WARNING
Burn Hazard
Oil in the swing pump may be extremely hot. Allow the
hydraulic oil to cool before replacing the swing filter.
CAUTION
Avoid Hydraulic System Damage
Original Equipment Manufacturers’ filter elements—
available from Manitowoc—must be used on this crane.
Substituting with any other brand or type filter element is
not allowed.
Filter elements made by other manufacturers may
collapse under pressure. This action will allow unfiltered
oil to be drawn into hydraulic system—pumps, motors,
and valves can be destroyed.
Manitowoc 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 crane without filter elements installed.
