What should guide the frequency schedule of preventative maintenance?

The frequency schedule of preventative maintenance should indeed be guided significantly by the amount of continuous usage of the equipment. This is because equipment that is used more frequently is more likely to experience wear and tear, leading to potential failures if not adequately maintained. By prioritizing maintenance based on usage, technicians can ensure that the equipment remains in optimal operating condition, minimizing downtime and avoiding costly repairs resulting from neglect.

Monitoring the continuous usage helps in understanding how the equipment performs under typical working conditions and allows for adjustments in maintenance schedules that can enhance reliability and lifespan. While other factors like the age of the equipment, type of equipment, and manufacturer's suggestions are important considerations, usage directly relates to the condition and the specific maintenance needs of the equipment, making it a critical factor in scheduling preventative maintenance.
