Maintenance and Specifications NOISE EMISSIONS WARRANTY, PROHIBITED TAMPERING ACTS AND MAINTENANCE On January 1, 1978, Federal regulation became effective governing the noise emission on trucks over 10,000 lbs. (4,536 kg) GVWR (Gross Vehicle Weight Rating). The following statements concerning prohibited tampering acts and maintenance, and the noise warranty found in the Warranty Guide, are applicable to complete chassis cabs over 10,000 lbs. (4,536 kg) GVWR. Tampering with noise control system prohibited Federal law prohibits the following acts or the causing thereof: (1) The removal or rendering inoperative by any person other than for purposes of maintenance, repair or replacement of any device or element of design incorporated into any new vehicle for the purpose of noise control prior to its sale or delivery to the ultimate purchaser or while it is in use, or (2) the use of the vehicle after such device or element of design has been removed or rendered inoperative by any person. Among those acts which the U.S. Environmental Protection Agency may presume to constitute tampering are the acts listed below: • Removal of hood blanket, fender apron absorbers, fender apron barriers, underbody noise shields or acoustically absorptive material. • Tampering or rendering inoperative the engine speed governor, so as to allow engine speed to exceed manufacturer's specifications. The complexity of the diesel engine makes it so the owner is discouraged from attempting to perform maintenance other than the services described in this supplement. If you experience difficult starting, rough idling, excessive exhaust smoke, a decrease in engine performance or excess fuel consumption, perform the following checks: • a plugged or disconnected air inlet system or engine air filter element. • water in the fuel filter/water separator. • a clogged fuel filter. • contaminated fuel. • air in the fuel system, due to loose connections. • an open or pinched sensor hose. • check engine oil level. • wrong fuel or oil viscosity for climactic conditions. If these checks do not help you correct the engine performance problem you are experiencing, consult an authorized dealer. 64 2012 Diesel (67l) Supplement, 3rd Printing USA (fus)

NOISE EMISSIONS WARRANTY, PROHIBITED TAMPERING ACTS
AND MAINTENANCE
On January 1, 1978, Federal regulation became effective governing the noise
emission on trucks over 10,000 lbs. (4,536 kg) GVWR (Gross Vehicle Weight
Rating). The following statements concerning prohibited tampering acts and
maintenance, and the noise warranty found in the
Warranty Guide
, are
applicable to complete chassis cabs over 10,000 lbs. (4,536 kg) GVWR.
Tampering with noise control system prohibited
Federal law prohibits the following acts or the causing thereof: (1) The
removal or rendering inoperative by any person other than for purposes
of maintenance, repair or replacement of any device or element of design
incorporated into any new vehicle for the purpose of noise control prior
to its sale or delivery to the ultimate purchaser or while it is in use, or
(2) the use of the vehicle after such device or element of design has
been removed or rendered inoperative by any person.
Among those acts which the U.S. Environmental Protection Agency may
presume to constitute tampering are the acts listed below:
•
Removal of hood blanket, fender apron absorbers, fender apron
barriers, underbody noise shields or acoustically absorptive material.
•
Tampering or rendering inoperative the engine speed governor, so as
to allow engine speed to exceed manufacturer’s specifications.
The complexity of the diesel engine makes it so the owner is discouraged
from attempting to perform maintenance other than the services
described in this supplement.
If you experience difficult starting, rough idling, excessive exhaust
smoke, a decrease in engine performance or excess fuel consumption,
perform the following checks:
•
a plugged or disconnected air inlet system or engine air filter element.
•
water in the fuel filter/water separator.
•
a clogged fuel filter.
•
contaminated fuel.
•
air in the fuel system, due to loose connections.
•
an open or pinched sensor hose.
•
check engine oil level.
•

If these checks do not help you correct the engine performance problem
you are experiencing, consult an authorized dealer.
