ATTENTION

DO NOT start engine without dry. It will damage the fluorine piston ring and therefore lose cylinder pressure. PAY ATTENTION to the work of cooling system. Make sure it’s working.

Break-in:

Proper break-in is a must-be for good performance and life. It needs to change oil every 10 minutes total runtime at the first 3 oil changes. Make sure it runs with enough cooling and oil.

Maintenance:

Change oil every 20 minutes total runtime to keep engine in good form.
