Removing Gasoline from the Fuel Tank
1.
Stop the engine, allow it to cool and disconnect the
spark plug wire. Remove the key switch on electric
start models.
2.
Remove the cap from the fuel tank and use a pump
type siphon to transfer fuel into a clean gas can
or
container designed to hold gasoline. Note: this is the
only fuel removal procedure that should be used for
general maintenance.
Changing Crankcase Oil
Change the oil after the first
2
operating hours and after
every
25
hours. Since warm oil will drain better and carry
more contaminants than cold oil, run the engine for a
5
minute period before draining the oil.
