Determining Scheduled Maintenance Intervals: 00-01

122SD mm 00.00.01

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 maintenance program can result in inefficient operation and unscheduled down time.

Determine the correct maintenance intervals and operations for your vehicle as follows.

  1. Using Table., determine the type of service or conditions the vehicle will be operating in. Generally, most vehicles operate under conditions that fall within one of the four types of service listed.

  2. Using Table., determine how often maintenance should be performed, based on the vehicle's service schedule.

  3. When the vehicle reaches the distance (or hours of operation) given for a maintenance interval, as shown in the appropriate table in , see the appropriate Maintenance Interval Operation Table (listed below) for a list of the maintenance operations to be performed.

Initial Maintenance (IM) Operations: 00-03

M1 Maintenance Interval Operations: 00-04

M2 Maintenance Interval Operations: 00-05

M3 Maintenance Interval Operations: 00-06

Use the maintenance operation reference numbers in the Maintenance Interval Operation Tables to find detailed instructions in the manual on each operation.

Note: Maintenance instructions in this manual are based on average vehicle use and normal operating conditions. Unusual vehicle operating conditions may require service at more frequent intervals.
