WORK AREA SAFETY
ŶKeep work area clean and well lit. Cluttered or dark
areas invite accidents.
ŶDo not operate power tools in explosive
atmospheres, such as in the presence of flammable
liquids, gases or dust. 3RZHU WRROV FUHDWH VSDUNV
which may ignite the dust or fumes.
ŶKeep children and bystanders away while operating
a power tool. Distractions can cause you to lose
control.
ELECTRICAL SAFETY
ŶPower 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.
ŶAvoid 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.
ŶDo not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
ŶDo 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.
ŶWhen 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.
ŶIf 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
ŶStay 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

POWER TOOL USE AND CARE
ŶDo 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.
ŶDo not use the power tool if the switch does not turn
it on and off. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
ŶDisconnect the plug from the power source and/or
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.
ŶStore 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.
3RZHU WRROV DUH GDQJHURXV LQ WKH KDQGV RI XQWUDLQHG
users.
ŶMaintain power tools. 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.
ŶKeep cutting tools sharp and clean. 3URSHUO\
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
ŶUse 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.
BATTERY TOOL USE AND CARE
ŶRecharge 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.
ŶUse power tools only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire
ŶWhen 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.
ŶUnder 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.
SERVICE
ŶHave 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.

dusty.
ŶUse of hearing protection reduces the ability to hear
ZDUQLQJV VKRXWV RU DODUPV 7KH RSHUDWRU PXVW SD\
extra attention to what is going on in the work area.
ŶKeep firm footing and balance. Do not overreach.
Overreaching can result in loss of balance and can
increase the risk of kickback.
ŶDo not wear loose fitting clothing, short trousers, or
jewellery of any kind.
ŶSecure long hair so it is above shoulder level to prevent
entanglement in moving parts.
ŶBeware of thrown, flying, or falling objects. Keep all
bystanders, children, and animals at least 15 m away
from the work area.
ŶDo not operate in poor lighting. The operator requires a
clear view of the work area to identify potential hazards.
ŶOperating similar tools nearby increases both the risk
of hearing injury and the potential for other persons to
enter your work area.
ŶKeep all parts of your body away from any moving part.
ŶInspect the product before each use. Check for correct
operation of all controls, including the chain brake.
Check for loose fasteners, make sure all guards and
handles are properly and securely attached. Replace
any damaged parts before use.
ŶDo not modify the product in any way or use parts
and accessories which are not recommended by the
manufacturer.
WARNING
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.
CHAINSAW SAFETY WARNINGS
ŶKeep all parts of the body away from the saw chain
when the chainsaw is operating. Before you start

3
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.
ŶAlways 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.
ŶHold the power tool by insulated gripping surface
only, because the saw chain may contact hidden
wiring. Saw chains contacting a “live” wire may make
exposed metal parts of the power tool “live” and could
give the operator an electric shock.
ŶWear safety glasses and hearing protection. Further
protective equipment for head, hands, legs and feet
is recommended. Adequate protective clothing will
reduce personal injury by flying debris or accidental
contact with the saw chain.
ŶDo not operate a chainsaw in a tree. Operation of
a chainsaw while up in a tree may result in personal
injury.
ŶAlways keep proper footing and operate the
chainsaw only when standing on fixed, secure and
level surface. Slippery or unstable surfaces such as
ladders may cause a loss of balance or control of the
chainsaw.
ŶWhen 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.
ŶUse 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.
ŶCarry 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. 3URSHU KDQGOLQJ RI WKH
chainsaw will reduce the likelihood of accidental contact
with the moving saw chain.
ŶFollow instructions for lubricating, chain tensioning
and changing accessories. Improperly tensioned
or lubricated chain may either break or increase the
chance for kickback.
ŶKeep handles dry, clean, and free from oil and
grease. Greasy, oily handles are slippery causing loss
of control.
ŶCut 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.
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.
3LQFKLQJWKHVDZFKDLQDORQJWKHWRSRIWKHJXLGHEDUPD\
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:
ŶMaintain 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.
ŶDo 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.
ŶOnly use replacement bars and chains specified
by the manufacturer. Incorrect replacement bars and
chains may cause chain breakage and/or kickback.
ŶFollow the manufacturer’s sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to
increased kickback.

The chainsaw is a heavy unit so the operator requires
to be physically fit. The operator should be alert, have
good vision, mobility, balance and manual dexterity. If
there is any doubt, do not operate the chainsaw.
ŶDo not start using the product until you have a clear
work area, secure footing, and a planned retreat path
away from the falling tree.
ŶBeware of the emission of lubricant mist and saw dust.
Wear a mask or respirator if required.

