Safety
General safety instructions
WARNING: Read the warning instructions
that follow before you use the product.
A chainsaw is a dangerous tool if used carelessly or
incorrectly and can cause serious injury or death. It
is very important that you read and understand the
contents of this operator’s manual.
Under no circumstances may the design of the
product be modified without the permission of the
manufacturer. Do not use a product that appears to
have been modified by others and always use
original accessories. Non-authorized modifications
and/or accessories can result in serious personal
injury or the death of the operator or others.
The inside of the muffler contain chemicals that may
be carcinogenic. Avoid contact with these elements
in the event of a damaged muffler.
Long term inhalation of the engine’s exhaust fumes,
chain oil mist and dust from sawdust can represent a
health risk.
This product produces an electromagnetic field
during operation. This field may under some
circumstances interfere with active or passive
medical implants. To reduce the risk of serious or
fatal injury, we recommend persons with medical
implants to consult their physician and the medical
implant manufacturer before operating this product.
The information in this operator's manual is never a
substitute for professional skills and experience. If
you get into a situation where you feel unsafe, stop
and seek expert advice. Contact your servicing
dealer or an experienced chainsaw user. Do not
attempt any task that you feel unsure of!
Safety instructions for operation
WARNING: Read the warning instructions
that follow before you use the product.
This top handle chainsaw is designed specifically for
tree surgery and maintenance in the tree. Due to the
special compact handle design (closely spaced
handles), there is an increased risk of losing control.
For this reason these special chainsaws should be
used only for work in a tree by persons who are
trained in special cutting and working techniques and
who are properly secured (lift bucket, ropes, safety
harness). Regular chainsaws (with wider spaced
handles) are recommended for all other cutting work
at ground level.
Working in a tree requires the use of special cutting
and working techniques which must be observed in
order to reduce the increased risk of personal injury.
Never work in a tree unless you have received
specific, professional training for such work,
including training in the use of safety and other
climbing equipment, such as harnesses, ropes,
belts, climbing irons, snap hooks, carabiners,
etcetera.
Never cut with the kickback zone at the tip of the
chainsaw guide bar.
Never attempt to catch falling sections or cut in the
tree when he/she is only secured with one rope.
Always use two secured lines.
During critical felling operations, hearing protectors
should be lifted immediately when the sawing is
completed so that sounds and warning signals can
be heard.
Before using a chainsaw you must understand the
effects of kickback and how to avoid them. See
instructions under the heading
What is kickback? on
page 18
.
Never use a product that is faulty. Carry out the
safety checks, maintenance and service instructions
described in this manual. Some maintenance and
service measures must be carried out by trained and
qualified specialists. See instructions under
Maintenance on page 20
Never use a product with visible damage to the
spark plug guard and ignition cable. A risk of
sparking arises, which can cause a fire.
Never use the product if you are fatigued, while
under the influence of alcohol or drugs, medication
or anything that could affect your vision, alertness,
coordination or judgement.
Do not use the product in bad weather such as
dense fog, heavy rain, strong wind, intense cold,
etcetera. Working in bad weather is tiring and often
brings added risks, such as icy ground,
unpredictable felling direction, etcetera.
Faulty cutting equipment or the wrong combination
of guide bar and saw chain increases the risk of
kickback! Only use the guide bar and saw chain
combinations we recommend, and follow the filing
instructions. See instructions under
Accessories on
page 34
Never start a chainsaw unless the bar, saw chain
and all covers are fitted correctly. See instructions
under the heading
Assembly on page 12
. Without a
4
308 - 004 - 27.09.2017
bar and saw chain attached to the chainsaw the
clutch can come loose and cause serious injury.
Do not drop start. This method is very dangerous
because you may lose control of the chainsaw.
Never start the product indoors. Exhaust fumes can
be dangerous if inhaled.
Observe your surroundings and make sure that there
is no risk of people or animals coming in contact with
or affect your control of the product.
