OPERATING INSTRUCTIONS
Thank you for buying a Ryobi power tool. Each Ryobi
power tool is carefully tested and subjected to strict quality
controls by TTI quality assurance. Nevertheless, the
service life of a power tool depends to a great extent on
you. Please observe the information contained in these
instructions and enclosed documentation. The more
careful you treat your Ryobi power tool, the longer it will
provide dependable service.
GENERAL POWER TOOL SAFETY WARNINGS
WARNING
Reading the operating instructions will
reduce the risk of injury.
WARNING
Read all safety warnings and 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.
WORK AREA SAFETY
a. Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
b. Do not operate power tools in explosive atmospheres,
such as in the presence of ammable liquids, gases or
dust. Power tools create sparks which may ignite the
dust or fumes.
c. Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
a. 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. Unmodied plugs
and matching outlets will reduce risk of electric shock.
b. 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.
c. Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
d. Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool. Keep
the cord away from heat, oil, sharp edges or moving
parts. Damaged or entangled cords increase the risk
of electric shock.
e. 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.
f. If operating a power tool in a damp location is
unavoidable, use a supply protected by a residual
current device (RCD). Use of an RCD reduces the risk
of electric shock.
NOTE: The term “residual current device (RCD)” may
be replaced by the term “ground fault circuit interrupter
(GFCI)” or “earth leakage circuit breaker (ELCB)”.
PERSONAL SAFETY
a. 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 inuence
of drugs, alcohol medication. A moment of inattention
while operating power tools may result in serious
personal injury.
b. Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust masks,
nonskid safety shoes, hard hats or hearing protection
used for appropriate conditions will reduce personal
injuries. Ryobi advise the use of chain saw clothing
complying to class 1 (use for chain saws).
c. Prevent unintentional starting. Ensure the switch is
in the off-position before connecting to power source
and, picking up or carrying the tool. Carrying power
tools with your nger on the switch or energising
power tools that have the switch on invites accidents.
d. 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.
e. Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool
in unexpected situations.
f. 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.
POWER TOOL USE AND CARE
a. 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.
b. 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.
c. Disconnect the plug from the power source before
making any adjustments, changing accessories, or
storing power tools. Such preventive safety measures
reduce the risk of starting the power tool accidentally.
2
English
d. 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.
e. 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.
f. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
g. Use the power tool and accessories 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
Have your power tool serviced by a qualied repair person
using only identical replacement parts. This will ensure
that the safety of the power tool is maintained.
If the replacement of tine supply cord is necessary, this
has to be done by the manufacturer or his agent in order
to avoid a safety hazard.
OTHER GENERAL WARNINGS

b. That extension cord is properly wired and in good
electrical condition.
c. That the wire size is large enough for the AC power
rating of the chain saw.
CHAIN SAW SAFETY WARNINGS-SPECIAL
SAFETY INSTRUCTIONS
■Keep all parts of the body away from the saw chain
when the chain saw is operating. Before you start the
chain saw, make sure the saw chain is not contacting
anything. A moment of inattention while operating
chain saws may cause entanglement of your clothing
or body with the saw chain.
■Always hold the chain saw with your right hand
on the rear handle and your left hand on the front
handle. Holding the chain saw with a reversed hand
configuration increases the risk of personal injury and
should never be done.
■Wear safety glasses and hearing protection. Further
protective equipment for head, hands, legs and feet
is recommended. Adequate protective clothing will
reduce personal injury by flying debris or accidental
contact with the saw chain.
■Do not operate a chain saw in a tree. Operation of a
chain saw while up in a tree may result in personal
injury.
■Always keep proper footing and operate the chain saw
3
English
only when standing on fixed, secure and level surface.
Slippery or unstable surfaces such as ladders may
cause a loss of balance or control of the chain saw.
■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 chain saw out of control.
■Use extreme caution when cutting brushes and
saplings. The slender material may catch the saw
chain and be whipped toward you or pull you off
balance.
■Carry the chain saw by the front handle with the chain
saw switched off and away from your body. When
transporting or storing the chain saw always fit the
guide bar cover. Proper handling of the chain saw will
reduce the likelihood of accidental contact with the
moving saw chain.
■Follow instructions for lubrication, chain tensioning
and changing accessories. Improperly tensioned or
lubricated chains may either break or increase the
chance for kickback.
■Keep handles dry, clean, and free from oil and grease.
Greasy, oily handles are slippery and can causing the
loss of control.
■Cut wood only. Do not use chain saw for purposes
not intended. For example: do not use the chain saw
for cutting plastic, masonry or non-wood building
materials. Use of the chain saw for operations different
than intended can result in a hazardous situation.
■Causes and operator prevention of kickback
a. 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.
b. Tip contact in some cases may cause a sudden
reverse reaction, kicking the guide bar up and back
towards the operator.
c. Pinching the saw chain along the top of the guard
bar may push the guide bar rapidly back towards the
operator.
d. Either of these reactions may cause you to lose control
of the saw which could result in serious injury. Do not
rely exclusively upon the safety devices built into your
saw. As a chain saw user, you should take several
steps to keep your cutting jobs free from accident or
Injury.
e. 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:
1. Maintain a rm grip, with thumbs and ngers encircling
the chain saw handles, with both hands on the saw
and position your body and arm to allow you to resist
kickback force. Kickback forces can be controlled by
the operator, if proper precautions are taken. Do not
let go of the chain saw.
