IMPORTANT SAFETY INSTRUCTIONS
The purpose of safety rules is to attract your
attention to possible dangers. The safety symbols
and the explanations with them, require your
careful attention and understanding. The safety
warnings do not by themselves eliminate any
danger. The instruction or warnings they give are
not substitutes for proper accident prevention
measures.
SAFETY ALERT SYMBOL. Indicates
danger, caution or warning. May be used
in conjunction with other symbols or
pictures.
Failure to obey a safety warning can result in
serious injury to yourself or to others. Always follow
the safety precautions to reduce the risk of fire,
electric shock and personal injury.
Do not attempt to operate this tool until you have
read thoroughly and completely understood the
safety rules, etc. contained in this manual. Failure
to comply can result in accidents involving fire,
electric shock or serious personal injury. Save this
Owners Operating Manual and review it frequently
for continual safe operation and for instructing
others who may use this tool.
INTENDED USE
The product is only intended for use outdoors. For
safety reasons the product must be adequately
controlled by using two-handed operation at all
times.
The product is designed for cutting branches,
trunks, logs and beams of a diameter determined
by the cutting length of the guide bar. It is only
designed to cut wood. It is only to be used in
domestic application by adults who have received
adequate training on the hazards and preventative
measures/actions to be taken whilst using it.
Do not use the product for any purpose not listed
above. It is not to be used for professional tree
services. The product is not to be used by children
or by persons not wearing adequate personal
protective equipment and clothing.
WARNING
To reduce the risk of injury, the user must
read and understand the operator’s
manual.
WARNING
Chainsaws are potentially dangerous
tools. Accidents involving the use of
chainsaws often result in loss of limbs or
death. It is not just the chainsaw that is
the hazard. Falling branches, toppling
trees, rolling logs can all kill.
Diseased or rotting timber poses
additional hazards. You should assess
your capability of completing the task
safely. If there is any doubt, leave it to a
professional tree surgeon.
CHAINSAW SAFETY WARNINGS
Keep all parts of the body away from the saw chain
when the chainsaw is operating. Before you start
the chainsaw, make sure the saw chain is not
contacting anything. A moment of inattention while
operating chainsaws may cause entanglement of
your clothing or body with the saw chain.
Always hold the chainsaw with your right hand on
the rear handle and your left hand on the front
handle. Holding the chainsaw with a reversed hand
configuration increases the risk of personal injury
and should never be done.
Hold the power tool by gripping surface only,
because the saw chain may contact hidden wiring
or its own cord. Saw chains contacting a “live” wire
may make exposed metal parts of the power tool
“live” and could give the operator an electric shock.
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 chainsaw in a tree. Operation of a
chainsaw while up in a tree may result in personal
injury.
Always keep proper footing and operate the
chainsaw 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 chainsaw.
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 chainsaw out of
control.

