3.1.3 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
counter-clockwise (as viewed from the rear of the machine) to cause the machine
to track more to the right and clockwise 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 section 4.2.10 for control linkage adjustment.
3.1.4 PTO Engagement Switch: Located on the right 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.
3.1.5 Choke Control: Located on the right fuel tank.
Choke is used to aid in starting a cold engine. DO NOT run a warm engine with
choke in the “ON” position.
Moving the choke lever forward will put the choke in the “ON” position and
moving the choke lever to the rear, to the detent, will put the choke in the “OFF”
position.
3.1.6 Throttle Control: Located on the right tank.
Throttle is used to control engine speed. Moving throttle lever forward will increase
engine speed and moving throttle lever to the rear will decrease engine speed.
Moving the throttle forward into the detent is full speed.
3.1.7 Brake Lever: Located on left side of the console. The brake lever engages a
parking brake on the drive wheels.
Pull the lever up and rearward to engage the brake.
Push the lever forward and down to disengage the brake.
The unit must be tied down and brake engaged when transporting.
3.1.8 Ignition Switch: Located on the right tank.
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
against spring pressure in this position).
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.)
3.1.9 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.
3.1.10 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.
