PREVENTIVE MAINTENANCE CHECKLIST
3000 through 4100W
GENERAL
This folio contains a checklist of the inspections, main-
tenance, and service parts replacements required by
this machine and the
recommended interval
at which
each check should be made. Performing each check at
the recommended interval will help maintain the safety,
dependability, and productivity designed into this
machine.
NOTE
Optional items that may not be on your crane are
indicated by this symbol (1).
Maintain engine(s), air compressor(s), and light
plant according to the manufacturers' instructions.
MAINTENANCE INTERVALS
The letters in the right columns of the checklists corres-
pond to the following intervals.
Peform the checks at the hourly interval or the calendar
interval, whichever comes first.
A -- Every 8 to 10 Hours or Daily
B -- Every 40 to 50 Hours or Weekly
C -- Every 200 Hours or Monthly
D -- Every 1000 Hours or 3 Months
E -- Every 2000 Hours or 6 Months
The above maintenance intervals are based on average
operating conditions, and should be used only as a
guide until adequate experience is obtained to establish
intervals which meet the operating conditions of your
machine (frequency and duration of operation, loading
involved, dusty or corrosive atmosphere, outside air
temperature, etc.).
Any change in the recommended intervals, either
increasing or decreasing, should be preceded with a
complete analysis of how the machine is performing.
Carefully study previous maintenance checklists and
service records before making any changes; an oil analy-
sis of each fluid used in the machine should be the major
factor used in determining oil-change intervals.
USING MAINTENANCE CHECKLIST
This checklist covers 200 hours of operation (approxi-
mately one month working one shift a day); therefore, a
new checklist must be started each time 200 hours of
operation or one month has been completed.
