HDS-14LSX / HDS-14LSXE Lifts 29 P/N 5900162 — April 2018 — Rev. F3
The following drawing shows the Return Line.
Drawing not to scale. Some components not shown. Some components exaggerated.
To install the Return Line:
1. Attach an air pressure source to the Return Line Connector on the Hydraulic Cylinder and extend
the Cylinder’s Piston and Tie Plate until it is fully extended towards the Power Post.
This step does not apply to installing the Return Line, but it does need to be done at this
point in the Lift installation.
Do not exceed 50 PSI
. If the Cylinder does not move, stop using air pressure; instead, use a
pulling device (such as a Come Along Tool) to extend the Piston and Tie Plate. Be careful not to
damage the Piston or the Tie Plate.
2. Measure the distance from the Return Line connector on the Hydraulic Cylinder to the Return Line
connector on the Power Unit.
3. Cut a piece of Tubing to the measured length from the roll of Tubing that comes with the Lift.
It is better to cut the Tubing a little too long rather than a little too short.
4. Route the Tubing from the Hydraulic Cylinder, through the Retaining Rings on the underside of the
Powerside Runway, through the Flex Tube, and out next to where the Power Unit will be installed
(see the drawing on the previous page).
You need to route the Return Line through the Retaining Rings so that it is out of the way of where
the Cables will be routed.
5. Remove the Shipping Plug from the Return Line Connector on the Hydraulic Cylinder.
6. Connect and tighten the threaded end of an Elbow Compression Fitting into the opening where the
Shipping Plug used to be.
7. Connect one end of the Return Line to the Elbow Compression Fitting you just installed.
Refer to Working with Compression Fittings and Tubing for instructions.
8. Leave the Power Unit end of the Return Line hanging out of the Flex Tube for now.
It will be connected to an Elbow Compression Fitting and to the Power Unit later in the installation.
