To confirm the proper function of the automatic shut-off on your Hewitt 1212312N Pressure Activated Aviation Nozzle, perform these steps. First, ensure the fuel dispenser is turned off. Then, place the nozzle spout into an appropriate test container. Next, lift the lever; a small amount of fuel might flow initially. Now, activate the fuel dispenser; the nozzle should remain closed and not dispense fuel. After that, release the lever. Subsequently, lift the lever again and engage the latch clip; the nozzle should now dispense fuel. Following this, switch off the fuel dispenser; the nozzle should immediately stop dispensing fuel. Finally, turn the dispenser back on; the nozzle should once again remain closed, preventing fuel flow. If any issues arise during testing, consult the troubleshooting section of your Hewitt 1212312N nozzle's instruction manual for detailed guidance.
