4.4.2 Installation of dust extractor adaptor
Open the front door and pull out the dust bin, take out the dust extractor adaptor and fix the dust
extractor adaptor to the main unit. as
Fig.12.
2’’(50mm), 4’’(100mm) and 6’’ (150mm) hoses can be used, see Fig.12.
When you choose 6’’(150mm) hose, connect hose to the main unit directly.
When you choose 4’’ (100mm) hose and 2’’ (50mm) hose, install dust extractor adaptor to the
main unit first. Then connect hose to the dust extractor adaptor. If you need to connect two 4’’
(100mm) hoses, you should add a 4’’ (100) port, which needs additional purchase.

Grounding:
Since plastic hose is abundant, relatively inexpensive, easily assembled and air tight, it is a very
popular material for conveying dust. However, plastic flex-hose and plastic duct is an insulator,
and dust particles moving against the walls of the plastic hose create a static electricity build up.
This charge will build until it discharges to a ground. If a grounding medium is not available to
prevent static electrical build up, the electrical charge will arc to the nearest grounded source.
This electrical discharge may cause an explosion and subsequent fire inside the system.
You need to lead out the spiral copper wire or the iron wire on the bellow for grounding. Also, utili
zing the machine shell, you can ground the wires by connecting them to the set screws on the d
ust port.
Ensure each machine is continuously grounded to the grounding terminal in your electric
service panel.
