Easy To Use
1. Assemble Digital Gauge with Hose and Adapter :
There are 2 sets of adapters in the carry case, hose with adapter and universal direct shaft.
Depends on the choice of engine and pressure intake. Pull up the meter jacket for quick connection, insert the high pressure hose, and snap back the brass fitting on the hose.
2. Prepare for testing :
Run the engine for 10 minutes before the test to reach normal operating temperature.
Choose the same size brass adapter compared to the spark plug, 18mm, 14mm, 12mm or 10mm, hand fastening adapter. Dont use a wrench.
3. Accurate reading :
Crank the engine for at least 4 compression strokes or until the pressure reading stops rising to specifications.
Professionally calibrated meters always return a reading at 1% of the exact pressure of your tire and a 0.5 display resolution. Stop guessing.
4. Rapid repeat test :
Built-in pressure release valve allows pressure to be released with a single push button. It is important to repeat tests and record readings to avoid errors.
