# Dust/chip extraction

The dust from materials such as lead paint, some types of wood, minerals and metal can be harmful to human health. Touching or breathing in this dust can trigger allergic reactions and/or cause respiratory illnesses in the user or in people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as carcinogenic, especially in conjunction with wood treatment additives (chromate, wood preservative). Materials containing asbestos may only be machined by specialists.

- Use a dust extraction system that is suitable for the material wherever possible.
- Provide good ventilation at the workplace.
- It is advisable to wear a P2 filter class breathing mask.

The regulations on the material being machined that apply in the country of use must be observed.

The dust/chip extraction system can be blocked by dust, chips or fragments of the workpiece.

- Switch the power tool off and pull the mains plug out of the socket.
- Wait until the saw blade has come to a complete stop.
- Determine the cause of the blockage and eliminate it.

- Avoid dust accumulation at the workplace. Dust can easily ignite.

- To prevent the risk of fire when sawing aluminium, empty the lower saw blade cover and do not use chip extraction.

##

You can open the lower saw blade cover (44) to remove workpiece fragments and large chips.

- Switch the power tool off and pull the mains plug out of the socket.
- Wait until the saw blade has come to a complete stop.
- Turn the power tool on its side.
- Open the base grid (31) (see figure a).
- Gently pull apart the tabs (45) of the lower saw blade cover and open the lower saw blade cover (44).
- Remove workpiece fragments and chippings.
- Close the lower saw blade cover (44) again, making sure that the tabs click into place (45).
- Close the base grid (31).
- Bring the power tool into the work position.

##

- Firmly insert a suitable dust extraction hose into the dust extraction adapter (29).

The dust extractor must be suitable for the material being worked.

When extracting dry dust that is especially detrimental to health or carcinogenic, use a special dust extractor.
