What is Preventive Maintenance?What is Preventive Maintenance?
Preventive maintenance is a schedule of plannedmaintenance actions aimed at the prevention of
breakdowns and failures.
The primary goal of preventive maintenance is to
prevent the failure of equipment before it actuallyoccurs.
Designed to:
Preserve and enhance equipment reliability
by replacing worn components
Ensure machine failures are not the cause for
workplace mishaps.

Preventive Maintenance
VPP Requirements for
Preventive Maintenance
A written preventive and predictive maintenancesystem must be in place
VPP Federal Register Notice 65:45649-45663, 7/24/2000
Equipment must be replaced or repaired on a
schedule, following manufacturers recommendations Documented records of maintenance and repairs must
be kept
The system must include maintenance of hazard
controls such as machine guards, exhaust ventilation,mufflers, control circuits and devices, etc.

Need for PM SystemNeed for PM System
A PM system aligns with asafety management program
to:
Prevent injuries caused by
malfunctioning equipment
Increase automation
Reduce losses due to
production delays
Improve quality Just-in-time manufacturing

Advantages of a PM SystemAdvantages of a PM System
Some advantages of a PM system include: Reduced production downtime
Conservation of assets and increased life
expectancy of assets (both machine and human)
Ensuring all equipment safety features are
functioning properly
Reduced cost of repairs by reducing secondary failures
Quality products
Identification of equipment with excessive maintenance
costs
Improved safety and quality conditions.

Errors of a PM SystemErrors of a PM System
PM system errors couldinclude:
Damage to an adjacent
equipment
during a PM task
Damage due to an error in
reinstalling equipment into its
original location
Damage due to the installationof new parts.

Things To ConsiderThings To Consider
Things to consider after completing amaintenance operations:
Ensure equipment meets manufacturers specification
Review job hazard analysis (JHA) to ensure equipment
alterations or equipment maintenance did not introducenew hazards not included on the JHA
Conduct machine checks to ensure all feature,
especially safety devices, are functioning properly
Ensure employees are aware of any changes toequipment and/or operating procedures.

A Successful PM SystemA Successful PM System
Three keys for asuccessful PM system:
Scheduling: Should be
automated to the maximum
extent possible Execution: Should be done
before an actual break down
occurs
Quality: Should have aformal process for checking
the quality of repairs.

PM FocusPM Focus
PM focus should be on: Cleaning
Lubrication and inspection
Correcting deficiencies
Operation of safety devices.
Pre-determined parts
replacement should be
minimal and done only whereevidence clearly indicates
wear-out characteristics.Image courtesy of www.defenselink.mil

Data AbsenceData Absence
When data on PM is absencesome techniques which can beused to assist in its creationare:
Structural/facility Age exploration programs
Statistical analysis
Safety inspection data.
Cost should not be a primaryfactor in deciding against datacollection for a PM system. Image courtesy of www.defenselink.mil

Preventive MaintenanceWorkersPreventive MaintenanceWorkers
Ways to motivate your PM workers include: Establishing effective training programs
Establishing inspection and preventive maintenance
as a recognized, important part of the overall
maintenance program, including follow-ups Assigning competent, responsible people to the
preventive maintenance program
Setting high standards
Publicizing reduced costs with improved up-time andrevenues and employee safety, which are the result
of an effective preventive maintenance system.
