Cassese underpinner service and repairs

    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!

    YES! This first. =)

    Will check in before I do a teardown of the part tomorrow.

    Help!! I'm having a similar issue! CS 89, the boom takes forever to raise...I've tightened the limit switch and have tried to reset the pin, but nothing seems to work....just bought this machine used, but stated it was in good working condition. I'd appreciate any tips on what I can try next....new shop, opening in 2 weeks...yikes!

    You might try to contact Active Sales if they have a tech support or even Google your model.

    We have a Cassese but it's a different model, a CS299.
    I know our machine but not yours.
    Good luck with your issue.

    Active Sales, or Larson Tech support are good resources.
    "Takes forever to raise" doesn't sound like a limit switch issue.
    If the limit switch isn't right it STAYS down until you hit the air release. (At least it always has for me.)
    Is the nail firing and embedding itself completely?
    So, you get it setup, then, you step on the pedal and it fires properly, you take your foot off the pedal, and it stays down?
    Sounds more like the air isn't releasing properly. Never had that happen. But, if that describes the behavior accurately, I'd be looking for kinked, or bent hoses maybe?
    Does it release and pop up if you hit the big red button on the side?

    The nail is firing properly, the red button does release it. Just very slowly. Today, the boom stays down completely until I hit the button. I didn't notice yesterday but the horizontal clamp is not engaging when I press the foot pedal halfway...I don't have a schematic for air lines, but shouldn't that be hooked up to the pedal? There is nothing connecting it....If anyone could send me a picture of how that is hooked up, that would give me a place to start. I also hear air coming out of the pedal. I'm so close to making this thing work, truly appreciate your input! Will also try tech support!

    Update...the 3 hoses coming off the foot pedal are all tape together, and the one that is supposed to go to horizontal lock is taped off. Tried reconnecting it, but still doesn't engage lock when pedal is pressed halfway. And the sellers are not the users, so they can't tell me much. Looks like a service call is in order!

    Here's a couple of pictures of my hoses.
    (Mine's still for sale if anyone is interested? $700)

    In hopes to save a few hundred dollars, remove only one hose from the foot pedal and airbox under the "shelf" and try calling a few local trades stores who deal in pneumatics with dimensions of your hose diameter, inside and out. Hopefully they can help you out or point you in the right direction. Might take a few calls, but can be worth it to try replacing hoses one by one. At least then you'll get to know your machine, and if that doesn't work you won't have to replace hoses later!

    Let me know if you need parts. I have most parts to make up a full new machine. Already sitting on a working spare and looking to purge my hoardings! Trying to be more like @Gumby and live on a boat! o_O

    Hi all. I also have a recently purchased, used CS89. It doesn't look like all the pneumatics are present, but I'm unsure. Would anyone mind posting pictures of your hose connections so I could compare?
    This part in particular appears to be missing a fitting or valve.

    Here's a pic of my unit. Where you've circled, mine looks the same. The threaded end with nothing coming out of it is supposed to be that way.

    If you need any other pics, let me know. Happy to help.

    Just last week I had to repair two Cassese underpinners; a CS 299 Ultra (new in 2000) and a CS299M Ultra (new in 2005). I have very limited experience with troubled underpinners, because I've always kept mine clean and supplied them clean dry, lubricated air. And I have even less experience with Cassese machines (I've used Italian AMP/MitreMite and Pilm machines for 30 years), so I was unsure what to do.

    With some poking around and two phone calls to Jon at Active Sales, I was able to get them both working well. I highly recommend Jon. He's apparently accustomed to talking with framers about "thingamajigs" and "whatchamacallits", because he seemed to know exactly what I was asking about, and told me precisely what to do. :)

    Yes.
    I am more familiar with the AMP Miter Mites and I've repaired them and rebuilt parts in the past.

    We have 2 Cassese 299s now at work and I'm learning about them as I go.
    I've done a number of repairs, replacing the spring that pushes the v-nails, and a few other repairs.
    What I recently learned is that the 299 has a water condensation purge built into the on/off air valve.;)

    Looks like we have some things in common. The Cassese machines were not very difficult to repair, but now a present client has a VN-4 automatic underpinner that is in terrible shape, and wonders if it might be worth restoration as a manual machine. The AMP service center has guessed that it would cost $1500 or-so for them to do it, which is more than this client will spend to recondition the machine as a spare.

    I have no experience with the pneumatic circuitry of these machines, since all of mine have functioned well for as long as I've had them. Since you have some knowledge, could you comment about how hard it would be to convert and recondition this older VN-4 as a manual machine? If I could do it for the cost of parts and roughly 10 hours of work, he might go for it.

    Opinions would be appreciated.

    Found some PDFs (One and two) for you to browse over Jim. Hopefully it will show you the breakdown of your machine, even if it's not the exact same, the similarities should help get a good idea of what goes where, possible part numbers, and if your friend is bent on getting it to manual, the possibilities of that.

    I don't have much experience working with pneumatics, but I've hacked my way through the troubles I've had so far with the machines I have. Keep'em oiled up fellas and fillas!

    Thanks, Aaron. I appreciate the instruction manuals. If I can talk the owner into getting this machine going again, your information will be very helpful.
