USING JUMPER CABLES
STARTING ENGINE BY JUMPER CABLES
• Combustible gas (hydrogen gas) is generated in the battery. Do not allow sparks or flames to come in contact
with the battery to avoid catching a fire and triggering an explosion.
• Do not allow the normal machine to come in contact with the disabled one.
• Wear protective glasses and rubber gloves when using jumper cables to start the engine.
• Never allow the positive and negative side clips of the jumper cables to come in contact with each other when
connecting the jumper cables.
• Do not mistake positive (+) for negative (-) or vice versa in the jumper cable connection. When the negative
jumper cable is finally connected to the upper structure of the disabled machine, it may generate sparks.
Connect the jumper cable to a ground surface as far as possible from the battery.
• If the battery electrolyte is frozen, do not attempt to start the engine with another power supply.
• Wrong connection of the jumper cables may cause explosion of the battery.
• The starting system of this machine is 24 volts. Therefore the boost battery voltage in use should be 24 volts.
The application of high voltage employed for a welding machine, etc. in engine start may cause damage to the
electrical system.
• Use the battery of which the capacity is equivalent to that of the disabled machine for the normal machine.
• Select the jumper cables and clips with a proper size for the battery.
• Check the jumper cables and clips for damage and corrosion.
• Connect the clip securely.
• Check that the control lock lever is in the "LOCKED" position.
• Check that each control lever is returned to the neutral position.
• The starter switches on both the normal and disabled machines must be held in the "OFF" position. Because
when the power is connected, it may cause unexpected move of the machines and it is dangerous.

1.
For the normal machine, put the attachment on the
ground, return all control levers to the neutral
position and then set the control lock lever to the
"LOCKED" position.
2.
Set the starter switch to the "OFF" position for both
the normal machine and the disabled machine.
3.
Remove the terminal cover of the battery, and
connect the jumper cable (red) clip to the positive
(+) terminal on the battery of the disabled machine.
4.
Connect the jumper cable (red) clip to the positive
(+) terminal on the battery of the normal machine.
5.
Connect the jumper cable (black) clip to the
negative (-) terminal on the battery of the normal
machine.
6.
Finally, connect the clip of the other end of the negative (-) jumper cable (black) to the upper structure frame of
the disabled machine.
7.
Start the engine of the normal machine, and run it for about 10 minutes at high idle.
The battery of the disabled machine is partially charged.
