Secondary Steering - If Equipped

Illustration 1g00478320

Alert indicator (1) indicates a failure of the primary steering. When alert indicator (2) flashes, the secondary steering system is active. When the alert indicators come on and the action alarm sounds, steer the machine immediately to a convenient location and stop the machine. Stop the engine and investigate the cause of the failure. Do not operate the machine until the cause of the failure has been corrected.

The AVSpare Monitoring System will perform a self test of the secondary steering during engine start-up. Alert indicator (2) will come on for three seconds in order to verify the pressurization of the secondary steering system. The action alarm will sound until the end of the self test or until the engine is started.

The secondary steering system can be tested manually. Push the secondary steering switch in order to determine whether the secondary steering system and the alert indicator are functional. When the secondary steering switch is pushed, the secondary steering motor will run. Alert indicator (2) will come on and the action alarm will sound. If alert indicator (2) does not come on or the action alarm does not sound, do not operate the machine.


NOTICE

The alarm system indicates the steering system has failed. When the alarm sounds, bring the machine to a safe stop immediately.

Use the secondary steering system only in an emergency.

DO NOT use the secondary steering system as a limp home mode procedure.

Continuing to operate the machine may result in damage to the system.
