Inspecting the fan.
The maintenance tasks pertaining to inspections to be
performed regularly are described in this chapter.
All maintenance tasks must be performed with the
impeller at a complete standstill. Re-lubrication tasks
for the bearings and for the shaft seal, however, are
an exception to this rule.
DANGER
Fan openings and rotating parts!
Fatalities or extremely serious injuries as a result of ejected
parts and seizing of body parts and clothing.
→ Switch off the fan.
→ Wait until the impeller comes to a complete standstill.
→ Only remove the covers of the fan openings when the
impeller is at a complete standstill.
→ Only remove the protective hoods of rotating parts
when the impeller is at a complete standstill.
NOTICE!
Ensure that the fan remains accessible for all
inspections, maintenance tasks and repairs.
