17-3-1. Starting the engine using booster cables
To start the engine using booster battery cables, do the fol-
lowing.
Precautions for connecting and disconnecting the
booster cables
IMPORTANT
• The booster battery cables capacity and the clip size
should be suitable for the battery size.
• The battery of the normal machine should be the
same capacity as that of the machine in trouble.
• Check the booster battery cables and clips for an ab-
sence of damage, cracks, and corrosion.
• Securely connect the clips.
• When you start the engine using booster cables,
wear safety goggles.
• If you start the engine by taking electric power
from another machine, do not allow contact be-
tween your machine and the other machine.
• To connect the booster cables, begin with the
positive terminal, and to disconnect them, begin
with the negative terminal (ground side).
• If a tool touches the positive terminal and the ma-
chine at the same time, hazardous sparks may be
generated.
• Do not connect the booster cables to terminals
of reverse polarity. That is, never connect a neg-
ative terminal on one machine to the positive ter-
minal on the other machine.
• As the last step, connect the negative booster
cable to the upperstructure. At this time, sparks
will be generated. Connect the terminal to a point
as far away from the battery as possible.
