Personal injury or death can result from sudden machine movement. Personnel can be injured during the steering check. To help prevent possible personal injury, keep all personnel away from the machine or in clear view of the operator when the machine is in operation during steering checks.

Before any operational checks are performed, refer to Testing and Adjusting, "Machine Preparation for Troubleshooting" and Testing and Adjusting, "Visual Inspection".
