Fuel
Petrol
- Use good quality unleaded or leaded petrol.
- The lowest octane recommended is 90 (RON). If you run the engine on a lower octane grade than
90 socalled 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.
Environment fuel
We recommends the use of alkylate fuel, either Aspen two-stroke fuel or environmental fuel for
four-stroke engines blended with two-stroke oil as set out below. Note that carburettor adjustment
may be necessary when changing the type of fuel (see the instructions under the heading Carburet-
tor).
Ethanol blended fuel, E10 may be used (max 10% ethanol blend). Using ethanol blends higher than
E10 will create lean running condition which can cause engine damage.
Two-stroke oil
- For best results and performance use twostroke 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.
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.
NOTICE! The machine is equipped with a two-stroke engine and must always be 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.
