4. Setup

4.1 Connecting to an Air Compressor

Ensure your air compressor is off and depressurized.
Apply the provided thread seal tape (PTFE tape) around the threads of the 1/4" NPT air inlet connector on the inflator. Wrap the tape in the direction of the thread spiral (usually clockwise) for a good seal.
Securely attach the inflator's 1/4" NPT air inlet to your air compressor's hose or quick-connect fitting. Use appropriate tools to tighten the connection, ensuring no air leakage.

5.1 Checking Tire Pressure

Remove the valve cap from the tire valve stem.
Firmly press the inflator's chuck onto the tire valve stem. Ensure a tight seal to prevent air leakage.
The bayonet-style pressure gauge will immediately display the current tire pressure.
Compare the reading to your vehicle's recommended tire pressure.

6. Maintenance

Regularly inspect the hose and connections for any signs of wear, cracks, or damage. Replace components as needed.
Keep the inflator clean and free of dirt, dust, and debris. Wipe with a dry cloth after each use.
Ensure the valve core tool and spare valve cores are stored securely.
Do not lubricate the gauge mechanism.

7. Troubleshooting

Problem	Possible Cause	Solution
Air leakage from connections	Loose fittings, insufficient thread seal tape, damaged O-rings.	Tighten all connections. Reapply thread seal tape if necessary. Inspect and replace O-rings if damaged.
Inaccurate pressure readings	Gauge malfunction, debris in the valve stem, extreme temperatures.	Ensure the chuck is fully seated on the valve stem. Check against another known accurate gauge. Allow the unit to acclimate to ambient temperature.
Air not flowing into tire	Air compressor off, low compressor pressure, clogged chuck, faulty valve stem.	Verify air compressor operation and pressure. Check for obstructions in the chuck. Inspect tire valve stem for damage.
