9.8 DAMPERS, FLEXIBLE ELEMENTS

Operable damper blades must be locked to prevent spontaneous or accidental closure. Never
put your fingers between the blades of an open damper as this is a serious injury hazard!
Check for dirt and grime, and any damage, and inspect the movement of the damper blades,
and the proper closure of the damper in particular. Vacuum up any dust and then wipe down
the surfaces of the damper blades using a damp rag. The plastic gears on dampers are
manufactured from a material that does not require subsequent lubrication. Use a lubricating
spray on the lever mechanism on those dampers with lubricated lever mechanisms. If a flexible
cuff is installed downstream of the damper, inspect it to ensure a proper seal and its integrity,
or clean if needed.
