EZ Air Automatic Tire Deflators: instructions

Four deflators per set. Range: 6 to 30 PSI.

Set them (once, then they remember)

1. Deflate one tire to the pressure you want, with a gauge.
2. Wind the lock ring and adjusting cap down, then screw the deflator onto a clean valve stem with good threads.
3. Loosen the cap (counterclockwise) until the deflator pops open, then tighten it right away to the point where air stops.
4. Turn the lock ring up against the cap to hold it. That deflator is now set.
5. Set the other three to match. Each half turn of the cap changes the setting by about 3 PSI.

Use them

1. Screw one deflator on each tire. Air starts leaving on its own.
2. Wait. Each one stops when its tire reaches the set pressure.
3. Remove them and check one tire with a gauge.

If the tire is already within about 8 PSI of the setting, the deflator may not start by itself: fit it, then lift the center pin to start it.
