I. Overview

Mobile equipment inspections and service intervals are essential for maintaining and operating emergency and non-emergency mobile equipment.

II. Safety Inspections

A. All equipment:

1. Quarterly by the district's mechanic or hired agency.

III. Compliance Inspections

A. Fire Engines, Utilities, Ambulances, Trucks, Water Tenders, Squads and all other regulated vehicles (Vehicle Code 34500):

1. At 90 day intervals by the district's mechanic or hired agency.

IV. Administrative Inspections

Group 2: Engines, Squads, Trucks, Water Tenders & Ambulances:

Twice annually, the first inspection to be made in the month of April and the next inspection in October.

Group 1: All other equipment:

Annually.

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
