Activating the optional hydraulics
Activating the optional hydraulics using the control lever
Place the optional hydraulic control in neutral when the system is not required. This is necessary to avoid overheating the hydraulic system and improve fuel economy.
Clean the quick connecting fittings carefully before connecting the optional hydraulic system fittings together. This will avoid introducing contaminants into the system that can cause damage to the hydraulic components. Keep connections covered when not in use.
You can activate the loader lift arms hydraulic connections
(Fig. 37) using the control lever for the optional hydraulics item Z (Fig. 36).
•
Move the control lever for the optional hydraulics to the left (L):
– The left-hand connection is for the pressure side, the right-hand is for the return line.
•
Move the control lever for the optional hydraulics to the right (R):
– The right-hand connection is for the pressure side, the left-hand is for the return line.

Detent mechanism for the optional hydraulics
NOTICE
Overheated hydraulic oil can damage the machine.
Make sure that the control lever for the optional hydraulics is always in »zero position« when the detent mechanism is not required.
Depressurized return line (Optional equipment)
Fig. 38
Depressurized return line
This function allows you to operate the optional hydraulic connections in continuous use. This function is necessary for certain attachments powered by a hydraulic motor that necessitates continuous use (e.g. broom). Then you do not have to constantly hold the control lever for the optional hydraulics.
•
Move the control lever for the optional hydraulics to the left past normal operation position:
– The lever will be locked, providing continuous hydraulic pressure and flow.
For some attachments, a depressurized return line is required. The connection for the depressurized return line is located on the front left of the load arm (Fig. 38). The connection is designed in such a way that it is not possible to confuse it with the normal connections for the optional hydraulics.

If the detent mechanism of the optional control lever is engaged, it is not possible to activate the optional hydraulics with the button.
You can activate the hydraulic connections on the loader lift arms (Fig. 37) using the buttons for the optional hydraulics
Item 1 and Item 2 (Fig. 39).
•
Activate the button for optional hydraulics Item 1:
– The left-hand connection is for the pressure side, the right-hand is for the return line.
•
Activate the button for optional hydraulics Item 2:
– The right-hand connection is for the pressure side, the left-hand is for the return line.
