Model 505G2.07/.11 SilentFlo™ HPU 46
Adjusting the Hydraulic Pressure
Perform the procedure for adjusting the auto-cooling level if the adjusted output
pressure is between 14 MPa (2000 psi) and 21 MPa (3000 psi) and the HPU will
be operated in high pressure mode for an extended period of time (longer than 10
minutes).
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).
