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.

- A)
Power value at the power tool’s dust extractor connection
- B)
According to IEC/EN 60335-2-69
Refer to the dust extractor’s instructions. If there is reduced suction power, stop working and eliminate the cause.
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.
- To prevent the risk of fire when sawing aluminium, empty the lower saw blade cover and do not use chip extraction.
Cleaning the lower saw blade cover (see figure j)
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.
External dust extraction (see figure k)
- 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.
