Caution

There is a risk of damag‐

ing  the  decoupling  ele‐

ment between the partic‐

ulate  filter  and  NOx

reduction  catalytic  con‐

verter.  When  removing

and installing:

♦

Do not bend the decou‐

pling element more than

10°.

♦

Do not stretch the decou‐

pling element.

♦

Do not damage the wire

mesh on the decoupling

element.

♦

Use the Transportation

Lock - T10404- to secure

the decoupling element

from stretching.
