Determining Scheduled
Maintenance 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.
Determine the correct maintenance intervals and op-
erations for your vehicle as follows.
1. Using Table 1 , determine the type of service or
conditions the vehicle will be operating in. Gener-
ally, most vehicles operate under conditions that
fall within one of the four types of service listed.
2. Using Table 2 , determine how often maintenance
should be performed, based on the vehicle’s ser-
vice schedule.
3. When the vehicle reaches the distance (or hours
of operation) given for a maintenance interval, as
shown in the appropriate table in
Vehicle Main-
tenance Schedule Tables: 00-02 , see the ap-
propriate Maintenance Interval Operation Table
(listed below) for a list of the maintenance opera-
tions to be performed.