2. Do not overreach and do not cut above shoulder
height. This helps to prevent unintended tip contact
and enables better control of the chain saw in
unexpected situations.
3. Only use replacement bars and chains specied by
the manufacturer. Incorrect replacement bars and
chains may cause chain breakage and/or kickback.
4. Follow the manufacturer’s sharpening and maintenance
instructions for the saw chain. Decreasing the depth
gauge height can lead to increased kickback.
■It is recommended to use a residual current device
with a tripping current of 30mA or less.
■Ensure that the power cord and the extension cord of
the chain saw cannot become entangled in branches
or any other objects during the usage of the chain saw.
■If you are an unexperienced user of the chain saw, you
should practice cutting logs on a saw-horse or cradle
before using the chain saw without these supporting
tools.
■The chain saw has a high starting current and
should be connected to a robust power supply. The
chain saw should be connected to a power source
with an impedance of Zsysmax=0.12+0.08j or less.
Please consult your electricity provider or authority if
necessary.

SPECIAL PRODUCT FEATURES
■The product is using a special safety wrap-spring
chain break mechanism to stop the chain within one
tenth of a second if the chain brake is engaged or the
trigger is released.
■The saw chain’s safety drive links are designed to
reduce the risk of kickback.
■Large chain brake element. In case of a “kickback,
the chain brake is pushed forward” by the back of the
operator’s hand and trips the quick brake of the chain
saw.
■The lock-off Switch with lock to protect against
unintentional start of the chain saw.
■The unique Ryobi Live tool indicator™ indicate the
good connection with the power supply.
COMMISSIONING
Assembling the chain bar and saw chain
Pull the mains plug out of the socket. Wear
protective gloves.
■Unscrew the knob w/nut and remove the sprocket
cover. (Fig. 3)
■The saw chain should face in the direction of chain
rotation. If they face backwards, turn the loop over.
(Fig. 4)
■Place the chain drive links into the bar groove. (Fig. 5)
■Position the chain so there is a loop at the back of
the bar.
■Hold the chain in position on the bar and place the
loop around the sprocket and make sure it is correctly
mounted. (Fig. 6)
■Swing the chain tension adjust knob, turn the chain
tensioning bolt clockwise until the saw chain is
correctly tensioned. While the bolt is being tightened,
the chain bar must then be pushed upwards, check
chain tension again, do not tension the chain too
tightly (Fig. 7)
■Replace the sprocket cover on top and tighten gently
with the knob w/nut.
Note: the saw chain is correctly tensioned if, in the middle
of the cutter, it can be lifted 3mm to 4mm from the cutter
upper edge. Starting the saw again with a new saw chain,
allow it to run in for 2~3 minutes.
WARNING:
After the run-in time, check the chain tension and
retighten the chain if necessary.
Chain&Bar lubricant
The chain saws are delivered without any oil in the oil tank.
Prior to initial operation of the machine, the oil tank must
be lled with lubricating oil.
Ryobi bar and chain lubricant permits chain saw operation
at temperatures as low as -15°C.
To rell the chain & bar lubricant the cap on top of the oil
tank needs to be removed. When lling the oil in, ensure
that no dirt gets into the oil tank. The oil level can be
monitored at the oil sight gauge. One lling of the oil tank
(capacity 0.2l) is sufcient for 25~40 minutes chain saw
operation.
CHECKING CHAIN LUBRICATION
If the saw chain is running dry (i.e. without lubricant), the
cutter and saw chain can be damaged. It is therefore
essential to check the oil level in the oil sight gauge
frequently and every time before starting to use the chain
saw.
WARNING:
Never work without chain lubrication!
To prevent dirt getting inside the tank, clean the oil tank
cap before opening. Check the contents of the oil tank
during sawing work by checking the oil gauge. Close the
oil tank cap tightly and wipe away any spills.
CHAIN BRAKE
The integrated chain brake brings the saw chain to a
standstill within 1/10 of a second if:
■The chain brake in front is pushed to its forward
(engaged) position or during work with the chain
saw with the back of the operator’s hand (due to a
kickback) pushing the chain brake forward, or
■The chain saw is switched off by releasing the trigger
If the chain brake is engaged (i.e. the chain brake guard
is pushed to the front) do not try to start the chain saw or
actuate the trigger switch.
WARNING:
Before operating the chain saw, always check
that the chain brake is in perfect working order
(by actuating the hand protection and releasing
the trigger). Have the machine repaired if braking
time is lengthened.
MAINS CONNECTION
WARNING:
Before plugging in, check to see that the rated
mains voltage and mains frequency, as stated on
the rating label, match your power supply.
9
English
WARNING:
Prior to starting work, check the mains connection
cable and extension cable for damage. Only use
mains connection cables and extension cables in
perfect condition.
