General Information 00 Determining Scheduled Maintenance Intervals: 00–01 Determining Scheduled Maintenance Intervals operating conditions. Unusual vehicle operating conditions may require service at more frequent intervals. Performing regular maintenance on your Freightliner vehicle will help ensure that your vehicle delivers safe reliable service and optimum performance for years to come. Failure to follow a regular mainte- nance program can result in inefficient operation and unscheduled down time. To determine the correct maintenance intervals for your vehicle you must first determine the type of ser- vice or conditions the vehicle will be operating in.
Generally, over-the-road vehicles operate under con- ditions that fall within one of the two types of service described. Before placing your new vehicle in ser- vice, determine the type of service (Service Schedule I or II) that applies to the intended use of the vehicle. After determining the vehicle’s type of service, refer to the service schedule table or the vehicle mainte- nance schedule table, to determine how often main- tenance should be performed. When the vehicle reaches the distance given for a maintenance interval, see the Maintenance Interval Operation Table for a list of the maintenance opera- tions to be performed at that maintenance interval.
Use the maintenance operation reference numbers to find detailed instructions in the manual on each op- eration. Types of Service Service Schedule I (short-haul transport) applies to vehicles that annually travel less than 60,000 miles (100 000 kilometers) and operate under normal con- ditions. Examples of Schedule I usage are: operation primarily in cities and densely populated areas; local transport with infrequent freeway travel; or high per- centage of stop-and-go travel. Service Schedule II (long-haul transport) is for ve- hicles that annually travel more than 60,000 miles (100 000 kilometers) with minimal city or stop-and-go operation. Examples of Schedule II usage are:
re- gional delivery that is mostly freeway miles; interstate transport; or any road operation with high annual mileage. NOTE: Maintenance instructions in this manual are based on average vehicle use and normal Cascadia Maintenance Manual, August 2015 00/1
