Hydraulic paper cutter and the bleeding of lines? Triumph 5551

[ART INK]

We have just replaced the slave piston in our Triumph 5551 paper cutter (leaking). While finishing up the job, we noticed that there is no place to bleed the line of air. For the life of us, we cannot find any reference (or nipple) to bleed the line of air. Do these cutters need to be bled? How can any hydraulic system not have a system (process) to bleed the lines? Our pressure is below the max, and wonder if there is air in the lines. Can anyone help us understand how to bleed this (or similar) cutter?

If you think you have air in the lines you could back off (until fluid leaks) one of the hose fittings that will allow you to catch the hydraulic fluid as you bleed the lines. Or you could take it apart and make sure you fill all the lines and new cylinder with fluid. Small amounts of air should eventually make it's way back to the reservoir. Power OFF and under NO pressure while doing this.

I was told moden cutter is designed with self bleeding feature, no need to do this kind job yourself
