Disconnecting the gooseneck from the trailer for loading or unloading shall be conducted with the
gooseneck coupled to the prime mover and the trailer raised.
All persons not involved in the disconnecting operation must stand clear of
prime mover and trailer to prevent serious injury.
To prevent damage to the equipment , the procedure to disconnect the gooseneck
should be performed by a driver working in cooperation with a ground observer.
A reading of 2500 psi is only on gauge (1) when hydraulic controls are in
use. Readings will drop to 500 psi when levers are disengaged.
The psi will vary due to load. Hydraulic pressures will vary from 300 to 2500
psi under normal operation, and will reach a maximum of 2500 to 2800 psi
under full load.
Start up the hydraulic system on the prime mover and observe the appropriate psi on the
hydraulic gauge (1).
