BEFORE EACH TRIP:
1. CHECK YOUR EQUIPMENT: Check that condition of all of your towing equipment and keep it in top condition.
2. Check to see that all bolts are properly tightened.
4. Check that the airbag pressure is set for your coach. (The skid plate should be near level when parked on level ground)
MAINTENANCE:
1. For ease of hookup; frequently lubricate the skid plate surface and the back side of the king pin.
2. Keep pin-box hitch painted to prevent rust and maintain a good appearance. (Do Not paint over labels)
ADJUSTING THE AIR SPRING
1. Perform the hitching procedure following the proper hitching procedure according to the manual for your fifth wheel
Hitch.
2. Add air to the air spring at the valve shown in figure 8. Continue adding air until the skid plate is level (on level ground) see
figure 8. (Use the Inspection Notch on lower jaw of the pin box and line up with bottom side of body.)
The inspection notch is a good reference for setting air pressure in the spring, if more performance is desired the air
bag position and pressure can be adjusted to suite your preference. The air spring position can be adjusted by
loosening the mounting bolts shown in figure 7 and moving the bag as indicated per your loading condition. A good
starting point for pressure setting is 80-100 psi. (Do Not Exceed 120 psi). If the ride is too soft, add more pressure.
If the ride is harsh, remove pressure. If the pressure adjustment cannot maintain a satisfactory ride, reposition the
air spring according to figure 7.
