Operating instructions
Coupling the hydraulic hoses of the attachment
Hydraulic hoses of the attachment are equipped with the multi connector system, which connects all hoses at the
same time.
Coupling the multi connector
Align the pins of the attachment connector with correspondig holes of
the loader connector. Connecting is not possible if the multi connector
for some reason is mounted in a wrong way on the attachment hoses.
Connect and lock the multiconnector by turning the lever towards the
loader.
The lever should move easily all the way to locking poisition. If the lever
doesn’t move easily, check alignment and position of the attachment and
loader side connectors and clean the connectors. Stop the engine and
release pressure in auxiliary hydraulics line.
Disconnecting the multi connector
• Before disconnecting put the attachment down on a solid and even
surface. Switch off auxiliary hydraulics. Disconnect attachment hoses by
pressing on the red button on the multiconnector and simultaneously
turn the lever away from the machine.
• After ending operation put the multi connector on its “parking” on the
attachment.
Make sure that the attachment is properly connected on the
attachment coupling plate. An attachment that comes loose may tip
over or fall on the loader, causing personal injuries.
Do not try to lock the locking pins by using the brackets on the
boom when the attachment is lifted over one metre from the
ground. Lock the locking pins by hand and make sure that both pins
lock properly down in the holes of the attachment.
Always read also the additional instructions for coupling and using
of the attachment in the Operators Manual of the attachment.
Make sure that the attachment is locked to the loader
Releasing the pressure of hydraulic system
Make sure that there isn’t pressure in the hydraulic system that could cause danger during service operations.
In order to release the pressure in hydraulic system stop first the engine and lower the boom down completely.
Move all control levers, including control lever of 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.
When fitting an attachment, make sure that the hydraulic hoses are not overstretched and are not in a
position where they can be trapped during the operation of the machine and attachment.
