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.
Use only equal voltage for starting. Check the battery and
starter voltage rating of your machine. Use only the same
voltage for jump starting. Use of a welder or higher voltage
damages the electrical system. This machine has a 12 volt
starting system. Use only the same voltage for jump
starting.
Refer to Special Instruction, SEHS7633, "Battery Test
Procedure" available from your Caterpillar dealer, for
complete testing and charging information.
1. Engage the parking brake. Lower the work tools to the ground.
Reference: Refer to Operation and Maintenance Manual, "Equipment Lowering with Engine
Stopped".
2. Move all control levers to the HOLD or NEUTRAL position.
3. Turn the engine start switch key to the OFF position and turn all accessory switches to the OFF
position.
4. Move the machine that is being used as an electrical source near the stalled machine so that the jump
start cables reach the stalled machine. Do not allow the machines to contact each other.
5. Stop the engine of the machine that is being used as an electrical source. If you are using an auxiliary
power source, turn off the charging system.
6. Ensure that battery caps on both machines are tight and correctly placed. Ensure that batteries in the
stalled machine are not frozen.
7. Connect the positive jump start cable to the positive cable terminal of 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 cable terminal of the electrical
source.
9. Connect one negative end of the jump start cable to the negative cable 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 connect the jump start cable 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 on the auxiliary power source.
