2.5. Mixing two stroke oil.
Fill the mixing bottle with fresh unleaded petrol to the fuel level line. You MUST only use fresh unleaded
fuel and 2 stroke engine oil mixture. For the first time ONLY a mixing ratio of 25:1 should be used to
lubricate all engine parts to an optimum level. Thereafter the mix is 40:1.
2.6. Adding fuel.
Unscrew the fuel tank cap and carefully add the fuel/2 stroke mixture as in section 2.5. DO NOT overfill
and allow a 25mm gap at the top of the tank. Once full replace and correctly tighten the fuel cap. DO
NOT use straight unleaded petrol. From empty the fuel tank holds 800ml.
