    Merlo 40.9 MF weird hydraulic problem

    Hi Guys, I've got a 40.9 MF with only 300hrs on it. I'm from Australia and the service and support is almost non existent from the Merlo Australia. My problem is, sometimes when the 3pl is lower then 100% in height, the crowd on the front Boom stops working, the Boom retract in slows down, chasis tilt slows down, the power steering is harder to use. Few other things I think is related is there's a hydraulic squealing noise when use 3pl and there's a little valve block on side of cab that looks like a breather leaks oil. If i put the 3 pl all the way to the top(100%) it all works fine.

    Any ideas??

    Edit- Hope you don't mind but I have moved your maiden post from the old thread you had added it to so that it has its own thread and hopefully gets spotted easier. (sorry but my experience of merlos is pretty non-existent, hopefully someone may have an idea)
