1.1.8 What impact does lack of maintenance have on budget forecasting? (p. 9)
Fleet managers will be unable to forecast maintenance budget, not only from a personnel aspect, but from an outlay of cash of parts and supplies
1.1.9 What impact does a thorough maintenance program have on vehicle remarketing?
Those with accurate, proven PM records may sell for more than those without
1.2.1 What are the two major components of a PM program?(p. 10)
1.2.2 List six principal sources for determining maintenance actions. (p. 13)
6 Even a fleet comprised mostly of light duty vehicles may have a significant number of vehicles where mileage standards are not reflective of use.
1.2.3 What are two primary factors for determining service intervals? (p. 12)
Mileage and Idle or not
1.2.4 When would fuel consumption be the preferred factor for determining PM interval? (p. 14)
Vehicles that incur significant or regular idle time, but are not equipped with hour meters (most light duty vehicles)
1.2.5 Why would fuel consumption be important to PM scheduling? (p.14)
Fuel transactions for all fleet vehicles are metered by the dispenser and should be uploaded to fleet management software that tracks cumulative fuel consumption.
The software can trigger scheduling a PM at a preset number of gallons or liters consumed
