Maintenance and Cleaning

In order to avoid safety hazards, if the power supply cord needs to be replaced, this must be done by Bosch or by an after-sales service centre that is authorised to repair Bosch power tools.

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

  • Hold the filter cover by the closing flap whilst opening it, and make sure that the opened filter cover clicks into the vertical position. There is a risk of injury if the filter cover falls down.

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

If the flat-pleated filter (34) becomes damaged, replace it immediately.

  • Before each time you clean/replace the flat-pleated filter (34), remove the vacuum hose (30) and insert the sealing plug (23) into the hose adapter (3).
  • Pull on the closing flap (41) and twist the filter cover (40) upwards until it clicks into the vertical position.
  • Hold the flat-pleated filter (34) by the supports and take it out from above.
  • Use a damp cloth to remove any dust and dirt that accrues around the edge of the container (1) when removing the flat-pleated filter (34).
  • The flat-pleated filter can be rinsed out under running water.
  • Insert the cleaned (or a new) flat-pleated filter (34), ensuring that it is positioned correctly and securely.
  • Close the filter cover (40), ensuring you hear it click into place.

  • The pre-filter must not be wet cleaned.
  • Do not reach between the guide handle and the dust extractor from above in order to unlock to pre-filter cover. Otherwise, your hand might get caught.

Pull the guide handle (15) up until the pre-filter cover is freely accessible from the rear.

Press the release button (29) of the pre-filter cover (28) and take it from the pre-filter compartment.

Remove the pre-filter (42).

Brush down the flaps of the pre-filter with a soft brush.

Place the pre-filter into the pre-filter cover (28).

Place the pre-filter cover (28) into the pre-filter compartment and fold it in.

Pull the dust extractor's mains plug from the plug socket.

Remove the top part of the vacuum cleaner (16).

Empty the container (1).

Move the float (44) or gently tap it to remove the dirt.

Clean the floater (44) using a soft cloth.

If necessary, you can also remove the float. To do this, press the locking mechanism (45) and remove the float (44).

Clean the magnet (46) using a brush.

Reinsert the float (44).

Storage

  • Wrap the power cable around the cable holder (24).
  • Insert the accessory into the corresponding brackets.
  • Wrap the vacuum hose (30) into the compartment for the vacuum hose. Pull up both pull straps (17) and hook them into the fastening openings .
  • Click the L-BOXX onto the holders (13).
  • Remove the fleece filter bag as soon as it is full.
  • Only ever carry the dust extractor by the carrying handle (12).
  • To transport the dust extractor, insert the sealing plug (23) into the hose adapter (3).
  • Store the dust extractor on a level surface in a dry room and secure it so that it cannot be used by unauthorised persons.
  • Put the castor brake (22) down to hold the castors (21) in place.

Transport (see figure R)

  • To transport the dust extractor, insert the sealing plug (23) into the hose adapter (3).
  • To make transporting the dust extractor easier and gentler on the back, completely empty the container or dispose of the full fleece filter bag beforehand.
  • Only ever carry the dust extractor by the carrying handle (12).
  • Unlock the castor brake (22) for pushing or pulling the dust extractor.
  • Only use the extended guide handle (15) to push or pull the dust extractor. The dust extractor must not be pulled up steps by the guide handle. The carrying handle must be used in this instance.
  • When carrying the dust extractor up steps, ensure there is nobody directly behind you, in case the dust extractor should unexpectedly fall.
