GENERAL POWER TOOL 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) 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 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

2
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 the switch is dangerous and must be repaired.
■Disconnect the plug from the power source and/
or remove the battery pack, if detachable, 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 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. lf damaged, have the power
tool repaired before use. Many accidents are caused
by poorly maíntained 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 authorised service providers.
ADDITIONAL GENERAL SAFETY WARNINGS
■Some regions have regulations that restrict the use of
the product. Check with your local authority for advice.
■Never allow children or people who are unfamiliar with
the instructions to use the product. Local regulations
may restrict the age of the operator.
■Ensure before each use that all controls and safety
devices function correctly. Do not use the product if the
“off” switch does not stop the motor.
■Wear full eye and hearing protection, strong sturdy
boots and gloves, and head protection while operating
the product. Use a face mask if operation is dusty.
■Use of hearing protection reduces the ability to hear
warnings (shouts or alarms). The operator must pay
extra attention to what is going on in the work area.
■Keep firm footing and balance. Do not overreach.
Overreaching can result in loss of balance and can
increase the risk of kickback.
■Do not wear loose-fitting clothing, short trousers, or
jewellery of any kind.
■Secure long hair so it is above shoulder level to prevent
entanglement in moving parts.
■Beware of thrown, flying, or falling objects. Keep all
bystanders, children, and animals at least 15 m away
from the work area.

3
■Do not operate the product in poor lighting. The
operator requires a clear view of the work area to
identify potential hazards.
■Operating similar tools nearby increases both the risk
of hearing injury and the potential for other persons to
enter your work area.
■Keep all parts of your body away from any moving part.
■Inspect the product before each use. Check for correct
operation of all controls, including the chain brake.
Check for loose fasteners, and make sure that all
guards and handles are properly and securely attached.
Replace any damaged parts before use.
■Do 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.
ADDITIONAL BATTERY SAFETY WARNINGS
WARNING
To reduce the risk of fire, personal injury, and product
damage due to short circuit, never immerse your tool,
battery pack, or charger in fluid or allow a fluid to flow
inside them. Corrosive or conductive fluids, such as
seawater, certain industrial chemicals, and bleach or
bleach-containing products, etc., can cause a short
circuit.
OVER-TEMPERATURE PROTECTION
The battery pack has an 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. Feel the battery pack; if it 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 chainsaw, 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.
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 or its own cord. 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.
■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.
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.

4
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.
■Use only replacement bars and chains that are
specified by the manufacturer. Incorrect replacement
bars and 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 CHAINSAW SAFETY WARNINGS
■Cut logs on a saw-horse or cradle when operating the
product for the first time.
■Ensure that all guards, handles, and spiked bumper are
properly fitted and are in good condition.
■Persons using the product should be in good health.
The product is heavy, 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 product.
■Do not start using the product until you have a clear
work area, secure footing, and a planned retreat path
away from a falling tree.
■Beware of the emission of lubricant mist and saw dust.
Wear a mask or respirator, if required.
■Do not cut vines and small undergrowth (less than 75
mm in diameter).
■Always hold the chainsaw with both hands when
operating the saw. Use a firm grip with thumbs and
fingers encircling the chainsaw handles. Right hand
must be on the rear handle and left hand on the front
handle.
■Before starting the product, make sure that the saw
chain is not contacting any object.
■Do not modify the product in any way or use it to power
any attachments or devices that are not recommended
by the manufacturer for the product.
■There should be a first-aid kit containing large
wound dressings and a means to summon attention
(e.g., whistle) close to the operator. A larger more
comprehensive kit should be reasonably nearby.
■Wear a helmet at all times when operating the product.
A helmet, equipped with mesh visor, can help reduce
the risk of injury to the face and the head if kickback
occurs.
■An 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.
■You 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.
■To reduce the risk of injury associated with contacting
moving parts, always stop the product, apply the chain
brake, remove the battery pack, and make sure that all
moving parts have come to a stop before:
–cleaning or clearing a blockage
–leaving the product unattended
–installing or removing attachments
–checking, performing maintenance, or working on
the product
■The 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.
■Do not cut with your body in line with the guide bar and
chain. If you do experience kickback, this 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 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
control the tendency for the machine to pull away (forward
motion) when cutting on the bottom edge of the bar and the
push backwards (towards the operator) when cutting along
the top edge.
Saw jammed in the cut
Stop the chainsaw, and engage the chain brake. 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 helps to reduce the risk of injury to the
operator. Wear the following items when operating a
chainsaw:
●Safety helmet
●Hearing protection
●Eye and face protection
●Gloves
●Leg protection (chaps)
●Chainsaw safety boots
●Chainsaw jackets for upper body protection
INSTRUCTIONS CONCERNING THE PROPER TECH-
NIQUES 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 bers 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 then
tension is created on the upper surface due to the weight
of the overhanging log stretching the bers. Likewise, the
underside of the log is compressed and the bers 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
utility line, the company should be notied immediately.
Stand on the uphill side of the terrain as the tree is likely to
roll or slide downhill after it is felled.
Plan and clear an escape path before cuts are starting
cuts. The escape path should extend back and diagonally
to the rear of the expected line of fall.
Before starting to fell a tree, 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 that 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
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 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
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 after you have removed the large buttress roots.
Bucking a log
See page 19.
Bucking is the process of cutting a log into lengths. Make
sure that 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 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). Make the nished cut by
overbucking to meet the rst cut.
When the log is supported on both ends, cut 1/3 the
diameter from the top (overbuck). Make the nished cut by
underbucking the lower 2/3 to meet the rst cut.
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. Do
not 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 the process of 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

