Fuel mixture

NOTE!
The edger is fi tted with two-stroke engines and must always
be run on a mixture of gasoline 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 has a great bearing on
the proportions of the fuel mixture.
!
WARNING!
Always provide good ventilation when han-
dling fuel.
Gasoline
NOTE!
Always use high grade
unleaded oil mixed gasoline
(minimum 87 RON). Leaded
fuel will destroy the catalytic
converter and it will no longer
serve its purpose.
• This engine is certifi ed to
operate on unleaded gaso-
line.
• 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 break-
down.
• When working at continuous
high revs a higher octane rat-
ing is recommended.
Two-stroke oil
• For the best results use
HUSQVARNA two-stroke
oil, which has been specially
developed for two-stroke
engines.
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.

Fuelling

!
• Clean around the fuel
cap. Contamination in the
tank can disrupt opera-
tions.
• Ensure that the fuel is
well mixed by shaking the
container before fi lling the
tank.
WARNING!
The catalytic converter muffl er gets 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 sub-
stances or vapours.
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 place
before starting.
