Integrated Dust Extraction (see figure F)
– Mount the dust bag 1 onto the sawdust ejec-
tor 2.
During sawing, the dust bag must never come in-
to contact with the movable machine parts.

External Dust Extraction
For dust extraction, a vacuum hose (size
Ø 36 mm) can also be connected to the dust
ejector.
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.
