MOUNTING THE CHIPPER ON AVANT LOADER
Coupling the attachment to the loader is quick and easy, but it must be done carefully. The attachment is xed
to the loader boom by using the quick attach plate and the counterpart on the attachment. I If the attachment
is not locked to the loader, it may detach from the loader and cause hazardous situations. In the worst case, the
attachment may slide onto the driver along a raised boom. For this reason, the attachment must not be raised
over one metre under any circumstance if it has not been locked.To prevent hazardous situations, always follow
the attachment coupling instructions provided in the following pages. Also remember the safety instructions
and additional infromation shown in the operator’s manual of the loader. The attachment is mounted to the
loader as follows:
Make sure that an unlocked attachment will not move or fall over. Mount the
attachment only on level surface.
WARNING!
!
1. Step:
• Lift the quick attach plate locking pin / locking pins up and turn them backwards into the slot so that they
are locked in the upper position.
• If your loader is equipped with a hydraulic attachment locking system, see additional instructions about
the use of the locking system from the relevant manuals.
• Ensure that the hydraulic hoses or electric cables are not in the way during installation

CONNECTING AN DISCONNECTING HYDRAULIC HOSES
On 200-700 series loaders hydraulic hoses are connected using the multiconnector system. If you want to chan-
ge the type of the hydraulic couplings, contact your Avant dealer or service point for instructions or installation
services. On old 200-series loaders only conventional quick couplings are available.
Never connect or disconnect quick couplings or other hydraulic components while the
system is under pressure or if the control lever of the auxiliary hydraulics control lever
is locked on. Connecting or disconnecting the hydraulic couplings while the system
is pressurized may lead to unintended movements of the attachment, or ejection of
highpressure uid, which can cause serious injuries or burns. Follow safe stopping pro-
cedure before disconnecting the hydraulic hoses.
Keep the ttings as clean as possible; use the protective caps for the quick couplings on
both the attachment and the loader. Dirt, ice, etc. may make using the ttings signi-
cantly more dicult. Never leave the hoses hanging on the ground; place them on the
holder on the attachment.
An attachment that has not been completely locked to the loader may fall on the boom
or operator, or under the loader during driving, and cause serious injuries or loss of
control of the loader. Before moving or lifting the attachment, make sure that the
locking pins are in the lower position and come through the fasteners on both sides.
Never move or lift an attachment that has not been locked.
WARNING!
!
200-700 series
loaders:
Old 200 series
loaders:
Excessive tilting or lifting of an unlocked attachment increases the risk of tipping the
attachment over. Do not use the automatic locking of the locking pins when the at-
tachment is lifted more than one meter from the ground. If the locking pins do not
return to the normal position when tilting, do not tilt or raise the attachment any more.
Lower the attachment on the ground and secure the locking manually.

CONNECTING THE MULTICONNECTOR SYSTEM:
Alignthepinsoftheattachmentconnectorwithcorrespondingholesoftheloaderconnector.Themulticonnector
will not connect if the attachment connector is upside down. Connect 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. To disconnect the multi connector system switch o the auxiliary hydraulics of the
loader and unlock the multiconnector. To unlock the multiconnector, push and hold the unlock button on the
side of the multiconnector, then turn the lever to disconnect the connector.
USING CONVENTIONAL QUICK COUPLINGS
(alternative couplings for some loader models):
Before connecting or disconnecting the standard quick couplings, the residual pressure must be released as
shown below. The conventional quick couplings will not connect, if there is pressure in the hydraulic system.
To connect and disconnect the standard couplings, move the
collar at the end of the female tting. The hoses should be
connected so that the tting equipped with a coloured cap
is connected to the corresponding tting of the loader 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.
Make sure that all three quick coupling ttings are properly connected, otherwise the
hydraulic motor of the attachment may get damaged.
CAUTION!
