Tag Axle Regulator Adjustment:
The pressure regulator adjustment knob has a positive lock. Pull up on the
knob to unlock, push down on the knob to lock. Tighten or turn the knob
clockwise to increase air pressure. Loosen or turn the knob counterclockwise
to decrease air pressure. When decreasing regulator air pressure the regulator
will release excess air through the regulator discharge port. Each time an
increase or decrease of air pressure to the regulator is made an air pressure
stabilization procedure will also be performed.
The stabilization procedure equalizes the regulator to hold a constant air
pressure setting. To perform the stabilization procedure:
• Start the motorhome and allow the air system to reach a full
charge, indicated by the release of air from the air dryer.
• Raise the tag axle using the tag axle switch on the shift panel.
Allow approximately 20 seconds for the system to discharge air
from the tag axle air bags.
• Lower the tag axle. The regulator will now hold the new air
pressure setting.
• Push down on the regulator adjustment knob to lock the setting.
When increasing the air pressure setting allow approximately a two pound
pressure increase before the stabilization process. Example: If the desired
setting is 30 psi, slowly rotate the regulator adjustment knob clockwise to 28
psi. Perform the stabilization procedure. Regulator setting will stabilize to
approximately 30 psi. When decreasing the air pressure setting rotate the
regulator adjustment knob counterclockwise, allowing the excess air to be
discharged. Next, perform the stabilization procedure.
