2. Setup

The Milton S-986 Tire Pressure Gauge requires minimal setup. It is ready for use directly out of the packaging.

Initial Inspection:

  • Inspect the gauge for any visible damage from shipping.
  • Ensure the indicator bar moves freely within the brass tube.
  • Confirm both ends of the dual head chuck are clear of obstructions.

3. Operating Instructions

For accurate tire pressure readings, ensure tires are cold (driven less than one mile or stationary for at least three hours).

Checking Tire Pressure:

  1. Remove Valve Cap: Unscrew the valve stem cap from the tire.
  2. Position Gauge: Select the appropriate head on the dual-head chuck (straight or angled, depending on valve stem access). Firmly press the gauge straight onto the tire valve stem. You should hear a brief hiss of air as the gauge seats.
  3. Read Pressure: The internal indicator bar will extend from the gauge, displaying the tire pressure. Read the measurement at the end of the extended bar.
  4. Remove Gauge: Pull the gauge straight off the valve stem. The indicator bar will remain extended, holding the reading until manually reset.
  5. Reset Gauge: Push the indicator bar back into the gauge body to reset it for the next reading.
  6. Replace Valve Cap: Screw the valve stem cap back onto the tire to prevent dirt and moisture from entering the valve.

Understanding the Dual Head Chuck:

The S-986 features a dual-head chuck with a straight foot. This design allows for easy access to valve stems, especially on inner dual wheels where space is limited. The straight end is ideal for direct access, while the angled end can be used for valve stems that are slightly recessed or at an awkward angle.

4. Maintenance

Proper maintenance ensures the longevity and accuracy of your Milton S-986 Tire Pressure Gauge.

Cleaning:

  • Wipe the exterior of the gauge with a clean, dry cloth after each use to remove dirt and grime.
  • Avoid using harsh chemicals or abrasive cleaners, as these can damage the finish or internal components.

Storage:

  • Store the gauge in a clean, dry environment, away from extreme temperatures and direct sunlight.
  • Protect the chuck ends from impact or bending, which could affect their sealing ability.

5. Troubleshooting

ProblemPossible CauseSolution
Inaccurate ReadingGauge not fully seated on valve stem; gauge is dirty or damaged; tire not cold.Ensure firm, straight connection to valve stem. Clean gauge. Check tire pressure when tires are cold. If issues persist, gauge may need replacement.
Air Leaks During MeasurementImproper seating of the chuck on the valve stem; worn valve stem; damaged chuck.Apply firm, even pressure when attaching the gauge. Inspect valve stem for damage. Check chuck for debris or damage.
Indicator Bar SticksDirt or debris inside the tube; bent indicator bar.Gently try to free the bar. Avoid forcing it. If persistent, the gauge may be damaged internally and require replacement.
