Installing the Return Line
The Return Line takes excess Hydraulic Fluid coming out of the Hydraulic Cylinder and sends it back
into the Fluid Reservoir on the Power Unit.
The Return Line is a single piece of ¼ inch, black, polyethylene Tubing with Elbow Compression
Fittings on each end.
Important : The Return Line uses the same ¼ inch, black, polyethylene Tubing as the Air Lines. Be
sure not to confuse the two: the Return Line and the Air Lines do completely different
things and
must be kept separate from each other.
The following drawing shows how to connect the Return Line.
To install the Return Line
:
1. Measure the distance from the
Return Line Port on the Hydraulic
Cylinder to the Hydraulic Return
Port on the Power Unit.
2. 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.
3. 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.
4. Remove the Shipping Plug from the
Return Line Port on the Hydraulic
Cylinder.
5. Connect and tighten the NPT end of
the Elbow fitting to the Return Line
Port and the COMP end connects
to one end of the Return Line.
Use Liquid Thread Sealant on
NPT threads only
.
Refer to
Working with
Compression Fittings and
Tubing
for instructions.
6. Take the second Compression
Elbow Fitting and connect the NPT
end to the Power Unit, and the
COMP end to the other end of the
Return Line (coming out of the Flex
Tube).
