Troubleshooting Guide

                            #1 issue is poor battery connection or low charge, so check that first!

The jack runs for a few seconds, then stops…

• The battery is weak or the battery capacity has diminished.
• An auxiliary ground is needed from the tank assembly to the trailer’s frame.

The jack only runs in one direction…

• Check battery voltage.
• Check all wire connections & for proper plumbing.

Press the switch but nothing happens…

• Check both positive & negative 12V connections.
• Check for full charge of battery.
• Check that tank assembly has proper ground.
• Check wiring connections.

The jack is jerky when retracting…

• There may be air in the system, bleed system.
• Low fluid level (Must be 3/4” below top of reservoir)
• Incorrect hose installation.
•  To purge system, add necessary fluid and extend/retract leg completely.

Hydraulic Fluid on footpad or on ground around cylinder...

• Loose fitting or broken hydraulic line.

Cylinders “creep” down or don’t hold pressure when lifting/holding coach…

• Air in the system, see bleeding procedure.
• Check fluid level, should be ¾” below top of reservoir with jacks retracted completely, ATF Dexron III.
• Check for leaks in hydraulic lines/fittings… if lines damaged, replace.

Relief Valves have failed on pump motor… 

• Replace motor/tank assembly

Hydraulic seal failure…

• Replace/return cylinder OR seal kit

Plastic Foaming of fluid or overflow in reservoir….

• Check fluid level of reservoir with legs retracted (should be ¾”-1” below top)

Semi-Annual Service Required: Bleeding the system

Every six months, extend both jacks completely and leave for a

minimum of 30 minutes, then return to standard position.

This is our basic bleeding process, if you have issues with air in the system

(Lifting or holding trailer weight issues) see below for a more detailed process…

1. Disconnect extend hose fitting on the slave jack (jack without pump).

2. Place hose in bucket, run EXTEND on control until smooth fluid flow, stop.

3. Re-connect extend hose fitting on slave jack.

4. Extend both jacks completely (listen to pump), leave for 30 minutes, retract to

normal position.
