PREVENTIVE MAINTENANCE SCHEDULE Disconnect the battery ground strap whenever you work on the fuel sys- tem or the electrical system. When you work around fuel, do not smoke or work near heaters or other fire hazards. Keep an approved fire ex- tinguisher handy. Failure to comply may result in death, personal injury, equipment or property damage. WARNING! When working underneath the vehi- cle without appropriate safety stands but with the wheels on the ground (not supported), make sure that (1) the vehicle is on hard level ground, (2) the parking brake is applied, (3) all wheels are blocked (front and rear) and (4) remove the ignition key so that the engine cannot be started.
Failure to comply may result in death, personal injury, equipment or property damage. WARNING! The following pages contain a table of maintenance tasks with the related intervals for each task on the right side of the table. The top of the table displays a guide to a maintenance interval and its schedule. Some tasks are dependent on the vehicle application. These tasks will be shown as separate tasks and will have the words HIGHWAY”, “CITY DELIVERY” or “OFF-HIGHWAY” after the description. These tasks are differentiated because they are dependent on the vehicle’s operating environment. WARNING!
Always support the vehicle with ap- propriate safety stands if it is neces- sary to work underneath the vehicle. A jack is not adequate for this pur- pose. Failure to comply may result in death, personal injury, equipment or property damage. 5 WARNING! Never start or let the engine run in an enclosed, unventilated area. Ex- haust fumes from the engine contain carbon monoxide, a colorless and odorless gas. Carbon monoxide can be fatal if inhaled. Failure to comply may result in death, personal injury, equipment or property damage. On highway is defined for applications where the vehicle is NOT used off of a paved road during normal operation.
City Delivery is defined for applications where frequent start and stopping is required during normal operation and the highway is used infrequently and for short periods of time. 5-10 Y53-6077-1B1 (03/17)
