WHAT IS PREVENTIVE MAINTENANCE ?

Preventive maintenance is a schedule of planned maintenance actions aimed at the prevention of breakdowns and failures.

The primary goal of preventive maintenance is to prevent the failure of equipment before it actually occurs.

Designed to: Preserve and enhance equipment reliability

by replacing worn components

Ensure machine failures are not the cause for workplace mishaps.

PM REQUIREMENTS

A written preventive and predictive maintenance system must be in place .

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 SYSTEM

A PM system aligns with a safety management program to:

Prevent injuries caused by malfunctioning equipment.

Increase automation

Reduce losses due to production delays

Improve quality

Just-in-time manufacturing

Provides a more organized work environment.

ADVANTAGES 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 .

Timely, routine repairs circumvent fewer large-scale

repairs.

THE LAW OF PM PROGRAMS

THE HIGHER THE VALUE OF PLANT

ASSETS AND EQUIPMENT PER SQUARE

FOOT OF FACILITY, THE GREATER WILL

BE THE RETURN.

THINGS TO CONSIDER

Things to consider after completing a maintenance operations:

Ensure equipment meets manufacturer’s specification.

Review job hazard analysis (JHA) to ensure equipment

alterations or equipment maintenance did not introduce

new hazards.

Conduct machine checks to ensure all features,

especially safety devices, are functioning properly.

Ensure employees are aware of any changes to

equipment and/or operating procedures.

A SUCCESSFUL PM SYSTEM

Three keys for a successful PM system:

Scheduling: Should be automated to the maximum extent possible.

Execution: Should be done before an actual break down occurs.

Quality: Should have a formal process for checking the quality of repairs.
