Phil, One beautiful machine! (I also have a 3520 and love it!) Now far be it from this Canuck to lecture on safety, (but been there, done that and seen some terrible accidents!)
Please, please Phil,....don't ever,.."EVER" trust hydraulics,..no matter how new or no matter how locked !!!!!! If you must work under a raised loader or any other hydraulic item,.....for heaven sake, put a prop under it!!! You may get away with it for years,...but then,..it only takes "once" to end it!
Sorry to be the one to sour a happy day,...but my intention was to ensure the happy days continue!
Such a pleasure to hear from France.
Bon jour,
