What is Preventive Maintenance?
Preventive maintenance (PM) is the practice of regularly maintaining equipment to prevent unexpected failures. Instead of waiting for something to break, you proactively service it on a schedule.
Why Preventive Maintenance Matters
The cost of unplanned downtime far exceeds the cost of regular maintenance. Studies show that preventive maintenance can:
- Reduce equipment failures by up to 70%
- Extend asset lifespan by 20-40%
- Lower overall maintenance costs by 25-30%
- Improve safety and compliance
Creating a Preventive Maintenance Schedule
Step 1: Inventory Your Assets
Start by listing all equipment that requires maintenance. Include specifications, warranty information, and manufacturer recommendations.
Step 2: Determine Maintenance Tasks
For each asset, identify what maintenance is needed: inspections, cleaning, lubrication, part replacements, calibration, etc.
Step 3: Set Frequencies
Decide how often each task should be performed. This could be based on time (monthly, quarterly) or usage (every 1,000 hours).
Step 4: Assign Responsibilities
Determine who will perform each task. Some maintenance can be done in-house; other tasks may require external technicians.
Step 5: Track and Document
Use software like Stocktric to schedule maintenance, send reminders, and maintain complete service records.
Common Preventive Maintenance Tasks
- Visual inspections for wear and damage
- Cleaning and debris removal
- Lubrication of moving parts
- Filter replacements
- Calibration and adjustments
- Software updates
- Safety checks
Conclusion
A well-implemented preventive maintenance program is an investment that pays for itself many times over. Start small, be consistent, and continuously improve your processes.
