Checking the vibration pump
• Close the high pressure ports on the vibration pump with plugs
• Check the vibration pressures, see Fig. V2
If the pressure values are now reached whereas they were not reached while the vibration motor was
connected, the vibration motor must be faulty. If the high pressure values are not reached, the fault must
be in the pump.
