Jump-Starting With Booster Cables; Jump Starting With Receptacles - Komatsu 730E Shop Manual

Jump-Starting With Booster Cables

• Always wear safety glasses or goggles when
starting the machine with booster cables.
• While jump starting with another machine, DO
NOT allow the two machines to touch.
• Ensure the parking brake is applied on both
machines.
• Ensure the size of the booster cables and clips
are suitable for the battery size. Inspect the
cables and clips for any damage or corrosion.
• Ensure the key switch and both battery
disconnect switches on the disabled machine are
in the OFF position.
• Connect the batteries in parallel: positive to
positive and negative to negative.
• Connect the positive (24VDC +) cable from the
good machine to the (24VDC +) on the disabled
machine first.
• Then connect the ground cable on the good
machine to the frame of the disabled machine,
as far away as possible from the batteries. This
will prevent a spark from possibly starting a
battery fire.
• Allow time for the batteries to charge.
NOTE: The batteries will charge even with the
battery disconnect switches are in the OFF position.
• If starting with a booster cable, perform the
operation with two people. One person in the cab
of the disabled machine, the other person
working with the jumper cables.
• If the batteries are low, DO NOT attempt starting
the machine with only one set of jumper cables
installed. Install the second set of jumper cables
in the same way as already described.
• Turn the battery disconnect switches to the ON
position and attempt starting.
• For booster cable removal,
disconnect the ground or
negative (-) cable first,
then the (24VDC +) cable
last.
• If any tool touches between the positive (+)
terminal and the chassis, it will cause sparks.
Always use caution when using tools near the
battery.