Lack of concentration can lead to kickback if the
kickback zone of the bar accidentally touches a
branch, nearby tree or some other object.
Never use a chainsaw by holding it with one hand. A
chainsaw is not safely controlled with one hand; you
can cut yourself. Always have a secure, firm grip
around the handles with both hands.
Always hold the chainsaw firmly with your right hand
on the top handle and your left hand on the front
handle. Wrap your fingers and thumbs around the
handles. You should use this grip whether you are
right handed or left handed. This grip minimizes the
effect of kickback and lets you keep the chainsaw
under control. Do not let go of the handles!
Never use the chainsaw above shoulder height and
try not to cut with the tip of the bar.
Do not use a chainsaw in a situation where you
cannot call for help in case of an accident.
Sometimes chips get stuck in the clutch cover
causing the saw chain to jam. Always stop the
engine before cleaning.
If the saw chain jams in the cut: stop the engine!
Running an engine in a confined or badly ventilated
area can result in death due to asphyxiation or
carbon monoxide poisoning.
It is not possible to cover every conceivable situation
you can face when using a chainsaw. Always
exercise care and use your common sense. Avoid all
situations which you consider to be beyond your
capability. If you still feel uncertain about operating
procedures after reading these instructions, you
should consult an expert before continuing. Do not
hesitate to contact your dealer or us if you have any
questions about the use of the chainsaw. We will
willingly be of service and provide you with advice as
well as help you to use your chainsaw both efficiently
and safely. Attend a training course in chainsaw
usage if possible. Your dealer, forestry school or
your library can provide information about which
training materials and courses are available.

Personal protective equipment
WARNING: Read the warning instructions
that follow before you use the product.
Most chainsaw accidents happen when the saw
chain touches the operator. You must use approved
personal protective equipment whenever you use the
machine. Personal protective equipment cannot
eliminate the risk of injury but it will reduce the
degree of injury if an accident does happen. Ask
your servicing dealer for help in choosing the right
equipment.
Always wear personal protective equipment. Use
appropriate protections for your arms. Generally
clothes should be close-fitting without restricting your
freedom of movement. Regularly check the condition
of the personal protective equipment.
Wear an approved protective helmet.
Wear approved hearing protection. Long-term
exposure to noise can result in permanent hearing
impairment
Always wear protective glasses or a face visor to
reduce the risk of injury from thrown objects. A chain
saw is capable of throwing objects, such as wood
chips, small pieces of wood, etc, at great force. This
can result in serious injury, especially to the eyes.
Wear gloves with saw protection.
Wear trousers with saw protection.
Wear boots with saw protection, steel toe-cap and
non-slip sole.
Always have a first aid kit nearby.
Sparks can come from the muffler, the bar and chain
or other sources. Always have fire extinguishing
tools and a shovel available to help prevent forest
fires.
Safety devices on the product
WARNING: Read the warning instructions
that follow before you use the product.
In this section the product’s safety features and their
function are explained. For inspection and maintenance
see instructions under the heading
Examination,
maintenance and service of the product's safety
equipment on page 21
. See instructions under the
heading
Product overview GZ3500T on page 2
to find
where these parts are located on your product.
The life span of the machine can be reduced and the
risk of accidents can increase if product maintenance is
not carried out correctly and if service and/or repairs are
not carried out professionally. If you need further
information please contact your nearest servicing dealer.
WARNING: Never use a product with
defective safety components. Safety
equipment must be inspected and
maintained. See instructions under the
heading
Examination, maintenance and
service of the product's safety equipment on
page 21
. If your machine does not pass all
the checks, take the chainsaw to a servicing
dealer for repair.
Chain brake and front hand guard
Your chainsaw is equipped with a chain brake that is
designed to stop the saw chain if you get a kickback.
The chain brake reduces the risk of accidents, but only
you can prevent them.
WARNING:
Avoid situations where there is a
risk of kickback. Take care when using your
chainsaw and make sure the kickback zone
of the guide bar never touches any object.
