surface. Make sure that surface is capable of holding the weight of
the trailer.
Do not lubricate tubes on jacks. It can attract dirt which could
affect operation of jack.
After all steps are completed, using supplied hardware attach the

Troubleshooting
If jack is not extending or retracting check the following:
- Make sure all electrical connections are secure and battery is
fully charged and grounded.
- Make sure hydraulic fluid is flowing from the HPU unit and
through the lines. Check to make sure there are no leaks or
pinch points in the hoses and all hydraulic connections are
secure.
- If jack retracts after leveled to desired location, check fluid level
in the HPU unit and all connections are secure.
