each use and frequently, especially a new chain.
moving parts, always stop the machine, disconnect
from the mains, 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
Kickback may occur when the nose or tip of the guide
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
built into your machine. As a pruner user, you should
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 unit.
Maintain 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.
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
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.
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. 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 tool are securely fastened before each use and at
frequent intervals.

OPERATION – PRUNING
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 tool with the pole at an angle of
greater than 60° from the horizontal.
Never operate the pruner with the cutting means closer
than 10 m from overhead power lines.
Do not force the tool, 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.
