Revision 3
I.
Preventive Maintenance Overview
All machine parts wear with use. This wear does not always result in
out-and-out
equipment failure, but rather in a creeping out
of
tolerance that can cause gradual
deterioration
of
results. Preventive maintenance must be performed on a regular basis at the
correct intervals to thwart this degradation.
A conscientiously applied program
of
preventive maintenance is required because it will
result in longer life and enhanced reliability for the equipment.
Preventive maintenance is the systematic care, inspection and servicing
of
equipment
to
maintain it in a serviceable condition and
to
detect and correct early and minor problems
before expensive and time consuming repairs or replacement parts are required.
Preventive
maintenance is generally performed by maintenance personnel.
The desirability
of
preventive maintenance has always been there, but often because
of
a
pressing need for emergency repair work brought on by its very absence, preventive
maintenance has quite often been neglected. This attitude
of
supposedly benign neglect is
changing, partly in response to an ever increasing sophistication and complexity in industrial
equipment.
The proper operation and use
of
equipment contributes
to
preventive maintenance as much as
the inspections and services prescribed in this section.
NLB strongly recommends that log sheets be filled out for each piece
of
equipment or
accessory. The log sheets are valuable records which, when properly filled out, will serve as
a master record indicating the condition
of
each component and when inspections were
made. These records will also save time and money by aiding in the proper diagnosis
of
chronic problem areas.
