Installing the Flex Tube
The Flex Tube is a flexible, black plastic tube that attaches to the bottom of the Flex Tube Bracket
(next to the Power Unit) on one end and to a hole on the Powerside Runway on the other end.
The Flex Tube protects the Hydraulic Hose and the Return Line as they go from the Power Unit to
underneath the Powerside Runway.
The following drawing shows the Flex Tube.
Side view. Not drawn to scale. Not all components shown.
To install the Flex Tube to the Flex Tube Bracket:
1. Make sure the Flex Tube Bracket has been installed next to the Power Unit.
2. Unscrew the Plastic Nut from one end of the Flex Tube. It does not matter which end.
3. Holding the Flex Tube by the Plastic Collar, put the Threads on the end of the Flex Tube through
the hole at the bottom of the Flex Tube Bracket.
The Threads go through the hole until they are accessible from the other side, while the rest of the
Flex Tube stays outside.
4. Screw the Plastic Nut back onto the Threads of the Flex Tube and tighten it.
5. Unscrew the Plastic Nut from the unconnected end of the Flex Tube.
6. Holding the Flex Tube by the Plastic Collar, push the Threads through the hole on the side of the
Powerside Runway.
7. Screw the Plastic Nut back onto the Threads on the Flex Tube and tighten it.
