Model FS 450 Brushcutters - Series 4128

Permissible muffler / shroud combinations

TI 10.2000 introduced new mufflers (with modified exhaust outlet) and matching new shrouds (with modified
exhaust "windows") for the model FS 450 brushcutters.
As already pointed out in the aforementioned TI, the previous version of parts cannot be combined with
the new version of parts!
The following points must therefore be noted when replacing one of these components:
.   The previous mufflers and shrouds may only be fitted in combination
.   The new mufflers and shrouds may only be fitted in combination
Important! If the old and new versions are mixed in combination, uncontrolled routing of the hot exhaust gases
may result in damage to the plastic components (e.g. fuel tank and shroud)!

Permissible combinations
(The parts can be identified by means of the sprayed-on or embossed part number and by comparison with the
illustrations in TI 10.2000, as well as in the current spare parts documentation)

Most of these PDFs embed fonts with a shifted character map, so the text above was recovered rather than copied — read it as a faithful but imperfect transcription, and treat the page image above each block as the authority where the two disagree — the figures exist only there, because they are vector drawings that text extraction cannot keep.
