Preventive maintenance is a schedule of
planned maintenance actions aimed at theprevention of breakdowns and failures.
The primary goal of preventivemaintenance is to prevent the failure of
equipment before it actually occurs. Designed to:
Preserve and enhance equipment reliabilityby replacing worn components
Ensure machine failures are not the cause forworkplace mishaps.

A written preventive and predictive maintenance
system must be in place
Equipment must be replaced or repaired on aschedule, following manufacturersrecommendations
Documented records of maintenance and repairsmust be kept
The system must include maintenance of hazardcontrols such as machine guards, exhaustventilation, mufflers, control circuits and devices,etc.

P! system aligns with asafety managementprogram to:
Prevent in"uries caused bymalfunctioning equipment
#ncrease automation $educe losses due toproduction delays
#mprove quality %ust&in&time manufacturing Provides a more organi'edwork environment.

Some advantages of a PM system include: Reduced production downtime
Conservation of assets and increased lifeexpectancy of assets (both machine and human)
Ensuring all equipment safety features arefunctioning properly
Reduced cost of repairs by reducing secondary
failures
Quality products
Identification of equipment with excessivemaintenance costs

PM program risks couldinclude: Damage to adjacent equipmentduring a PM task
Damage due to an error inreinstalling equipment into itsoriginal location
Damage due to the installation ofnew parts.

Things to consider after completing amaintenance operations: Ensure equipment meets manufacturersspecification
Review job hazard analysis (JHA) to ensureequipment alterations or equipment maintenancedid not introduce new hazards
Conduct machine checks to ensure all features,especially safety devices, are functioning properly
Ensure employees are aware of any changes toequipment and/or operating procedures.

Three keys for a successfulPM system: Scheduling: Should be
automated to the maximumextent possible
Execution: Should be donebefore an actual break downoccurs
Quality: Should have a formal
process for checking the qualityof repairs.

P! focus should be on: (leaning
)ubrication and inspection
(orrecting de*ciencies
+peration of safety devices.
Pre&determined partreplacement should beminimal and done only
where evidence clearlyindicates wear&outcharacteristics.

When PM data is missing
capture techniques shouldlook at: Structural/facility
Age exploration programs
Statistical analysis Safety inspection data.
Cost should not be aprimary factor in decidingagainst data collection fora PM system.

,ays to motivate your P! workers include:Establishing e-ective training programs
Establishing inspection and preventivemaintenance as a recogni'ed important part ofthe overall maintenance program includingfollow&ups
ssigning competent responsible people to thepreventive maintenance program
/etting high standards
Publici'ing reduced costs with improved up&timeand revenues and employee safety which are theresult of an e-ective preventive maintenancesystem.
