SECTION 3
PREVENTIVE MAINTENANCE SERVICE
313 Meaning and Importance
Preventive maintenance means making systematic checks and adjustments
at regular intervals to keep equipment operating at top efficiency. It is
not the same as troubleshooting and repair. The purpose of preventive
maintenance is to prevent breakdowns and, therefore, the need for repair.
The purpose of troubleshooting and repair is to locate and correct existing
defects. The importance of preventive maintenance cannot be overemphasized.
Failure or inefficient operation of one piece of equipment may cause the
failure of the entire washer operation. It is vitally important, therefore,
that operators properly maintain their equipment.
Most of the parts of Washer EK1 require routine preventive
maintenance. Because maintenance technique cannot be applied
indiscriminately, definite and specific instructions are needed. Paragraphs
316 through 321 contain specific instructions for the general maintenance
of the equipment and serve as a guide for organizational maintenance
personnel.
315 General Inspection
To insure efficient and troublefree performance of all operating
parts, inspect, lubricate, and check Washer EK1 for cleanliness at regular
intervals. Avoid the use of unauthorized cleaning substitutes and of
improvised implements of inspection and correction.