comprehensive kit should be reasonably nearby.
ŶThe operator may be tempted to remove the helmet if
there is no danger of falling objects in the work area, but
remember the helmet, particularly with the mesh visor,
can help reduce the potential for injury to the face and
head if kickback occurs.
ŶAn incorrectly tensioned chain can jump off the guide
bar and could result in serious injury or fatality. The
length of chain depends on the temperature. Check the
tension frequently.
ŶYou should get used to your new chainsaw by making
simple cuts on securely supported wood. Do this
whenever you have not operated the saw for some
time.
ŶTo reduce the risk of injury associated with contacting
moving parts, always stop the motor, apply chain brake,
remove the battery pack and make sure all moving
parts have come to a stop before:
–cleaning or clearing a blockage
–leaving the product unattended
–installing or removing attachments
–checking, maintenance or working on the machine
ŶThe size of the work area depends on the job being
performed as well as the size of the tree or work piece
involved. For example, felling a tree requires a larger
work area than making other cuts, i.e., bucking cuts,
etc. The operator needs to be aware and in control of
everything happening in this work area.
ŶDo not cut with your body in line with the guide bar
and chain. If you do experience kickback this will help
prevent the chain coming into contact with your head
or body.
ŶDo not use a back and forward sawing motion, let the
chain do the work, keep the chain sharp and don’t try to
push the chain through the cut.
ŶDo 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.
ŶDo not stop the saw in the middle of a cutting operation.
Keep the saw running until it is already removed from
the cut.
Push and pull
The reaction force is always opposite to the direction the
chain is moving. Thus, the operator must be ready to

the top edge.
Saw jammed in the cut
Stop the chainsaw and make it safe. 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 and forcing 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.
Personal protective equipment
Good quality, personal protective equipment as used
by professionals will help to reduce the risk of injury to
the operator. The following items should be used when
operating your chainsaw:
ŶSafety helmet
ŶHearing protection
ŶEye, ear, and face protection
ŶGloves

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

cut in this area the “kerf” or cut will tend 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 then
tension is created on the upper surface due to the weight

are being pushed together. If a cut is made in this area the
kerf will have the tendency to close up during the cut. This
would pinch the blade.
Felling a tree
See page 17 - 18.
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
XWLOLW\OLQHWKHFRPSDQ\VKRXOGEHQRWL¿HGLPPHGLDWHO\
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 is started, 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.
Do not attempt to fell trees which are rotten or have been

1. Notching undercut
See page 17 - 18.
Make the notch 1/3 the diameter of the tree,
perpendicular to the direction of falls. 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
See page 17 - 18.
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 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, then
use the retreat path planned. Be alert for overhead
limbs falling and watch your footing.
Removing buttress roots
See page 18.
A buttress root is a large root extending from the trunk of
the tree above the ground. Remove large buttress roots
SULRUWRIHOOLQJ0DNHWKHKRUL]RQWDOFXWLQWRWKHEXWWUHVV¿UVW
followed by the vertical cut. Remove the resulting loose
section from the work area. Follow the correct tree felling
procedure after you have removed the large buttress roots.
Bucking a log
See page 19.
Bucking is cutting a log into lengths. It is important to
PDNH VXUH \RXU IRRWLQJ LV ¿UP DQG \RXU ZHLJKW LV HYHQO\
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

FXWE\XQGHUEXFNLQJWKHORZHUWRPHHWWKH¿UVWFXW
When bucking on a slope always stand on the uphill side
of the log. When “cutting through”, to maintain complete
control 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
See page 20.
Limbing is removing the branches from a fallen tree. When
limbing leave larger lower limbs to support the log off 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
See page 20.
A springpole is any log, branch, rooted stump, or sapling
which 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
springing back to the upright position during the bucking
cut to separate the log from the stump. Watch out for
springpoles—they are dangerous.
WARNING
Springpoles are dangerous and could strike the operator,
causing the operator to lose control of the chainsaw.
This could result in severe or fatal injury to the operator.
This should be done by trained users.
RESIDUAL RISKS
Even when the product is used as prescribed, it is still
impossible to completely eliminate certain residual risk
factors. The following hazards may arise in use and the
operator should pay special attention to avoid the following:
ŶInjury caused by vibration
ƔAlways use the right tool for the job, use designated
handles and restrict working time and exposure.
ŶDamage to hearing due to exposure to noise
ƔWear hearing protection and limit exposure.

upon exposure to cold. Hereditary factors, exposure to
cold and dampness, diet, smoking and work practices
are all thought to contribute to the development of these
symptoms. There are measures that can be taken by the
operator to possibly reduce the effects of vibration:
ŶKeep your body warm in cold weather. When operating
the unit wear gloves to keep the hands and wrists
warm. It is reported that cold weather is a major factor
contributing to Raynaud’s Syndrome.
ŶAfter each period of operation, exercise to increase
blood circulation.

7KH UDNHUV GHSWK JDXJHV DKHDG RI HDFK FXWWHU FDQ
minimize the force of a kickback reaction by preventing the
cutters from digging in too deeply. Only use replacement
guide bar and chain combinations 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 machine
forward until the spikes dig into the edge of the wood, then
by moving the rear handle up or down in the direction of the
cutting line it can help ease the physical strain of cutting
Guide bars
Generally, guide bars with small radius tips have somewhat
lower potential for kickback. You should use a guide bar
and matching chain which 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
VPDOOHUEUDQFKHVOHVVWKDQWKHIXOOOHQJWKRIWKHJXLGHEDU
the chain is more likely to be thrown off if the tension is
not correct.
Chain brake
Chain brakes are designed to quickly stop the chain
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.
Chain catcher
A chain catcher prevents the saw chain from being thrown
back towards the operator if the saw chain comes loose
