2.0 Installation
Ensure all five (5) rubber feet are completely stabilized on your work surface prior to applying
air pressure to the unit.
2.1 Air Supply
Connect a 1/4” air supply hose to the inlet on the pressure regulator. The air supply
should be free of moisture and contaminates and provide a minimum of 100 psi (+/- 10%)
The regulator on the unit should be set to 80-120 psi.
3.0 Operation
3.1 Tube Expanding
Using Figure 3.1.1, follow the steps below to achieve proper expanding size.
To adjust the jaws for the size tubing to be expanded you need to loosen the 3/8” hex nut
(Lock Nut).
With the compressed air attached to the expander, actuate the foot pedal which will
activate the expander. Keeping the foot pedal down adjust the expander lower jaw to the
position you want using the Thumb Wheel Knob.
Turning the Thumb Wheel clockwise will increase the jaw expansion size, counter
clockwise will decrease the jaw expansion size. This adjustment may require fine tuning
depending on your tubing I.D., O.D., durometer and/or material.
Once you have the expansion size you want tighten the Lock Nut to secure the
adjustment. Release the foot pedal.
Place the tube over the ends of both expander jaws and hold firmly in place.
Actuate the Tube Expander by pressing the foot pedal.
Once the tube is expanded, release the foot pedal, rotate the tubing 90 degrees on the jaws
and actuate the Tube Expander by pressing the foot pedal again.
Note: Several expanding actions may be necessary to effectively expand the end of
the tube for the fitting/connector to slide in. Each time you expand the tubing
remember to rotate the tubing 90 degrees on the jaws.
Quickly insert the component or tube connector before the tubing regains its original
size.
