General Procedure
As the operator, it is your responsibility to detect any unusual, sounds, odors, or other
signs of abnormal performance that could indicate trouble ahead.
By detecting any problems in their early stages, you can save yourself unnecessary
downtime and your employer a lot of money! Therefore, it is also your responsibility to use
good judgment in detecting failures in quickly and repairing them. If you don’t, one failure
can lead to another.
Before attempting to make an adjustment yourself, ask yourself if you have the RIGHT
TOOLS, IF you have the PROPER TEST EQUIPMENT and IF you can accurately
DIAGNOSE the cause of the problem.
If you can’t answer YES to all three questions, rely on your Distributor Serviceman. He has
the right tools, testing equipment and service knowledge to pin-point the problem in
minutes instead of the hours consumed in hit-or-miss methods. TIME IS MONEY! He will
save it for you.
If you decide to attempt an adjustment yourself, follow a logical TROUBLE SHOOTING
PROCEDURE. Don’t simply replace parts until the trouble is found.
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.
