temperature.
3. Operate the air compressor system until the oil is warm.
4. Open the ball valve on the test tool and observe the engine
tachometer.
Make sure that there are no restrictions to air flow. If the
system cannot produce maximum flow from the tank,
there will be no change in RPM when you turn the
adjusting screw.
5. Turn the maximum RPM adjustment screw clockwise to increase
engine speed and counterclockwise to decrease maximum
engine speed. Count the turns in case you have to start over.
