To preheat the manual oil press (approx. 7 min) and keep it warm during operation (approx. 50 - 70 °C), use the fuel bottle supplied. Fill the bottle 80 % full with a liquid fuel and use a 15 cm long wick. Insert the wick through the lid hole, leaving about 5 mm protruding from the lid and the rest inside the bottle. Once the manual oil press has reached the required temperature, gradually pour your pressed product into the 105 mm funnel and use the ergonomic crank handle to extract the oil, which you collect in the bottle supplied.
