    We have a fairly old Cassese underpinner - CS89 , that has stopped functioning correctly and needs service and repair. Does anyone know of some one in the Vancouver area that can do this? We could also crate and ship to have it fixed...
    Hoping for good news...
    Thanks, Karen

    You could try calling Active Sales.
    But, what's wrong? maybe we could walk you through the repair?

    I had two underpinners just like yours fixed by John Metzdorff at LJ Minneapolis warehouse.
    I've been using one for a few month without any problem and second is my backup.
    952-932-9117 his phone number.

    You can try looking up some local pneumatic repair shops in the area. Even guys who know air compressors are a possible call.

    If you're up for it, maybe take a video, upload to YouTube or something and link to us here. Maybe we can help you through it. I had a CS-89 that gave me some problems that I was able to fix myself. They're really not complicated units, however if you don't have time, then you don't have time!

    We have model CS89, approx 10 years old, the machine will shoot a pin, but then does not recoil, the air must be turned off, then the hammer drops. Does this make any sense to you? Do you have any advice?
    Thanks so much…

    There is a limit switch on a block on the right hand side as you stand behind the machine.
    It looks like a button on the bottom of a rectangular block. Air hoses go to the block. It is attached to the machine with four Allen bolts. It is either loose or out of alignment. Tighten those bolts and make sure the button gets hit when the hammer comes up.

    I will reply tomorrow with a full teardown and reassembly for you. I just got in but am about to head back out. I apologize for the delay, but I have an extra block should you require. Heck I have a complete machine sitting in my garage waiting for the one in my shop to die! =D Worst case scenario, there's one available for you.

    Give me 3/4 of a day and I'll have more info for ya!
