FUELING ENGINE
WARNING:
Remove fuel cap slowly
when refueling.
This engine is certified to operate on unleaded
petrol. Before operation, petrol must be mixed
with a good quality 2- -cycle air- -cooled engine oil
designed to be mixed at a ratio of 40:1. A 40:1
ratio is obtained by mixing 5 liters of unleaded
petrol with 0,125 liter of oil. DO NOT USE auto-
motive oil or marine oil. These oils will cause en-
gine damage. When mixing fuel, follow instruc-
tions printed on oil container. Once oil is added
to petrol, shake container momentarily to assure
that the fuel is thoroughly mixed. Always read
and follow the safety rules relating to fuel before
fueling your unit.
CAUTION:
Never use straight petrol in your
unit. This will cause permanent engine damage.

FUEL REQUIREMENTS

Use good quality unleaded petrol. The lowest
recommended octane grade is 90 (RON).
IMPORTANT
Use of alcohol blended fuels (more than 10% al-
cohol) can cause major engine performance
and durability problems.
WARNING:
Incorrect use of fuel and/
or lubricants will cause problems such as:
improper clutch engagements, overheat-
ing, vapor lock, power loss, lubrication defi-
ciency, deterioration of fuel lines, gaskets
and internal carburetor components, etc.
Alcohol blended fuels will cause a high ab-
sorption of moisture in the fuel/oil mixture,
causing the separation of oil and fuel.
