Functionally these two units are the same. However, model 6110 sold at Lowe's stores includes a 20' power cord.
New hour meter instructions have been added to the manual; there was an error in the manual when it was first printed. This has been resolved and the updated manuals are now available on our website:
• 5939 owner's manual - http://goo.gl/EB58B
• 6110 owner's manual - http://goo.gl/TWtkT
If you continue to have issues with your hourmeter, please call 888-GENERAC and our customer support team will be able to work with you to resolve this issue.
