Freightliner LLC distributes the following major service publications.


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. Each workshop/service manual section is divided into
subjects that can include general information, principles of operation, removal,
disassembly, assembly, installation, specifications, and troubleshooting.

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, procedures for adjustments and for checking the tightness of fasteners.
Maintenance manuals do not contain detailed repair or service information.


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 inspection and daily mainte-
nance of vehicle components. Driver’s/operator’s manuals do not contain de-
tailed repair or service information.

Parts Technical Manual

Freightliner LLC publishes this manual to aid in the identification of serviceable
replacement vehicle parts. This manual is used in conjunction with the parts
book and the service parts catalog microfiche.

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.

Recall Bulletins

These bulletins pertain to special situations that involve service work or replace-
ment of parts in connection with a recall notice. Recall bulletins pertain to mat-
ters of vehicle safety. All bulletins are distributed to dealers; customers receive
notices that apply to their vehicles.

Field Service

This publication is concerned with non-safety-related service work or replace-
ment of parts. All field service modifications are distributed to dealers; custom-
ers receive notices that apply to their vehicles.
