Burn Hazard!
The oil in the hydraulic tank may be under pressure and
extremely hot. Hot oil can escape when servicing
components.

CAUTION
Avoid Hydraulic System Damage!
Original Equipment Manufacturers’ filter elements,
available from the Manitowoc Crane Care Lattice Team,
must be used on this crane. Substituting with any other
brand or type of filter element is not allowed.
Non-OEM filter elements may collapse under pressure.
This will allow unfiltered oil to be drawn into the hydraulic
system. Pumps, motors, and valves can be destroyed.
Manitowoc Cranes will reject warranty claims for
damaged hydraulic components if proper hydraulic filter
elements are not used.
• Do not attempt to clean or reuse elements.
• Do not operate the crane without filter elements
installed.
