Battery structure
(1) Electrolyte level
Check the level of fluid in the battery.
When the amount of fluid nears the lower limit, fill
with battery fluid (available in the market) to the
upper limit. If operation continues with insufficient
battery fluid, the battery life is shortened, and the
battery may overheat and explode.
Battery fluid tends to evaporate more quickly in
the summer, and the fluid level should be checked
earlier than the specified times.
If the engine cranking speed is so slow that the
engine does not start up, recharge the battery.
If the engine still will not start after charging,
replace the battery.
Remove the battery from the battery mounting
of the machine unit after daily use if letting the
machine unit leave in the place that the ambient
temperature could drop at -15°C or less. And store
the battery in a warm place until the next use the unit
to start the engine easily at low ambient temperature.
(2) Battery charge
Use a battery tester or hydrometer and check the
battery condition. If the battery is discharged,
recharge it.
(a) Measurement with a battery tester
When checking the battery with the batter tester,
connect the red clip of the tester to the battery
positive (+) terminal and black clip to the battery
negative (-) terminal by pinching them securely, and
judge the battery charge level from the indicator
position.
Green zone: Normal
Yellow zone: Slightly discharged
Red zone: Defective or much discharged
