IMPORTANT SAFETY INSTRUCTIONS
WARNING
Read and understand all instructions before using this product. Failure to follow all
instructions listed below may result in electric shock, re, and/or serious personal 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.
WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Donotoperatechainsawinexplosiveatmospheres,suchasinthepresenceofammable
liquids, gases, or dust. Chainsaws create sparks which may ignite the dust or fumes.
• Keep all children, bystanders, visitors, and animals out of the work area while starting or
cutting with the chainsaw. Distractions can cause you to lose control.
ELECTRICAL SAFETY
• 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 the chainsaw to rain or wet locations. Water entering a chainsaw will increase
the risk of electric shock.
• If operating a power tool in a damp location is unavoidable, use a residual current
device protected supply. Use of an RCD reduces the risk of electric shock.
• A battery-operated tool with integral batteries or a separate battery pack must be
rechargedonlywiththespeciedchargerforthebattery.A charger that may be suitable for
one type of battery may create a risk of re when used with another battery.
PERSONAL SAFETY
• Stay alert, watch what you are doing and use common sense when operating a chainsaw.
Donotuseachainsawwhileyouaretiredorundertheinuenceofdrugs,alcoholor
medication. A moment of inattention while operating chainsaws may result in serious personal
injury.
• Use safety equipment. Always wear eye protection. Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce
personal injuries.
• Avoid accidental starting. Ensure the switch is in the off-position before plugging in.
Carrying power tools with your nger on the switch or plugging in 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 chainsaw may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. This enables better control
of the chainsaw 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.

IMPORTANT SAFETY INSTRUCTIONS
• If devices are provided for the connection of dust extraction and collection facilities,
ensure these are connected and properly used. Use of these devices can reduce dust-
related hazards.
POWER TOOL USE AND CARE
• Do not force the chainsaw. Use the correct chainsaw for your application. The correct
chainsaw will do the job better and safer at the rate for which it was designed.
• Do not use the chainsaw if the switch does not turn it on and off. Any chainsaw that cannot
be controlled with the switch is dangerous and must be repaired.
• Disconnect 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 chainsaws out of the reach of children and do not allow persons unfamiliar
with the chainsaw or these instructions to operate the chainsaw. Chainsaws are dangerous
in the hands of untrained users.
• Maintain chainsaws. Check for misalignment or binding of moving parts, breakage of
parts and any other condition that may affect the chainsaw’s operation. If damaged, have
the chainsaw repaired before use. Many accidents are caused by poorly maintained chainsaws.
• 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 chainsaw, 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
chainsaw for operations different from those intended could result in a hazardous situation.
BATTERY USE AND CARE
• Ensure the switch is in the off position before inserting battery pack. Inserting the battery
pack into power tools that have the switch on invites accidents.
• Rechargeonlywiththechargerspeciedbythemanufacturer. A charger that is suitable for
one type of battery pack may create a risk of re when used with another battery pack.
• Usepowertoolsonlywithspecicallydesignatedbatterypacks. Use of any other battery
packs may create a risk of injury and re.
• 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 re.
• Under abusive conditions, liquid may be ejected from the battery; avoid contact. If
contactaccidentallyoccurs,ushwithwater.If liquid contacts eyes, additionally seek
medical help. Liquid ejected from the battery may cause irritation or burns.
SERVICE
• Haveyourchainsawservicedbyaqualiedrepairpersonusingonlyidentical
replacement parts. This will ensure that the safety of the chainsaw is maintained.

