HD-9 Series Four-Post Lifts 52 P/N 5900123 — Rev. M1 — March 2020
Connecting the Return Line
The Return Line should already be routed through the Flex Tube and connected to the Return Line
connector on the Hydraulic Cylinder; the other end of the Return Line needs to be connected to the
Power Unit.
To attach the Return Line to the Power Unit:
1. Find an Elbow Compression Fitting (04 COMP – 06 NPT) from the Parts Bag.
2. Locate the Hydraulic Return connector on the Power Unit and remove the Shipping Plug.
See Connecting the Power Source for the possible connector locations.
3. Connect and tighten the threaded end of the Elbow Compression Fitting to the Hydraulic Return
connector on the Power Unit.
For information about connection compression fittings, refer to Working with Compression
Fittings and Tubing.
4. Find the Return Line coming out of the Flex Tube and connect it to the other connector on the
Elbow Compression Fitting.
Important: The Air Line, at one point, was also coming out of the Flex Tube and it uses the
same kind of tubing as the Return Line. The Air Line should have been connected in
the previous section, but if it was not, make sure you are attaching the Return Line
to the Power Unit and not the Air Line.
Do not attach the Air Line to the
Power Unit by mistake
.
Connecting the Hydraulic Hose
The Hydraulic Hose connects to a Hydraulic Power Out connector on the Power Unit; the Curved end
of the Hydraulic Hose is already connected to the Hydraulic Cylinder, the other end should be coming
out of the Flex Tube.
To connect the Hydraulic Hose:
1. Find the Hydraulic Fitting (04 JIC – 06 ORB). The Hydraulic Hose is already in place, with the
Straight end coming out of the Flex Tube.
2. Locate the Hydraulic Power Out connector on the Power Unit you want to use and remove the
Shipping Plug.
See Connecting the Power Source for the possible connector locations.
3. Connect and securely tighten the ORB end of the JIC – ORB Fitting to the Hydraulic Power Out on
the Power Unit.
4. Connect and securely tighten the JIC end of the JIC – ORB Fitting to the Hydraulic Hose coming
out of the Flex Tube.
