Operation

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).

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.

Choke Control

Located on right console (black lever) (see Figure 6).

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.

Note: The LCD indicator appears in the message display on the RH console when the park brake is engaged (see Figure 9).

Pull the lever up and rearward to engage the brake.

Depress the release button and push downward to disengage the brake.
