External Dust Extraction
For dust extraction, a vacuum hose (size
Ø 36 mm) can also be connected to the dust
ejector 21.
The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.
