------ WARNING! ------

Personal injury or death can occur if personnel are trapped between the wheel and the frame.

The steering system is hydraulically controlled and wheels can crush personnel during movement.

Use caution when working between the wheels and the frame. If the wheels must be turned, ensure that all personnel are clear of the machine before any movement.


Measure the tire pressure on each tire. Adjust the tire pressure, if necessary. Consult your tire supplier for the correct tire operating pressures and load ratings.
