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 flow 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 6).
Throttle Control
Located on right fuel tank.
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 left side of unit, just to the front 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.
