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.
11.2.5 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.
11.2.6 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.
 Do not mix more than one month’s supply of fuel at a time.
 If the machine is not used for some time the fuel tank should be emptied and cleaned.
11.2.7 Fuelling
Taking the following precautions, will lessen the risk of fire:
 Do not smoke or place hot objects near fuel.
 Always shut off the engine before refueling.
 Always stop the engine and let it cool for a few minutes before refueling.
 When refueling, open the fuel cap slowly so that any excess pressure is released gently.
 Tighten the fuel cap carefully after refueling.
 Always move the machine away from the refueling area before starting.
 Always use a fuel container with an anti-spill valve.
 Clean the area around the fuel cap. Contamination in the tank can cause operating
problems.
 Ensure that the fuel is well mixed by shaking the container before filling the tank.
11.3 Using the machine
11.3.1 Check and starting
 Never use the machine without a guard nor with a defective guard.
 All covers must be correctly fitted and undamaged before you start the machine.
