I have a 1995 Vermeer 1250 that is stored outside. The last couple of days it has been cold (0 degrees) and the chipper has been starting difficultly. The battery is brand new and the machine was recently reconditioned, so it should be in fairly good shape. When we start the chipper in the cold, the battery doesnt have enough power to start the machine. We have been jumping the chipper off of our pickup truck. I am wondering if anyone has any tips on making this chipper start easier when it is cold out? After the initial start, the chipper runs fine and restarts fine. The only issue we are having is with the initial start up. By the way it is a Perkins diesel engine.... 86hp.