IMPORTANT SAFETY INSTRUCTIONS
CHAINSAW SAFETY WARNINGS
• Keep all parts of the body away from the saw chain when the chainsaw is operating.
Before you start the chainsaw, make sure the saw chain is not contacting anything. A
moment of inattention while operating chainsaws may cause entanglement of your clothing or
body with the saw chain.
• Always hold the chainsaw with your right hand on the rear handle and your left hand on
the front handle. Holding the chainsaw with a reversed hand conguration increases the risk of
personal injury and should never be done.
• Hold the chainsaw by insulated gripping surfaces only, because the saw chain may
contact hidden wiring. Saw chains contacting a “live” wire may make exposed metal parts of
the chainsaw “live” and could give the operator an electric shock.
• Always use two hands when operating the chainsaw. Contact of the guide-bar tip with any
object should be avoided.
• Tip contact may cause the guide bar to move suddenly upward and backward, which may
cause serious injury.
• Wear safety glasses and hearing protection. Further protective equipment for the head,
hands, legs, and feet is recommended. Adequate protective clothing will reduce personal
injury by ying debris or accidental contact with the saw chain.
• Do not operate a chainsaw in a tree. Operation of a chainsaw while up in a tree may result in
personal injury.
• Alwayskeepproperfootingandoperatethechainsawonlywhenstandingonxed,
secure and level surface. Slippery or unstable surfaces such as ladders may cause a loss of
balance or control of the chainsaw.
• When cutting a limb that is under tension, be alert for spring back. When the tension in
the wood bers is released, the spring loaded limb may strike the operator and/or throw the
chainsaw out of control.
• Use extreme caution when cutting brush and saplings. The slender material may catch the
saw chain and be whipped toward you or pull you off balance.
• Carry the chainsaw by the front handle with the chainsaw switched off and away from
your body. When transporting or storing the chainsaw always put on the scabbard. Proper
handling of the chainsaw will reduce the likelihood of accidental contact with the moving saw
chain.
• Follow instructions for lubricating, chain tensioning, and changing accessories.
Improperly tensioned or lubricated chain may either break or increase the chance for kickback.
• Keep handles dry, clean, and free from oil and grease. Greasy, oily handles are slippery
which can cause loss of control.
• Cut wood only. Do not use chainsaw for purposes not intended. For example: do not
use chainsaw for cutting plastic, masonry, or non-wood building materials. Use of the
chainsaw for operations different than intended could result in a hazardous situation.

W A R N I N G (PROPOSITION 65)
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.
Your risk of exposure to these chemicals 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 dust masks that are specically designed to lter out
microscopic particles.
CHILD SAFETY
Tragic accidents can occur if the operator is not aware of the presence of children.
• Keep children out of the working area and under the watchful care of a responsible adult.
• Do not allow children under the age of 18 to operate this chainsaw. Children who are 18
years of age and older must read and understand the operating instructions and safety
rules in this manual and must be trained and supervised by a parent.
• Stay alert, and turn the chainsaw off if a child or any other person enters the working area.
• Use extreme care when approaching blind corners, doorways, shrubs, trees, or other
objects that may obscure your view of a child who may run into the path of the chainsaw.

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 chainsaw user, you should take several steps to keep your cutting jobs free from accident or
injury.
Kickback is the result of tool misuse and/or incorrect operating procedures or conditions
and can be avoided by taking proper precautions as given below:
1.Maintainarmgrip,withthumbsandngersencirclingthechainsawhandles,withboth
hands on the saw and position your body and arm to allow you to resist kickback forces.
Kickback can be controlled by the operator, if proper precautions are taken. Do not let go of the
chainsaw.
2. Do not overreach and do not cut above shoulder height. This helps prevent unintended tip
contact and enables better control of the chainsaw in unexpected situations.
3.Onlyusereplacementbarsandchainsspeciedbythemanufacturer.Incorrect replacement
bars and chains may cause chain breakage and/or kickback.
4. Follow the manufacturer’s sharpening and maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to increased kickback.

IMPORTANT SAFETY INSTRUCTIONS
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 CHAINSAW 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 certied 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. When tested on the representative sample of chainsaws
below 3.8 c.i.d. specied 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.

OPERATION
STARTING AND STOPPING THE CHAINSAW
A. Starting the Chainsaw:
• Make sure chain tension is at desired setting. Refer to adjusting the chain tension in the
Care and Maintenance section of this manual.
• Make sure the bar nuts are tight on the bar cover.
• Make sure no objects or obstructions are in the immediate vicinity which could come in
contact with the bar and chain.
• Insert the battery into the chainsaw.
• Press in the safety lock. This makes the trigger operational.
• Press and hold the trigger, and keep it pressed for continued operation.
B. Stopping the Chainsaw
• Release the trigger.
• Upon release of the trigger, the safety lock will be automatically reset to the lock position.
• This chain saw is equipped with a mechanical chain brake which is designed to stop a
moving chain in a fraction of a second if kickback occurs, reducing the chances of severe
injury. To manually engage the chain brake push the chain brake forward. This action will
lock the chain from moving; to release the chain brake, pull the brake toward the handle.
This will reset the chain brake.

