3.1.9 Fuel Shut-Off Valve
: Located In the fuel line midway between the fuel tank and the
engine behind seat.
The fuel shut-off valve is used to shut off the fuel when the machine will not be used
for a few days, during transport to and from the jobsite, and when parked inside a
building.
Rotate the valve 1/4 turn clockwise to shut off fuel. Rotate the valve 1/4 turn
counter-clockwise to turn on fuel.
3.1.10 Drive Wheel Release Levers
: Located at the rear of the mainframe. The release
levers are used to release the hydrostatic drive system to allow the machine to be
pushed without the engine running. Pull each lever rearward and outward to lock.
Pull each lever inward and push forward to reset. DO NOT tow machine.
3.2 PRE-START
3.2.1 Fill fuel tank. 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” below the bottom of the filler neck to allow for fuel expansion and
prevent fuel spillage.
3.2.2 Make sure you understand the controls, their locations, their functions, and their safety
requirements.
3.2.3 Refer to Maintenance, Section 4, and perform all the necessary inspection and
maintenance steps.
3.3 MOWING
3.3.1 Open fuel shut-off valve:
The fuel shut-off valve is located under the seat in the fuel line between the left fuel
tank and the engine.
3.3.2 Starting Engine:
Brake must be engaged, the PTO switch disengaged, and the motion control
levers out (neutral lock position). (The operator does not need to be in the seat to
start the engine.)
On a cold engine, place the throttle midway between the “SLOW” and “FAST”
positions and place the choke to the “ON” position. Turn ignition switch to the “start”
position. Release the switch as soon as the engine starts.
IMPORTANT:
DO NOT crank the engine continuously for more than ten (10)
seconds at a time. If the engine does not start, allow a 60 second cool-down
period between starting attempts. Failure to follow these guidelines can burn
out the starter motor.
After starting a cold engine, gradually return choke to the “OFF” position as the engine
warms up.
On a warm engine, place the throttle midway between the “SLOW” and “FAST”
positions and leave the choke in the “OFF” position.
