I would recommend adding PM time to perform when you add a PM schedule. Please don't "wing it", but use your own historical data. Export out a 3 year total of you workorders, combine the hours through some excel magic, and create a pivot table by equipment type. Use these values as a starting point and adjust as necessary. This has several benefits. You can bench mark your technicians, you can properly distribute work load, and you can track efficiency year to year. Please remember that to accomplish something you have never done, you must try somethings you have never tried before.