6 308 - 004 - 27.09.2017
The chain brake (A) can either be activated manually (by
your left hand) or automatically by the inertia release
mechanism.
The brake is engaged when the front hand guard (B) is
pushed forwards.
A
B
B
This movement activates a spring-loaded mechanism
that tightens the brake band (C) around the engine drive
system (D) (clutch drum).
D
C
The front hand guard is not designed solely to activate
the chain brake. Another important feature is that it
reduces the risk of your left hand hitting the saw chain if
you lose grip of the front handle.
The chain brake must be engaged when the chainsaw is
started to prevent the saw chain from rotating.
Use the chain brake as a ”parking brake” when starting
and when moving over short distances, to reduce the
risk of moving chain accidentally hitting your leg or
anyone or anything close by.
To release the chain brake pull the front hand guard
backwards, towards the front handle.
Kickback can be very sudden and violent. Most
kickbacks are minor and do not always activate the
chain brake. If this happens you should hold the
chainsaw firmly and not let go.
The way the chain brake is activated, either manually or
automatically by the inertia release mechanism,
depends on the force of the kickback and the position of
308 - 004 - 27.09.2017
7
the chainsaw in relation to the object that the kickback
zone of the guide bar strikes. If you get a violent
kickback while the kickback zone of the guide bar is
farthest away from you the chain brake is designed to be
activated by the inertia in the kickback direction.
If the kickback is less violent or the kickback zone of the
guide bar is closer to you the saw chain brake will be
activated manually by the movement of your left hand.
In the felling position the left hand is in a position that
makes manual activation of the chain brake impossible.
With this type of grip, that is when the left hand is placed
so that it cannot affect the movement of the front hand
guard, the chain brake can only be activated by the
inertia action.
Common questions about kickback
Will my hand always activate the chain brake during
a kickback?
No. It takes a certain force to move the hand guard
forward. If your hand only lightly touches the front
hand guard or slips over it, the force may not be
enough to trigger the chain brake. You should also
maintain a firm grip of the chainsaw handles while
working. If you do and experience a kickback, your
hand may never leave the front handle and will not
activate the chain brake, or the chain brake will only
activate after the chainsaw has swung around a
considerable distance. In such instances, the chain
brake might not have enough time to stop the saw
chain before it touches you. There are also certain
positions in which your hand cannot reach the front
hand guard to activate the chain brake; for example,
when the saw chain is held in felling position.
Will my inertia activated chain brake always activate
during kickback in the event of a kickback?
No. First, your brake must be in working order.
Testing the brake is simple, see instructions under
the heading
Examination, maintenance and service
of the product's safety equipment on page 21
. We
recommend you do this before you begin each work
session. Second, the kickback must be strong
enough to activate the chain brake. If the chain
brake is too sensitive it would activate all the time,
which would be a nuisance.
Will my chain brake always protect me from injury in
the event of a kickback?
No. First, the chain brake must be in working order
to provide the intended protection. Second, it must
be activated during the kickback as described above
to stop the saw chain. Third, the chain brake may be
activated but if the guide bar is too close to you the
brake might not have enough time to slow down and
stop the saw chain before the chainsaw hits you.
WARNING:
Only you and proper working
technique can eliminate kickback and its
dangers.
Throttle trigger lockout
The throttle trigger lockout is designed to prevent
accidental operation of the throttle trigger. When you
press the throttle trigger lockout down (A) (in example
when you grasp the handle) it releases the throttle
trigger (B). When you let go of the handle, the throttle
trigger and the throttle trigger lockout both return to their
8
308 - 004 - 27.09.2017
default positions. This design locks the throttle trigger at
idle setting.
B
A
Chain catcher
The chain catcher is designed to catch the chain if it
snaps or jumps off. This should not happen if the chain
is properly tensioned (see instructions under the
heading
Assembly on page 12
) and if the bar and chain
are properly serviced and maintained (see instructions
under the heading
Operation on page 13
).
