How It Works

  1. Turn on unit (red light will glow). Allow about 30 minutes for selected temperature to stabilize. (Note: temperature control is not regulated by degrees. Set control to 50; try tubing. Increase or decrease heat as necessary.) Leave tube on jaws long enough to soften material before expanding.

  2. Place tube on jaws, step on foot pedal. Jaws will separate and spread tubing.

  3. Release foot pedal and jaws will close. Remove tube from the jaws.

  4. Immediately insert fitting into tube.
