Start the engine, and monitor both pressure gauges:
1) As the pressure indicated on the VMAC test tool gauge reaches 150 psi,
the gauge connected to the 1/4 in PTFE tube should indicate 150 psi. If
the pressure on the gauge connected to the 1/4 in PTFE tube does not
increase, confirm the manual unloader valve has not been adjusted. If the
unloader valve has not been adjusted the discharge valve needs to be
replaced.
2) As the pressure indicated on the PTFE Test Tool gauge connected to the
1/4 in PTFE tube reaches 150 psi, the throttle actuator rod should move
to the right and the engine rpm should decrease. If the throttle actuator
rod does not move, diagnose or replace the throttle actuator.
3) When the system pressure indicated on the VMAC test tool reaches 150
psi, the pressure indicated on the gauge connected to the 1/4 in PTFE
should hold steady at 150 psi. If the pressure does not hold, check for air
leaks or a defective throttle actuator.
4) Slowly open the test tool ball valve. The pressure on both gauges should
drop at approximately the same rate until pressure at the discharge valve
reaches 120 psi. Once the discharge valve pressure drops to 120 psi, the
discharge valve will close and the PTFE test tool gauge will indicate 0 psi.
If the pressures do not drop at the same rate, the discharge valve may be
plugged.
