Releasing the residual pressure of hydraulic system
Make sure that there isn't pressure in the hydraulic system that could cause danger during service operations.
DANGER
Hydraulic energy stored in the hoses and other hydraulic components can cause
ejection of hydraulic oil and movements of the hydraulic cylinders or motors. To
release the pressure in hydraulic system:
1.
Lower the boom down completely and place attachment firmly on the ground
2.
Switch off the loader
3.
Move all control levers, including the control lever of the telescopic boom and
auxiliary hydraulics, to extreme end positions a couple of times
Remember that the boom or attachment can move when releasing the pressure.
Move the levers until all movements have stopped.
Extra auxiliary hydraulics coupling
The extra hydraulics coupling is a double-acting hydraulic with two fittings. A pair of standard type hydraulic quick
couplings are located at the front of the loader, just below the multiconnector.
Before you connect or disconnect standard couplings,
relieve hydraulic pressure as described on page 66.
To connect and disconnect the standard couplings,
move the collar at the end of the female fitting
Note that the protective caps on the loader and the
attachment can be fastened to each other during
operation to reduce the accumulation of dirt.
When disconnecting the standard quick couplings a
small amount of oil may drip from the couplings. Wear
protective gloves and have some cloth at hand to keep
the equipment clean.
For more information about the possibility to fit an extra hydraulics coupling see page 48.
To use the extra hydraulics coupling:
1.
Select the extra auxiliary hydraulics outlet:
Switch the selection switch of the hydraulic outlet to position
2
. The switch is located on
the control panel on the right side from the driver's seat
2.
Use the normal auxiliary hydraulics control lever to control the extra outlet, or use the
buttons of the 6-function joystick
3.
When you want to use the multiconnector outlet again, switch the control switch back to
position 1
The quick couplings can be coupled in a way that reverses the function of the control lever. Test the operation
of the attachment after each time it is coupled to the loader.
Keep the couplings clean and use their protective covers.
You can operate either the hydraulic function connected to the standard multiconnector, or the function that is
connected to the extra outlet. Simultaneous use is not possible.
