Daimler Trucks North America LLC distributes the following major service publications in paper and electronic
formats. Refer to
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. Each workshop/service manual section is divided into
subjects that can include general information, principles of operation, removal,
disassembly, assembly, installation, and specifications.
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 pre-trip 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.
Parts Technical Bulletins
Parts technical bulletins provide information on parts. These bulletins contain
lists of parts and BOMs needed to do replacement and upgrade procedures.

the publications listed above. In addition, the Service Solutions feature provides

edge base gathered from technicians and service personnel. Search results for
both documents and service solutions can be narrowed by initially entering ve-
hicle identification data.
