6.5 Vacuum Pump Filter Element
Point
Air drawn into the pump should be clean. The filter element should therefore be
replaced when it becomes excessively dirty.

extracting the filter case, replace the filter element.
WARNING
• Turn the main power off before performing this procedure.
• Do not touch the vacuum pump immediately after operation
because it may be extremely hot. Allow the pump to cool before
beginning this procedure.
