NOTICE
The serial number of the crane and applicable attachments (luffing jib) is the only
method your Manitowoc dealer or the Manitowoc Crane Care Lattice Team has of
providing you with correct parts and service information.
The serial number is located on a crane identification plate attached to the operator’s
cab and each attachment. Refer to the Nameplate and Decal Assembly drawing in
Section 2 of this manual for the exact location of the crane identification plate.
Always furnish serial number of crane and its attachments when ordering parts or
discussing service problems with your Manitowoc dealer or the Manitowoc Crane Care
Lattice Team.
To prevent death or serious injury:
• Avoid unsafe operation and maintenance.
Crane and attachments must be operated and maintained by trained and
experienced personnel. Manitowoc is not responsible for qualifying these
personnel.
• Do not operate or work on crane or attachments without first reading and
understanding instructions contained in Operator Information Manual and
Service Manual supplied with crane and applicable attachments.
• Store Operator Information Manual and Service Manual in operator’s cab.
If Operator Information Manual or Service Manual is missing from cab,
contact your Manitowoc dealer for a new one.
