ENVIRONMENTAL PROTECTION
Dispose of waste properly! Improperly disposing of waste
can threaten the environment.
Potentially harmful waste used in Manitowoc cranes includes

conditioning refrigerant, filters, batteries, and cloths which
have come into contact with these environmentally harmful
substances.
Handle and dispose of waste according to local, state, and
federal environmental regulations.
When filling and draining crane components, observe the
following:
• Do not pour waste fluids onto the ground, down any
drain, or into any source of water.
• Always drain waste fluids into leak proof containers that
are clearly marked with what they contain.
• Always fill or add fluids with a funnel or a filling pump.
Immediately clean up any spills.
MAINTENANCE RECORDS
Dated records must be kept for inspection of critical
components such as, brakes, crane hooks, wire ropes,
