5.

Wait for approx. 10 seconds until the message 

“Careful, 

open slowly”

 appears.

6.

Lift the lock of the filling hatch (1) and open the filling hatch slowly 
until horizontal.

If the filling hatch opens quickly from the horizontal position, the 
pneumatic springs (2) are OK.

If the filling hatch does not open from the horizontal position or 
has to be lifted, the pneumatic springs (2) must be replaced.

7.

Close the log wood boiler.

The pneumatic spring inspection is completed.
