GENERAL PRODUCT SAFETY WARNINGS
WARNING! Read all safety warnings, instructions,
illustrations and specifications provided with this
power tool. Failure to follow all instructions listed below
may result in electric shock, re, 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) product or battery-operated (cordless)
product.
WORK AREA SAFETY
■Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
■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.
■Keep children and bystanders away while operating
a power tool. Distractions can cause you to lose
control.
ELECTRICAL SAFETY
■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.
■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 power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
■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.
■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.
■If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk of
electric shock.
PERSONAL SAFETY
■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.
■Use personal protective equipment. Always wear
eye protection. Protective equipment such as a dust
mask, non-skid safety shoes, hard hat or hearing
protection used for appropriate conditions will reduce
personal injuries.
■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.
■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.
■Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
■Dress properly. Do not wear loose clothing or
jewellery. Keep your hair and clothing away from
moving parts. Loose clothes, jewellery or long hair can
be caught in moving parts.
■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.
■Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
POWER TOOL USE AND CARE
■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.
■Do not use the power tool if the switch does not turn
it on and off. Any power tool that cannot be controlled
with switch is dangerous and must be repaired.
■Disconnect the plug from the power source and/
or remove the battery pack, if detachable, from

3
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 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.
■Maintain power tools and accessories. 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.
■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 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.
■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.
BATTERY TOOL USE AND CARE
■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.
■Use power tools only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire.
■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.
■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.
■Do not use a battery pack or tool that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behaviour resulting in fire, explosion or
risk of injury.
■Do not expose a battery pack or tool to fire
or excessive temperature. Exposure to fire or
temperature above 130°C may cause explosion.
■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.
SERVICE
■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.
■Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
GENERAL 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
configuration 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.
■Wear eye protection. Further protective equipment
for hearing, head, hands, legs and feet is
recommended. Adequate protective equipment will
reduce personal injury by flying debris or accidental
contact with the saw chain.
■Do not operate a chainsaw in a tree, on a ladder,
from a rooftop, or any unstable support. Operation
of a chainsaw in this manner could result in serious
personal injury.
■Always keep proper footing and operate the
chainsaw only when standing on fixed, secure and
level surface. Slippery or unstable surfaces 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 fibres 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
fit the guide bar cover. 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 the bar and chain. Improperly tensioned
or lubricated chain may either break or increase the
chance for kickback.

4
■Cut wood only. Do not use chainsaw for purposes
not intended. For example: do not use chainsaw
for cutting metal, plastic, masonry or non-wood
building materials. Use of the chainsaw for operations
different than intended could result in a hazardous
situation.
■Do not attempt to fell a tree until you have an
understanding of the risks and how to avoid them.
Serious injury could occur to the operator or bystanders
while felling a tree.
■This chainsaw is not intended for tree felling. Use of
the chainsaw for operations different that intended could
result in serious injury to the operator or bystanders.
■Follow all instructions when clearing jammed
material, storing or servicing the chainsaw. Make
sure the switch is off and the battery pack is removed.
Unexpected actuation of the chainsaw while clearing
jammed material or servicing may result in serious
personal injury.
CAUSES AND OPERATOR PREVENTION OF
KICKBACK:
Kickback may occur when the nose or tip of the guide bar
touches an object, or when the wood closes in and pinches
the saw chain in the cut.
Tip contact in some cases may cause a sudden reverse
reaction, kicking the guide bar up and back towards the
operator.
Pinching the saw chain along the top of the guide bar may
push the guide bar rapidly back towards the operator.
Either of these reactions may cause you to lose control of
the saw which could result in serious personal injury. Do
not rely exclusively upon the safety devices built into your
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:
■Maintain a firm grip, with thumbs and fingers
encircling the chainsaw handles, with both hands
on the saw and position your body and arm to allow
you to resist kickback forces. Kickback forces can
be controlled by the operator, if proper precautions are
taken. Do not let go of the chainsaw.
■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.
■Only use replacement guide bars and saw chains
specified by the manufacturer. Incorrect replacement
guide bars and saw chains may cause chain breakage
and/or kickback.
■Follow the manufacturer’s sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to
increased kickback.
ADDITIONAL SAFETY WARNINGS
■Attend a professionally organised course on the use
and maintenance of chainsaws, preventative actions,
and first aid. Keep these instructions safe for later use.
■Chainsaws are potentially dangerous tools. Accidents
involving the use of chainsaws often result in loss of
limbs or death. Falling branches, toppling trees, rolling
logs can all kill. Diseased or rotting timber poses
additional hazards.Assess your capability of completing
the task safely. If there is any doubt, leave it to a
professional tree surgeon.
■Do not cut vines or small undergrowth (less than 75 mm
in diameter).
■It is recommended to practise cutting logs on a saw-
horse or cradle when operating the product for the first
time.
■The size of the work area depends on the job being
performed and the size of the tree or workpiece
involved. For example, felling a tree requires a larger
work area than making other cuts, such as bucking
cuts. The operator needs to be aware and in control of
everything happening in the work area.
■Do not cut with your body in line with the guide bar and
chain. If you experience kickback, this position helps
prevent the chain from coming into contact with your
head or body.
■Do not use a back-and-forward sawing motion. Let the
chain do the work. Keep the chain sharp, and do not try
to push the chain through the cut.
■Do not put pressure on the saw at the end of the cut.
Be ready to take on the weight of the saw as it cuts free
from the wood. Failure to do so could result in possible
serious personal injury.
■Do not stop the saw in the middle of a cutting operation.
Keep the saw running until it is already removed from
the cut.
■To reduce the risk of injury associated with contacting
moving parts, always turn off the motor, apply the chain
brake, remove the battery pack, and make sure that all
moving parts have come to a complete stop:
●before cleaning or clearing a blockage
●before leaving the product unattended
●before installing or removing attachments
●before checking, conducting maintenance, or
working on the product
■Injuries may be caused, or aggravated, by prolonged
use of the product. When using the product for
prolonged periods, ensure to take regular breaks.
■If the product is dropped, suffers heavy impact, or
begins to vibrate abnormally, immediately stop the
product and inspect for damage or identify the cause of
the vibration. Any damage should be properly repaired
or replaced by an authorised service centre.
■Operate the product only in temperatures between 0°C
and 40°C.
■Store the product in a location where the ambient
temperature is between -10°C and 50°C.

