INTRODUCTION
General
Preventive maintenance at regular intervals is necessary to
keep your machine in good condition as long as possible.
Adjust the maintenance schedule to your operation,
according to type of work, size of loads, temperature
conditions and frequency of machine use.
The intervals in the Maintenance Schedule are average
operating conditions and must be understood as the
MINIMUM maintenance necessary for the machine. Shorten
these intervals if the machine is operated in conditions that
are below average (for example – in dust, in high or low
temperatures, with heavy loads or frequent starting and
stopping).
Use the hour meter to make sure that all necessary
maintenance is done according to schedule.
ENVIRONMENTAL PROTECTION
Dispose of waste properly! Improperly disposing of waste
can threaten the environment.
Potentially harmful waste used in Manitowoc cranes includes
— but is not limited to — oil, fuel, grease, coolant, air
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.
