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.
•
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.
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 ratio
1:50 (2%) for all 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 32°F (0°C) 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.
Fueling
WARNING! Taking the following
!
precautions, will lessen the risk of fire:
Do not smoke and do not place any hot
objects in the vicinity of fuel.
Always stop the engine and let it cool
for a few minutes before refuelling.
When refuelling, open the fuel cap
slowly so that any excess pressure is
released gently.
Tighten the fuel cap carefully after
refuelling.
Always move the machine away from
the refuelling area before starting.
Clean the area around the fuel cap. Clean the fuel and
chain oil tanks regularly. The fuel filter must be replaced
at least once a year. Contamination in the tanks causes
malfunction. Make sure the fuel is well mixed by shaking
the container before refuelling. The capacities of the
chain oil tank and fuel tank are carefully matched. You
should therefore always fill the chain oil tank and fuel
tank at the same time.
WARNING! Fuel and fuel vapor are
!
highly flammable. Take care when
handling fuel and chain oil. Be aware of
the risks of fire, explosion and those
associated with inhalation.
Fuel safety
•
Never refuel the machine while the engine is running.
•
Make sure there is plenty of ventilation when
refuelling or mixing fuel (gasoline and 2-stroke oil).
•
Move the machine at least 10 ft (3 m) from the
refuelling point before starting it.
•
Never start the machine:
1
If you have spilled fuel or chain oil on the machine. Wipe
off the spillage and allow remaining fuel to evaporate.
2
If you have spilled fuel on yourself or your clothes,
change your clothes. Wash any part of your body that
has come in contact with fuel. Use soap and water.
