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.
This section describes how to connect the other end of the Return Line to the Power Unit.
To attach the Return Line to the Power Unit:
1. Locate the Return Line Connector on the Power Unit and remove the Shipping Plug.
Refer to the drawing on the next page for the location of the Return Line Connector on your Power
Unit.
2. Connect and tighten the threaded end of an Elbow Compression Fitting to the Return Line
Connector on the Power Unit.
For information about connection compression fittings, refer to Working with Compression
Fittings and Tubing.
3. 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; it connects to the Pushbutton Air Valve
.
