Start-up

The dust extractor may be used for vacuuming and extracting the following materials:

The dust extractor must categorically not be used in potentially explosive areas.

To ensure optimum suction power, you must always fully unwind the vacuum hose (33) from the top part of the dust extractor (16).

You can adjust the suction power to a continuously variable degree using the suction power regulator (11).

Set the suction power regulator (11) to maximum suction power when completing applications that generate a high level of dust.

Set the suction power regulator (11) to the reduced suction power position when completing applications that generate a low level of dust, and also to regulate the suction between the connected power tool and the surface of the workpiece (e.g. when sanding).

The dust extractor is fitted with volume flow monitoring. In the "extraction" operating mode, the volume flow monitoring is fixed to a value of 20 m/s.
If the value falls below this, e.g. due to accumulated dirt in the vacuum hose, a full fleece filter bag or a clogged flat-pleated filter, one of the LED indicators (7) 22 or 28 will flash and an audible alarm signal will sound. If this happens, switch off the dust extractor and check it as described in the "Rectifying faults" section.

Note: When working with power tools that have a low air feed into the vacuum hose (e.g. jigsaws, sanders, etc.), an audible alarm signal may sound. To avoid the warning message, it is recommended that you also use a suitable dust extraction adapter with a false air intake from the range of accessories.

To regulate the suction power, select the hose diameter used.

Press the vacuum hose diameter button (8). LED indicator (7) 22 or 28 will light up.

  • Observe the permitted connected load of the plug socket on the dust extractor. Exceeding the maximum permitted connected load can cause the dust extractor to be overloaded. The motor protection device will be triggered. Send the dust extractor to an authorised Bosch after-sales service centre.

The plug socket for power tools (4) is live as soon as the mains plug of the dust extractor is plugged into the socket and the main switch is in position 1. It can be used as an external power connection on the dust extractor, e.g. when working with extraction systems. In position 1+, the automatic start/stop feature of the dust extractor is activated. The dust extractor can be switched on remotely via the connected power tool.
