# 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.

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

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.

## Self-generated dust extraction (see figure C)

For basic chip collection, use a dust bag (46) (accessory).

- Attach the dust bag (46) to the chip ejector (37).

During sawing, the dust bag must not come into contact with moving tool components.

Always empty the dust bag in good time.

- Check and clean the dust bag each time after using.

- When sawing aluminium, remove the dust bag to avoid the risk of fire.

## External Dust Extraction

You can also attach a dust extraction hose (35 mm diameter) to the chip ejector (37) for extraction.

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.
