A low charge condition, or any defect in the battery, battery cells, or electrical circuit can cause loss of the secondary steering. The machine's batteries must have a normal charge and the secondary steering electrical system must be in working order. The loss of the secondary steering could result in personal injury and/or damage to the machine. |

|
The alarm system indicates that the primary steering system has failed. Use the secondary steering system to steer the machine to the nearest convenient location. When the machine comes to a complete stop, turn the start switch key to the OFF position. Continuing to operate the machine may result in damage to the system. |
The secondary steering system provides temporary steering control in the event of primary steering failure. Primary steering failure is the result of low oil pressure in the steering system. Primary steering failure can occur for any of the following reasons:
- Hydraulic pump failure
- Engine failure
- Pressure loss in the hydraulic system

Secondary Steering (1) - When this alert indicator is on, the secondary steering is activated. |
|
Primary Steering Malfunction (2) - When this alert indicator is on, the pressure in the steering system is low. |
Alert indicator (2) indicates a failure of the primary steering. When alert indicator (1) 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.