OPERATION
PREPARING FOR CUTTING
Proper grip on handles
See Safety Rules for appropriate safety equipment.
• Wear non-slip gloves for maximum grip and protection.
• Hold the saw rmly with both hands. Always keep your left hand on the front handle and
your right hand on the rear handle so that your body is to the left of the chain line.
• Maintain a proper grip on the saw whenever the motor is running. The ngers should
encircle the handle and the thumb is wrapped underneath. This grip is least likely to be
broken by a kickback or other sudden reaction of the saw. Any grip in which the thumb
and ngers are on the same side of the handle is dangerous because a slight kickback of
the saw can cause loss of control.
WARNING
DO NOT operate the trigger with your left hand and hold the front handle with your right hand.
Never allow any part of your body to be in the chain line while operating a saw. Never use a left-
handed (cross-handed) grip or any stance that would place your body or arm across the chain line.

19
OPERATION
PROPER CUTTING STANCE
• Balance your weight with both feet on solid ground.
• Keep left arm with elbow locked in a “straight arm” position to withstand any kickback
force.
• Keep your body to the left of the chain line.
• Keep your thumb on underside of front handle.
BASIC OPERATING/CUTTING PROCEDURES
Practice cutting a few small logs using the following technique to get the “feel” of using the saw
before you begin a major sawing operation.
• Take the proper stance in front of the wood.
• Press the safety lock in and squeeze the trigger, then release the safety lock and let the
chain accelerate to full speed before entering the cut.
• Begin cutting with the saw against the log.
• Keep the unit running the entire time you are cutting, maintain a steady speed.
• The chain will cut for you; exert only light downward pressure. Forcing the cut could
result in damage to the bar, chain, or motor.
• Release the trigger as soon as the cut is completed, allowing the chain to stop. If you run
the saw without a cutting load, unnecessary wear can occur to the chain, bar, and unit.
• Do not put pressure on the saw at the end of the cut.

OPERATION
REMOVING BUTTRESS ROOTS
A buttress root is a large root extending from the trunk of the tree above the ground. Remove
large buttress roots prior to felling. Make the horizontal cut into the buttress rst, followed by the
vertical cut. Remove the resulting loose section from the work area. Follow the correct tree felling
procedure as stated in Proper Procedure For Tree Felling after you have removed the large
buttress roots.
PROPER PROCEDURE FOR TREE FELLING
• Felling a tree — When bucking and felling operations are being performed by two or
more persons at the same time, the felling operation should be separated from the
bucking operation by a distance of at least twice the height of the tree being felled. Trees
should not be felled in a manner that would endanger any person, strike any utility line or
cause any property damage. If the tree does make contact with any utility line, the utility
company should be notied immediately.
• Operator should keep on the uphill side of terrain as the tree is likely to roll or slide after it
is felled.
• Pick your escape route (or routes in case the intended route is blocked). Clear the
immediate area around the tree and make sure there are no obstructions in your planned
path of retreat. Clear the path of safe retreat approximately 135° from the planned line of
fall.
• Consider the force and direction of the wind, the lean and balance of the tree, and the
location of large limbs. These things inuence the direction in which the tree will fall. Do
not try to fell a tree along a line different from its natural line of fall.
• Remove dirt, stones, loose bark, nails, staples, and wire from the tree where felling cuts
are to be made.
• Notched Undercut. Cut a notch about 1/3 the diameter of the trunk on the side of the tree.
Make the notch cuts so they intersect at a right angle to the line of fall. This notch should
be cleaned out to leave a straight line. To keep the weight of the wood off the saw, always
make the lower cut of the notch before the upper cut.
