Why is there a service schedule on my compressor?

It’s preventative maintenance. Your compressor needs servicing regularly to help prevent downtime. Consider this if your Compressor wasn’t working what would be the consequences? No production possibly? How much would this cost your business for every hour of non-production? Keeping a good service schedule means the service items are changed regularly and so less likely to fail. Plus any potential faults can be identified and remedied without every getting to the breakdown stage.
