FUEL
Fig.15 -2 STROKE - WARNING: : The brushcutter is equipped with a 2-stroke
engine, therefore only fuel mixed with special oil for 2-stroke engines
should be used. Only prepare the mixture required for use. Do not smoke
and always refuel with the engine switched off and away from flames. Use
fuel with an octane rating of not less than 90. Only mix petrol with 2-stroke
oil. Use ACTIVE 2-stroke oil, which has been specially developed for best
results, in a ratio of 1:50 (2%). If ACTIVE oil is not available, use another
synthetic 2-stroke oil at a ratio of 1:50 (2%) or mineral oil at a ratio of 1:25
(4%).
Important: Stir the canister vigorously and for a long time, this should
be carefully repeated each time fuel is taken from the canister. The
characteristics of the mixture are subject to ageing and therefore alter over
time. Do not use a mixture that has been prepared for several weeks, as
this could result in engine damage. Fill the fuel tank only 3/4 full to allow the
mixture to expand.
