Batteries give off flammable fumes that can explode resulting in personal injury.
Prevent sparks near the batteries. They could cause vapors to explode. Do not allow the jump start cable ends to contact each other or the machine.
Do not smoke when checking battery electrolyte levels.
Electrolyte is an acid and can cause personal injury if it contacts skin or eyes.
Always wear eye protection when starting a machine with jump start cables.
Improper jump start procedures can cause an explosion resulting in personal injury.
Always connect the positive (+) to positive (+) and the negative (-) to negative (-).
Jump start only with an energy source with the same voltage as the stalled machine. Turn off all lights and accessories on the stalled machine.
Otherwise, they will operate when the energy source is connected.

To prevent damage to engine bearings and to electrical circuits when you jump start a machine, do not allow the stalled machine to touch the machine that is used as the electrical source. Severely discharged maintenance free batteries do not fully recharge from the alternator after jump starting. The batteries must be charged to proper voltage with a battery charger. Many batteries thought to be unusable are still rechargeable. This machine has a 12 volt starting system. Use only the same voltage for jump starting. Use of a welder or higher voltage damages the electrical system. Refer to Special Instruction, Battery Test Procedure, SEHS7633, available from your Caterpillar dealer, for complete testing and charging information.

1. Determine the reason that the engine will not crank. If equipped with the auxiliary hydraulic electronic control module, the Caterpillar(r) ET can be used to aid in troubleshooting.
2. Engage the parking brake. Lower the work tools to the ground. If necessary, refer to Operation and Maintenance Manual, "Equipment Lowering with Engine Stopped". Move all control levers to the HOLD or NEUTRAL position.
3. Turn the engine start switch to the OFF position. Turn off all accessories.
4. Move the machine that is being used as an electrical source near the stalled machine in order that the jump start cables can reach the stalled machine. DO NOT ALLOW THE MACHINES TO CONTACT EACH OTHER.
5. Stop the engine on the machine that is being used as an electrical source. If an auxiliary power source is being used, turn off the charging system.
6. Ensure that the battery caps on both machines are tight and correctly placed. Ensure that the batteries in the stalled machine are not frozen.
7. Connect the positive jump start cable to the positive terminal on the discharged battery.
Do not allow the positive cable clamps to contact any metal except for the battery terminals.
8. Connect the other positive end of the jump start cable to the positive terminal of the electrical source.
9. Connect the negative jump start cable to the negative terminal of the electrical source.
10. Connect the other negative end of the jump start cable to the engine block or to the frame of the stalled machine. Do not make this connection to the battery post. Do not allow the jump start cables to contact the battery cables, the fuel lines, the hydraulic lines, or any moving parts.
11. Start the engine of the machine that is being used as an electrical source or energize the charging system for the auxiliary power source.
12. Wait at least two minutes before attempting to start the stalled machine. This will allow the batteries in the stalled machine to partially charge.
13. Attempt to start the stalled engine. See Operation and Maintenance Manual, "Starting the Engine" for the correct starting procedure.
14. After the stalled engine starts, disconnect the negative jump start cable from the stalled machine.
15. Disconnect the negative jump start cable from the negative terminal of the electrical source.
16. Disconnect the positive jump start cable from the positive battery terminal of the stalled machine.
17. Disconnect the positive jump start cable from the positive terminal of the electrical source.
18. Conclude the failure analysis on the starting system and/or the charging system. Check the machine while the engine is running and the charging system is in operation.
