FUEL HANDLING
10 – English
Fuel safety
Never start the machine:
1 If you have spilled fuel on it. Wipe off the spillage and
allow remaining fuel to evaporate.
2 If you have spilled fuel on yourself or your clothes,
change your clothes.Wash any part of your body that
has come in contact with fuel. Use soap and water.
3 If the machine is leaking fuel. Check regularly for
leaks from the fuel cap and fuel lines.
Transport and storage
•Store and transport the machine and fuel so that there
is no risk of any leakage or fumes coming into contact
with sparks or open flames, for example, from
electrical machinery, electric motors, electrical relays/
switches or boilers.
• When storing and transporting fuel always use
approved containers intended for this purpose.
• When storing the machine for long periods the fuel
tank must be emptied. Contact your local petrol
station to find out where to dispose of excess fuel.
Drain off the fuel in an approved container outdoors
and well clear of naked flames.
• Ensure the machine is cleaned and that a complete
service is carried out before long-term storage.
• The transport guard must always be fitted to the
cutting attachment when the machine is being
transported or in storage.
• Secure the machine during transport.
• In order to prevent unintentional starting of the engine,
the spark plug cap must always be removed during
long-term storage, if the machine is not under close
supervision and when performing all service
measures.
Fuel
CAUTION! The machine is equipped with a two-stroke
engine and must always be run using a mixture of petrol
and two-stroke oil. It is important to accurately measure
the amount of oil to be mixed to ensure that the correct
mixture is obtained. When mixing small amounts of fuel,
even small inaccuracies can drastically affect the ratio of
the mixture.
Petrol
CAUTION! Always use a quality petrol/oil mixture at least
90 octane (RON). If your machine is equipped with a
catalytic converter (see chapter on Technical data) always
use a good quality unleaded petrol/oil mixture. Leaded
petrol will destroy the catalytic converter.
Use low-emission petrol, also known as alkylate petrol, if
it is available.
• The lowest octane recommended is 90 (RON). If you
run the engine on a lower octane grade than 90 so-
called knocking can occur. This gives rise to a high
engine temperature, which can result in serious
engine damage.
• When working at continuous high revs a higher octane
rating is recommended.
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, you may use
another two-stroke oil of good quality that is intended
for air cooled engines. Contact your dealer when
selecting an oil.
• Never use two-stroke oil intended for water-cooled
outboard engines, sometimes referred to as outboard
oil.
• Never use oil intended for four-stroke engines.
• A poor oil quality and/or too high oil/fuel ratio may
jeopardise function and decrease the life time of
catalytic converters.
• Mixing ratio
!
WARNING!Take care when handling fuel.
Bear in mind the risk of fire, explosion
and inhaling fumes.
!
WARNING! Fuel and fuel fumes 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.

Mixing
•Always mix the petrol and oil in a clean container
intended for fuel.
• Always start by filling half the amount of the petrol to
be used. Then add the entire amount of oil. Mix
(shake) the fuel mixture.Add the remaining amount of
petrol.
• Mix (shake) the fuel mixture thoroughly before filling
the machine’s fuel tank.
• Do not mix more than one month’s supply of fuel at a
time.
• If the machine is not used for some time the fuel tank
should be emptied and cleaned.
Fueling
•Always use a fuel container with an anti-spill valve.
• Clean the area around the fuel cap. Contamination in
the tank can cause operating problems.
• Ensure that the fuel is well mixed by shaking the
container before filling the tank.
!
WARNING! The catalytic converter
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.

Carburettor
Your ZENOAH product has been designed and
manufactured to specifications that reduce harmful
emissions.
Function
•The carburettor governs the engine’s speed via the
throttle control. Air and fuel are mixed in the
carburettor. The air/fuel mixture is adjustable. Correct
adjustment is essential to get the best performance
from the machine.
• Adjusting the carburettor means that the engine is
adapted to local operating conditions, e.g. climate,
altitude, petrol and the type of 2-stroke oil.
Adjusting the idle 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.
Before any adjustments are made, make sure that the air
filter is clean and the air filter cover is fitted.
Adjust the idle speed with the idle adjustment screw T, if
adjustment is necessary. First turn the idle adjustment
screw T clockwise until the blades start to move.Then
turn the idle adjustment screw T anticlockwise until the
blades stop.The idle speed is correctly adjusted when the
engine runs smoothly in every position.There should also
be a clear margin to the speed at which the blades start
to move. Rec. idle speed: See the Technical data section.
The blades must also remain stationary when the choke
control is in the start throttle position.
Muffler
CAUTION! Some mufflers are fitted with a catalytic
converter. See chapter on Technical data to see whether
your machine is fitted with a catalytic converter.
The muffler is designed to reduce the noise level and to
direct the exhaust gases away from the operator. The
exhaust gases are hot and can contain sparks, which may
cause fire if directed against dry and combustible
material.
Some mufflers are equipped with a special spark arrestor
mesh. If your machine has this type of muffler, you should
clean the mesh at least once a week. This is best done
with a wire brush.
On mufflers without a catalytic converter the mesh should
be cleaned weekly, or replaced if necessary. On mufflers
fitted with a catalytic converter the mesh should be
checked, and if necessary cleaned, monthly. If the mesh
is damaged it should be replaced. If the mesh is
frequently blocked, this can be a sign that the
performance of the catalytic converter is impaired.
!
WARNING! The complete clutch cover
and gear housing must be fitted before
the machine is started, otherwise the
clutch may come loose and cause
personal injury.
!
WARNING! If the idle speed cannot be
adjusted so that the cutting attachment
stops, contact your dealer/service
workshop. Do not use the machine until
it has been correctly adjusted or

MAINTENANCE
English – 17
Contact your dealer to inspect the muffler. A blocked
mesh will cause the machine to overheat and result in
damage to the cylinder and piston.
CAUTION! Never use a machine with a defective muffler.
Cooling system
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The cooling system consists of:
1 Fins on the flywheel.
2 Cooling fins on the cylinder.
3 Cylinder cover (directs cold air over the cylinder).
Clean the cooling system with a brush once a week, more
often in demanding conditions. A dirty or blocked cooling
system results in the machine overheating which causes
damage to the piston and cylinder.
Spark plug
The spark plug condition is influenced by:
• Incorrect carburettor adjustment.
• An incorrect fuel mixture (too much or incorrect type
of oil).
• A dirty air filter.
These factors cause deposits on the spark plug
electrodes, which may result in operating problems and
starting difficulties.
If the machine is low on power, difficult to start or runs
poorly at idle speed: always check the spark plug first
before taking any further action. If the spark plug is dirty,
clean it and check that the electrode gap is 0,9-1,0 mm.
The spark plug should be replaced after about a month in
operation or earlier if necessary.
CAUTION! Always use the recommended spark plug
type! Use of the wrong spark plug can damage the piston/
cylinder. Check that the spark plug is fitted with a
suppressor.
Air filter
The air filter must be regularly cleaned to remove dust
and dirt in order to avoid:
• Carburettor malfunctions.
• Starting problems.
• Loss of engine power.
• Unnecessary wear to engine parts.
• Excessive fuel consumption.
Clean the filter every 25 hours, or more regularly if
conditions are exceptionally dusty.
Cleaning the air filter
Remove the air filter cover and take out the filter. Wash it
clean in warm, soapy water. Ensure that the filter is dry
before refitting it.
An air filter that has been in use for a long time cannot be
cleaned completely. The filter must therefore be replaced
with a new one at regular intervals. A damaged air filter
must always be replaced.
Fuel filter
When the engine runs short of fuel supply, check the fuel
cap and the fuel filter for blockage.
!
WARNING! Mufflers fitted with catalytic
converters get very hot during use and
remain so for some time after stopping.
This also applies at idle speed. Contact
can result in burns to the skin.
Remember the risk of fire!

Gear
There is a grease nipple on the gearbox. Use a grease
gun to top up with grease.This should be carried out after
approximately every 50 working hours. Use Zenoah
special grease.
Pump in grease until clean grease emerges to the blades.
Cleaning and lubrication
Clean any resin and plant residue from the blades using
cleaning agent before and after using the machine.
Lubricate the blade bars with special grease before long
periods of storage.
