CONNECTING GOOSENECK TO TRAILER (Continued).
Connect the 12/24 volt electrical cable (8) between the trailer and the gooseneck.
With the hydraulic system pressurized to the appropriate psi on the gauge (6), move the
platform lever (13) to the up position to raise the trailer bed to a position slightly above the
desired height. Using the shim lever (7), position the shims in the appropriate notch of the
baseplate (14) to maintain the trailer height and lower the trailer bed slightly to lock the
shims in place.
A reading of 2500 psi is only on gauge (6) 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.
Using the gooseneck support lever (12), raise the tilt arm (11).
Move prime mover and trailer forward slowly and apply brakes to check for proper braking
action. The system is ready for operation.
