Manual Control Panel: Plug the 14-pin harness & 6-pin into back of panel, mount with bezel, not weatherproof control
or wire connection, mount inside with supplied #6 black screws. 6-pin has black needs ground, red to 12v constant and
yellow to ignition hot.
Central Pump
Final Extend Hose Installation & Bleeding the System
During installation of the hydraulic lines, air is internally captured in the hose. Due to this, bleeding the air out of the
system is necessary for the system to work properly. This process is done at the end of installation and requires two
people and can be messy, so as a warning make sure you are wearing eye protection and have rags ready to use. Make
sure all hose fittings are tight on the pump side and the retract side of the jacks. Extend hose fittings should still be un-
installed.
- With person #1 running the panel, go into Manual Mode, all jacks should be fully retracted.
- Person #2 (armed with a 5/8” OR 9/16” wrench, safety glasses, rag and a one gallon container) needs to access the left
rear jack and place the un-attached extend hose into the empty container.
- Now person #1 will extend that left rear jack from the panel (press & hold button).
- Fluid & air will be spilling out of the port, once a solid stream of fluid occurs, person #1 will release the button on the
panel, after fluid stops flowing person #2 should install the hose fitting to the jack.
- Repeat these steps with the rest of the jacks.
- After doing so, extend all jacks fully and let stand for 15 minutes.
- Then retract all the jacks and remove the tank cover and check your fluid level to verify the fluid in the reservoir is
around 1 ¾” below the top (ATF Dexron III) do not fill to the top!
Finally install the tank cover, check that all hardware is tight, the sensor is facing the correct way and is mounted level
and the house battery is fully charged.
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.

systems
In Manual mode, extend all four jacks to complete extension and leave in this position for 20 to 30 minutes. This pushes
all the air out of the lines by weight pressure. After turn panel back on and press Retract.
Troubleshooting - Hydraulic Cylinder/Plumbing Related
What fluid do we use in the system? Automatic Transmission Fluid Dexron III ATF
Cylinders running “choppy”… Bleed the system, if central pump system, try quad pump method first.
Cylinders make loud “squeaking” noise while operating…
Spray rams with Teflon spray (dry lubricant).
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…
Check fluid level, Check for leaks in hydraulic lines/fittings
Possibly plumbed backwards… (Bottom port on cylinder tube connects to right port on pump, etc.)
Relief Valves have failed on pump motor… replace motor/tank assembly
Hydraulic seal failure, check for oil around bottom of cylinder or welds… replace cylinder
