HOW TO USE THE GARDNER-GOODMAN STOPPER 

  1. To insert the Gardner- Goodman Stopper, screw the container hand tight into the main. The bag should be entirely within the tube while this is being done.

  2. Push plunger piston down to stop collar.

  3. Inflate bag slowly with ordinary tire pump. (Slow inflation gives bag time to shape up.)

  4. WATCH THE GAUGE.

  5. To remove Stopper from main: Remove vent plug and allow bag to deflate. Slowly pull bag up into container. Unscrew.
