Fuel

NOTE!
The machine is fitted with a two-stroke engine and must
always be run on a mixture of petrol and two-stroke oil. It is
important to measure the quantity of oil accurately, to ensure
the correct mixture ratio. Small discrepancies in the amount of
oil have a great bearing on the proportions of the fuel mixture
when mixing small amounts of fuel.
!
WARNING!
Always provide good ventilation when
handling fuel.
Petrol
NOTE!
Always use an oil-mixed
quality petrol (at least 90
octane). If your machine is
equipped with a catalytic
converter, (see "technical
data") an unleaded, oil
mixed quality petrol should
always be used. A leaded
petrol will destroy the
catalytic converter.
• 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 produced for
clearing saws and chain
saws.
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 of four-stroke engines.

FUEL HANDLING

Mixture

• Always mix petrol and oil in a clean container intended for
petrol.
• Always start by filling 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 filling in the
machine's fuel tank.
• Do not mix more than max. one month's supply of fuel.
• If the machine is not used for a long period of time, the fuel
tank should be emptied and cleaned.

Fuelling

!
• Clean around the fuel
cap. Contamination in
the tank can disrupt
operations.
• 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 handling the saw near
flammable substances or vapours.
WARNING!
The following precautions reduce the risk
of fire:
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 place before
starting.
