Semi-Automatic Paper Cutter Adjustment

I recently purchased a multigraph paper cutter, model 130. It has a hydraulic motor that drives the clamp and knife.

I just got the knife sharpened, and have been trying to adjust it to cut evenly. During my troubleshooting, I’ve found that the clamp pressure is uneven, and the left side leads the right, which means that the knife cuts unevenly, even though I’ve adjusted the knife relative to the bed.

Unfortunately, I can’t find a reference or service manual, or anything on line about the cutter. It works fine, it cuts straight, and the uneven cut can be worked around with additional packing sheets, but it bothers my engineering sense to know it’s not quite right.

I started to loosen some bolts holding the case together to get a look at the mechanism, but it’s spring loaded, and without a manual, I’m hesitant to go further.

Does anyone have a service manual, or some hints?

Thanks much,
