How to Use

Step 1: Determine the target tire pressure for your terrain.
Step 2: With the lock ring and adjusting cap wound down, thread the deflator onto the valve stem. Ensure threads are clean and in good condition.
Step 3: Loosen the adjusting knob until you hear air release, then immediately tighten the cap to the position where airflow stops.
Step 4: Tighten the lock ring slightly until airflow ceases. The deflator will now automatically release air until the preset pressure is reached.
Note: When tire pressure and deflator setting fall below 8 PSI, a manual start operation may be required.
