HANDLING OF PARTS FOR MEETING THE EXTERNAL NOISE
CONTROL REGULATION
KK-XZU215C
To comply with the external noise control regulation, parts for
external noise reduction, such as sound-insulating materials
(cover, rubber) sound-absorbing materials, muffler etc., are
equipped on the cab, the engine and the chassis. Since the
parts for external noise reduction and their fitting locations are
depending on the vehicle model, refer to the corresponding
explanatory example drawing shown in the following. To ensure
external noise reductions, following items must be observed
when mounting a superstructure.
(1) The parts for external noise reduction must not be modified
or detached, since their specifications are determined to
comply with the limiting value of the external noise
regulation. The position and/or direction of the tail pipe
must also not be changed.
(2) If the parts for external noise reduction are temporarily
detached for mounting a superstructure, handle them
carefully to prevent their deformation and/or damage, and
be sure attach them on original position after completion of
mounting the superstructure.
If the parts for external noise reduction have been
deformed and/or damaged, replace them with genuine
parts and never use rectified parts.
