Workshop/Service
Manual
Workshop/service manuals contain service and repair information for all vehicle
systems and components, except for major components such as engines, trans-
missions, and rear axles. For service and repair information of major compo-
nents, refer to the OEM website. A listing of many OEM websites can be found
in Section 00.02 of the workshop/service manual. Each workshop/service
manual section is divided into subjects that can include general information,
principles of operation, removal, disassembly, assembly, installation, and specifi-
cations.
Maintenance Manual
Maintenance manuals contain routine maintenance procedures and intervals for
vehicle components and systems. They have information such as lubrication
procedures and tables, fluid replacement procedures, fluid capacities, specifica-
tions, and procedures for adjustments and for checking the tightness of fasten-
ers. Maintenance manuals do not contain detailed repair or service information.
Driver’s/Operator’s
Manual
Driver’s/operator’s manuals contain information needed to enhance the driver’s
understanding of how to operate and care for the vehicle and its components.
Each manual contains a chapter that covers pretrip and post-trip inspections,
and daily, weekly, and monthly maintenance of vehicle components.
Driver’s/operator’s manuals do not contain detailed repair or service information.
Service Bulletins
Service bulletins provide the latest service tips, field repairs, product improve-
ments, and related information. Some service bulletins are updates to informa-
tion in the workshop/service manual. These bulletins take precedence over
workshop/service manual information, until the latter is updated; at that time, the
bulletin is usually canceled. The service bulletins manual is available only to
dealers. When doing service work on a vehicle system or part, check for a valid
service bulletin for the latest information on the subject.
IMPORTANT: Before using a particular service bulletin, check the current
service bulletin validity list to be sure the bulletin is valid.

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
, 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
, 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
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.
