PRECAUTIONS FOR REMOVING AND INSTALLING BATTERY
1.
Before removing battery, remove the ground cable (nor-
mally connected to the negative (-) terminal).
If
any
tool
touches the positive terminal of the battery and
the chassis, there is a danger that it will cause a spark.
Loosen the nuts of the terminal and remove the wires from
the battery.
2.
When replacing the battery, fix the battery body with the
battery mounting fixtures.
Tightening torque
Nut (A): 5.9 to 9.8 Nm {0.6 to 1.0 kgm}
Nut (B): 5.9 to 9.8 Nm {0.6 to 1.0 kgm}
3.
When installing the battery, connect the ground cable last.
Insert the hole of the terminal on the battery and tighten the nut.
Tightening torque: 5.9 to 9.8 Nm {0.6 to 1.0 kgm}
REMARK
The batteries are
on both sides at the rear of the machine. The ground wire side battery is on the right side of
the machine.
PRECAUTIONS FOR CHARGING BATTERY
WARNING
When charging the battery, if the battery is not handled
correctly, it
is dangerous that the battery may explode. Al-
ways follow the instructions in “PRECAUTIONS FOR DIS-
CHARGED BATTERY (3-248)” and the instruction manual
accompanying the charger, and observe the following.
• Set the voltage of the charger to match the voltage of
the battery to be charged. If the correct voltage is not
selected, the charger may overheat and cause an ex-
plosion.
• Connect the positive (+) charger clip of the charger to
the positive (+) terminal of the battery, then connect
the negative (-) charger clip of the charger to the nega-
tive (-) terminal of the battery. Be sure to attach the
clips securely.
• Set the charging current to 1/10 of the value of the rat-
ed battery capacity; when performing rapid charging,
set it to less than the rated battery capacity.
If the charger current is too high, the electrolyte will
leak or the battery cells will dry up, and this may cause
the battery to catch fire and explode.
• If the battery electrolyte is frozen, do not charge the
battery or start the engine with a different power
source. It is dangerous that this may ignite the battery
electrolyte and cause the battery to explode.
• Do not use or charge the battery if the battery electro-
lyte level is below LOWER LEVEL line. This may cause
an explosion. Check the battery electrolyte level peri-
odically and add distilled water to bring the electrolyte
level to UPPER LEVEL line.
