TROUBLESHOOTING
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 your-
self if you have the RIGHT TOOLS, IF you have the PROP-
ER 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 equip-
ment and service knowledge to pin-point the problem in min-
utes 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 log-
ical TROUBLE SHOOTING PROCEDURE. Don’t simply
replace parts until the trouble is found.
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 judg-
ment 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 fail-
ure. 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 down-
time. 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, adjust- ments 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.