6
one cut. Branches under tension should be cut from the
bottom up to avoid binding the chainsaw.
Cutting spring poles
See page 20.
A spring pole 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
springing back to the upright position during the bucking
cut to separate the log from the stump. Watch out for spring
poles—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
Spring poles 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:
■injury caused by vibration
–Always use the right tool for the job, use designated
handles, and restrict working time and exposure.
■damage to hearing due to exposure to noise
–Wear hearing protection and limit exposure.
■injury caused by contact with exposed saw teeth of the
chain (cutting hazards)
■injury caused by parts ejected from the saw chain
(cutting/injection hazards)
■injury caused by thrown-out pieces of the workpiece
(wood chips, splinters)
■injury caused by dust and particles
■injury to the skin caused by contact with lubricants
RISK REDUCTION
It has been reported that vibrations from hand-held tools
may contribute to a condition called Raynaud’s Syndrome
in certain individuals. Symptoms may include tingling,
numbness, and blanching of the ngers, usually apparent
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:
■Keep 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.
■After each period of operation, exercise to increase
blood circulation.
■Take frequent work breaks. Limit the amount of
exposure per day.
■Protective gloves available from professional chainsaw
retailers are designed specifically for chainsaw use ,
which give protection, good grip, and reduce the effect
of handle vibration.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your physician.
WARNING
Injuries may be caused, or aggravated, by prolonged
use of a tool. When using any tool for prolonged periods,
ensure you take regular breaks.
SAFETY DEVICES
Low kickback saw chain
A low-kick-back saw chain helps to reduce the possibility
of a kickback event.
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. 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 machine
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. This method helps ease the physical strain of
cutting.
Guide bars
Generally, guide bars with small radius tips have 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 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.
OPERATION
WARNING
If any parts are damaged or missing do not operate this
product until the parts are replaced. Failure to heed this
warning could result in serious personal injury.

ADJUSTING THE CHAIN TENSION
See page 23.
1. Loosen the chain tensioner knob slightly by turning it
counterclockwise.
2. Check the chain tension frequently while adjusting. To
increase the chain tension, turn the chain tensioner
adjustment ring clockwise. To reduce the chain
tension, turn the chain tensioner adjustment ring
counterclockwise.
3. The chain tension is correct when the gap between the
cutter in the chain and the bar is between 3 mm - 4
mm. Pull the chain in the middle of the lower side of the
bar downwards (away from the bar) and measure the
distance between the bar and the chain cutters.
4. Tighten the chain tensioner knob by turning it clockwise.
ADDING CHAIN LUBRICATING OIL
See page 13.
WARNING
Never work without chain lubricant. If the saw chain is
running without lubricant, guide bar and saw chain can
be damaged. It is therefore essential to check the oil
level in the oil level gauge frequently and every time
before starting to use the chain saw.
1. Clear surface around the oil cap to prevent
contamination.
2. Remove the cap from the oil tank.
3. Pour the oil into the oil tank and monitor the oil level
gauge. Ensure that no dirt enters the oil tank while
filling.
4. Close the oil tank and tighten the cap. Wipe away any
spillage.
5. One full oil tank enables you to use the saw for 9-30
min.
Recommended chain lubricating oil
■The manufacturer recommends to use only RYOBI
chainsaw lubricating oil. (Available from Bunnings
stores)
INSTALLING BATTERY PACK
See page 13.
1. Place the battery pack in the chain saw. Align raised
ribs on battery pack with grooves in the chain saw’s
battery port.
2. Make sure that the latch on bottom of the battery
pack snaps in place and that battery pack is securely
attached in the chain saw before beginning operation.

Loosen the chain tensioner knob slightly by turning it
counterclockwise. Check the chain tension frequently while
adjusting. To increase the chain tension, turn the chain tensioner
adjustment ring clockwise. To reduce the chain tension, turn the

from the trunk of the tree above the
ground. Remove large buttress roots
prior to felling. Make the horizontal cut
into the buttress first, followed by the
vertical cut.
2. Remove the resulting loose section
from the work area. Follow the correct
tree felling procedure after you have
removed the large buttress roots.
WARNING: When removing the roots, make
sure not to cut into the soil to avoid damage
to the bar and chain.
