Hi, everyone. Been away for awhile. A local contractor has one of these and no manual for it. No one there knows how to adjust it and he wants me to teach them how. I've slept quite a bit(15 yrs) since I've been around them, LOL!!, and can't remember the clamp jack pressure. I'd be appreciative if someone could tell me.
TIA,
Mike
Hate to say I did go to a class on the ElJays but that was probably 35-40 years ago! So my memory is even worse than yours. I did find this link that is more or less a sales brochure but it does mention the shim adjustment system. Maybe something there will refresh your memory?

A little out take:
Quick Adjustment System
Hydraulic/shim adjustment makes changing the discharge
opening fast and easy. Adjustment is vertical using hydraulic
rams, therefore bowl rotation is not necessary.
This design requires less headroom, less weight and
eliminates the problem of threads jamming with rock dust.
Exact setting is maintained by shim stacks of equal height.
Shims vary in thickness and are color-coded and numbered
for quick recognition. The shims have offset slots for easy
installation and are interlocking.
To tighten the settings, release the clamp ring and raise the
bonnet. Remove shims from the lower stack to establish the
new setting. Removed shims are stored in the upper stack.
The bonnet is then lowered and the clamp ring tightened
hydraulically. Tensioning of clamp bolts is also done hydraulically.
