5.1.1 Maintenance
WARNING! Risk of personal injury.
Always use an approved breathing mask when carrying out work that may involve exposure to
dust.
Check the back-flush valve regularly. The valve disc is situated in the silencer, where it can be
seen through the grille. During normal operation, the disk is lifted by the discharge air. When
the appliance is at rest or if the direction of rotation is incorrect, the disc is depressed against
the seat preventing particles from entering.
Check the starter, re-tighten cable connections. Replace damaged electrical components and
visually inspect cable(s).
