Description
Category I (urban transport) applies to vehicles that
annually travel
up to 20,000 miles (32 000 kilome-
ters).
Category II (rural transport) applies to vehicles that
annually travel
over 20,000 miles (32 000 kilome-
ters).
The table under
Vehicle Maintenance Schedule Table
shows the two categories of vehicle usage. For each
category, the appropriate distance and time intervals
are given for performing Initial Maintenance and for
repeating each maintenance operation set (M1
through M3).
The table under
Maintenance Interval Table shows
which maintenance operation set must be performed
at the actual distances (miles and kilometers) or ac-
tual months of operation for each maintenance cat-
egory. The schedule of actual distances (and
months) is based on the intervals given in the Ve-
hicle Maintenance Schedule Table.
The table under
Maintenance Operation Sets lists, in
numerical order, the text reference numbers and de-
scriptions of
all maintenance operations, and indi-
cates all maintenance operation sets at which each
operation must be performed.
Each
Maintenance Interval Operations table (IM
through M3) lists the appropriate text reference num-
bers and descriptions of only those maintenance op-
erations that must be performed at that maintenance
operation set. Each maintenance operation set is
listed in a separate Maintenance Interval Operations
table.
Use
Before placing your new vehicle in service, determine
the maintenance category (Category I or II) that ap-
plies to your intended use of the vehicle. See the
Vehicle Maintenance Schedule Table to determine
the distance (or time) interval at which each mainte-
nance operation set must be performed for your cat-
egory of vehicle.
When the vehicle reaches the actual distance (or
months) given for an interval, see the Maintenance
Interval Table to find the maintenance operation set
that applies to that interval. Then perform the mainte-
nance operations listed in the applicable Mainte-
nance Interval Operations table. Use the mainte-
nance operation reference numbers to find
instructions in the manual for completion of each op-
eration.
Complete each maintenance operation set at the re-
quired interval. Then, when you have completed
maintenance operation set M3 under the 12th Main-
tenance Number listed in the Maintenance Interval
Table, repeat the pattern. The 13th 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 13th
Maintenance Number, complete the M1 opera-
tions only, not the Initial Maintenance opera-
tions.
To determine the distance/months for the 13th Main-
tenance Number, add your category’s
distance/months for the 1st Maintenance Number to
the distance/months for the 12th Maintenance Num-
ber, then perform the operations listed in the appli-
cable table in the Maintenance Interval Operations
tables. For the 14th Maintenance Number, add the
distance/months for the 2nd to the distance/months
for the 12th; continue this pattern for each succes-
sive Maintenance Number.

General Information
Federal Law, Part 205: Transportation
Equipment Noise Emission Controls
Part 205, Transportation Equipment Noise Emission
Controls, requires the vehicle manufacturer to fur-
nish, with each new vehicle, such written instructions
for the proper maintenance, use, and repair of the
vehicle by the ultimate purchaser to provide reason-
able assurance of the elimination or minimization of
noise emission degradation throughout the life of the
vehicle. In compliance with the law, the noise emis-
sion controls maintenance information located in
each applicable group of this manual, in conjunction
with the vehicle workshop manual, provides these
instructions to owners.
Normal Vehicle Use
The maintenance instructions contained in this
manual are based on average vehicle use and nor-
mal operating conditions. Unusual vehicle operating
conditions may require service at more frequent in-
tervals.
Recommendations for Replacement
Parts
Replacement parts used for maintenance or repair of
noise emission controls should be genuine Freight-
liner Custom Chassis Corporation (FCCC) parts. If
other than genuine FCCC parts are used for replace-
ment or repair of components affecting noise emis-
sion control, the owner should be sure that such
parts are warranted by their manufacturer to be
equivalent to genuine FCCC parts in performance
and durability.
Freightliner Noise Emissions Warranty
See the vehicle owner’s warranty information book
for warranty information concerning noise emission
controls.
Tampering With the Noise Controls is
Prohibited
Federal law prohibits the following acts or the caus-
ing thereof: (1) the removal or rendering inoperative
by any person other than for purposes of mainte-
nance, repair, or replacement, of any device or ele-
ment of design incorporated into any new vehicle for
the purpose of noise control prior to its sale or deliv-
ery to the ultimate purchaser or while it is in use, or
(2) the use of the vehicle after such device or ele-
ment of design has been removed or rendered inop-
erative by any person. Among those acts presumed
to constitute tampering are the acts listed below:
A. Removal of engine noise-deadening panels.
B. Removal of, or rendering inoperative, the engine
speed governor so as to allow engine speed to
exceed manufacturer’s specifications.
C. Removal of, or rendering inoperative, the fan
clutch, including by-passing the control on any
thermostatic fan drive to cause it to operate con-
tinuously.
D. Removal of the fan shroud.
E. Removal of, or rendering inoperative, exhaust
system components, including exhaust pipe
clamping.
F. Removal of air intake components.
G. Removal of hood liners (noise-deadening pan-
els).
Maintenance Instructions
Scheduled intervals are in the maintenance table in
this Group. A "Verification of Inspections Log" follows,
and should be filled in each time the noise emission
controls on the vehicle are maintained or repaired.
