Just write to Tru-Cut and include your serial number. They will mail a manual to you.

Thanks Bill, My saw runs fine in vertical position. If I pivot it to the right (with the bar on the bottom) The way you'd usually cut through a tree, it dies when I start cutting. If I turn it the other way (with bar up and gas/oil fill on bottom) it runs okay. I've had it for years and have virtually no maintenance problems. Maybe that Is the problem. It needs a little maintenance

Sure. You will need the build/model # rather than the number you have.It would be like a 13a-XXXXXXX. Here is a link that might be useful: MTD

I had the larger 20hp Kohler 50" deck version of that Scotts by Murray from Home Depot. I have a manual for that model and looked at the "diagnostic dash" as they call it. There are warning lights on the left and right for various things but the LCD only shows hours and there is no mention of error codes. I never saw anything on the LCD except hours. If the LCD is showing scrambled letters or numbers perhaps it got a static hit. Disconnect the ground terminal of the battery and let it sit overnight. Hook the battery cable back up in the morning and see what it shows. It will remember the hours if it is working correctly. Another possibility, if the connections of the LCD at the circuit board are damaged, shorted, wet, or corroded the display can go nuts. If you remove the diagnostic dash and look carefully it can be disassembled and cleaned. If you want the manual let me know and we can work something out.