3
IMPORTANT SAFETY INSTRUCTIONS
Use extreme caution when cutting brush and
saplings. The slender material may catch the saw
chain and be whipped toward you or pull you off
balance.
Carry the chainsaw by the front handle with the
chainsaw switched off and away from your body.
When transporting or storing the chainsaw always
fit the guide bar cover. Proper handling of the
chainsaw will reduce the likelihood of accidental
contact with the moving saw chain.
Follow instructions for lubricating, chain tensioning
and changing accessories. Improperly tensioned or
lubricated chain may either break or increase the
chance for kickback.
Keep handles dry, clean, and free from oil and
grease. Greasy, oily handles are slippery causing
loss of control.
Cut wood only. Do not use chainsaw for purposes
not intended. For example: do not use chainsaw for
cutting plastic, masonry or non-wood building
materials. Use of the chainsaw for operations
different than intended could result in a hazardous
situation.
CAUSES AND OPERATOR PREVENTION OF
KICKBACK
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 saw which could result in serious
personal injury. Do not rely exclusively upon the
safety devices built into your saw. As a chainsaw
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
follows:
Maintain a firm grip, with thumbs and fingers
encircling the chainsaw handles, with both hands
on the saw 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 chainsaw.
Do not overreach and do not cut above shoulder
height. This helps prevent unintended tip contact
and enables better control of the chainsaw 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.
Follow the manufacturer’s sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to
increased kickback.
ADDITIONAL CHAINSAW SAFETY WARNINGS
It is recommended to cut logs on a saw-horse or
cradle when operating the product the first time.
Ensure all guards, handles and spiked bumper are
properly fitted and are in good condition.
Persons using this chainsaw should be in good
health. The chainsaw is a heavy unit so the
operator requires to be physically fit. The operator
should be alert, have good vision, mobility, balance
and manual dexterity. If there is any doubt, do not
operate the chainsaw.
Do not start using the product until you have a
clear work area, secure footing, and a planned
retreat path away from the falling tree.
Beware of the emission of lubricant mist and saw
dust. Wear a mask or respirator if required.
Electric power should be supplied via a residual
current device (RCD) with a tripping current of not
more than 30 mA.
If the power cable becomes damaged, you must
return the machine to an authorised service centre
for repair or replacement.
Always keep the power cable tidy and away from
the area of cutting. Apart from the danger of
electrocution, untidy cables cause falls and trips.
Do not cut vines and/or small undergrowth (less
than 75 mm in diameter).

IMPORTANT SAFETY INSTRUCTIONS
Always hold the chainsaw with both hands when
operating the saw. Use a firm grip with thumbs and
fingers encircling the chainsaw handles. Right hand
must be on the rear handle and left hand on the
front handle.
Before starting the tool, make sure the saw chain is
not contacting any object.
Do not modify your tool in any way or use it to
power any attachments or devices not
recommended by the manufacturer for your saw.
There should be a first-aid kit containing large
wound dressings and a means to summon
attention (e.g., whistle) close to the operator. A
larger more comprehensive kit should be
reasonably nearby.
The operator may be tempted to remove the
helmet if there is no danger of falling objects in the
work area, but remember the helmet, particularly
with the mesh visor, can help reduce the potential
for injury to the face and head if kickback occurs.
An incorrectly tensioned chain can jump off the
guide bar and could result in serious injury or
fatality. The length of chain depends on the
temperature. Check the tension frequently.
You should get used to your new chainsaw by
making simple cuts on securely supported wood.
Do this whenever you have not operated the saw
for some time.
To reduce the risk of injury associated with
contacting moving parts, always stop the motor,
apply chain brake, remove the plug from the power
socket and 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
The size of the work area depends on the job being
performed as well as the size of the tree or work
piece involved. For example, felling a tree requires
a larger work area than making other cuts, i.e.,
bucking cuts, etc. The operator needs to be aware
and in control of everything happening in this work
area.
Do not cut with your body in line with the guide bar
and chain. If you do experience kickback this will
help prevent the chain coming into contact with
your head or body.
Do not use a back and forward sawing motion, let
the chain do the work, keep the chain sharp and
don’t try to push the chain through the cut.
Do not put pressure on the saw at the end of the
cut. Be ready to take on the weight of the saw as it
cuts free from the wood. Failure to do so could re-
sult in possible serious personal injury.
Do not stop the saw in the middle of a cutting
operation. Keep the saw running until it is already
removed from the cut.
PUSH & PULL
The reaction force is always opposite to the
direction the chain is moving. Thus, the operator
must be ready to control the tendency for the
machine to pull away (forward motion) when cutting
on the bottom edge of the bar and the push
backwards (towards the operator) when cutting
along the top edge.
SAW JAMMED IN THE CUT
Stop the chainsaw and make it safe. Do not try to
force the chain and bar out of the cut as this is
likely to break the chain which may swing back and
strike the operator. This situation normally occurs
because the wood is incorrectly supported and
forcing the cut to close under compression thereby
pinching the blade. If adjusting the support does
not release the bar and chain, use wooden wedges
or a lever to open the cut and release the saw.
Never try to start the chainsaw when the guide bar
is already in a cut or kerf.
PERSONAL PROTECTIVE E UIPMENT
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 chainsaw:
SAFETY HELMET
Should comply with EN 397 and be CE marked.
HEARING PROTECTION
Should comply with EN 352-1 and be CE marked.
EYE AND FACE PROTECTION
Should be CE marked and comply with EN 166 (for
safety glasses) or EN 1731 (for mesh visors).

