z
There is an indicator on the cover of the battery. The green light means it can be used, the black
light means it should be charged, and the white light means it should be replaced. Replace with a
new battery after the white light indicator.
z
Routinely recharge the battery if the battery lacks electric power during use to prevent the
capability of battery sulfate going down.
z
If the battery is installed, disassemble it and put it in a dry and well ventilated place if it is not
used for long time (generally more than 15 days). Recharge the battery every 3~6 months (based
on whether the indicator is black or not).
8.17 Charging of Storage Battery
Explosion may occur if the storage batteries are charged in the wrong way. So follow the storage
battery instructions in this user manual. Do as follows:
z
Charge with constant voltage is recommended:
¾
Complementary charge: charge 16 hours at 16.0 Voltage (max current is less than 25A)
¾
Normal charge: charge 24 hours at 16.0 Voltage (max current is less than 25A).
z
Connect the positive pole of the charging machine with the negative pole of the storage battery,
and then connect the negative pole of the charging machine with the positive pole of the storage
battery. Never reverse.
z
Examine the vent of the battery to prevent blockage, otherwise it may explode.
z
Lower the charging voltage or current if the electrolytes are over 45
℃
to prevent spurt out of
electrolytes due to high temperatures.
z
Never
overcharge during use or charging to prevent early invalidation due to water loss, grid
increasing and diachylon dropping.
8.18 Starting to Use Voltage-Raising Method
The wrong connection of voltage-raising cable may lead to fire, so please do as follows:
z
Two operators are needed to start voltage-raising start (one sits on the operator seat).
z
Two machines are not allowed to touch when one is starting.
z
Turn off all the starting switches of the normal machine and the broken machine when connecting
z
Connect the positive (
+
) cable first when the voltage-raising cable is connected. Cut off the
