Using Jumper Cables SAFETY When using jumper cables to start the machine, attach the positive (+) jumper first then the negative (-) jumper last to a remote location on the chassis, as shown in the following figure. For additional information, see “Starting Engine With Booster Cable” on page 2-178.. Starting the Machine Never try to start the machine by tampering or shorting the starter terminals. Accidental movements of the machine could cause injury or even death. Always start the machine while seated in the operator’s cab using the ignition switch. Never use a welder or a machine with a higher voltage system to jump-start the machine.
Using a higher voltage to jump-start a machine may damage the machine’s electrical system or cause an unexpected explosion or fire. Always jump-start a machine with one of equal voltage. Never allow the machines to touch each other when jump-starting a machine. WA380-6 1-41
