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.

Petrol
Mixing
•
•
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.
•
•
Always mix the petrol and oil in a clean container
intended for fuel.
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.
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.
•
•
•
Mix (shake) the fuel mixture thoroughly before filling
the machine’s fuel tank.
•
When working with continuous high revs (e.g.limbing)
a higher octane is recommended.
Do not mix more than one month’s supply of fuel at a
time.
Environment fuel
If the machine is not used for some time the fuel tank
should be emptied and cleaned.
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).
Chain oil
•
We recommend the use of special oil (chain oil) with
good adhesion characteristics.
Running-in
Avoid running at a too high speed for extended periods
during the first 10 hours.
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.
•
•
•
Never use waste oil. This results in damage to the oil
pump, the bar and the chain.
Never use two-stroke oil intended for water-cooled
engines, sometimes referred to as outboard oil (rated
TCW).
It is important to use oil of the right grade (suitable
viscosity range) to suit the air temperature.
In temperatures below 0°C (32°F) some oils become
too viscous.This can overload the oil pump and result
in damage to the oil pump components.
•
•
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.
•
Contact your service agent when choosing chain oil.
