Starting Engine with Booster Cable
Start the engine with booster cable as described
below.
Cautions on Connecting/Disconnecting
Booster Cable
WARNING!
• Never let the (+) terminal and (-) terminal
come into contact with the other when
connecting the cable.
• Wear goggles and rubber gloves when
starting the engine with the booster cable.
• Do not let the normal machine and machine
in failure come into contact with the other.
Because the battery produces hydrogen
gas, sparks around the battery can cause
explosion.
• Do not make mistakes in connecting the
booster cable. Note that there will be some
sparks when making the last connection.
Make this connection at the location as far
as possible from the battery.
• Do not let the booster cable clips contact
the other or machine when disconnecting
the booster cable.

normal machine and the broken machine in
OFF position when the booster cable is
connected.
• Do not connect to wrong side [connecting
(+) to (-), (-) to (+)] when connecting the
booster cable.

battery of the broken machine when
connecting the ground as the last
procedure.
