Integrated Dust Extraction (see figure C)
For basic dust collection, use the dust bag 21
provided.
– Press the clip of the dust bag 21 together
and slide the dust bag over the saw dust
ejector 25. The clip must engage into the
groove of the saw dust ejector.
During sawing, the dust bag must never come in-
to contact with the movable machine parts.
Always empty the dust bag in good time.
Check and clean the dust bag each time af-
ter using.
When sawing aluminium, remove the dust
bag to avoid the risk of fire.
External Dust Extraction
For dust extraction, a vacuum hose (size
Ø 36 mm) can also be connected to the dust
ejector.
– Connect the vacuum hose with the sawdust
ejector 25.
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.
