FUEL HANDLING
Fuel
Note! The
machine
is equipped
with a two-stroke
engine
and must always
be run using
a mixture
of gasoline
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.
Gasoline
Use good quality unleaded gasoline.
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 87
((RON+MON)/2).
If you run the engine on a lower
octane grade than 87 so-called knocking can occur.
This gives rise to a high engine temperature and
increased bearing load, which can result in serious
engine damage.
When working with continuous high revs (e.g. limbing)
a higher octane is recommended.
Environment fuel
HUSQVARNA recommends the use of alkylate fuel or
environmental
fuel for four-stroke engines blended with
two-stroke oil as set out below. Note that carburetor
adjustment may be necessary when changing the type of
fuel (see instructions under the heading Carburetor).
Running=in
Avoid running at a too high speed for extended periods
during the first 10 hours.
Two-stroke oil
For best results and pedormance use HUSQVARNA
two-stroke engine oil, which is specially formulated for
our air-cooled two stroke-engines.
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.

(2%) for all engines.

Always mix the gasoline and oil in a clean container
intended for fuel.
Always start by filling half the amount of the gasoline
to be used.Then
add the entire amount of oil. Mix
(shake) the fuel mixture. Add the remaining amount of
gasoline.
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.
Chain oil
We recommend the use of special oil (chain oil) with
good adhesion characteristics. (48)
Never use waste oil. This results in damage to the oil
pump, the bar and the chain.
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.
Contact your service agent when choosing chain oil.
