Purchase Alcohol with a Concentration of 95%. the Alcohol with a Concentration Lower Than 95% Has a Low Combustion Value, Which May Cause the Engine to Fail to Operate Normally2. Add About Twothirds of the Alcohol in the Alcohol Lamp (cannot Be Topped Up, It Will Overflow when It is Topped Up)3. Then Ignite the Alcohol Lamp to Preheat the Heating Cylinder, About 2 Minutes, After the Preheating Time is Almost the Front End of the Trolley Shall Prevail; Turn the Flywheel Clockwise to Give the Engine an Initial Power, Otherwise the Engine Will Not Run (turn the Flame Larger and when You Turn the Flywheel a Little Harder, the Engine is Easy to Start)/pstyle .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }/stylep/pp/pp/p/p
