Operation
Drive Wheel Release Valves
Located on the top right front corner of hydrostatic
pumps.
Drive wheel release valves are used to release the
hydrostatic drive system to allow the machine to be
pushed without the engine running. Unhook seat
latch and tilt seat up to gain access to pumps.
With a 7/16 inch wrench, turn both valves one
turn counterclockwise to release drive system. Turn
clockwise to reset system. Do Not overtighten. Do
Not tow machine.
PTO Engagement Switch
Located on right fuel tank.
Switch must be pulled out to the “ROTATE”
position to engage the blades. Switch is pushed in to
the “STOP” position to stop the blades.
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 overfill fuel tank. Never fill the fuel tank so
that the fuel level rises above a level that is 1/2 inch
(13 mm) below the bottom of the filler 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.
