General Procedure
1. KNOW THE SYSTEM Study this manual and learn what makes the machine “tick”,
how it should behave, sound and smell.
2. OPERATE THE MACHINE Test operate all machine functions. Note all abnormal
sounds, odors and movements. Always proceed in the most logical order to determine
the cause.
3. INSPECT THE MACHINE Look for leaks, listen for the source of abnormal sounds,
detect the origin of unusual odors. Check the condition of the oil and filters.
4. LIST THE POSSIBLE CAUSES Use your best judgment in listing all possible causes of
the failure.
5. REACH A CONCLUSION Review your list of possible causes and decide which are the
most likely to cause the failure. Consider the most obvious first.
6. TEST YOUR CONCLUSION Test your conclusions, in order of obviousness, until the
source of the failure is found. The machine can then be repaired at minimal cost and
downtime. Make the repair. Recheck to ensure that nothing has been overlooked,
functionally test the repaired part in the system.
7. REVIEW MAINTENANCE PROCEDURES Prevent recurrences of all premature failures
by regularly checking the filters, temperature, adjustments and lubrication. Make daily
inspections.
NOTE: Your safety and that of others is always the number one consideration when
working around cranes. Safety is a matter of thoroughly understanding the job to be
done and the application of good common sense. It is not just a matter of “do’s”
and “don’ts”. Stay clear of all moving parts.
