Operation
Auxiliary hydraulics pedal cover
Always lower the cover for locking the auxiliary hydraulics if it is not in use, in
order to avoid pressing auxiliary hydraulics pedal 2 inadvertently –
Accident hazard!
☞ Always cover auxiliary hydraulics pedal 2 if it is not in use
Raise cover A to use auxiliary hydraulics pedal 2.
3.16 Releasing the pressure on the quick couplers on the loader unit
The hydraulic system of the machine is still pressurized even when the engine is
not running! The hydraulic quick couplers can be released, however they cannot
be re-attached because the pressure in the hydraulic lines has not been released.
Therefore:
• Release the pressure in the sections of the system and hydraulic lines that are to
be opened before starting setup or repair work, for example fitting/removing an
attachment!
Release the pressure as follows:
☞ Apply the parking brake
☞ Stop the engine
☞ Do not disengage the starter
☞ Switch on High Flow (option)
☞ Press the pedal for the auxiliary hydraulics to the left and right for about 5 – 8 seconds
☞ Disengage the starter and remove the starting key
3.17 Couplings
Connect and disconnect the couplings as follows:
Removing the coupling:
☞ Park the machine on level and horizontal ground
☞ Lower the loader unit completely and set the attachment to the ground
☞ Stop the engine, starter in position 1 (safety bar closed)
☞ ISO controls: release the pressure in the pressure lines by moving the control lever
on the right in all directions
☞ H controls: release the pressure in the pressure lines by moving the left and right
control levers to the left and right
☞ Raise the safety bar
☞ Unfastening the seat belt
☞ Turn lock sleeve B toward lock ball A
☞ Pull lock sleeve B upward
☞ The coupling opens
Connecting the coupling:
☞ Connect the coupling onto the loader unit connection ensuring that it is straight
☞ Wait until you hear a hissing sound of the connection
☞ Fully connect the coupling on the connection
☞ Turn back the lock again (away from lock ball A)
