CONNECTING GOOSENECK TO SEMITRAILER - Continued
4.
Connect air lines (Figure 13, Item 4 and 5) between semitrailer and gooseneck.
5.
Connect 12/24-volt electrical cable (Figure 13, Item 3) between semitrailer and gooseneck.
WARNING
Place towing vehicle Power Take-Off (PTO) switch in low idle position for hydraulic
operations to avoid over pressurizing the hydraulic system on the semitrailer. Failure to
comply may result in death or injury to personnel. Seek medical attention in the event of
an injury.
NOTE
A reading of 900 psi (6,205.3 kPa) is only on gage when hydraulic controls are in
use. Readings will drop to 500 psi (3,447.4 kPa) when levers are disengaged.
The psi will vary due to load. Hydraulic pressures will vary from 300 to 900 psi
(2.068.4-6,205.3 kPa) under normal operation, and will reach a maximum of
900 to 1,100 psi (6,205.3-7,584.2 kPa) under full load.
6.
With hydraulic system pressurized to appropriate psi on gage (Figure 13, Item 1), move platform lever
(Figure 13, Item 8) to up position to raise semitrailer bed to a position slightly above desired height.
7.
Using shim lever (Figure 13, Item 2), position shims in appropriate notch of baseplate (Figure 14, Item 1) to
maintain semitrailer height and lower semitrailer bed slightly to lock shims in place.