temperature is between 10°C and 38°C.
■Store the battery pack in a location where the ambient
temperature is between 0°C and 20°C.
INSTRUCTIONS CONCERNING THE PROPER
TECHNIQUES FOR BASIC FELLING, LIMBING,
AND CROSS-CUTTING
UNDERSTANDING THE FORCES WITHIN THE WOOD
When you understand the directional pressures and
stresses inside the wood, you can reduce the pinches or at
least expect them during your cutting. Tension in the wood
means the bres are being pulled apart, and if you cut in this
area, the kerf or cut tends to open as the saw goes through.
If a log is being supported on a saw-horse and the end is
hanging unsupported over the end, tension is created on
the upper surface due to the weight of the overhanging log
stretching the bres. Likewise, the underside of the log is
compressed and the bres are being pushed together. If a
cut is made in this area, the kerf tends to close up during
the cut. This cut would pinch the blade.
PUSH AND PULL
The reaction force is always opposite to the direction the
chain is moving. The operator must be ready to control the
tendency for the product to pull away and push backwards.
The product pulls away (forward motion) when cutting on
the bottom edge of the bar. The product pushes backwards
(towards the operator) when cutting along the top edge.
SAW JAMMED IN THE CUT
Turn o󰀨 the product, and remove the battery pack. Do not
try to force the chain and bar out of the cut as this is likely
to break the chain, which may swing back and strike the
operator. This situation normally occurs because the wood
is incorrectly supported, which forces the cut to close under
compression, thereby pinching the blade. If adjusting the
support does not release the bar and chain, use wooden
wedges or a lever to open the cut and release the saw.
Never try to start the chainsaw when the guide bar is
already in a cut or kerf.
SKATING/BOUNCING
When the chainsaw fails to dig in during a cut, the guide
bar can begin hopping or dangerously skidding along the
surface of the log or branch, possibly resulting in the loss
of control of the chainsaw. To prevent or reduce skating or
bouncing, always use the saw with both hands. Make sure
that the saw chain establishes a groove for cutting.
Never cut small, exible branches or brushes with your
chainsaw. Their size and exibility can easily cause the
saw to bounce towards you or bind up with enough force
to cause a kickback. The best tool for that kind of work is
a hand saw, an axe, pruning shears, or other hand tools.
FELLING A TREE
When bucking and felling operations are being performed
by two or more persons at the same time, the felling
operations 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 company should be notied immediately.
The chainsaw operator should keep on the uphill side of
the terrain as the tree is likely to roll or slide downhill after
it is felled.
An escape path should be planned and cleared as
necessary before cuts are started. The escape path should
extend back and diagonally to the rear of the expected line
of fall.
Before felling starts, consider the natural lean of the tree,
the location of larger branches, and the wind direction to
judge which way the tree will fall.
Remove dirt, stones, loose bark, nails, staples, and wire
from the tree.

6
Do not attempt to fell trees which are rotten or have been
damaged by wind, re, lightning, etc. This is extremely
dangerous and should only be completed by professional
tree surgeons.
1. Notching undercut
Make the notch 1/3 the diameter of the tree, perpendicular
to the direction of the fall. Make the lower horizontal
notching cut first. This will help to avoid pinching either the
saw chain or the guide bar when the second notch is being
made.
2. Felling-back cut
Make the felling-back cut at least 50 mm (2 in.) higher
than the horizontal notching cut. Keep the felling-back cut
parallel to the horizontal notching cut. Make the felling back
cut so enough wood is left to act as a hinge. The hinge
wood keeps the tree from twisting and falling in the wrong
direction. Do not cut through the hinge.
As the felling gets close to the hinge, the tree should begin
to fall. If there is any chance that the tree may not fall in
the desired direction or it may rock back and bind the saw
chain, stop cutting before the felling-back cut is complete
and use wedges of wood, plastic or aluminium to open the
cut and drop the tree along the desired line of fall.
When the tree begins to fall, remove the chainsaw from the
cut, stop the motor, put the chainsaw down, and use the
retreat path planned. Be alert for falling overhead limbs and
watch your footing.

