Emptying the Dust Box (see figures F1−F2)

Note: Wear a dust mask when performing maintenance and cleaning on the dust box.

Empty the dust box (13) regularly as well as after completing your work, in order to ensure that the dust extraction attachment continues to perform optimally. The viewing window (7) enables you to check how full the dust box is.

• Hold the power tool with the dust extraction attachment horizontally and switch on the power tool for a few seconds.
  This will cause residual dust to be sucked out of the extraction channel into the dust box (13).
• Press both the left-hand and right-hand release buttons (6) and pull the dust box (13) out of the dust extraction attachment.
• If necessary, take the HEPA filter (14) out of the dust box and carefully tap it out or brush down the filter flaps with a soft brush.
  Note: Do not clean the HEPA filter with water and do not use compressed air to blow it clean.
• Shake out the dust box (13) over a suitable waste bin.
• Put the HEPA filter (14) back in the dust box (13) after cleaning it. Then slide the dust box into the dust extraction attachment until the release buttons (6) audibly engage.
