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.
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 89.
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.
