Unlocking the Hydraulic Coupler From the
Attachment—If Equipped
CAUTION: Prevent possible injury or death from
unexpected hydraulic coupler movement. Make
sure hydraulic coupler is attached correctly
to attachment. The supplemental lock can be
engaged with the attachment in an incorrect
lock position. A visual check is required each
time the lock operation is performed.
CAUTION: Avoid personal injury. Prevent
injury from hydraulic coupler movement. Keep
bystanders clear of machine.
IMPORTANT: Prevent possible hydraulic coupler
damage from incorrect installation. Attaching
the bucket in a reverse orientation on the
hydraulic coupler is not recommended.
When installed in the reverse orientation,
the bucket or the lift hook interferes with
the arm of the excavator when the bucket is
in full curl position by extending the bucket
cylinder. This is an inherent part of the
design of the original equipment.
Since the hydraulic coupler interacts with
the arm at full curl position to unlock the
supplemental lock, the hydraulic coupler will
NOT operate properly when the bucket is
attached in reverse orientation.
1. Keep attachment close to ground.
NOTE: The hydraulic coupler must be held over relief in
order to unlock the hydraulic coupler cylinder.
2. Rotate hydraulic coupler to full curl position to release
supplemental lock.
NOTE: The safety buzzer located on the hydraulic coupler
control box (3) will sound to alert personnel the
lock/unlock function has been activated.
3. Press UNLOCK button on hydraulic coupler control
box (3). Hold in full curl position for 5 seconds.
4. Slowly uncurl hydraulic coupler. Front hook (1) will
release from pin (2).
Reset Lock Controller
CAUTION: Avoid personal injury. Prevent
injury from hydraulic coupler movement. Keep
bystanders clear of machine.
The safety buzzer will sound if an error occurs with the
hydraulic coupler control box circuit.
1. Lower attachment to ground.
2. Turn key switch to OFF position.