REMOVING BUTTRESS ROOTS
A buttress root is a large root extending from the trunk of
the tree above the ground. Remove large buttress roots
before 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 after removing the large buttress roots.
BUCKING A LOG
Bucking is cutting a log into lengths. It is important to
make sure your footing is rm and your weight is evenly
distributed on both feet. When possible, the log should be
raised and supported by the use of limbs, logs or chocks.
Follow the simple directions for easy cutting. When the log
is supported along its entire length, it is cut from the top
(overbuck).
When the log is supported on one end, cut 1/3 the diameter
from the underside (underbuck). Then make the nished
cut by overbucking to meet the rst cut.

When bucking on a slope always stand on the uphill side of
the log. To maintain control when “cutting through”, release
the cutting pressure near the end of the cut without relaxing
your grip on the chainsaw handles. Don’t let the chain
contact the ground. After completing the cut, wait for the
saw chain to stop before you move the chainsaw. Always
stop the motor before moving from tree to tree.
LIMBING A TREE
Limbing is removing the branches from a fallen tree. When
limbing, leave larger lower limbs to support the log o󰀨 the
ground. Remove the small limbs in one cut. Branches
under tension should be cut from the bottom up to avoid
binding the chainsaw.
SPRINGPOLES
A springpole is any log, branch, rooted stump, or sapling
that is bent under tension by other wood so that it springs
back if the wood holding it is cut or removed.
On a fallen tree, a rooted stump has a high potential of

7
springing back to the upright position during the bucking
cut to separate the log from the stump. Watch out for
springpoles—they are dangerous. Do not attempt to cut
bent branches or stumps that are under tension unless you
are professionally trained and competent to do so.
WARNING! Springpoles are dangerous and could
strike the operator, causing the operator to lose control of
the chainsaw. This could result in a severe or fatal injury
to the operator. Cutting spring poles should be done by
trained users.

SAFETY DEVICES
Chain brake
Chain brakes are designed to quickly stop the chain from
rotating. When the chain brake lever/hand guard is pushed
towards the bar, the chain should stop immediately. A
chain brake does not prevent kickback. It only lowers the
risk of injury should the chain bar contact the operator’s
body during a kickback event. The chain brake should be
tested before each use for correct operation in both the run
and brake positions.
WARNING! If the chain brake does not stop the chain
immediately, or if the chain brake does not stay in the

8
run position without assistance, take the product to an
authorised service centre for repair before use.
Chain catcher
The chain catcher prevents the saw chain from being
thrown back towards the operator if the saw chain comes
loose or breaks.
Guide bars
Generally, guide bars with small radius tips have a
somewhat lower potential for kickback. Use a guide bar
and matching chain that is just long enough for the job.
Longer bars increase the risk of loss of control during
sawing. Regularly check the chain tension. When cutting
smaller branches (less than the full length of the guide bar)
the chain is more likely to be thrown o󰀨 if the tension is
not correct.
Low-kickback saw chain
The low-kickback saw chain helps to reduce the possibility
of a kickback event.
The rakers (depth gauges) ahead of each cutter can
minimise the force of a kickback reaction by preventing the
cutters from digging in too deeply. Use only replacement
guide bar and chain combinations that are recommended
by the manufacturer.
As saw chains are sharpened, they lose some of the low-
kickback qualities, and extra caution is required. For your
safety, replace saw chains when cutting performance
decreases.
Spiked bumper
The integral bumper spike may be used as a pivot when
making a cut. It helps to keep the body of the chainsaw
steady while cutting. When cutting, push the product
forward until the spikes dig into the edge of the wood, then
move the rear handle up or down in the direction of the
cutting line to help ease the physical strain of cutting.
OVER-TEMPERATURE PROTECTION
The battery pack has over-temperature protection, which
is designed to protect the battery cells from damage in the
event of high temperatures. This feature may cause the
battery to stop powering the product until the battery cells
cool down. If the battery pack is warm to touch, allow it to
cool down before resuming operation. If the product still
does not work, connect the battery pack to the charger,
which can also indicate over-temperature protection. When
the battery cells cool down, the charger begins to charge
the battery.
NOTE: High ambient temperatures above 30° C and high-
power tools, such as chainsaws, can cause the battery
cells to heat up faster. Monitor the battery pack regularly,
and if it is warm to touch, change the battery or allow the
battery to cool down.
NOTE: The battery pack LED indicator stops working if the
battery protection feature has caused the battery pack to
stop powering the product.
