5.4.1 Observe the followings when handling the battery
■
Charge the battery in the well-ventilated place.
If charge the battery in the badly ventilated place, there is ignition or fire risk due to inflammable
gas.
■
Prevent (+) pole from contacting (-) pole when connecting cable of battery.
Incorrect connection may produce spark and ignite inflammable gas in the battery thus leading to
explosion.
■
Disconnect the negative terminal cable when maintaining the generator.
■
Electrolyte contains thin sulfuric acid. Therefore incorrect operation may lead to serious injury
or damage.
If clothes or skin touches electrolyte of storage battery, immediately wash with plenty of water. If
eyes touch electrolyte of battery, immediately wash with plenty of water and consult physician.
■
If electrolyte of battery is below LOWER LEVEL, do not use the battery. Inside aging of battery
leads to shorter life even explosion.
■
Start or stop the starter continuously will consume much battery energy, even burn the starting
motor.
■
Never check the battery until the engine is stopped.
■
Don’t disconnect the battery when the generator is still running,
otherwise, the motor or control circuit may be damaged or burnt
out.
5.4.2 Check the battery
(1) Check electrolyte level
Check the battery indicator lamp for maintenance free battery.
Blue lamp indicates sufficient power while red lamp indicates insufficient power.
(2) Check specific gravity of electrolyte level
When the engine starts, the rotation speed is slow, so please charge the battery. If the machine
still can’t start after charging, you should change the battery.
Measure the specific gravity of electrolyte level if engine starts bad. The purpose is to check if
any shelf depreciation.
If rest volume is below 75%, charge the storage battery.
Check the battery voltage before using if the battery hasn’t been used for 3 months. Charge the
battery if the voltage is lower than 12V. Starting the generator in low voltage will burnt the starting
motor.
Calculate the charging ratio on the basis of measured specific gravity and according to the below
table
