8 – Connecting and disconnecting the hydraulic hoses
On 400-700 series loaders hydraulic hoses are connected using the multiconnector system. If you
have an Avant 300-700 series loader with the conventional quick couplers and wish to change to the
multiconnector system, contact your Avant dealer or service point for instructions or installation
services. On 200-series loaders the hoses are always connected with quick couplings.
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 (see point 1 of paragraph 5 on
page 12).
Use safety gloves and glasses.
NOTICE: keep all couplings 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 multiconnector onto its holder.
8.1 Connecting the multiconnector system
(Fig. 16)
1. Align the pins of the attachment connector
with corresponding holes of the loader
connector. The multiconnector will not
connect if the attachment connector is
upside down.
2.
C
onnect and lock the multiconnector 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.
