INSTRUCTIONS FOR USE:
If using a dual head type tire chuck with an inflator gauge and notice air is escaping through the off-side once connected to the tires Schrader valve, simply release the trigger and remove the inflator from the Schrader/tire valve. Point the straight side of the outlet up into the air (make sure its not pointed at someone). Squeeze trigger, allow air to flow (gravity will cause the sealing valve to drop), and place the chuck end onto the Schrader/tire valve while air is still flowing. Air will start to flow into the tire.
Dual head type tire chucks are unable to inflate a completely flat (zero air pressure) tire. Tire air pressure would normally cause the sealing valve to move and seal the unused side of the chuck. However, if a tire has 0 air pressure, the self-sealing valve has no pressure to react to.
This hose whip is free-flowing and cannot be used without the Bayonet Inflator Gauge- Air is turned on/off by the bayonet controller. If connected directly to an air source, air will constantly flow out.
