Operation
Note: Determine the left and right sides of the
machine from the normal operating position.
Controls
Motion Control Levers
The motion control levers located on each side of the
console control the forward and reverse motion of
the machine. The levers control the ow of hydraulic
oil from the hydrostatic pump to the drive wheel
motor for each side.
Moving the levers forward or backward turns the
wheel on the same side forward or in reverse. Wheel
speed is proportional to the amount the lever is
moved.
Moving the levers outward from the center position
into the T-slot locks them in the neutral position
(
Figure 7).
When the motion control levers are in the neutral
position, the LCD indicator appears in the message
display on the center console (see
Figure 6).

Choke Control
Located on the center of the console.
The choke is used to aid in starting a cold engine.
Moving the choke lever forward will put the choke in
the “ON” position and moving the choke lever to
the rear will put the choke in the “OFF” position.
Do Not run a warm engine with choke in the “ON”
position.
Throttle Control
Located on the center of the console (to the left side
of the choke).
The throttle is used to control engine speed. Moving
the throttle lever forward will increase engine speed
and moving the throttle lever to the rear will decrease
engine speed.
Brake Lever
Located on left side of the console.
The brake lever engages a parking brake on the drive
wheels.
Note: The LCD indicator appears in the message
display on the RH console when the park brake is
engaged (see
Figure 6).
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.
Ignition Switch
Located right of center on the console.
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 right of center on the console (below ignition
switch).
