To confirm the proper function of your Hewitt 1212312N Pressure Activated Aviation Nozzle's automatic shut-off feature, perform this test: 1. Ensure the fuel dispenser is switched off. 2. Place the nozzle spout securely into a test container. 3. Initially, lift the lever; a small amount of fuel may briefly flow until line pressure decreases. 4. Activate the fuel dispenser; the nozzle should remain closed and not dispense fuel. 5. Release the lever. 6. Lift the lever and engage the latch clip; the nozzle should now dispense fuel. 7. Shut off the fuel dispenser; the nozzle should immediately stop dispensing fuel. 8. Turn the dispenser on once more; the nozzle should once again remain closed, preventing fuel flow. If any problems arise during testing, consult the troubleshooting section of your Hewitt 1212312N nozzle's manual for detailed assistance.
