7. FUEL MIXTURE

NOTE! The machine is tted 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.
WARNING! Always provide good ventilation when han
dling fuel.
Petrol
NOTE!
• Always use an oil-mixed quality petrol (at least 90
octane).
• Recommended octane rating is 90. If you run the
engine on a petrol 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 high level two-stroke oil.
Mixing ratio 1:25 (4%).
• Never use oil intended of four-stroke engines.
