It also said to loosen the actuator mounting bolts, apply 60 psi to the actuator, then remove the bolts and remove the actuator.

So, unless there’s another way, I don’t have a way to hook up shop air to the actuator yet

All a person needs is a blo-gun with rubber tip to relieve the spring force when installing it or removing it. 20-25 psi is all it typically takes to relieve most if not all the spring force.

Although it is much easier with air on it, the actuator can also be muscled in place (against its spring force) without any air on it at all. It can also be removed by working it loose with a screw driver (once the bolts + snap-ring on arm are removed). It will pop up about maybe 1/8 inch or so (rough guess) with some force (because it is spring loaded) as it lets go but it does not hurt it. Better to use a bit of shop air and a blo-gun on (while installing or removing) it though if you have access to it.
