FUEL HANDLING
Fuel mixture
NOTE!
The machine is fitted with a two-stroke engine and must
always be run on a mixture of petrol and two-stroke oil. It is
important to measure the quantity of oil accurately, to ensure
the correct mixture ratio. Small discrepancies in the amount of
oil have a great bearing on the proportions of the fuel mixture
when mixing small amounts of fuel.
Gasoline
NOTE!
Always use high grade
unleaded oil mixed
gasoline (minimum 87
RON). Leaded fuel will
destroy the catalytic
converter and it will no
longer serve its purpose.
• This engine is certified to
operate on unleaded
gasoline.
• The lowest
recommended octane
rating is 87. If you run
the engine on lower
octane rating than 87 so-
called “knocking“ can
occur. This leads to an
increased engine
temperature, which can
result in a serious engine
breakdown.
• When working at
continuous high revs a
higher octane rating is
recommended.
WARNING!
Always provide good ventilation when
handling fuel.
!
• Clean around the fuel
cap. Contamination in
the tank can disrupt
operations.
• Ensure that the fuel is
well mixed by shaking the
container before filling
the tank.
!
WARNING!
The catalytic converter muffler gets very hot
during and after use. This also applies
during idling. Be aware of the fire hazard,
especially when handling the saw near
flammable substances or vapours.
Fuelling
WARNING!
The following precautions reduce the risk of
fire:
Do not smoke or place any sources of heat
in the vicinity of the fuel. Never refuel when
the engine is running. Always stop the
engine and let it cool for a few minutes
before refuelling. Open the fuel cap slowly
when fuelling so that any over pressure is
released slowly. Tighten the fuel cap
carefully after refuelling. Always move the
machine from the fuelling place before
starting.

Two-stroke oil
• For the best results use JONSERED two-stroke oil, which
has been specially produced for clearing saws and chain saws.
Mixing ratio 1:50 (2%).
• Never use two-stroke oil intended for water cooled outboard
motors, so-called outboard motor oil.
• Never use oil intended of four-stroke engines.
Min. 3 m
(10 ft)
Mixture
• Always mix gasoline and oil in a clean container intended for
fuel.
• Always start by filling half the quantity of gasoline required.
Then add the entire oil quantity. Mix (shake) the fuel
mixture. Fill the remaining quantity of gasoline.
• Mix (shake) the fuel mixture carefully before filling in the
machine‘s fuel tank.
• Do not mix more than max. one month’s supply of fuel.
• If the machine is not used for a long period of time, the fuel
tank should be emptied and cleaned.
• This engine is certified to operate on unleaded gasoline.
