- The machine is in motion.
- The engine start switch key is in the ON position.
- The steering oil pressure is low or the steering oil pressure is not available.
The secondary steering indicator will come on for three seconds when the engine start switch key is in the ON position. The primary steering indicator will come on for three seconds when the engine start switch key is in the ON position. During this time, the operator can determine if the pump motor for the secondary steering is engaged and the operator should try to steer the machine. The alarm for the secondary steering will not sound when the engine start switch is first placed in the ON position.
If the alert indicator does not come on or you are unable to steer the machine, do not operate the machine. Correct the cause of the failure before you operate the machine again.
The secondary steering indicator will come on and the electric motor will activate when the following conditions occur.
- The secondary steering control senses a lack of oil pressure.
- The drive shaft speed is greater than 200 rpm or the engine speed is greater than 1600 rpm.
- The direction control lever is in FORWARD or REVERSE or the direction control switch (if equipped) is in FORWARD or REVERSE.
The alarm for the secondary steering will sound when a primary steering failure occurs.
The secondary steering system will deactivate when the secondary steering control senses one of the following conditions.
- Oil pressure has been returned to the system.
- The ground speed is zero.
If the primary steering indicator comes on, steer the machine to a convenient location and stop the machine.
Make any necessary repairs before you return the machine to operation.

The primary steering indicator (1) indicates that the primary steering has failed. The secondary steering indicator (2) indicates that the secondary steering system is activated.
Push the secondary steering switch (3) to the ON position and hold the secondary steering switch in the ON position in order to articulate the machine when the engine is stopped. Push the secondary steering switch to the ON position and hold the secondary steering switch in the ON position in order to articulate the machine when the machine is being towed.
Push the secondary steering switch in order to determine if the secondary steering and the alert indicators are functional.
When the alert indicators come on, steer the machine immediately to a convenient location and stop the machine. Stop the engine and investigate the cause. Do not operate the machine until the cause has been corrected.
Note: If the hydraulic system functions are used at low engine speeds, the alert indicator may come on momentarily.
