Foreword
When performed on a regular basis, lubricating the parts of your vehicle is the least costly way
of obtaining safe and reliable vehicle operation. Added benefits and savings occur when you
check that the engine, undercarriage, and noise emission control parts are in good working order
during lubrication.
This maintenance manual explains when you should lubricate parts and what to look for when
checking for wear or damage. For daily and weekly checks, refer to the vehicle driver’s manual.
IMPORTANT: Descriptions and specifications in this manual were in effect at the time of

General Information
Federal Law, Part 205: Transportation
Equipment Noise Emission Controls
Part 205, Transportation Equipment Noise Emission
Controls, requires the vehicle manufacturer to furnish, with each new vehicle, such written instructions
for the proper maintenance, use, and repair of the
vehicle by the ultimate purchaser to provide reasonable assurance of the elimination or minimization of
noise emission degradation throughout the life of the
vehicle. In compliance with the law, the Noise Emission Control Systems maintenance located in each
applicable group within this manual, in conjunction
with the vehicle service manual, provides these instructions to owners.
Normal Vehicle Use
The maintenance instructions contained in this
manual are based on average vehicle use and normal operating conditions. Unusual vehicle operating
conditions may require service at more frequent intervals.
Recommendations for Replacement
Parts
Replacement parts used for maintenance or for the
repair of noise emission control systems should be
genuine Freightliner parts. If other than genuine
Freightliner parts are used for replacements or for
the repair of components affecting noise emission
control, the owner should be sure that such parts are
warranted by their manufacturer to be equivalent to
genuine Freightliner parts in performance and durability.

Scheduled Maintenance Intervals, Description and
Use: 00–05
Description
Schedule I (severe service) applies to vehicles that
annually travel up to 6000 miles (10 000 kilometers)
or
that operate under severe conditions. Examples of
Schedule I usage include: operation on extremely
poor roads or where there is heavy dust accumulation; constant exposure to extreme hot, cold, salt-air,
or other extreme climates; frequent short-distance
travel; construction-site operation; city operation (fire
truck, garbage truck); or farm operation.
Schedule II (short-haul transport) applies to vehicles
up to
that annually travel
meters) and operate under normal conditions. Examples of Schedule II usage are: operation primarily
in cities and densely populated areas; local transport
with infrequent freeway travel; or high percentage of
stop-and-go travel.
Schedule III (long-haul transport) is for vehicles that
annually travel
meters), with minimal city or stop-and-go operation.
Examples of Schedule III usage are: regional delivery
that is mostly freeway miles; interstate transport; or
any road operation with high annual mileage.
The table under Maintenance Schedule Table
shows three different schedules of vehicle usage. For
each schedule the appropriate distance interval is
given for performing Initial Maintenance and for repeating each maintenance operation set (M1 through
M5). For Schedule I, the appropriate time interval is
also given.
The tables under Maintenance Interval Tables show
which maintenance operation set must be performed
at the actual distances (miles and kilometers) for
each maintenance schedule (or the actual hours of
operation for Schedule I). The schedule of actual distances (and hours) is based on the intervals given in
the Maintenance Schedule Table.
The tables under Maintenance Operation Sets
Tables list, in numerical order, the text reference
numbers and descriptions of
tions, and indicates all maintenance operation sets at
which each operation must be performed.
Each Maintenance Interval Operations Table (IM
through M5) lists the appropriate text reference
numbers and descriptions of only those maintenance
operations that must be performed at that maintenance operation set. Each maintenance operation set
is listed in a separate Maintenance Operations Table.

Use
Before placing your new vehicle in service, determine
the correct maintenance intervals that apply to your
intended use of the vehicle. Refer to the Maintenance Schedule Table to determine the distance (or
hour) interval at which each Maintenance Operation
Set must be performed to comply with your vehicle’s
schedule. For Schedule I vehicles equipped with an
hourmeter, use hours to determine maintenance intervals, rather than distance traveled.
When the vehicle reaches the actual distance (or
hours) given for an interval, refer to the Maintenance
Interval Tables to find the Maintenance Operation Set
that applies to that interval. Then perform the maintenance operations listed in the applicable Maintenance Interval Operation Table. Use the maintenance
operation reference numbers to find instructions in
the manual for completion of each operation.
Complete each Maintenance Operation Set at the
required interval. Then, when you have completed
Maintenance Operation Set M5 under the 32nd Maintenance Number listed in the Maintenance Interval
Table, repeat the pattern. The 33rd Maintenance
Number will begin at Maintenance Operation Set M1,
under the 1st Maintenance Number listed in the
Maintenance Interval Table.
NOTE: When performing operations for the 33rd
Maintenance Number, complete the M1 operations only, not the Initial Maintenance operations.
To determine the distance/hours for the 33rd Maintenance Number, add your schedule’s distance/hours
for the 1st Maintenance Number to the
distance/hours for the 32nd Maintenance Number,
then perform the operations listed in the applicable
table in the Maintenance Operations Tables. For the
34th Maintenance Number, add the distance/hours
for the 2nd to the distance/hours for the 32nd; continue this pattern for each successive Maintenance
Number.
