FUEL HANDLING
Fuel
Two-stroke oil
•
For best results and performance use HUSQVARNA
two-stroke engine oil, which is specially formulated for
our air-cooled two-stroke engines.
Note! 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.
•
Never use two-stroke oil intended for water-cooled
engines, sometimes referred to as outboard oil (rated
TCW).
•
•
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.
WARNING! Always ensure there is
!
adequate ventilation when handling fuel.

Use good quality unleaded or leaded petrol.

CAUTION! Engines equipped with catalytic
converters must be run on unleaded fuel
mixtures. Leaded gasoline will destroy the catalytic
converter and it will no longer serve its purpose. The
green fuel cap on saws fitted with catalytic converters
means that only unleaded gasoline can be used.

The lowest recommended octane grade 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 and increased bearing load,
which can result in serious engine damage.
Mixing
When working with continuous high revs (e.g.limbing)
a higher octane is recommended.
Environment fuel
HUSQVARNA recommends the use of alkylate fuel,
either Aspen two-stroke fuel or environmental fuel for
four-stroke engines blended with two-stroke oil as set out
below. Note that carburettor adjustment may be
necessary when changing the type of fuel (see the
instructions under the heading Carburettor).
•
•
Always mix the petrol and oil in a clean container
intended for fuel.
Running-in
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.
Avoid running at a too high speed for extended periods
during the first 10 hours.
•
•
•
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.
