Here's my note to myself last year, see if it still works. This should get you the info on you machine as it was shipped from the factory. --- Updated June 2018: Let's see if I can get this right
Go to Bobcat website www.bobcat.com Upper left hand corner, open "our company". A second "our company" choice will appear, also on upper left hand side. Open the pull-down and select "Help Center". Major heading FAQ should appear. Second menu choice is "serial number". You take it from there..... --- I suspect the Bobcat dealer will be glad to swap you a manual for a peek in you wallet. Ebay is another source. There are a bunch on-line. Try here: https://truckmanualshub.com/bobcat-pdf-workshop-manuals/ I see a 753 manual listed. Looks like they're free. Enjoy that machine!
