What to Check First

  1. If the pre-filter and the large dust separator are not fully assembled, the internal parts may not align properly.
  2. If the dust bin is not assembled in the correct direction (with the lever visible), the charging terminals may not make contact.
  3. If you do not hear a click during assembly, the parts may not be fully locked in place.
  4. 1. Remove the pre-filter and large dust separator Turn the pre-filter and large dust separator as shown in the image and pull them down to remove them.
  5. 2. Remove the dust bin Hold the dust bin and turn it to the left to remove it.
  6. 3. Assemble the pre-filter and large dust separator Insert the crevice tool into the large dust separator and turn it clockwise until it clicks into place.
  7. 4. Assemble the dust bin Align the dust bin in the correct orientation and turn it counterclockwise until it clicks into place.
  8. If you do not hear a 'click' sound, the assembly is incomplete. Be sure to reassemble it before use.
  9. If the dust bin is facing the wrong direction, the lid may not close or the vacuum may not charge.
  10. Always check that the parts are assembled correctly before charging.
