Along with all the welcome aboard posts here is one you can take to heart. Don't make a move without the pubs: operators' manual, organizational maintenance manual and parts book, and lubrication order. The relevant pubs are TMs 9-2320-260-10, 20, 20P, and 260 LO. There are about 40ea grease fittings on an M813, 4ea on the handbrake alone. Neglect them at your own peril. Make sure you figure out how to operate the cold weather starting aid and prime the fuel system if you are clumsy enough to run out of fuel. The TMs are available to download on this site or you could get paper copies at swap meets or on line.
