V. Preventive Maintenance Service
A. A system of complete service and inspections covering all operating components of each vehicle provides the basic preventive maintenance tool. These inspections and corrective actions are designed for an emergency fleet where use dictates maintenance levels at a much higher degree than conventional oil change and lubrication intervals.
"A" Service: Group 2 - 1,000 miles or 30 days.
"B" Service: Group 1 & 2 - 4,000 or 90 days.
"C" Service: All Vehicles - Annually or 12,000 miles.
Manufacturer's recommendation, not to exceed six months or 150 hours oil change. All other services annually.
VI. Preventive Maintenance Instructions
A. Inspections covered by these instructions include pump engines where applicable and will be recorded as one unit
