Adjusting the Model 505.60 Hydraulic Pressure
The output pressure can be adjusted from a low pressure value of 1 MPa (145
psi) to the maximum setting of 21 MPa (3000 psi). If you have a special testing
requirement, you can reduce the HPU output pressure.
Control Locations (505.69/90 shown)
Perform the following procedure to adjust the output pressure. Perform this
procedure on one pump at a time.
The pump and motor are designed to operate below a specified pressure.
Setting the hydraulic pressure above 21 MPa (3000 psi) can damage the
pump and its motor
Do not adjust the output pressure higher than 21 MPa (3000 psi).
