Silvey SDM-4 Advice

[Frontcut]

Is there anyone on this forum who knows how to adjust the rails on the SDM-4 grinder? mine is currently set up for .063 gauge chain and im moving to .058. I know there is shims inside but was hoping for advice before i take it apart and wreck the whole machine.

Thanks in advance

Thanks, Ive looked through there plenty of times and anywhere else i could think of. Was hoping for some advice from someone who has serviced the machines

I have one and use it to sharpen .050 and .063 chain and never adjust it for a change in gauge.
