INSULATION 2378417 - 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.
Extended operation of the secondary steering motor could damage the motor and result in loss of emergency steering capability, which could cause injury or death. The Secondary Steering System should not be used for towing the machine or for other service procedures lasting longer than 5 minutes. The motor should be allowed to cool to ambient temperatures before reuse.
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.
Note: This test should be conducted when the truck is empty.
