Auxiliary low-flow hydraulic circuit
The machine can be equipped with an additional low-flow auxiliary hydraulic circuit to operate attachments featuring
secondary hydraulic actuation for positioning, such as rotating grabs or tiltable buckets.
NOTE: the maximum flow rate of the auxiliary low-flow hydraulic circuit using the SP work mode is 55 L/min (14.5 US
gpm). The maximum working pressure of the auxiliary low-flow hydraulic circuit is 20.6 MPa (2988 psi).
NOTE: an additional drainage line (D) is located on the left side of the arm. The drainage line (D) is intended to allow
external drainage from an hydraulic motor.
NOTICE: always keep each connecting hose on the same side of the arm. Never cross-over the connecting hoses
between the two sides of the arm.
Use the proportional switch located on the left-hand con-
trol lever to operate the grab rotation or the bucket tilt with
a variable power.
Make sure that the control pattern of the positioning actu-
ation is as intended. Slide up and down the proportional
switch and confirm the control directions (e.g. left/right).
NOTICE: if control directions for the positioning actuation
are not as intended, check for an alternative set up of the
hydraulic connections between the attachment and the
machine.
NOTICE: if not using any hydraulic attachment, do not
operate controls for auxiliary hydraulic circuits.
