WARNING
When using the product, the safety rules must be
followed. For your own safety and that of bystanders, you
must read and fully understand these instructions before
operating the product. Please keep these instructions
safe for later use.
GENERAL SAFETY WARNINGS
WARNING
Read all safety warnings and all instructions. Failure
to follow the warnings and instructions may result in
HOHFWULFVKRFN¿UHDQGRUVHULRXVLQMXU\
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
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. Power tools create sparks
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
of inattention while operating power tools may result in
VHULRXVSHUVRQDOLQMXU\
ŶUse 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
SHUVRQDOLQMXULHV
ŶPrevent 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.
ŶRemove 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
LQMXU\
ŶDo not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
ŶDress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves away
from moving parts. /RRVH FORWKHV MHZHOOHU\ RU ORQJ
hair can be caught in moving parts.
ŶIf 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.
POWER TOOL USE AND CARE
ŶDo not force the power tool. Use the correct power
tool for your application. The correct power tool will
GRWKHMREEHWWHUDQGVDIHUDWWKHUDWHIRUZKLFKLWZDV
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.
Power tools are dangerous in the hands of untrained
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. Properly
maintained cutting tools with sharp cutting edges are

2
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.
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.
ADDITIONAL GENERAL SAFETY WARNINGS
ŶSome regions have regulations that restrict the use of
the product. Check with your local authority for advice.
ŶNever allow children or people unfamiliar with the
instructions to use the product. Local regulations may
restrict the age of the operator.
ŶEnsure 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.
ŶWear 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.
ŶDo not wear loose fitting clothing, short trousers or
MHZHOOHU\RIDQ\NLQG

bystanders, children, and animals at least 15 m away
from work area.
ŶDo not operate in poor lighting. The operator requires a
clear view of the work area to identify potential hazards.
ŶUse 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.
ŶOperating similar tools nearby increases both the risk

ŶKeep firm footing and balance. Do not overreach.
Overreaching can result in loss of balance and can
increase the risk of kickback.
ŶKeep all parts of your body away from any moving part.
ŶInspect the machine 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.
ŶDo not modify the machine in any way or use parts
and accessories which are not recommended by the
manufacturer.
ŶDo not let familiarity gained from frequent use of
machines allow you to become complacent and ignore
tool safety principles. A careless action can cause
VHYHUHLQMXU\ZLWKLQDIUDFWLRQRIDVHFRQG
ŶKeep 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.
ŶOnly use a weather proof extension cord. Check the
extension cord before every use for damage. Always
uncoil the extension cord during use because coiled
cords can overheat. Damaged extension cords should
not be repaired, they should be replaced with an
equivalent type.
WARNING
If the machine is dropped, suffers heavy impact or begins
to vibrate abnormally, immediately stop the machine 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
ŶNever use the pruner when there is a possibility of
thunderstorm or lightning. Store the pruner and the
power cables safely indoors.
ŶEnsure all guards, handles are properly fitted and are
in good condition.
ŶDo 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.
ŶBeware of the emission of lubricant mist and saw dust.
Wear mask or respirator if required.
ŶElectrical power should be supplied via a residual
current device (RCD) with a tripping current of not more
than 30 mA.
ŶIf the power cable becomes damaged, you must return
the machine to an authorised service centre for repair
or replacement.
ŶAlways hold the pruner with both hands when operating
it. Use one hand to firmly grasp the front hand grip. Use
the other hand to grasp the rear handle and operate the
WULJJHUUHOHDVHDQGRQRIIWULJJHU
ŶHold the power tool 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.
ŶDo not modify your tool in any way or use it to power
any attachments or devices not recommended by the
manufacturer for your pruner.
ŶYour pruner comes with a harness. You must use it
whilst 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 machine during use
and whilst moving between pruning positions.
ŶIdentify the quick release mechanism and practice
using it before you start using the machine. Its

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 machine which could result in serious personal

DQGRULQFRUUHFWRSHUDWLQJSURFHGXUHVRUFRQGLWLRQVDQG
can be avoided by taking proper precautions as given
below:
ƔWith a basic understanding of kickback, you can
reduce or eliminate the element of surprise. Sudden
surprise contributes to accidents.
ƔMake 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 unit.
ƔMaintain a firm grip, with both hands on the
machine 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.
ƔDo not overreach. This helps prevent unintended tip
contact and enables better control of the pruner in
unexpected situations.
ƔOnly use replacement bars and chains specified by
the manufacturer. Incorrect replacement bars and
FKDLQVPD\FDXVHFKDLQEUHDNDJHDQGRUNLFNEDFN
ƔSharpening 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.
ŶDo not use on a ladder or unstable support. Always cut
with both feet on solid ground to prevent being pulled
off balance.
ŶTo protect yourself from electrocution, do not operate
within 10 m of overhead electrical lines.
ŶBeware of falling branches or those which rebound after
hitting the ground.
ŶUse 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.
ŶWhen 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.
ŶIf 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.
ŶIf 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.

OPERATION – PRUNING
ŶStudy 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.
ŶNever stand under the branch to be pruned.
ŶPruned 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.
ŶEnsure that the falling branch is not a danger to
yourself, bystanders or property including utility cables.
ŶNever operate the tool with the pole at an angle of
greater than 60° from the horizontal.
ŶNever operate the pruner with the cutting means closer
than 10 m from overhead power lines.
ŶDo not force the tool, let the chain do the work at its
own speed.
ŶDo not try to cut the branch too close to the tree trunk.

4
Leave about 15 cm from the trunk to the cut.
ŶRest 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.
ŶSmall branches which are both thin in diameter and not
heavy can be cut with one cut using the bottom of the
saw bar.
ŶFor 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
MRLQWKHILUVWFXW
ŶConsider pruning large branches in manageable
sections rather than as a whole.
ŶNever try to restart a previous cut with the chain and
bar in the earlier cut. Always start a new cut. This will
