Air Coupler - Universal; Air Spring Inspection - Monaco Cayman 2005 Owner's Manual

Air Coupler - Universal

Provided for convenience is a remote air supply coupler, located in the front roadside electrical
compartment. This female fitting will accept type C automotive male air fittings. The auxiliary air fitting
may be used to inflate tires, air mattresses or other pneumatic items. This fitting is not designed to
charge the air system on the motorhome. The air supply for the auxiliary air fitting is charged from the
air tank through a pressure protection valve.
To Use the Universal Air Coupler:
• Remove the plastic protective dust cap.
• Using a firm grip, insert the air fitting into auxiliary air supply.
The locking collar is spring loaded and will lock automatically
when the fitting is properly inserted.
To remove fitting:
• Firmly grip the air hose near the fitting to prevent recoil.
• Slide the locking collar back to release fitting. The collar will lock
into the open position when fully retracted.
• Replace the protective dust cap when finished.
NOTE:
There are small air pressure restrictions in the pressure protection valve and tire
stem valve. Due to this restriction, the maximum amount of tire pressure achieved
when the system is used to fill a tire is approximately 95 to 105 psi, with the air
system on the motorhome charged to 120 psi.
Air Spring Inspections
Listed below are items that can be checked when the motorhome is in for periodic maintenance.
NOTE:
Never attempt to service the air suspension on a
motorhome with the air bags inflated.
• Inspect the outside diameter of the air springs. Check for signs of irregular wear or heat
cracking.
• Inspect the air lines to make sure contact does not exist between the air line and the outside
diameter of the air springs. Air lines can rub a hole in an air spring very quickly.
• Check to see that there is sufficient clearance around the complete circumference of the
air spring while at its maximum diameter.
• Inspect the outside diameter of piston for buildup of foreign materials. (On a reversible sleeve
style air spring, the piston is the bottom component of the air spring.)
