Impression cylinder gripper adjustment

I replaced all the impression cylinder grippers on my printmaster 46-2 and can't get enough pressure to hold the sheet, it drops sheets constantly. I put in new springs and grippers but it is not holding tight enough. What is the procedure for getting this right?

you need special tools from heidelberg,for special adjustment
is better that you call service man heidelberg, for fix it
otherwise you will lose your time and money

 

Ok, I loosened the pressure on each spring about 1/2 turn so there was very light grip then starting in the center I loosened the large Allen that holds the finger to the bar and pulling up on that finger slightly re tightened it so there was more pressure. Did this all the way across and then turned each adjustment counter clockwise until it had good grip. It is feeding good now but I have a service call in and they are coming next Tuesday to set the timing and all that.
