Purge of an insert of the air filter

Through each 15 000 km or annually we recommend to clear a paper insert of the filter of large particles of dust. At a trip on very dusty roads this interval can be reduced before daily cleaning.


  1. Dismantle a paper insert of the filter as it is described above.
  2. Beat out the filter about a firm surface to separate rough particles of dirt.
  3. If it is necessary to remove a fine dust, it is necessary to blow sideways filter plates compressed air. Never direct a stream of compressed air directly on filter paper! Otherwise the part of grains of dust will strongly be pressed into a filter time.
  4. Wipe the filter case a pure rag.
  5. Again mount the filter.
