GENERAL 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
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.

2
■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.
■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 surfaces do not allow for safe handling and
control of the tool in unexpected situations.
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 SAFETY WARNINGS
■Some regions have regulations that restrict the use of
the product to some operation. 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/engine.
■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.
■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.
■Beware of thrown, flying or falling objects; keep all
bystanders, children, and pets at least 15 m away from
work area. Stop the product if anyone enters the area.
■Do not operate in poor lighting. The operator requires a
clear view of the work area to identify potential hazards.
■Keep firm footing and balance. Do not overreach.
Overreaching can result in loss of balance and can
increase the risk of kickback.
■Do not use the product when tired, ill, or under the
influence of alcohol, drugs, or under medication.
■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 let familiarity of the product allow you to become
complacent and ignore tool safety principles. A careless
action can cause severe injury within a fraction of a
second.
■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
■Never use the pruner when there is a possibility of
thunderstorm or lightning. Store the pruner and/or the
power cables safely indoors.
■Ensure all guards and 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.
■Always hold the pruner with both hands when operating

3
it. Use one hand to firmly grasp the front hand grip. Use
the other hand to grasp the rear handle and operate
the product.
■Hold the product through the 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 product “live” and could give the
operator an electric shock.
■Do not modify your product in any way or use it to
power any attachments or devices not recommended
by the manufacturer for your pruner.
■The pruner comes with a harness. You must use it
while operating the pruner. It will assist you to control
the drop of the pruner 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 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 checking, cleaning, and working on the
product
●before changing accessories,
●before leaving the product unattended
●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 closed in and
pinches the saw chain in 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 your product. As a pruner 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:
●With a basic understanding of kickback, you can
reduce or eliminate the element of surprise. Sudden
surprise contributes to accidents.
●Make sure that the area in which you are cutting
is free from obstructions. Do not let the nose of
the guide bar contact 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 pruner.
●Do not overreach. This helps prevent unintended tip
contact and enables better control of the pruner 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, available from your authorised RYOBI service
centre. 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.
■Remove branches in sections. Do not operate in
dangerous positions. 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 fibers are released.
■If the cutting performance deteriorates over time,
check if the chain teeth are sharp and clean. Replace
with original chain (and bar) as recommended by the
manufacturer if necessary.
■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 product are securely fastened before each use and
at frequent intervals.
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 product:
■Safety helmet
■Hearing protection
■Eye and face protection
■Gloves
■Footwear

4
OPERATION
■Study the condition of the tree and branches before
starting work. If there are signs of damage, rot or
decay, do not operate the product. 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 when 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° horizontally.
■Never operate the pruner 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 branches, which are both thin in diameter and
not heavy, can be cut with one cut using the bottom of
the saw bar.
■For larger diameter and heavier branches, where the
branch may break or split during the cut should be cut
first from under the branch using the top of the saw
bar. Make this cut approximately one third of the way
through the branch. Then make a second cut from
above the branch using the bottom of the saw bar to
join the first cut.
■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.
TRANSPORTATION AND STORAGE
■Stop the product, and remove the battery pack. Allow
the product to cool down before storing or transporting
in a vehicle.
■Clean all foreign material from the product. Store it in a
cool, dry, and well-ventilated place that is inaccessible
to children. Keep away from corrosive agents such
as garden chemicals and de-icing salts. Do not store
outdoors.
■When storing the product for a long period of time (one
month or longer), be sure the chain is lightly lubricated
to prevent rust. The manufacturer recommends the use
of RYOBI bar and chain lubricant, which is available
from your RYOBI authorised service centre.
■Cover the saw bar with the scabbard.
■For transportation, secure the product against
movement or falling to prevent injury to persons or
damage to the product.

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 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.