Vibration damping system
Your product is equipped with a vibration damping
system that is designed to minimize vibration and make
operation easier.
The product′s vibration damping system reduces the
transfer of vibration between the engine unit/cutting
equipment and the product′s handle unit. The body of
the chainsaw, including the cutting equipment, is
insulated from the handles by vibration damping units.
Cutting hardwoods (most broadleaf trees) creates more
vibration than cutting softwoods (most conifers). Cutting
with cutting equipment that is blunt or faulty (wrong type
or badly sharpened) will increase the vibration level.
WARNING: Overexposure to vibration can
lead to circulatory damage or nerve damage
in people who have impaired circulation.
Contact your doctor if you experience
symptoms of overexposure to vibration.
Such symptoms include numbness, loss of
feeling, tingling, pricking, pain, loss of
strength, changes in skin colour or condition.
These symptoms normally appear in the
fingers, hands or wrists. These symptoms
may be increased in cold temperatures.
Start/stop switch
Use the start/stop switch to switch off the engine.
Muffler
The muffler is designed to keep noise levels to a
minimum and to direct exhaust fumes away from the
user.
WARNING:
The exhaust fumes from the
engine are hot and may contain sparks
which can start a fire. Never start the
machine indoors or near combustible
material!
In areas with a hot, dry climate there is a high risk of
fires.
308 - 004 - 27.09.2017
9
WARNING: The muffler gets very hot during
and after use. This also applies during idling.
Be aware of the fire hazard, especially when
working near flammable substances and/or
vapours.
WARNING: Never use a saw without a
muffler, or with a damaged muffler. A
damaged muffler may substantially increase
the noise level and the fire hazard. Keep fire
fighting equipment handy.
Fuel safety
WARNING: Read the warning instructions
that follow before you use the product.
Make sure there is plenty of ventilation when
refuelling or mixing fuel (petrol and two-stroke oil).
Fuel and fuel vapour are highly flammable and can
cause serious injury when inhaled or allowed to
come in contact with the skin. For this reason
observe caution when handling fuel and make sure
there is adequate ventilation.
Take care when handling fuel and chain oil. Be
aware of the risks of fire, explosion and those
associated with inhalation.
Do not smoke and do not place any hot objects in
the vicinity of fuel.
Always stop the engine and let it cool for a few
minutes before refuelling.
When refuelling, open the fuel cap slowly so that any
excess pressure is released gently.
Tighten the fuel cap carefully after refuelling.
Never refuel the product while the engine is running.
Always move the product at least 3 m (10 ft) away
from the refuelling area and source before starting.
Min. 3m
(10 ft)
After refuelling, there are some situations where you
must never start the product:
If you have spilled fuel or chain oil on the product.
Wipe off the spillage and allow remaining fuel to
evaporate.
If you have spilled fuel on yourself or on your
clothes. Change your clothes and wash any part of
your body that has come in contact with fuel. Use
soap and water.
If the product leaks fuel. Regularly do a check for
leaks from the fuel cap and fuel lines.
Safety instructions for maintenance
Cutting equipment
This section describes how to choose and maintain your
cutting equipment in order to:
Reduce the risk of kickback.
Reduce the risk of the saw chain breaking or
jumping off the bar.
Obtain optimal cutting performance.
Extend the life of cutting equipment.
Avoid increasing vibration levels.
WARNING: Read the warning instructions
that follow before you use the product.
Faulty cutting equipment or the wrong combination
of bar and saw chain increases the risk of kickback!
Only use the bar/saw chain combinations we
recommend, and follow the filing instructions. See
instructions under the heading
Accessories on page
34
.
Always use protective gloves when you handle the
saw chain.
Any contact with a rotating saw chain can cause
extremely serious injuries.
Keep the chain’s cutting teeth properly sharpened!
