Freightliner Cargo Maintenance Instruction - page 1

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 Control Systems maintenance located in each
applicable group within 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 for the
repair of noise emission control systems should be
genuine OEM parts. If other than genuine OEM parts
are used for replacements or for the repair of compo-
nents affecting noise emission control, the owner
should be sure that such parts are warranted by their
manufacturer to be equivalent to genuine OEM parts
in performance and durability.

Noise Emissions Warranty

Refer to the vehicle owner’s warranty information
book for warranty information concerning noise emis-
sion control systems.

Tampering With the Noise Control
System 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 the engine speed gover-

nor inoperative 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 sys-

tem components, including exhaust pipe clamp-
ing.

F.

Removal of air intake system components.

G. Removal of hood liners (noise-deadening pan-

els).

Maintenance Instructions

Scheduled intervals are in the maintenance tables in
Group 00 of this manual. A "Verification of Inspec-
tions Log" is contained in the following table, and
should be filled in each time the noise emission con-
trols on the vehicle are maintained or repaired.
