Auxiliary hydraulic circuits

Consult your CASE CONSTRUCTION Dealer to select the optional accessory compatible with your machine and to
correctly adjust the flow required for its use.
NOTICE: To prevent failure or damage to the tool, make sure that you select the correct circuit configuration and flow
rate for the tool.
Auxiliary high-flow hydraulic circuit
Your machine can be equipped with one of the two following types of auxiliary high-flow hydraulic circuit. One type
of circuit is specifically intended for usage with single acting hydraulic attachments, such as hydraulic breakers. The
second type is intended for usage with either single-acting hydraulic attachments, such as hydraulic breakers, or
double-acting hydraulic attachments, such as crushers.
Usage of a hydraulic breaker
1. Operate the controls of boom, arm and bucket in order
to install the hydraulic breaker to the bucket linkage at
the top of the arm.
2. Stop the engine. Set the starter key to ON position,
and press the right-hand auxiliary pedal to release
pressure inside the auxiliary high-flow hydraulic circuit.
3. Close the feed valves at the top of the arm. Install
the connecting hoses between the attachment and the
feed valves. Then reopen the feed valves.
4. Start the engine. Press and hold the attachment se-
lector button (1) for 1 s to get directly to the dedicated
tab for operational settings of the auxiliary high-flow
hydraulic circuit.
5. Select BREAKER as attachment type, and set the
proper flow rate of the circuit.
NOTICE: The working pressure of the single-acting
auxiliary high-flow hydraulic circuit shall be set man-
ually by the port relief valve on the relevant section of
the control valve.
NOTICE: The working pressure of the multifunction
auxiliary high-flow hydraulic circuit shall be set man-
ually by the relief valve located behind the boom foot.
6. Press the menu button (2) to confirm the selection.
7. Resume the operating mode of the display. An icon
on the top-right of the display indicates the type of
attachment (breaker) and the storing number (1 to 5)
of the flow rate currently in use.
The pump setting (single) and the value of maximum
flow rate are shown at the top-center of the display.
NOTICE: to prevent failure or damage to the tool,
make sure that you select the correct circuit configu-
ration and flow rate and pressure for the tool.