5
IMPORTANT SAFETY INSTRUCTIONS
GLOVES
Should comply with EN381-7 and be CE marked.
LEG PROTECTION (CHAPS)
Should comply with EN381-5, be CE marked and
provide all-round protection.
CHAINSAW SAFETY BOOTS
Should comply with EN ISO 20345:2004 and be
marked with a shield depicting a chainsaw to show
compliance with EN 381-3. (Occasional users may
use steel toe-cap safety boots with protective
gaiters which conform to EN 381-9 if the ground is
even and there is little risk of tripping or catching on
undergrowth).
CHAINSAW JACKETS FOR UPPER BODY
PROTECTION
Should comply with EN 381-11 and be CE marked.
RESIDUAL RISKS
Even when the product is used as prescribed, it is
still impossible to completely eliminate certain
residual risk factors. The following hazards may
arise in use and the operator should pay special
attention to avoid the following:
• Injury caused by vibration. Always use the right
tool for the job, use designated handles and
restrict working time and exposure.
• Exposure to noise can cause hearing injury.
Wear ear protection and limit exposure.
• Contact with exposed saw teeth of the chain
(cutting hazards).
• Unforeseen, abrupt movement or kickback of
the guide bar (cutting hazards).
• Parts ejected from the saw chain
(cutting/injection hazards).
• Thrown out pieces of the work piece
(wood chips, splinters).
• Inhalation of saw dust and particles.
• Skin contact with lubricant/oil.
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 fingers, 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 unit 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. imit the amount of
exposure per day.
• Protective gloves available from professional
chainsaw retailers are designed specifically for
chainsaw use which give protection, good grip
and also reduce the effect of handle vibration.
These gloves should comply with EN381-7 and
must be CE marked.
If you experience any of the symptoms of this
condition, immediately discontinue use and see
your doctor about these symptoms.
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.
GENERAL SAFETY RULES

IMPORTANT SAFETY INSTRUCTIONS
c) Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
2) 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. Unmodified 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 ab se the cord. Never se the cord for
carrying, p lling or npl gging the power tool.
Keep 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 o tdoors, se an
extension cord s itable for o tdoor se. Use of
a cord s itable for o tdoor se red ces the risk
of electric shock.
f) If operating a power tool in a damp location is
navoidable, se a resid al c rrent device
(RCD) protected s pply. Use of an RCD
red ces the risk of electric shock.
3) 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 influence of drugs, alcohol or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
b) Use personal protective equipment. Always
wear eye protection. Safety equipment such as
dust mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate
conditions will reduce personal injuries.
c) Avoid accidental starting. Ensure the switch is
in the off position before plugging in. Carrying
power tools with your finger on the switch or
plugging in 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. oose clothes,
jewellery or long hair can be caught in moving
parts.
g) If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
these devices can reduce dust related hazards.
4) 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.
d) Store idle power tools out of the reach of

