Hello all;

I'm getting ready to try UT-7 LK in the LK position of my 7600 in an 
attempt to get a neutral 2-ink scale; I still haven't figured out how 
to get the dampers of this machine so I can do a quicker change-over,  
can any one either point me to a service manual pdf, or describe (off-
list if need be) how to get the hold-down bar of the head?

Thanks
