force of a kickback reaction by preventing
the cutters from digging in too deeply at the kickback
zone. Only use replacement chain that is equivalent to
original chain or has been certied as low kickback chain
per ANSI B175.1. Low kickback/skip tooth saw chain is a
chain that has met the kickback performance
requirements of ANSI B175.1 - 1991. (American National
Standard for Power Tools - Gasoline-Powered Chain
Saws-Safety Requirements) when tested on the
representative sample of chain saws below 3.8 c.i.d.
specied in ANSI B175.1 - 1991. As saw chains are
sharpened during their useful life, they lose some of the
low kickback qualities and extra caution should be used.
Service
Servicing requires extreme care and knowledge and should be performed only by a qualied service
technician. For service we suggest you return the product to your nearest AUTHORIZED SERVICE
CENTER for repair. When servicing, use only identical replacement parts.
