GENERAL POWER TOOL SAFETY WARNINGS
WARNING
Read all safety warnings and all instructions. Failure
to follow the warnings and instructions 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 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, clothing and gloves 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
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 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.

2
■Maintain 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.
■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 surtaces do not allow for safe handlíng 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
ereate 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. lf contact
accidentally occurs, flush with water. lf liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause írritation 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.
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 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
gloves, as well as head protection while operating the
product; use a face mask if operation is dusty.
■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 work area.
■Do not operate in poor lighting. The operator requires a
clear view of the work area to identify potential hazards.
■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 working area.
■Operating similar tools nearby increases both the risk
of hearing injury and the potential for other persons to
enter your working area.
■Keep firm footing and balance. Do not overreach.
Overreaching can result in loss of balance and can
increase the risk of kickback.
■Keep all parts of your body away from any moving part.
■Inspect the product before each use. Check for correct
operation of all controls. Check for loose fasteners,
make sure 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.
■Do not allow familiarity with the product to make you
careless. A careless fraction of a second is sufficient to
inflict serious injury.
■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.
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.
PRUNER SAFETY WARNINGS
■Do not use the product when there is a possibility of
thunderstorm or lightning. Store the product safely
indoors.

3
■Ensure all guards, handles are properly fitted, and are
in good condition.
■Do not start using the product until you have a clear
work area, secure footing, and a planned retreat path
away from the falling branches or limbs.
■Beware of the emission of lubricant mist and saw dust.
Wear mask or respirator if required.
■During operation, hold the product with both hands.
Use one hand to firmly grasp the front hand grip. Use
the other hand to grasp the rear handle and operate the
trigger release and on/off trigger.
■Hold the product 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 power tool “live” and could give the
operator an electric shock.
■Do not modify the product in any way or use it to power
any attachments or devices not recommended by the
manufacturer.
■Your product comes with a harness. You must use it
while operating the product. It will assist you to control
the drop of the product after the cut is completed. It will
also help support the weight of the product during use
and while moving between pruning positions.
■Identify the quick release mechanism and practice
using it before you start using the product. Its correct
use may prevent serious injury in the case of an
emergency. Never wear additional clothing over
the harness or otherwise restrict access to the quick
release mechanism.
■Before starting the product, make sure the saw chain is
not contacting any object.
■An incorrectly tensioned chain can jump off the guide
bar and could result in serious injury. Check before
each use and frequently, especially a new chain.
■To reduce the risk of injury associated with contacting
moving parts, always stop the product, remove the
battery pack, and make sure all moving parts have
come to a complete stop:
●before servicing
●before leaving the product unattended
●before clearing a blockage
●before checking, cleaning, and working on the
product
●before changing accessories
●after striking a foreign object
●whenever performing maintenance
●whenever the product starts to vibrate abnormally
■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
product, which could result in serious personal injury.
Do not rely exclusively upon the safety devices built into
the product. As a product 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 the following precautions:
●Make sure that the area in which you are cutting
is free from obstructions. Do not let the nose of
the guide bar contact a branch, limb, or any other
obstruction while you are operating the product.
●Maintain a firm grip, with both hands on the product
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 product.
●Do not overreach. This helps prevent unintended tip
contact and enables better control of the product in
unexpected situations.
●Only use replacement bars and chains specified by
the manufacturer. Incorrect replacement bars and
chains may cause chain breakage and/or kickback.
●Sharpening the chain safely is a skilled task.
Therefore, the manufacturer strongly recommends
that a worn or dull chain is replaced with a new
one. The part number is available in the product
specification table in this manual.
■Do not use on a ladder or unstable support. Always cut
with both feet on solid ground to prevent being pulled
off balance.
■To protect yourself from electrocution, do not operate
within 10 m of overhead electrical lines.
■Beware of falling branches or those which rebound
after hitting the ground.
■Use extreme caution when cutting small-sized brush
and saplings because slender material may catch the
saw chain and be whipped toward you or pull you off
balance.
■When cutting a limb that is under tension, be alert for
spring back so that you will not be struck when tension
in wood fibres are released.
■If the cutting performance deteriorates over time, check
if the chain teeth are sharp and clean. If necessary,
replace the original chain (and bar) as recommended
by the manufacturer.
■If the chain and bar become pinched or trapped
in branches too high to reach, seek advice from a
professional tree service specialist about safe removal
of the cutting means.
WARNING
Check that all the shaft couplings on the extension pole
and tool are securely fastened before each use and at
frequent intervals.

RISK REDUCTION
It has been reported that vibrations from handheld tools
may contribute to a condition called Raynaud’s Syndrome.
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 product, 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.
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.

Note
Warning
OPERATION
■Study the condition of the tree and branches before
starting work. If there are signs of damage, rot or decay,
do not attempt to prune yourself. Damaged or rotten
branches are highly unstable. Seek the services of a
professional tree surgeon.
■Never stand under the branch to be pruned.
■Pruned branches do not always fall cleanly to the
ground. They are easily caught and deflected by
other foliage. Ensure that a safety zone at least twice
the length of the branch to be cut is available and
maintained during your pruning. If this is not possible,
seek the services of a professional tree surgeon.
■Ensure that the falling branch is not a danger to
yourself, bystanders or property, including utility cables.
■Never operate the product with the pole at an angle of
greater than 60° from the horizontal.
■Never operate the product with the cutting means
closer than 10 m from overhead power lines.
■Do not force the product, let the chain do the work at
its own speed.
■Do not try to cut the branch too close to the tree trunk.
Leave about 15 cm from the trunk to the cut.
■Rest the saw bar on the branch to be pruned and push
the saw gently forwards so that the ribbed bumper also
contacts the branch. This will aid stability, cutting, and
provide cleaner cuts.
■Small and thin branches that are not heavy can be cut with
one cut using the bottom of the saw bar.
■Branches with larger diameter and are heavier may
break or split during the cut so the user must make a
first cut from under the branch using the top of the saw
bar. The first cut should be approximately one-third of
the way through the branch.
■Consider pruning large branches in manageable
sections rather than as a whole.
■Never try to restart a previous cut with the chain and
bar in the earlier cut. Always start a new cut. This will
reduce the risk of kickback and potential injury.
