Operation
Pre-Start
Fill fuel tanks. For best results use only clean, fresh
regular grade unleaded gasoline with an octane rating
of 87 or higher. Regular grade leaded gasoline may
also be used; however, combustion chamber and
cylinder head will require more frequent service. See
Engine Owner’s Manual.
Do Not add oil to gasoline.
Do Not overll fuel tank. Never ll the fuel tank so
that the fuel level rises above a level that is 1/2 inch
below the bottom of the ller neck to allow for fuel
expansion and prevent fuel spillage.
Make sure you understand the controls, their
locations, their functions, and their safety
requirements.
Refer to the Maintenance section and perform all the
necessary inspection and maintenance steps.
Note: After starting the engine and engaging the
hydro drive, if either of the drive wheels acts sluggish
or will not rotate at all, stop engine and refer to
the Hydraulic System Air Purge Procedure in
Maintenance.
