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.
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 90. If you
run the engine on a
gasoline with a lower
octane rating than 90 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.
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.

NOTE!
The machine is fitted with a two-stroke engine and must
always be run on a mixture of gasoline 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.
Mixture
• Always mix gasoline and oil in a clean container intended
for gasoline.
• 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 clearing saw 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.

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.
• 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.
