Collimating Skywatcher 130M

hi
I have looking at collimating my telecope.
It seems staright forward enough, however when it comes to adjusting the mirror at the opening of the telescope (the secondary mirror i think) there is only the central screw to adjust, to loosen this mirror. Am i right in thinking there should be three small screws to allow fine adjustment. The holes for them are there but nothing to adjust. Its a Skywatcher 130m

Thanks

Hi
Instead of collimating screws for the secondary..
SkyWatcher have small allen bolts, deep down in those 3 holes
1.5mm or 2mm allen key required IIRC
