LUBRICATION SYMBOLS
The following symbols are used in the decals on the crane to
identify lubrication points.
GENERAL LUBRICATION
This Lubrication Guide identifies the lubrication points and
intervals for this crane.
The lubrication intervals for OEM (Original Equipment
Manufacturer) parts (engine, light plant, etc.) have been
omitted from this Lubrication Guide. Service OEM parts
according to the original equipment manufacturers’
manuals.
Depending on the options your crane is equipped with, some
lubrication points given in this Lubrication Guide may not
apply to your crane.
LUBRICATION INTERVALS
The intervals listed in this Lubrication Guide are for average
operating conditions based on experience gained by
testing lubricants at the factory and on the recommendations
of lubricant suppliers. Severe operating conditions—
excessively dusty or corrosive atmosphere, unusually high
or low outside temperature, extreme loadings, uncommonly
frequent or long operating cycles—may require shortening
the lubrication intervals. Follow the intervals given in this
Lubrication Guide until adequate experience is obtained to
establish intervals which meet your operating conditions.
Bearings and bushings that are too warm, excessive play in
moving parts, binding in moving parts, excessive or
abnormal wear in gears and chains, and rust accumulation
indicate a lack of lubrication. If these conditions are found
during regular inspection, the lubrication interval for the
faulty parts should be shortened.
Perform an oil analysis at regular intervals of each fluid used
in the crane to determine oil-change intervals. Oil sample kits
are provided in the Parts Box of current production cranes.
It is assumed that the lubrication intervals are cumulative —
daily tasks are performed together with weekly tasks, daily
and weekly tasks are performed together with monthly tasks,
etc.
The lubrication intervals are based calendar time, on engine
hours of operation, or on function hours of operation,
whichever occurs first.
• Engine hours are shown in the Crane Status Bar of the
main display (see the Main Display Manual for
instructions).
• Function hours are shown in the Function Hours Screen
of the main display (see the Main Display Manual for
instructions).
WARNING
Personal Injury Hazard
Personal injury can occur if the following safety
precautions are not taken before and after servicing
machinery.
• Stop the engine and wait until all moving parts have
completely stopped (if necessary, position any grease
fittings on moving parts at the access point and then
stop the engine).
• Attach a WARNING “out-of-order” sign to the engine
start control in the operator’s cab to warn all
personnel that the crane is being serviced.
• Do not operate the crane until all safety guards and
covers have been securely reinstalled and all
maintenance equipment has been removed.

CAUTION
Avoid Machinery Damage
Before lengthening lubrication intervals, check that all
parts are receiving an adequate supply of clean lubricant;
otherwise, parts will be damaged from a lack of lubrica-
tion. Contact your Manitowoc dealer or the Manitowoc
Crane Care Lattice Team for recommendations on length-
ening lubrication intervals.
