Where can I find instructions on how to repair a Swingline 270 Heavy Duty electric stapler?”
Hi, Swingline, now owned by ACCO, should have a service manual that would tell you how to clear jams – here’s the url – http://www.acco.com/contactus.aspx#swingline. There is an online discussion about high capacity staplers, including the 270 here: http://lawlibrary.ucdavis.edu/LAWLIB/april01/0059.html – interesting enough, the writer found that a manual stapler made by Acme Stapler Co. worked the best – although the number one model refered to does not appear in Acme’s catalog, this model resembles it: http://www.acmestaple.com/products/model_731.html .
