When sticky materials are treated, check for possible clogging along the hose, in the inlet and on the ba󰀪e plate inside the ltering chamber. To clean, scrape the inlet (2) from the outside to remove deposits. Filtering chamber gasket check for machines equipped with dust container Figure 16 If the gasket (1) between the container and the ltering chamber (3) fails to guarantee sealing: ■ Loosen the four screws (2) that lock the ltering chamber (3) against the vacuum cleaner structure. ■ Allow the ltering chamber (3) to lower down and tighten the screws (2) once it has reached the sealing position. If an optimal seal is not yet obtained or if there are tears, cracks, etc., the gasket must be replaced.C447 16
