Caution! cover the intake ducts with a clean cloth so that foreign bodies do not get into the inlet ducts. Upon refitting and before placing the filter box cover, make sure neither the cloth nor any other object has been left inside the filter box. Make sure the filtering element is correctly placed so that unfiltered air does not flow in. Do not forget that early wear of the piston rings and the cylinder can be caused by a malfunctioning or misplaced filtering element.