WARNING:
The electrical system to which the chain saw is
connected should be equipped with a differential
current safety switch (with a max. of 30mA release
current).
It is advisable to use the cord retainer in the back handle
of the chain saw to avoid accidental disconnection of the
power supply.
BEFORE OPERATION
In order to prevent kickback, please follow these safety
instructions:
■Never cut with the tip of the chain bar! Be careful when
continuing cuts you are already working on!
■Always start cuts with the chain saw already running.
■Make sure that the saw chain is always properly
sharpened.
■Never cut through more than one branch at a time!
When lopping off branches, be careful not to touch any
other branches.
a. When cross-cutting, pay attention to trunks standing
very close to each other. If possible use a sawing
trestle.
TRANSPORTING THE CHAIN SAW
Before transporting the chain saw, always remove the
plug from the power socket and slide the chain cover over
the bar and chain. If several cuts are to be performed with
the chain saw, the saw must be switched off between cuts.
CHAIN GUARD (FIG. 2)
The chain cover must be clipped onto the chain and bar
as soon as the sawing work has been completed and
whenever the machine has to be transported.
OPERATION
WARNING:
Wear eye, ear and body clothing protection while
using your saw. Ensure the oil tank is full before
use.
■Releasing the chain brake.
To be able to use the chain saw again, the saw chain
must be unlocked, firstly switch off the saw release
the on/off switch completely and then pull the chain
brake back towards the back of the chain saw until it
locks into place. The chain will now move when it is
switched on.
■Holding the chain saw (Fig. 8)
Always grip both handles with the thumbs and fingers
encircling the handles. Ensure that your left hand is
holding the handle so that your thumb is underneath.
■Using the chain saw
Always be sure of your footing and hold the chain saw
firmly with both hands while the motor is running.
■Felling a tree (Fig. 9)
When bucking and felling operations are being
performed by two or more persons at the same time,
the felling operation 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
utility company should be notified immediately.
The chain saw operator should keep on the uphill side
of the terrain as the tree is likely to roll or slide downhill
after it is felled an escape path
An escape path should be planned and cleared as
necessary before cuts are started. The escape path
should extend back and diagonally to the rear of
expected line of fall as illustrated in Fig. 9.
Before felling is started, consider the natural lean of
the tree, the location of larger branches and the wind
direction to judge which may the tree will fall.
Remove dirt, stones, loose bark, nails, stapes and wire
from the tree.
■Notching undercut (A notch cut in a tree to direct the
fall) (Fig. 10)
Make the notch 1/3 the diameter of the tree,
perpendicular to the direction of falls. Make the lower
horizontal notching cut first, this will help to avoid
pinching of either the saw chain or the guide bar when
the second notch is being made.
■Felling back cut (the final cut in a tree felling operation,
made on the opposite side of the tree from the notching
undercut) (Fig. 10)
Make the felling back cut at least 50mm 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 cut gets close to the hinge, the tree should
begin to fall. If there is any chance that the tree may
10
English
not fall in the 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 off all. When the tree begins to fall
remove the chain saw from the cut, stop the motor,
put the chain saw down, and then use the retreat path
planned. Be alert for overhead limbs falling and watch
your footing.
■Limbing a tree (Fig. 11)
Limbing is 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 one cut.
Branches under tension should be cut from the bottom
up, to avoid binging the chain saw.
■Bucking a log (Fig.12 -15) Bucking is cutting a log into
lengths. It is important to make sure your footing is
firm 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 simple direction for easy cutting:
a. When the log is supported along the entire length, it is
cut from the top (overbuck). (Fig.12)
b. When the log is supported on one end, cut 1/3 of the
diameter from the underside (underbuck). Then make
the nished cut by overbucking to meeting the rst cut.
(Fig. 13)
c. When the log is supported on both ends, cut 1/3 of
that diameter from the top(overbuck). Then make the
nished cut by underbucking the lower 2/3 to meet the
rst cut. (Fig. 14)
d. 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 chain
saw handles. (Fig. 15).
Do not let the chain contact the ground. After completing
the cut, wait for the saw chain to stop before you move
the chain saw. Always stop the motor before moving from
tree to tree.
MAINTENANCE
(Fig. 16-21)
CHAIN SHARPENING
When the chain penetrates into wood with difcultly, it
needs sharpening as follows:
■Put the chain under tension.
■Fasten the bar in a vice so that the chain can slide.
■Fasten the file to the file holder and place it on cutter
at a 35° angle.
■File with forward strokes only until all the worn out part
of the cutting edge is taken away.
■Count the number of strokes given to the cutter taken
as a reference basis and file away for the same
number of strokes on all other cutters.
■If after sharpening a few times, the depth gauge
protrudes from the template, you must reset its level
use a flat file.
■Finally, round off the depth gauge.
NOTE: We advise you to have the deep or important
sharpening carried out by a service agent who is equipped
with electric sharpener.
GUIDE BAR MAINTENANCE
■When you have finished working, clean out the groove
and the oil passages, with a scraping hook.
■Periodically trim the sides of rails using a flat file.
■If not done in the long run, the featheredges might
