Connecting and disconnecting hydraulic hoses
On Avant loaders the hydraulic hoses are connected using the multi connector system. If you have an Avant
300-700 series loader with the conventional quick couplers and wish to change to the multi connector system,
contact your Avant dealer or service point for instructions or installation services.
WARNING
Risk of movement of the attachment and ejection of hydraulic oil - Never connect
or disconnect quick couplings or other hydraulic components while the control
lever of the auxiliary hydraulics control lever is locked on or if the system is
pressurized.
Connecting or disconnecting the hydraulic couplings while the system is
pressurized may lead to unintended movements of the attachment, or ejection of high-
pressure fluid, which can cause serious injuries or burns. Follow safe stopping procedure
before disconnecting hydraulics.
Keep all fittings as clean as possible; use the protective caps on both the attachment and
the loader. Dirt, ice, etc. may make using the fittings significantly more difficult. Never
leave the hoses hanging on the ground; place the couplings onto the holder on the
attachment.
Connecting the multi connector system:
1.
Align the pins of the attachment connector with corresponding
holes of the loader connector. The multi connector will not
connect if the attachment connector is upside down.
2.
Connect and lock the multi connector by turning the lever towards
the loader.
The lever should move easily all the way to its locking position. If the lever does not slide smoothly, check the
alignment and position of the connector and clean the connectors. Also shut down the loader and release the
residual hydraulic pressure.
To disconnect the multi connector system:
Before disconnecting put the attachment down on a solid and even
surface.
1.
Switch off the auxiliary hydraulics of the loader.
2.
While pushing unlock button, turn the lever to disconnect the
connector.
3.
After ending operation put the multi connector on its holder on the
attachment.
Disconnecting hydraulic hoses:
Before disconnecting the fittings, lower the attachment to safe position on solid and level surface. Turn the
control lever of the auxiliary hydraulics to its neutral position.
When uncoupling the attachment, always disconnect the hydraulic couplings before
unlocking the quick attach plate, to prevent hose damage and any oil spills. Reinstall the
protective caps on the fittings to prevent impurities from entering the hydraulic system.
