Good afternoon, I have recently started at a printing company as a maintenance supervisor. I am in the process of drawing up maintenance schedules for our machines, but most of the equipment does not have any documents attached. I am hoping there are guys on here that can help me out. Below listed are the machines that I need maintenance instructions for: Stahl folder KC78/4 (1993) Didde 176-774 Heidelberg SM102-5-p4 (1996) Polar 115 CE&EL (1969&1973) Ryobi 924 (2011) Your assistance would be appreciated.
