The ignition switch is used to start and stop the engine. The switch has three
positions "OFF", "ON" and "START". Insert the key into switch and rotate
clockwise to the "ON" position.
Rotate clockwise to the next position to engage the starter (key must be held

and PTO switch "OFF" to start engine. (It is not necessary for the operator to
be in the seat to start the engine.)
4.1.9 Hour Meter: Located on the right tank.
The hour meter is connected to a pressure switch installed in the engine block
and it records the number of hours that the engine has run. If ignition switch is
left on without engine running, hour meter will not run.
NOTE: This switch is not a low oil sensor and will not alert the operator if the
engine oil is low.
4.1.10 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.
4.1.11 Fuel Gauge: Located on the left fuel tank. The fuel gauge monitors the amount
of fuel in the tank.

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 5/8 wrench, turn both valves one turn counter-clockwise to release drive
system.
Turn clockwise to reset system. DO NOT overtighten. DO NOT tow machine.

4.2 PRE-START

4.2.1 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.
4.2.2 Make sure you understand the controls, their locations, their functions, and their
safety requirements.
4.2.3 Refer to Maintenance, Section 5, and perform all the necessary inspection and
maintenance steps.

4.3 MOWING
