5 Operation
Additional control circuit of proportional controls (option)
Plug couplings with hydraulic hoses are installed on the loader unit of the
wheel loader for the operation of hydraulic attachments with additional
hydraulic functions (for example high-tilt bucket with clamp).
The additional control circuit is operated electronically (proportional
controls) by means of scroll wheel 86 on the joystick and a solenoid valve
on the controller.
Important information on the additional control circuit (propor-
tional controls)
Connecting the flexible lines incorrectly results in incorrect
operation and/or uncontrolled movements of the attachment!
Failure to observe this can cause serious injury or death.
► Ensure that the hose pipes are connected correctly.
► Follow the instructions in the Operator’s Manual of the attachment
manufacturer.
► Check the response direction of the control elements before using the
attachment.
In order to avoid leaks on the plug couplings and dirt in the hydraulic oil,
► carefully clean the plug couplings and flexible lines before connecting
them.
Damage hazard to the machine and/or the attachment!
► Check the flow rate of the attachment before putting it into operation.
► Flow rate indications and consumer pressure on the plug couplings of
the machine – see chapter 9 “Usable consumer pressure at additional
control circuit (option)” on page 9-11.
Always operate attachments with only one hydraulic circuit on the plug
couplings of the 3rd control circuit.