Follow our instructions and use the recommended
file gauge. A damaged or badly sharpened chain
increases the risk of accidents.
Maintain the correct depth gauge setting! Follow our
instructions and use the recommended depth gauge
clearance. Too large a clearance increases the risk
of kickback.
10
308 - 004 - 27.09.2017
Keep the chain properly tensioned! If the chain is
slack it is more likely to jump off and lead to
increased wear on the bar, chain and drive sprocket.
Keep cutting equipment well lubricated and properly
maintained! A poorly lubricated chain is more likely
to break and lead to increased wear on the bar,
chain and drive sprocket.
Some terms that describe the bar and chain
To maintain the safety features of the cutting equipment,
you should replace a worn or damaged bar or chain with
a guide bar and saw chain combinations recommended
by Zenoah. See instructions under the heading
Accessories on page 34
for a list of replacement bar
and chain combinations we recommend.

Fuel
This product have a two-stroke engine and must always
run on a mixture of gasoline and two-stroke oil.
Gasoline
Use unleaded or leaded gasoline of a good quality.
The lowest recommended octane grade is 90 (RON).
There is a risk that use of lower grade causes
knocking. This gives rise to a high engine
temperature and increased bearing load, which
results in serious engine damages.
We recommend a higher octane when you do work
with continuous high revs, for example when you use
the limbing technique.
Ethanol fuel
Zenoah recommends commercial available fuel with
maximum 10% ethanol contents.
Running-in
Do not run the engine at unloaded full throttle for
extended periods during the first 10 hours.
Two-stroke oil
For best results and performance use Zenoah two-
stroke oil, which is specially formulated for our two-
stroke engines. Mixture 1:50 (2%).
If Zenoah two-stroke oil is not available, use a
different two-stroke oil of good quality that is
formulated for air-cooled engines. Consult your
servicing dealer when you select an oil.
Do not use two-stroke oil for water-cooled outboard
engines, also referred to as outboard oil.
Do not use oil intended for four-stroke engines.

To mix gasoline and two-stroke oil
CAUTION: There is a risk that small errors
influence the ratio of the mixture drastically
when you mix small quantities of fuel.
Carefully measure the quantity of oil to be
mixed to make sure that you get the correct
mixture.
1. Fill half the quantity of the gasoline to be used.
2. Add the full quantity of oil and mix (shake) the fuel
mixture.
3. Add the remaining quantity of gasoline.
4. Carefully mix (shake) the fuel mixture and fill the fuel
tank of the product.
5. Empty and clean the fuel tank if you do not use the
product for some time.
Note: Do not mix fuel for more than 1 month at a time
and always mix gasoline and oil in a clean container
intended for fuel.
Chain oil
All Zenoah chainsaws have an automatic chain
lubrication system. On some models the oil flow is also
adjustable.
Chain oil must show good adherence to the saw chain
and also keep its flow characteristics during warm
summer and cold winter weather.
14
308 - 004 - 27.09.2017
The chain oil from Zenoah has a vegetable oil base and
is also biodegradable. We recommend you to use of our
chain oil for maximum saw chain life and to minimise
environmental damage. If this chain oil is not available,
we recommend you to use a standard chain oil.
The fuel runs out before the chain oil from the two tanks.
This is a safety feature and it is necessary that you
follow the requirements below:
Use an oil of the right grade (suitable viscosity
range) to agree with the air temperature. If the oil is
too thin it will run out before the fuel. In temperatures
below 0°C (32°F) some oils become too viscous.
This can cause the oil pump to overload and result in
damage to the oil pump components.
Adjust the carburetor as recommended. A lean
mixture causes the chain oil tank to empty before the
fuel tank.
Use the recommended cutting equipment. A guide
bar that is too long will use more chain oil.
WARNING: Do not use waste oil! Waste oil
is dangerous to you and the environment.
Waste oil also causes damage to the oil
pump, the guide bar and the saw chain.
