Connecting Auxiliary Hydraulic Couplings
Important:
Connect hydraulically-powered attachment hoses to the auxiliary circuits
after the attachment is secured to the hitch.
Disconnect hydraulically-powered attachment hoses from the auxiliary circuits before
removing the attachment from the hitch.
1. Empty the attachment and lower it to the ground.
2. Shut off the engine. With the ignition on,
but the engine off, move the auxiliary
hydraulics control rocker switch (F, Figure
65) on the right T-bar, joystick or hand
control back and forth to relieve pressure
in the auxiliary hydraulics circuit.
3. Turn off the ignition. Remove the ignition
key and take it with you.
4. Raise the safety bars/arm rests and exit the
machine using the hand holds.
5. Clean the hydraulic connections on the
hoses and the connections.
6. Relieve any residual pressure remaining in the auxiliary hydraulics circuit by pushing
the attachment coupler firmly into the auxiliary coupler (Figure 66).
Route the
hydraulic hoses
so they do not get pinched when the
attachment is tilted forward and
back. Damaged or burst hydraulic
hoses could result.
7. Continue to push the hose connections
firmly onto the auxiliary hydraulic
connections until they snap into place.
Note:
Pressure build-up caused by heat in
hydraulic attachments left in direct sunlight
can make it difficult to connect the quick-
couplers to the fittings on the attachment.
Note:
The auxiliary hydraulic couplers are located on the left lift arm. When the auxiliary
control switch is activated in either direction, the inside and outside couplers can be
“pressure” or “return”, depending on which direction the switch is activated. The smaller
center coupler is for the case drain.
Important:
Always check hydraulic function of the attachment before use, to make sure
the hydraulic hoses have not been installed in reverse.
