Common Troubleshooting...

Most tech support common calls

Most issues we receive are power related. Always check power and ground wire connections first. Check
power level of battery under load (place volt meter on battery then press and hold EMERGENCY RETRACT on
control to see if voltage drops).

Alarm going off with engine on

Typically this means one of the cylinder limit switches sent the signal to the controller that it was "up" before
it was 100% retracted (footpad tight to bottom). So when you hit a bump or vibration while driving, this
caused the limit switch pin to loose contact and sound the alarm. First visually inspect and make sure they are
all retracted, then do the following: Auto system: Press & hold EMERGENCY RETRACT button for a few
seconds, you will hear the pump change tone or ALL UP light to come on. Platinum system: Enter RETRACT
mode, then press and hold each cylinder button individually for a few seconds, listen for pump change tone or
ALL UP light to come on.

System will not operate with engine on

Our systems are NOT designed to extend with the engine on for safety. They will also not automatically retract
when the engine comes on.
Cylinders not lifting or holding pressure
This means there is more than likely air in the system (not bleed during installation). Two methods, easy
method is to enter manual mode and completely extend all four cylinders to full extension and leave for an
hour, then retract, wait another 30 minutes before operating again. If this does not fix the issue then the
secondary bleeding procedure must be done, see below for instruction.
Cylinder will not operate, extend or retract...
Attempt to bleed system first, verify that it will not operate in either direction. Then check all wires at the leveling sensor
to make sure they are inserted properly in the plug at the back of the sensor (wires may be loose in connector). If this is
all good, then the corresponding valve/coil may be defective, in tank assembly check valve ground wire (to solenoid
mounting bolt) and wire connection to wiring pigtail. If valve bad, part #M35008, take care replacing do to ease of
crushing valve assembly on re-installation.
Secondary air bleeding process
If there is still air in the system, a more strategic method may be required. Loosen all four extend hose fittings
(15mm wrench) on the jacks (located near the top of each cylinder), enough that fluid and air can escape.
Enter manual mode on panel (press and hold MANUAL for 3 seconds until light comes on). Press and hold each
cylinder until solid fluid comes out of each fitting. Tighten fittings and repeat for retract hose fittings to ensure
all air is out, to retract cylinders in manual mode, press each cylinder and the RETRACT button simultaneously.
Re-tighten all fittings and clean up mess. This method can also be done by placing each line in a bucket to
minimize mess afterwards.
In some instances, the front jacks may need to be dis-mounted from underneath the cab to access
the top extend ports during the bleeding procedure.
CAUTION WHEN OPERATING:
Rear tires must maintain contact with the ground as
the bolt-on system is not designed for this and the
jacks may shift. Front tires are typically OK to leave the
ground, as they may need to do so to level.
