Need a little help with the WO FLT120

[Fms50]

I’m not sure which screws to remove on the focuser to remove the coarse knob to install an eaf. My other refractors have exposed lock screws but the FLT120 has them hidden. I’m afraid if I back out the wrong ones will mess it up. Any help will be appreciated. Thanks
