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.
WARNING! Always ensure there is adequate
!
ventilation when handling fuel.
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
JONSERED recommends the use of alkylate fuel or
environment 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 performance use JONSERED 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.

Mixing
•
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.
•
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.
