TROUBLESHOOTING
The majority of operating problems that occur with a system can be traced to improper adjustments or delayed service. A consistently applied preven- tive maintenance program, as outlined in the maintenance section of this manuel, will prevent many problems. The following chart is designed to help you locate a problem by suggesting probable causes and recommended solu- tion(s).
The suggested remedies should be applied with care. Make certain that the source of a problem is not located someplace other than where the problem exists. A thorough understanding of the system is a must if operating prob-
lems are to be converted satisfactorily. A good rule to follow in locating trou- ble is to never make more than one adjustment at a time, then locate trouble by a process of elimination. Remember the cause is usually simple, rather than mysterious or complicated. Separate troubleshooting guides are included in engine and tractor owner’s manuals.
Operators handling the same equipment every day soon develop a sense of impending trouble when abnormal operation occurs. Immediate attention to these danger signals can prevent major failures, ensure dependable operation and increase the life of equipment.
