WARNING
The machine is not stable when towing it with the
axle in the narrow position.
Tow the machine with the axle in the wide position.
Important: Adjust the axle to the narrow position only
to move the machine through a narrow access point,
such as the gate of a fence or the doorway of a building.
Preparing to Change the Axle Width
1. Move the machine to a level job-site surface.
2. Disconnect the machine from the tow vehicle.
3. Chock the tires.
4. Ensure that the drum is empty and in the mix position
(upright).
5. Ensure that the drum latch is engaged and that the
drum does not rotate toward the dump position.
Adjusting the Axle Width
WARNING
Mechanical or hydraulic jacks may fail to support
the machine and cause serious injury.
Use jack stands when supporting the machine.
1. Align a jack with an adequate lift height and weight
capacity under the axle; refer to Specifications (page
13).
2. Lift the machine until the tires are off the ground.
3. Use a jack stand at each support point on the rear
frame extension (Figure 27).
