UNIVERSAL JOINT GP 3W2413 - Caterpillar

Personal injury or death can occur if steering is lost completely during operation.Do not continue to operate the machine using the secondary steering.If the secondary steering activates during operation, immediately park the machine in a safe location. Inspect the machine and correct the condition which made the use of the secondary steering necessary.
The secondary steering switch should always be in the AUTO position during normal operation. This will ensure that secondary steering capability is immediately available if the primary steering system fails.
To minimize battery drain, leave the switch in the MANUAL position only long enough to test the secondary steering. Return the switch to the AUTO position immediately after testing.
