5 Operation
Releasing the pressure at the plug couplings
The hydraulic system of the machine is still pressurized even when the
engine is not running! The hydraulic plug couplings can be released,
however they cannot be re-attached because the pressure in the hydraulic
lines has not been released.
Release the pressure in the system sections before installing or removing
an attachment! There are two possibilities for this:
• Standard: Via the rocker switch 82 on the joystick,
• Option: Via the touch button E on the inside of the loader unit.
3rd control circuit – releasing the pressure with the rocker
switch on the joystick (standard)
1. Apply the parking brake.
2. If the "work hydraulics" lock for long-haul travel is activated, slide the
lock in the toggle switch 89 downward and press the toggle switch into
the position A.
3. Stop the diesel engine, but do not switch off ignition.
4. Press and hold push button 50.
5. At the same time, press and hold the rocker switch 82 on the joystick in
the position C and D for about 5 seconds each.
➥ Pressure in hydraulic lines is released.
6. The plug couplings can now be changed over
– see “Hydraulic control circuits/plug couplings (overview)” on
page 5-37.