WARNING: Deficiente lubrication of the
cutting equipment can cause the saw chain
to break, which can cause serious injury or
death.
Consult your servicing dealer when you select a chain
oil.
To fill the fuel tank
1. Clean the area around the fuel tank cap.
2. Shake the container and make sure that the fuel is

General information about working
technique
Below we provide some general advice when you use
this product.
WARNING: The information related to
working technique in this operator's manual
is not considered proper training to operate
this tree-service product. This product must
be used by trained tree-service operators
only! Use without proper training can result
in severe injuries. Do not attempt any task
that you feel unsure of!
To cut from above = To cut on the pull stroke. This
means that the saw chain pulls through the tree and
that the chainsaw body lies on the trunk when you
cut. To cut on the pull stroke gives the operator
better control of the chainsaw and the position of the
kickback zone.
To cut from below = To cut on the push stroke. This
means that the saw chain tries to push the chainsaw
against the operator.
WARNING:
Be careful when you cut with
the top edge of the guide bar. If the saw
chain gets caught in the trunk, the
chainsaw can be pushed against you.
Unless you prevent this force there is a
risk that the only the kickback zone of
the guide bar touches the tree, which will
lead to a kickback.
308 - 004 - 27.09.2017 17
Always use full throttle when you cut.
Reduce the speed to idle after every cut.
CAUTION: If you run the engine for too
long at full throttle and without any load,
for example without resistance from the
saw chain when you cut, this can lead to
serious engine damage.
Set the spiked bumper (if one is fitted) into the trunk
and use it as a lever then you apply cutting feed
force.
What is kickback?
WARNING:
Kickback can happen very
suddenly and violently; kicking the
chainsaw, guide bar and saw chain back at
the user. If this happens when the saw chain
is moving it can cause very serious, even
fatal injuries. It is vital you understand what
causes kickback and that you can avoid it by
taking care and using the correct working
technique. By being prepared you reduce
the risk.
The word kickback is used to describe the sudden
reaction that causes the chainsaw and guide bar to jump
off an object when the upper quadrant of the tip of the
bar, known as the kickback zone, touches an object.
Kickback always occurs in the cutting plane of the guide
bar. Normally the chainsaw and guide bar are thrown
backwards and upwards towards the user. However, the
chainsaw may move in a different direction depending
on the way it was being used when the kickback zone of
the guide bar touched the object.
Kickback only occurs if the kickback zone of the guide
bar touches an object.
To prepare the product for use in the
tree
1. Do a check of, fuel, start and warm up the product.
This should be done by the ground worker.
2. Engage the chain brake.
3. During tree maintenance work above ground level
the product must be secured. Fit the product with a
suitable strop as an attachment to the operator's
harness.
a) Attach one end of the strop around the rope
eyelet on the rear of the product.
Note:
The strop is a fail safe where if the
operator loses control of the product, the strop
will prevent the product from falling to the
ground. The recommended primary securing
method is the belt eyelet to be attached to the
sequiring hook on the operator's harness.
However, if the strop is used as a primary
securing method, the product must be lowered to
the full extent of the safety line and not dropped
from working height to the end of the safety rope.
18 308 - 004 - 27.09.2017
b) Provide suitable karabiners to allow indirect (via
the strop) and direct (at the attachment point on
the product) attachment of the product to the
operator's harness.
CAUTION: The belt eyelet is not
dimensioned for use with a so-called
safety rope. Use the rope eyelet for
this purpose.
c) Send the product up to the operator in the tree
and attach the other end of the strop to the
operator's harness.
WARNING: Make sure that the
product is securely attached when
you send it up to the operator in the
tree.
d) Make sure that the product is secured to the
harness before you disconnect from the means
of ascent. This should be done by the operator in
the tree.
4. The product should only be attached to the
recommended attachment points on the harness.
There are four attachment points which are mid-point
front and rear and on the sides.
Note: If you attach the product to the centre rear
mid-point you will keep the product clear from
climbing lines and support its weight centrally down
your spine.
