This petrol chainsaw requires a mixture of petrol and 2-stroke oil at 50:1.
The quality of the petrol and oil is extremely important with running and the life of the engine.
Unsuitable fuels or mix ratios that do not comply with the specification can cause damage the engine (piston seizing, excessive wear)
We recommend to run your chainsaw on E5 petrol if possible, and always ensure the fuel is used or disposed of after 30 days have passed.
