What is the first step for retracting the stabilizers?

The process of retracting stabilizers begins with ensuring that safety measures are observed, which involves the removal of safety pins from the jacks. Safety pins are critical components that prevent accidental movement of the stabilizers while on the ground. If the pins are not removed, the stabilizers may not be able to retract properly, leading to potential mechanical issues or unsafe conditions during operation.

By removing the safety pins first, it allows the hydraulic system or mechanical linkages associated with the jacks to function correctly. Once the safety pins are out, the next steps, such as operating the stabilizer controls to actually retract the stabilizers or moving the selector valve, can be performed safely and effectively.