WARNING: Make sure that the product
is secured in the new position when you
move it from any attachment point to
another, before you release it from the
previous attachment point.
To use the product in the tree
Aim for a secure work position when you use the
product when you cut horizontal sections at hip level
and when you cut vertical sections at solar plexus
level. This allows you to hold the product with both
hands and should be considered as a general rule.
Where you work close into vertical stems with a low
lateral forces on your work position a good footing
may be all that you need to maintain a secure work
position. However, as you move away from the stem
you will need to take steps to remove or counteract
the increasing lateral forces. This can be done if you
redirect the main line via a supplementary anchor
point or if you use a adjustable strop directly from the
harness to a supplementary anchor point.
To gain a good footing at the work position can be
assisted if you use a temporary foot stirrup that is
created from an endless sling.
WARNING: An analysis of accidents with
these products during tree service
operations shows primary cause as being
inappropriate one-handed use of the
product. In the vast majority of accidents,
operators fail to adopt a secure work
position which allows them to hold both
handles of the product. This results in
increased risk of injury due to:
that the operator doesn't have a firm grip
on the product in an event of a kickback.
a lack of control of the product such that
it is more liable to contact climbing lines
and the operator's body (particularly the
left hand and arm).
308 - 004 - 27.09.2017 19
that the operator looses control from
insecure work position that results in
contact with the product. One example is
unexpected movement during operation
of the product.
To free a trapped product
Do the following if the product becomes trapped when
you cut in the tree:
1. Switch off the product.
2. Attach the product securely to the tree inboard (in
example towards the truck side) of the cut or to at
separate tool line.
3. Pull the product from the kerf and lift the branch as
much as you need to at the same time.
4. Use a handsaw or a second chainsaw to release the
trapped product if necessary. Cut a minimum of 30
cm away from the trapped product.
Note: Don't try to pull the product free. If you do you may
be injured by the saw chain then the product suddenly
breaks free. Use a lever to open up the cut and free the
product. Wheather a handsaw or a second chainsaw is
used to free a stuck product, the release cuts should
always be outboard (toward the tips of the branch) in
order to prevent the product from being taken with the
section and further complicating the situation.
Maintenance
Introduction
WARNING: Read and understand the safety
chapter before you carry out any
maintenance work on the product.
WARNING: Always wear approved
protective gloves and protective goggles or
a visor.
Note: The user must only carry out the maintenance and
service work described in this Operator's Manual. More
extensive work must be carried out by a servicing
dealer.
Carburettor adjustment
Due to existing environmental and emissions legislation
your chain saw is equipped with movement limiters on
the carburetor adjuster screws. These limit the
adjustment possibilities to a maximum of a 1/2 turn.

Your Zenoah product has been designed and
manufactured to specifications that reduce harmful
exhaust fumes.
Function
The carburetor governs the speed of the engine via
the throttle trigger. Air and fuel are mixed in the
carburetor. The air/fuel mixture is adjustable. Correct
adjustment is essential to get the best performance
from the product.
The setting of the carburetor means that the engine
is adapted to local conditions, for example the
climate, altitude, fuel and the type of 2-stroke oil.
The carburetor has three adjustment controls: L (low
jet speed), H (high jet speed) and T (idle adjustment
screw).
T
L
H
The L- and H-jets are used to adjust the supply of
fuel to match the rate that air is admitted, which is
controlled with the throttle. If they are screwed
clockwise the air/fuel ratio becomes leaner (less fuel)
and if they are turned anti-clockwise the ratio
becomes richer (more fuel). A lean mixture gives a
higher engine speed and a rich mixture gives a lower
engine speed.
The T-screw regulates the throttle setting at idle
speed. If the T-screw is turned clockwise this gives a
higher idle speed; turning it anti-clockwise gives a
lower idle speed.
Basic settings and running in
The basic carburetor settings are adjusted during testing
at the factory.
