Jumper Cables Keep cable clamps from touching after the first terminal is clamped. Follow the diagram for the proper order to connect the two batteries. Start with Clamp 1 and end with Clamp 4. After these connections have been made, start the vehicle that has the good battery first, then start the stalled vehicle. Always wear a pair of splash-proof goggles.
Batteries contain hydrogen and oxygen, two flammable and explosive gasses.
Never smoke or operate anything that may cause a spark when working on a battery. The gasses may ignite and cause the battery to explode. Check your battery for damage such as cracks, corrosive materials and loose wires. Dispose of batteries properly. The tractor by all means is the workhorse around the farm.
