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 M dust extractors that have been in dirty environments should have their exteriors, as well as all their components, cleaned. Suction, wipe down and seal the outside of the dust extractor before removing it from the danger zone. 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.

Wipe the container (12) from time to time using a non-abrasive off-the-shelf cleaning product and leave it to dry.

The 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 (13) and remove the dust extractor lid (15).
  • Take hold of the main filter (32) at the end piece (not at the flaps). Turn it as far as it will go in the rotational direction and then remove it (see figure M).
  • If the filter is dry:
    Tap the main filter (32) 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 main filter (32) under running water and then leave it to dry thoroughly.
    or
    Replace the main filter (32) if it is damaged.
  • Place the main filter (32) over the float cage (34) and turn it as far as it will go in the rotational direction  into the filter holder (35) (see figure B).
  • Replace the dust extractor lid (15) and close the catches (13).
    Make sure that the catches engage firmly.

Only use rollers as per EN 12529 (diameter of fastening pin 11 mm).

  • Check the functionality of the castor brakes before using the dust extractor.

Use the brakes if you want the dust extractor to remain stationary.

You can cut off a section of a vacuum hose (20) that is defective and continue to use the undamaged section.

  • Wear gloves when repairing the hose. This poses a risk of injury.

To repair the vacuum hose at the dust extractor side (see figures O−P):

  • Loosen the locking ring (49) from the hose connector (47) by pushing in the retaining lugs with a screwdriver.
  • Pull the locking ring (49) behind the defective area ➊.
  • Unscrew the sealing sleeve (48) ➋.
  • Cut off the vacuum hose (20) behind the defective area (see figure P).
  • Screw the sealing sleeve (48) back on ➌.
  • Push the end of the vacuum house into the hose connector (47) ➍.
  • Push the locking ring (49) onto the hose connector (47) until it clicks audibly into place ➎.

To carry out a repair at the power tool/nozzle side (see figure Q):

  • Unscrew the sealing sleeve (50) ➊.
  • Cut off the vacuum hose (20) behind the defective area ➋.
  • Screw the sealing sleeve (50) back on ➌.

If the detents (43) for the bag holder (33) are damaged, the bag holder can also be permanently screwed to the top part of the dust extractor with commercially available Phillips P4 11 mm screws. If the bag holder (33) is in contact with the spring (51), the conductivity for the electrostatic discharge is retained.
