ADJUSTING THE AIR SPRING
1.
Perform the hitching procedure before adjusting suspension air pressure, with the trailer loaded.

With trailer hitched to truck and landing gear / jacks retracted, add air to the air bag fill valve shown in figures 12 and 13.
When filling the system, you must push the air valve into the hard stop to allow the system to take air (approximately 0.25")
3.
Fill until the Goosebox is at its nominal position (seen in the air inflation indicator) (figure 14)
4.
It may be helpful to put tow vehicle in neutral to allow the unit to find its natural position. Then apply brake.
5.
Recheck Air Inflation Indicator / inflate to desired ride comfort position.
6.
The Goosebox is equipped with an automatic air relief valve. If you try to over inflate the bag, the relief valve will pop,
releasing air.
