Business Class M2 Plus Maintenance Manual, 02/10/2023
Workshop/service manuals contain service and repair information for all vehicle
systems and components, except for major components such as engines,
transmissions, 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 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,
specifications, and procedures for adjustments and for checking the tightness of
fasteners. Maintenance manuals do not contain detailed repair or service
information. Maintenance manuals should not be used for covering plant quality
or quality assurance issues. The purpose of maintenance manuals is to
increase the life of the component being maintained. These are
recommendations, not requirements.
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 provide the latest service tips, field repairs, product
improvements, and related information. Some service bulletins are updates to
information 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 provide information on parts. These bulletins contain
lists of parts and BOMs needed to do replacement and upgrade procedures.
