Fuel mixture
NOTE!
The edger is fi tted with two-stroke engines and must always
be run on a mixture of petrol and two-stroke oil. To ensure
the correct mixture proportions it is important to measure the
quantity of oil accurately. When mixing small amounts of fuel
small discrepancies in the amount of oil have a great bearing on
the proportions of the fuel mixture.
FUEL HANDLING
Petrol
• Always use unleaded, oil
mixed, quality petrol! (at least
90 octane). Leaded petrol
will destroy the catalytic
converter and it will no longer
serve its purpose.
• The lowest recommended
octane rating is 90. If you
run the engine on a petrol
with a lower octane rating
than 90 so-called “knocking”
can occur. This leads
to an increased engine
temperature, which can
result in a serious engine
breakdown.
• When working at continuous
high revs a higher octane
rating is recommended.
Two-stroke oil
• For the best results use
HUSQVARNA two stroke oil,
which has been specially
developed for 2-stroke
engines. Mixing ratio 1:50
(2%).
• If HUSQVARNA two stroke
oil is not available you can
use a high quality two-stroke
oil intended for air cooled
engines. Contact your dealer
when selecting an oil. Mixing
ratio: 1:33 (3%).
• Never use two-stroke oil
intended for water cooled
outboard motors, so-called
outboard motor oil.
• Never use oil intended for
four-stroke engines.
Mixture
• Always mix petrol and oil in a clean container intended for
petrol.
• Always start by fi lling half the quantity of petrol required. Then
add the entire oil quantity. Mix (shake) the fuel mixture. Fill the
remaining quantity of petrol.
• Mix (shake) the fuel mixture carefully before fi lling in the
machineʼs fuel tank.
• Do not mix fuel for more than max. one month's supply of fuel.
• If the edger is not used for a long period of time, the fuel tank
should be emptied and cleaned.
Fuelling
!
WARNING!
The following precautions reduce the risk of
fi re:
Do not smoke or place any sources of heat in
the vicinity of the fuel.
Never refuel when the engine is running.
Always stop the engine and let it cool for a
few minutes before refuelling.
Open the fuel cap slowly when fuelling so that
any over pressure is released slowly.
Tighten the fuel cap carefully after refuelling.
Always move the machine from the fuelling
area before starting.
• Clean around the fuel cap.
Contamination in the tank can
disrupt operations.
• Ensure that the fuel is
well mixed by shaking the
container before fi lling the
tank.
!
WARNING!
The catalytic converter muffl er becomes very
hot during and after use. This also applies
during idling. Be aware of the fi re hazard,
especially when handling the saw near
fl ammable substances or vapours.
WARNING!
Always provide good ventilation when
handling fuel.
