# 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 extraction adapter (23) can be fitted to the front or the back using the hose connection.

When the guide-bushing adapter (34) is inserted, the guide-bushing adapter may need to be rotated 180° so that the extraction adapter (23) does not touch the release lever (36).

Fasten the dust extraction adapter (23) to the base plate (5) using the two knurled screws (24).

To ensure optimum extraction, the dust extraction adapter (23) must be cleaned regularly.

The dust extraction adapter (26) can be fitted to the front or the back using the hose connection.

When the guide-bushing adapter (34) is inserted, fasten the extraction adapter (26) to the base plate (5) using the two knurled screws (24). For applications without the guide-bushing adapter (34), firstly mount the intermediate ring (27) to the extraction adapter (26) as shown in the figure.

Attach an extraction hose (dia. 35 mm) (25) (accessory) to the fitted dust extraction adapter. Connect the dust extraction hose (25) to a dust extractor (accessory).

The power tool can be directly connected to the plug socket of a Bosch all-purpose dust extractor with remote starter. This dust extractor is started up automatically when the power tool is switched on.

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

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