SAFETY DEVICES
LOW KICK-BACK SAW CHAIN
A low-kick-back saw chain helps to reduce the
possibility of a kickback event.
The rakers (depth gauges) ahead of each cutter
can minimize the force of a kick-back reaction by
preventing the cutters from digging in too deeply.
Only use replacement guide bar and chain
combinations recommended by the manufacturer.
As saw chains are sharpened, they lose some of
the low kickback qualities and extra caution is
required. For your safety, replace saw chains when
cutting performance decreases.
SPIKED BUMPER
The integral bumper spike may be used as a pivot
when making a cut. It helps to keep the body of the
chainsaw steady while cutting. When cutting, push
the machine forward until the spikes dig into the
edge of the wood, then by moving the rear handle
up or down in the direction of the cutting line it can
help ease the physical strain of cutting.
GUIDE BARS
Generally, guide bars with small radius tips have
somewhat lower potential for kick-back. You should
use a guide bar and matching chain which is just
long enough for the job.
onger bars increase the risk of loss of control
during sawing. Regularly check the chain tension.
When cutting smaller branches (less than the full
length of the guide bar) the chain is more likely to
be thrown off if the tension is not correct.
CHAIN BRAKE
Chain brakes are designed to quickly stop the
chain rotating. When the chain brake lever/hand
guard is pushed towards the bar, the chain should
stop immediately. A chain brake does not prevent
kick-back. It only lowers the risk of injury should the
chain bar contact the operator’s body during a
kick-back event. The chain brake should be tested
before each use for correct operation in both the
run and brake positions.
UNPACKING
CAUTION. This packaging contains
sharp objects. Take care when
unpacking. Remove the machine,
together with the accessories supplied, from the
packaging. Check carefully to ensure that the
machine is in good condition and account for all the
accessories listed in this manual. Also make sure
that all the accessories are complete.
If any parts are found to be missing, the machine
and its accessories should be returned together in
their original packaging to the retailer. Do not throw
the packaging away, keep it safe throughout the
guarantee period, then recycle if possible,
otherwise dispose of it by the proper means. Do
not let children play with empty plastic bags due to
the risk of suffocation.

ASSEMBLY
ASSEMBLING SAW CHAIN AND GUIDE BAR
Disconnect the mains plug. Wear protective gloves.
Unscrew the guide bar locking knob (1) and
remove the sprocket cover (2), Fig.1.
The saw chain should face in the direction of chain
rotation. If they face backwards, turn the loop over.
Place the chain drive links into the bar groove,
Fig.2.
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 drive sprocket, Fig.3. ower the
bar so that the bolt goes through the hole in the
attached chain tension assembly (3). You may
need to rotate this assembly so the bolt and hole
align. You may rotate this assembly again to apply
some tension to the chain which will help keep it in
place.
Replace the sprocket cover and turn the guide bar
locking knob until nearly tight, Fig.3 (4).
Turn the chain tension adjustment ring until the saw
chain is properly tensioned, Fig.4. The guide bar
must then be pushed upwards, check chain tension
again, do not tension the chain too tight.
After the chain is well-tensioned, tighten the knob
again.

ASSEMBLY
ADJUSTING THE CHAIN TENSION
oosen the guide bar locking knob slightly by
turning it counterclockwise.
To increase the chain tension, turn the chain
tensioner adjustment ring clockwise and check the
chain tension frequently. To reduce the chain
tension, turn the chain tensioner adjustment ring
counterclockwise and check the chain tension
frequently.
The chain tension is correct when the gap between
the cutter in the chain and the bar is between
3-4mm. Pull the chain in the middle of the lower
side of the bar downwards (away from the bar) and
measure the distance between the bar and the
chain cutters, Fig.5.
Tighten the guide bar locking knob by turning it
clockwise.

ADDING CHAIN LUBRICATING OIL
WARNING. Never work without chain
lubricant. If the saw chain is running
without lubricant, guide bar and saw
chain can be damaged. It is therefore
essential to check the oil level in the oil
level gauge frequently and every time
before starting to use the chain saw.
CHAIN LUBRICANT
• Proper lubrication of the chain while in
operation reduces the friction between the
chain and the guide bar and assures a longer
tool life. Use only special chain oil of a high
quality for this purpose.
• Do not use any waste or reclaimed oil as this
could cause various problems with the oil
pump.
SAW CHAIN / BAR LUBRICATION
Adequate lubrication of the saw chain is essential
at all times to minimize friction with the guide bar.
Never starve the bar and chain of oil. Running the
saw with too little oil will decrease cutting efficiency,
shorten saw chain life, cause rapid dulling of chain,
and cause excessive wear of bar from overheating.
Too little oil is evidenced by smoke, bar
discolouration or pitch build-up. New chains/bars
should be lubricated by hand before starting.
Clear surface around the oil cap to prevent
contamination.
Unscrew and remove the cap from the oil tank,
Fig.6.
Pour oil into the oil tank and monitor the oil level
gauge. Ensure that no dirt enters the oil tank while
filling. The manufacturer recommends you use only
Ryobi chainsaw lubricating oil. (Available from your
authorised Ryobi service centre)
Put the oil cap back on and tighten it up. Wipe
away any spillage.
One full oil tank will enable you to use the saw for
20-40 minutes.

OPERATION
CHECKING AND OPERATING CHAIN BRAKE
Engage the chain brake by rotating your left hand
around the front handle. Allow the back of your
hand to push the chain brake lever/hand guard
toward the bar while the chain is rotating rapidly.
Be sure to maintain both hands on the saw handles
at all times.
Reset the chain brake back into the Run position
by grasping the top of the chain brake lever/hand
guard and pulling toward the front handle until you
hear a click.
WARNING. If the chain brake does not
stop the chain immediately, or if the
chain brake will not stay in the run
position without assistance, take the saw
to an authorised service centre for repair
prior to use.
OPERATION
The following section on the operation of the chain
saw is a general guide only. The use of a chain saw
by an inexperienced person can be extremely
dangerous. If you are unsure, please seek the
assistance of a professional or get suitable training
before using the chain saw.
WARNING. Before every use check the
operation of the chain break and oil
pump.
BUCKING SPIKES
The chainsaw has bucking spikes (Fig.10-A) to
assist with cutting and reduce the chance of
kickback. Keep the bucking spikes touching the
wood when cutting will help prevent any pinching or
kick-back.
BUCKING
Bucking is cutting a log into lengths for easier
handling. To saw a log lying on the ground, first
saw halfway, then roll the log over and cut from the
opposite side (Fig.11). To saw the end of a log
supported off the ground, first saw up from the
bottom one-third through the log then finish by
sawing down from the top. To saw a log in the
middle of two supports holding it off the ground,
first saw down from the top one-third through the
log then finish by sawing up from the bottom
(Fig.12).When bucking on a slope, always stand on
the uphill side.
WARNING. Be careful that the chain
does not cut into the ground when
bucking as this causes rapid dulling of
the chain.

LIMBING
imbing is the process of removing the branches
from a fallen tree. Check the direction in which a
branch will bend before cutting it. Always cut on the
opposite side to the bending direction so that the
guide bar is not pinched in the cut. For large limbs
that cannot be removed in one cut, make an initial
cut from the bent side and finish by sawing from
the opposite direction (Fig.19). Do not remove
limbs that are supporting the fallen tree on the
ground until the tree has been cut into lengths.
WARNING. Always keep a well balanced
stance. Do not stand on the log. Be alert
to the fact that the log may roll over.
When working on a slope, always stand
on the uphill side of the log.
PRUNING
Pruning is the removal of a limb or branch from a
standing tree.
WARNING. Do not use an unstable
foothold or ladder. Do not overreach. Do
not saw above shoulder height. Always
use both hands to hold the saw. First cut
up from the bottom and finish down from
the top, Fig.14.
FELLING
Felling is the term for cutting down a tree. Small
trees up to 6-7 inches (15-18cm) in diameter are
usually cut in a single cut. arger trees require
notch cuts. Notch cuts determine the direction the
tree will fall.
WARNING. Do NOT fell trees unless you
have received the appropriate training.
A retreat path (Fig.15- A) should be
planned and cleared as necessary
before cuts are started. The retreat path
should extend back and diagonally to the
rear of the expected line of fall, as
illustrated.
NOTE: Direction of fall (Fig.21-B) is
controlled by the notching cut. Before
any cuts are made, consider the location
of larger branches and natural lean of
the tree to determine the way the tree
will fall.

OPERATION
GENERAL GUIDELINES FOR FELLING TREES
Normally felling consists of 2 main cutting opera-
tions, notching (Fig.16-C) and making the felling
cut (Fig.16-D).
Start making the upper notch cut (Fig.16-C) on the
side of the tree facing the felling direction
(Fig.16-E).
Be sure you don t make the lower cut too deep in-
tothe trunk.
The notch (Fig.16-C) should be deep enough to
create a hinge (Fig.16-F) of sufficient width and
strength. The notch should be wide enough to
direct the fall of the tree for as long as possible.
Use wooden or plastic wedges (Fig .17-A) to
prevent pinching the bar and chain (Fig.17-B) in the
cut. Wedges also control felling.
When diameter of wood being cut is greater than
the bar length, make 2 cuts as shown (Fig.18).
WARNING. Before making the final cut,
always recheck the area for bystanders,
animals or obstacles.
WARNING: Never saw completely
through the trunk. Always leave a hinge
(Fig.16-F). The hinge guides the tree. If
the trunk is completely cut through,
control over the felling direction is lost.
Insert a wedge or felling lever in the cut
well before the tree becomes unstable
and starts to move. This will prevent the
bar from binding in the felling cut if you
have misjudged the falling direction.
Make sure no bystanders have entered
the range of the falling tree before you
push it over.
WARNING: As the felling cut gets close
to the hinge, the tree should begin to fall.
When tree begins to fall, remove saw
from cut, stop engine, put chain saw
down, and leave area along retreat path.

MAINTENANCE
SHARPENING THE CHAIN SAW
WARNING. We advise you to have deep
or important sharpening carried out by a
service agent who is equipped with an
electric sharpener.
When the chain penetrates into wood with difficulty,
it needs to be sharpened as follows:
1. Put the chain under tension.
2. Fasten the bar in a vice so that the chain can
slide (Fig.19)
3. File with forward strokes only until all the worn
out parts of the cutting edge is removed.
4. Count the number of strokes given to the cutter
as a reference basis and file away the same
number of strokes on all other cutters.
5. If after sharpening a few times, the depth
gauge protrudes from the template, you must
reset its level using a flat file. (Fig.20)
6. Finally round off the depth gauge. (Fig.21)
GUIDE BAR
The guide bar is subjected to especially severe
wear and tear at the nose and the bottom. To avoid
one-sided wear and tear, turn the guide bar over
every time you sharpen the chain.
1. When you have finished working, clean out the
groove and the oil passages, with a special
scraping hook. (Fig.22).
2. Periodically trim the sides of the rails using a
flat file. If not done in the long run the
“feathered edges” might break away and
damage the bar. (Fig.23)

MAINTENANCE
3. If one rail is higher than the other one, it is
necessary to make it even with a flat file and
then smooth them with a file or fine grain
abrasive paper. (Fig.24)
CHAIN TENSION
Check the chain tension frequently and adjust as
often as necessary to keep the chain snug on the
bar, if the chain is pulled down with the fingers at
the centre of the bar the gap between the chain
and the bar should be 3 to 4mm.
NEW CHAINS
A new chain will need to be readjusted after as few
as 5 cuts. This is normal during the break in period,
future adjustments will be required less often.
OIL PASSAGES
Oil passages on the bar should be cleaned to
ensure proper lubrication of the bar and chain
during operation.
NOTE. The condition of the oil passages can be
easily checked. If the passages are clear, the chain
will automatically give off a spray of oil within
seconds of starting the saw. Your saw is equipped
with an automatic oiler system.
