Service battery
Handle the battery correctly
• Never use flames or allow sparks
to generate near the battery. The
battery releases
hydrogen gas and oxygen gas.
Any flames or sparks in the vicin-
ity could cause an explosion.
• Do not use the battery the fluid level of which is low-
ered below the lower limit line. Sustained use of the
battery could result in an explosion.
• Do not short the battery terminals with a tool or other
metal object.
• When disconnecting battery cables, always remove
the cable from the negative (-) terminal first. When
reconnecting the cables, attach the cable to the posi-
tive (+) terminal first.
• Charge the battery in a well-ventilated area, with all
filling hole plugs removed.
• Make sure the cable clamps are securely installed on
the battery terminals. A loose cable clamp can cause
sparks that may result in an explosion.
• Before servicing electrical components or conducting
electric welding, set the battery switch to the [Open/
OFF] position or disconnect the cable from the nega-
tive (-) battery terminal to cut off the electrical cur-
rent.
• Electrolyte (battery fluid) contains dilute sulfuric acid.
Careless handling of the battery can lead to the loss
of sight and/or skin burns. Also, keep the battery fluid
off the mouth.
• Wear protective goggles and rubber gloves when
working with the battery (when adding water, charg-
ing, etc.).
• If electrolyte is spilled onto the skin or clothing,
immediately wash it away with lots of water. Use
soap to thoroughly clean.
• The battery fluid can cause blindness if splashing
into eyes. If it gets into eyes, immediately flush it
away with plenty of clean fresh water, and seek
immediate medical attention.
• If the battery fluid is accidentally swallowed, gargle
with plenty of water, then drink lots of water, and
seek immediate medical attention.
CAUTION
flammable
When abnormality occurs
Stop overheated engine after cooling run
Even if the engine comes to overheat, do not stop the
engine immediately. Abrupt stopping of an overheated
engine can cause the coolant temperature to rise, re-
sulting in seized engine parts. If the engine comes to
overheat, run the engine at low idling speed (cooling
operation), and stop the engine after the coolant tem-
perature lowers sufficiently.
Do not add coolant immediately after stopping the en-
gine. Adding coolant to a hot engine can cause the cyl-
inder heads to crack due to sudden change in
temperature. Add coolant little by little after the engine
cools down to room temperature.
Avoid immediate restart after abnormal stop
If the engine stops abnormally, do not restart the en-
gine immediately. If the engine stops with an alarm,
check and remedy the cause of the problem before re-
starting. Sustained use of the engine without any rem-
edy could result in serious engine problems.
Avoid continuous engine operation with too
low oil pressure
If an abnormal engine oil pressure drop is indicated,
stop the engine immediately, and inspect the lubrica-
tion system to locate the cause. Continuous engine op-
eration with low oil pressure may cause bearings and
other parts to seize.
Stop the engine immediately if the fan belt
breaks
If the fan belt breaks, stop the engine immediately.
Continuous engine operation with the broken fan belt
could cause the engine to overheat and thereby the
coolant to boil into steam, which may gush out from the
reserve tank or radiator, and cause personal injuries.
