In order to prevent unintentional starting of the engine, the spark plug cap must always be
removed during long-term storage, if the machine is not under close supervision and when
performing all service measures.
Take care when handling fuel. Bear in mind the risk of fire, explosion and
inhaling fumes.
9.2.3
Fuel
The machine is equipped with a two-stroke engine and must always been run using a mixture
of petrol 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.
Fuel and fuel fumes are highly inflammable and can cause serious injury
when inhaled or allowed to come in contact with the skin. For this reason
observe caution when handling fuel and make sure there is adequate
ventilation.
9.2.4
Petrol
Always use a quality petrol/oil mixture at least 90 octane (RON).
Use low-emission petrol, also known as alkylate petrol, if it is available.
The lowest octane recommended is 90 (RON). If you run the engine on a lower octane grade
than 90 so- called knocking can occur. This gives rise to a high engine temperature, which can
result in serious engine damage.
When working at continuous high revs a higher octane rating is recommended.
9.2.5
Two-stroke oil
For best results and performance use 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.
A poor oil quality and/or too high oil/fuel ratio may jeopardize function and decrease the life
time of catalytic converters.
9.2.6
Mixing
Always mix the petrol and oil in a clean container intended for fuel.
Always start by filling half the amount of the petrol to be used. Then add the entire amount
of oil. Mix (shake) the fuel mixture. Add the remaining amount of petrol.
Mix (shake) the fuel mixture thoroughly before filling the machine’s fuel tank.
