Operation
The unit must be tied down and brake engaged when
transporting.
Ignition Switch
Located on right fuel tank.
The ignition switch is used to start and stop the
engine. The switch has three positions “OFF”, “ON”
and “START”. Insert key into switch and rotate
clockwise to the “ON” position. Rotate clockwise to
the next position to engage the starter (key must be
held against spring pressure in this position).
Note:
Brake must be engaged, motion control levers
out (neutral lock position) and PTO switch “OFF” to
start engine. (It is not necessary for the operator to
be in the seat to start the engine.)
Hour Meter
Located on the right fuel 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 the
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.
Fuel Shut-Off Valve
The valve is located in the fuel line beside the engine,
near the fuel filter.
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 counterclockwise to turn
on fuel.
Fuel Gauge
Located on the left fuel tank.
The fuel gauge monitors the amount of fuel in both
tanks. Fuel is used evenly from both tanks.
Drive Wheel Release Valves
Located on the 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 5/8 inch wrench, turn both valves one turn
counterclockwise to release drive system. Turn
clockwise to reset system.
Do Not overtighten. Do
Not tow machine.
Tracking Adjustment Knob
Located under the seat on the LH pump control link.
Rotating this knob allows fine tuning adjustments so
that the machine tracks straight with the drive levers
in the full forward position.
Stop machine and wait for all moving parts to stop.
Engage park brake. Unhook seat latch and tilt seat
forward to gain access to the tracking knob. Rotate
the knob clockwise (as viewed from the rear of the
machine) to cause the machine to track more to the
right and counterclockwise to cause the machine
to track more to the left. Adjust in quarter-turn
increments until the machine tracks straight. Check
that the machine does not creep when in neutral with
the park brakes disengaged.
Important:
Do Not rotate the knob too far, as
this may cause the machine to creep in neutral.
Refer to the Motion Control Linkage Adjustment
section in Maintenance.
PTO Engagement Switch
Located on the 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
