Quick Start and Precautions: 1 Place the engine on a flat table and add hot water with more than 4/5 capacity of the cup into the flat cup with a mouth less than 88mm. 2 The engine will not start automatically. Under the premise of enough safety place the engine on the mouth of the cup and heat it for about 20 seconds then move the flywheel clockwise by hand until the engine runs. 3 It is forbidden to add oil into the engine cylinder piston bearing connecting rod and other moving parts! 4 The engine can run with only a very small temperature difference between the top and bottom anything hotter than boiling water will damage the device. Do not place it on any objects with high temperature (stove wood burning fireplace candle etc.) otherwise many parts of the engine will be melted.The highest temperature to run the HZZ92 engine should not exceed 100C(212F).
