PRECAUTIONS FOR CHARGING BATTERY
k k
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 (3-287)" 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.
START ENGINE WITH JUMPER CABLES
• When connecting the cables, never contact the positive (+) and negative (-) terminals.
• Always wear protective eyeglasses and rubber gloves when starting the engine by using the jumper
cable.
• Do not bring the normal machine into contact with the failed machine.
The sparks caused near the battery could ignite the hydrogen gas generated from the battery, so be
careful not to let it happen.
• Make sure that there is no mistake in the jumper cable connections.
Connect the final cable to the engine block of the failed machine.
At this time, sparks are generated. Accordingly, connect it to a point as far from the battery as pos-
sible.
• Do not bring the clips in contact with other clips or with the machine when disconnecting the jump-
er cable.
• Never start the engine by short-circuiting the starting motor (jump start).
