Fuel mixture

NOTE!
The machine is fitted with a two-stroke engine and must
always be run on a mixture of gasoline 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.
Gasoline
NOTE!
Always use an oil-mixed
quality gasoline (at least 87
octane). If your machine is
equipped with a catalytic
converter, (see "technical
data") an unleaded, oil
mixed quality gasoline
should always be used. A
leaded gasoline will destroy
the catalytic converter.
• This engine is certified to
operate on unleaded
gasoline.
• The lowest recommended
octane rating is 87. If you
run the engine on lower
octane rating than 87 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
clearing saws and chain
saws. Mixing ratio 1:50 (2%).
• 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 gasoline and oil in a clean container intended for
fuel.
• Always start by filling half the quantity of gasoline required.
Then add the entire oil quantity. Mix (shake) the fuel
mixture. Fill the remaining quantity of gasoline.
• 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.
• This engine is certified to operate on unleaded gasoline.

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.
