Establishing a preventive maintenance program at your plant can keep vehicles and equipment in satisfactory operating condition at the lowest possible cost. The first step in setting up a preventive maintenance program is to rate your maintenance shop. Do you usually have on-hand most of the parts you need to complete a repair? Do you have a long line of broken equipment waiting on repairs? Do your mechanics seem happy? Are tools easy to locate and readily accessible? Once you have rated your shop, ask yourself how it could be better. For a preventive maintenance program to operate effectively, it must (a) be designed around the specific vehicles and equipment it is supposed to maintain, (b) fit the conditions that the equipment operates in, change when vehicles, equipment, and conditions change, and (d) center on inspection, not repair. An efficient repair shop should have proper organization and up-to-date tools and equipment. Maintenance problems and tasks should be completed in order of priority rather than on a first-come-first-serve basis. Good records must be kept and organized, and proper communications maintained with the rest of the plant.
