Locking The Hydraulic Coupler To The Attachment-If Equipped - Worldwide Construction And Forestry Division 380GLC Operator's Manual

Locking the Hydraulic Coupler to the Attachment—If Equipped
Front Hook on Hydraulic Coupler
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.
