Maintenance and Cleaning

For the user to carry out maintenance, the dust extractor needs to be disassembled, cleaned and maintained as far as this is possible without endangering maintenance personnel or other persons. Before disassembly, the dust extractor should be cleaned to prevent any potential hazards. The room/enclosure in which the dust extractor is disassembled should be well ventilated. Wear personal protective equipment while carrying out maintenance. After completing maintenance, the maintenance area should be cleaned.
An inspection regarding the dust extraction capability must be carried out at least once a year by the manufacturer or someone who has been trained, e.g. to check for filter damage, that the dust extractor is tight and that the control unit is functioning correctly.
Class L dust extractors which were located in dirty environments should have their exteriors, as well as all their components, cleaned or treated with sealant. When performing maintenance and repair work, all dirty parts that cannot be cleaned satisfactorily must be disposed of. Such parts must be disposed of in impermeable bags in accordance with the valid provisions for disposing of such waste.

Clean the container (1) after each use in order to ensure that the dust extractor continues to perform optimally.

  • Open the catches (2) and remove the dust extractor lid (5).
  • Shake out the container (1) over a suitable waste bin.
  • If necessary, clean the container with a damp cloth.
    Clean the filter if required see Cleaning/replacing filters (see figures I1–I2).
  • Replace the dust extractor lid (5) and close the catches (2).

Suction power is dependent on the condition of the filter. Therefore, the filter should be cleaned regularly.

Replace any damaged filters immediately.

  • Open the catches (2) and remove the dust extractor lid (5).
  • Turn the filter (33) as far as it will go in the direction of rotation and remove it from the filter bracket (35).
  • If the filter is dry:
    Tap the filter (33) on the side of a suitable waste bin. When doing so, ensure that you do not damage the flaps on the filter.
    To achieve maximum suction power, brush down the flaps of the filter using a soft brush.
    or
    If the filter is wet:
    Rinse the filter (33) under running water and then leave it to dry thoroughly.
    or
    Replace the filter (33) if it is damaged.
  • Position the filter (33) over the filter bracket (35) and turn it as far as it will go in the direction of rotation .
  • Replace the dust extractor lid (5) and close the catches (2).
    Make sure that the catches engage firmly.

If the suction power is insufficient, check:

Regularly emptying the container (1) and cleaning the filter (33) will ensure optimum suction power.
If suction power is not achieved after that, the dust extractor should be sent to the after-sales service.

  • Insert the suction tubes (18) into the brackets (25).
  • Insert the crevice nozzle (16) into a suction tube (18).
  • Insert the floor nozzle (17) into the bracket (27).
  • Wind the vacuum hose (13) around the bracket (27) from below and fasten the retaining strap (36).
  • Only ever carry the dust extractor by the carrying handle (6) or by the carrying strap (if present).
  • Store the dust extractor in a dry room and secure it so that it cannot be used by unauthorised persons.
