1. Remove adjustment screw & spring while noting the number of turns the adjustment screw was inserted. Remove ball valve by blowing air into the knurled end of the deflator. Keep one hand over the open end to catch the ball and prevent loss. Make every effort to keep the components of each deflator together for
reassembly later.

2. Thoroughly clean inside the deflator’s bore with a Q-tip and rubbing alcohol, then compressed air. Clean all components with
rubbing alcohol and compressed air.

3. Apply a fine coating of a high quality, heavy silicone or teflongrease or Vaseline, or a similar lubricant to each ball valve.

4. Insert the stem of the ball valve into one end of the spring and slide this assembly into the deflator, ball end first.

5. Install adjustment screw (the same number of turns before it was disassembled).
