HELPFUL TIPS: AIR LINE AND FITTINGS
1. Minimum hose bend radius
•
3/8” hose = 1.5” hose bend radius.
•
1/4” hose = 1” hose bend radius.
2.
Hose to fitting
•
No side loading on fitting from hose.
•
Hose straight for 1” before bending.
3. Hose cutting
•
Cut hose perpendicular to hose length.
•
Inspect hose for scratches that run lengthwise on hose prior to insertion.
•
Use proper hose cutter, cigar cutter, or razor on flat surface.
4.
DOT/SAEJ844 air brake hose data
•
Maximum working pressure of 175 PSI.
•
Not to be used for frame (body) to un-sprung mass connection, use a braided leader
hose for this moving connection.
AutoPilot V2 is an advanced pressure-based air suspension control system, that uses state-
of-the-art software algorithms to calibrate or map the control system to your vehicle. Once
the system is calibrated, the algorithm predicts required “valve open time” to move the air
suspension to achieve preset target pressures. AutoPilot V2 has 8 programmable presets,
allowing the user to input 8 different combinations of the 4 corner air spring pressures.
After installing AutoPilot V2 in your vehicle, please follow the steps below to properly setup
your new system. If changes are made after installing and calibrating the system such as
changes to air springs, lines, tank, compressor, or other vehicle modifications, the system
must be recalibrated to maintain accuracy.
