    I have a 1997 SM74 and the feeder is out of time. for the most part it runs but the speed adjustment of the belts is set to 100. What degree is the timimg suppose to be set at. and do you adjust it on the feeder or like the 102 that we have on the drive side.

    Sheet should arrive at the head stops at 300 degrees. before you set your feeder timing make sure you have your feeder head timing set right too. Yes, on the drive side there is an adjustment sprocket similar to the one on your 102.

    Also set the press at medium gripper bite 9mm before adjusting the feeder timing.
