8. Increase the engine speed to 1,500 RPM.
NOTE: Do not leave the valve fully closed for more than 5 seconds, or the pump could be damaged internally.
9. Close the gauge valve fully, and read the pressure.

   Specification:  The pump pressure with the valve closed should be between 8,330-8,820 kPa (1,208-1,279 psi).
