Fitting the dust cap and extension (see figure E)

You will need to change the dust cap depending on the drilling diameter:

• Dust cap (3) for a drilling diameter of 4–16 mm
• Dust cap (2) for a drilling diameter of 16–28 mm

In addition, you must change the dust cap if its wall contact surface shows clear signs of wear and is causing dust to escape through the extraction brush during extraction.

Removing the dust cap:

• Press the release button (14) and pull the dust cap upwards out of the holder.

Fitting the dust cap:

• Insert the new dust cap into the holder from above until the release button (14) audibly engages.

The extension (1) is required if you use drill bits with a total length of 165−265 mm.

• Mount and remove the extension (1) according to the assembly/removal of the dust cap.
