Connect the Return Lines
The Return Line returns Hydraulic Fluid from the Hydraulic Cylinders to the Power Unit’s Hydraulic Fluid
Reservoir.
Create the Return Line using the ¼ inch black plastic Tubing that came with the Lift; you need to cut it
into sections of the appropriate length.
Important : The Air Line and the Return Line use the same ¼ inch, black, polyethylene Tubing. Be
sure not to confuse the two; the Air Line and the Return Line do completely different
things and
must be kept separate from each other. The Return Lines may be marked
with tape to positively identify them.
The following drawing shows how the Return Line is routed.

.
To connect the Return Line :
1. Locate three Tee Compression Fittings, four
Straight Compression Nipples (¼ Comp to 1/8-
27NPT), and the black ¼” Air Tubing.
2. Remove the plastic shipping plug in the Cylinder
Return Ports (Cylinder Vents) on all four cylinders.
3. Use PTFE Sealant on all NPT threads and connect
the NPT end of the four Straight Compression
Fittings to the Return Ports on the Lift Cylinders in
the Left and Right Lift Frames and tighten.
