Connecting Auxiliary Hydraulic Couplings
Note:
With the engine off, key in the ON position and the restraint bar down, the
auxiliary hydraulic control can be moved to relieve any pressure in the hydraulic
system. Because the auxiliary hydraulics system is controlled using pilot pressure
stored in an accumulator, the engine must have been run recently.
Standard-Flow Auxiliary Hydraulics
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.
High-Flow Auxiliary Hydraulics (optional)
Couplers are located on the right 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.
Only connect high-flow attachment couplers
to the high-flow auxiliary couplers.
Removing Attachments
1. Tilt the hitch back until the attachment is off the ground.
2. Exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE
(page 6).
3. With the engine off, leave the operator’s compartment and disconnect the
auxiliary hydraulic hoses.
4.
Manual hitch:
Rotate the latch lever to the right when viewed from the front
to fully retract the latch pins.
Power hitch:
Start the engine, press the top edge of Power-A-Tach switch on
the right instrument panel to retract the hitch pins to unlock the hitch and fully
retract the latch pins. Release the switch.
5. Start the engine (if it is not already on) and be sure that the lift arm is fully
lowered and in contact with the loader frame.
6. Tilt the hitch forward and slowly back the loader away until the attachment is
free from the loader.
Self-Leveling (optional)
The self-leveling feature is intended to automatically keep the attachment level
while the lift arm is being raised. Self-leveling operates only when the lift arm is
raised; when the lift arm is lowered, self-leveling is not activated.
