Dust/Chip Extraction
Do not perform work without taking dust-reducing measures. Using a suitable dust extraction attachment will reduce exposure to harmful dust. Provide good ventilation at the workplace. Always use suitable breathing protection. Use a dust extraction system that is suitable for the material wherever possible. The regulations on the materials being machined that apply in the country of use must be observed.
- Avoid dust accumulation at the workplace. Dust can easily ignite.

Refer to the dust extractor’s instructions. If there is reduced suction power, stop working and eliminate the cause.
External Dust Extraction (see figure B)
The extraction outlet (2) can turn freely.
Connect an extraction hose (30) (accessory) to the extraction outlet (2). Connect the extraction hose (30) to a dust extractor (accessory). You will find an overview of how to connect to various dust extractors at the end of these operating instructions.
We recommend using anti-static hoses and dust extractors. Whilst it is possible to use standard hoses and dust extractors, this is not recommended due to a potential static charge accumulation.
Use a dust extractor for dust class M or H. We recommend wearing a dust mask. Mineral dust is hazardous to health and can cause cancer.
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.
Instructions for the use of wall chasers
Please observe the following notes in order to reduce the dust emissions occurring while working.
- Only use wall chasers and dust extractors of dust class M or H in a combination recommended by Bosch. Other combinations may lead to worse collection and separation of dust.
- Observe the operating instructions of the for maintenance and cleaning of the dust extractor, including the filter. Empty dust collection containers immediately once full. Clean the dust extractor filters regularly and always insert the filters completely into the dust extractor.
- Only use the extraction hoses intended by Bosch. Do not manipulate the extraction hose. If pieces of rock are drawn into the extraction hose, stop working and clean the extraction hose immediately. Prevent the extraction hose from being bent or creased.
- Only use the wall chaser for its intended purpose.
- Only use application tools that are sharp and in perfect condition. A noticeable slowdown in work progress is a sign of worn application tools.
- Observe the general requirements for construction site workplaces.
- Ensure good ventilation.
- Ensure that the working area is free of obstructions. For longer grooves, the dust extractor must follow behind without delay and without obstruction.
- Wear hearing protection, protective goggles, dust mask and gloves as required. Use at least an FFP 2 protection class particle-filtering half mask.
- Use a suitable vacuum cleaner for cleaning the workplace. Prevent settled dust from being swirled up by sweeping.
