Using Booster Cables SAFETY If any mistake is made in the method of connecting the booster cables, it may cause the battery to explode. Read all battery “Hazards” on page 1-46. Always heed the following precautions: Wear safety goggles and rubber gloves when starting the engine with booster cables. When connecting a normal machine to a problem machine with booster cables, always use a normal machine with the same battery voltage as the problem machine. Do not allow the two machines to touch. When starting with a booster cable, carry out the starting operation with two workers (one worker sitting in the operator’s seat and the other working with the battery).
When connecting the booster cables, turn the starting switch to the OFF position for both the normal machine and problem machine. There is a danger that the machine will move when the power is connected. When using booster 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 Cables” on page 2-183. When removing the booster cables, be careful not to let the booster cable clips touch each other or to let the clips touch the machine.
Starting the Machine with Booster Cables Never try to start the machine by tampering or jumping across the starter terminals. Accidental movements of the machine could cause injury or even death. Always use the starting switch key to start the machine while you are seated in the operator’s cab. 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. WA430-6 1-47
