Air Lift Performance
Now that your system is set up, it’s time to use it. If changes are made after installing and
calibrating the system such as changes to air springs, lines, tank, or compressor, the system
must be recalibrated to maintain system accuracy.
There are two operational modes: PRESET and MANUAL. Pressing buttons (1+5)
simultaneously will toggle between modes. After 10 seconds of non-use, the display enters
standby where the LCD dims. Any button hit will “wake-up” the display and allow users to
activate the system. See mode operation below for more details.
PRESET Mode
1. If display is sleeping, press any button once to “wake up” the display. If display is
illuminated, go to the next step. Press of any button will display the programmed preset
pressures for that button. Users can quickly view each preset prior to activating to make
sure they are selecting the desired preset.
2. A 2
nd
button press of the same preset button within 2 seconds will activate it. The system
will iterate up to 6 times to achieve the preset target pressures by +/- 3 PSI. The display
shows PLEASE WAIT as it iterates, then will flash SUCCESSFUL when achieved or
UNSUCCESSFUL if not able to achieve the target pressure window.
3. Micro adjust to ±1 PSI: If more accuracy is desired, double press the same preset and
the system will refine pressures closer to target. This is often necessary when target
preset pressures are LOWER than current pressure. Accuracy can be improved by
rolling the vehicle straight while activating the preset.
If the system indicates UNSUCCESSFUL, refer to troubleshooting guide on page 13.
PRESET Mode: Improve Accuracy
If system reads SUCCESSFUL but pressures are consistently lower or higher than target,
you can improve first attempt accuracy by going to Calibration Menu (fig. 5) and pressing
button 2. Adjust the ADJ value to a higher number if first attempt pressures are lower than
target. Adjust the value to a lower number if first attempt pressures are higher than target.
WHEN A PRESET IS ACTIVATED THAT LOWERS THE VEHICLE SIGNIFICANTLY BELOW
DRIVING HEIGHT, BE SURE TO HAVE THE FRONT WHEELS STEERED STRAIGHT
AHEAD TO AVOID FENDER TO TIRE DAMAGE!
