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.
Moving the levers forward or backward turns
the wheel on the same side forward or reverse
respectively. 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 5).
When the motion control levers are in the neutral
position, the LCD indicator appears in the message
display on the RH console (see Figure 9).

Choke Control
Located on right console (black lever) (see Figure 6).
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, to the detent, will put the choke in the “OFF”
position. Do Not run a warm engine with choke in
the “ON” position.

Throttle Control
Located on right console (red lever) (see Figure 6).
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. Moving the throttle forward into the
detent is full throttle.
Brake Lever
Located on right side of unit, just to the front of the
RH motion control lever.
The brake lever engages a parking brake on the drive
wheels.
