Setting ranges for Single-acting auxiliary high-flow hydraulic circuit
The maximum flow rate for the Single-acting auxiliary high-flow hydraulic circuit can be selected within the following
range:
Level
1
2
3
4
5
6
7
8
9
10
The maximum flow rate for Breaker 1 combination is set from factory:
Single-acting circuit
The message CHECK FLOW RATE appears at the bottom of the setting tab if a value above Level 10 is selected.
If attachment operation is anyway started with this setting, the message CHECK FLOW RATE will appear on the
top of the display, and a warning buzzer will sound.
Stop attachment operation, and make sure to select a value of maximum flow rate that does not exceed Level 10.
NOTICE: the working pressure can be set from the instrument cluster only for the Multi-function auxiliary high-flow
hydraulic circuit. For the Single-acting circuit and for the Double-acting circuit the working pressure shall be set man-
ually.
NOTICE: the working pressure of the Single-acting auxiliary high-flow hydraulic circuit shall be set manually by the
relief valve located behind the boom foot. The factory setting of the relief valve located behind the boom foot is
17.65 MPa (2560 psi). The maximum setting of the relief valve is 21 MPa (3046 psi).
