No idea if itís normal for that machine.

But probably all you can do is check the servo pressure is correct and make sure the servo filter/filters have been changed. And possibly that the servo accumulator is still functioning, although I donít think this would cause heavy operation if it were not doing its job, but worth a try, you never know.

Had the same thing on my machine after a couple of thousand hours, just a slight adjustment of the servo pressure cured it, it's something you can do yourself and only takes a coupe of minutes.

If I could upload pics🤔 I'd show you what it looks like on my machine, there's basically a 22mm dust cap that you take off to reveal a locking nut, locking off an alan key adjuster, slacken the locking nut, then just unscrew it a fraction of a turn then lock it back off again, and see if that makes any difference, it is only a fraction at a time, you'll know if it's to much cos they will be really light, it's just a case fine tuning it to how it suits you.

the pressure relief valve will probably be on the servo circuit control solenoid valve block - feeds your servo circuit with pressure and is controlled by the dead man switch ... should look pretty much like most other PRVs .. setting screw with a lock nut securing it and maybe a cover over it
