DISCHARGED BATTERY 3
q It is dangerous to charge a battery when installed on a
machine. Make sure that it is removed before charging.
q When checking or handling the battery, stop the
engine and turn the starting switch key to the OFF
position.
q The battery generates hydrogen gas, so there is a haz-
ard of explosion. Do not bring lighted cigarettes near
the battery, or do anything that will cause sparks.
q Battery electrolyte is dilute sulfuric acid, and it will
attack your clothes and skin. If it gets on your clothes
or on your skin, immediately wash it off with a large
amount of water. If it gets in your eyes, wash it out with
fresh water and consult a doctor.
q When handling batteries, always wear safety glasses
and rubber gloves.
q When removing the battery, first disconnect the cable
from the ground (normally the negative (-) terminal).
When installing, install the positive (+) terminal first.
If a tool touches the positive terminal and the chassis,
there is danger that it will cause a spark, so be
extremely careful.
q If the terminals are loose, there is danger that the
defective contact may generate sparks that will cause
an explosion.
q When removing or installing the terminals, check
which is the positive (+) terminal and which is the neg-
ative (-) terminal.
Battery Removal and Installation 3
q Before removing the battery, remove the ground cable (normally connected to the negative (-) terminal).
If any tool touches between the positive terminal and the chassis, there is a hazard of sparks being generated.
q When installing the battery, connect the ground cable last.
q When replacing the battery, fix the battery securely in position with the battery mounting clamp.
Tightening torque of mounting bolt: 9.8 to 19.6 Nm (1.0 to 2.0 kgm)
q For machines equipped with the optional battery isolator switch, turn the starting switch OFF before removing
or replacing the battery, then wait for at least 3 minutes before turning the battery isolator switch OFF.
