Maintenance Operations

What is the purpose of preventive maintenance?

• The purpose of preventive maintenance is to increase equipment failure and shorten the lifespan of assets.

• The purpose of preventive maintenance is to ignore equipment issues and let them worsen over time.

• The purpose of preventive maintenance is to randomly select equipment for maintenance without any planning.

• The purpose of preventive maintenance is to prevent equipment failure and prolong the lifespan of assets.

Give an example of a preventive maintenance task.

• Changing a light bulb

• Painting a room

• Inspecting and cleaning HVAC filters

• Mowing the lawn

Explain the difference between corrective and preventive maintenance.

• Corrective maintenance is proactive, preventing issues before they happen, while preventive maintenance is reactive, fixing issues after they occur.

• Corrective maintenance involves regular inspections, while preventive maintenance only addresses issues when they arise.

• Corrective maintenance is reactive, fixing issues after they occur, while preventive maintenance is proactive, preventing issues before they happen.

• Corrective maintenance is more cost-effective than preventive maintenance.

What is predictive maintenance and how does it differ from preventive maintenance?

• Predictive maintenance does not require any planning, unlike preventive maintenance.

• Predictive maintenance relies on guesswork, while preventive maintenance is data-driven.

• Predictive maintenance uses data and analytics to predict equipment failure, while preventive maintenance follows a set schedule of routine tasks.

• Predictive maintenance is more expensive than preventive maintenance.

Why is routine maintenance important in the context of maintenance operations?

• Routine maintenance helps prevent unexpected breakdowns, prolongs equipment lifespan, maintains optimal performance, and reduces repair costs.

• Routine maintenance increases the likelihood of breakdowns.

• Routine maintenance does not impact equipment performance.

• Routine maintenance is unnecessary and a waste of resources.

Provide an example of routine maintenance in a manufacturing setting.

• Replacing the light bulbs in the break room

• Occasionally painting the walls of the manufacturing facility

• Upgrading the office computers

• Regularly inspecting and cleaning conveyor belts in a factory to prevent debris buildup and ensure smooth operation.

What is the main goal of scheduled maintenance?

• Shorten machinery lifespan

• Increase energy consumption

• Encourage equipment failure

• Prevent equipment failure and prolong machinery lifespan

How does scheduled maintenance help in reducing downtime?

• By proactively identifying and addressing potential issues before they cause a breakdown.

• By ignoring maintenance altogether

• By randomly selecting maintenance tasks without a plan

• By waiting for breakdowns to occur before addressing issues

What are some common tools used in preventive maintenance?

• screwdriver set

• inspection checklists, lubrication equipment, vibration analysis tools, thermographic cameras, ultrasonic testing devices

• paintbrush and roller

• hammer and nails

Describe the steps involved in conducting a corrective maintenance task.

• Ignore the issue, wait for it to resolve on its own

• Identify the issue, plan repairs, acquire resources, perform maintenance, test equipment, document maintenance.

• Start repairs without identifying the problem

• Skip testing equipment after maintenance
