negative pole of storage battery with positive pole of machine.
z
Put the battery on the shaft using upside fixing method or downside fixing method to prevent
lose.
z
There is indicator on the cover of battery. Green light means it can be used, black light means it is
charging, white light means charging is finished. Please replace with another one after white
light.
z
Please recharge the battery in time if the battery lacks electric power during using to prevent the
capability of battery sulfate going down.
z
If the battery is assembled, disassemble it and put it at dry and ventilative 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
It may explode if the storage battery charges in the wrong way. So deal with the battery as the dealing
program and the program in user manual. Do as follows:
z
Constant voltage charge:
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 charging machine with negative pole of storage battery, and then
connect negative pole of charging machine with positive pole of storage battery. Do not reverse.
z
Examine the vent of battery to prevent block, otherwise it may explode.
z
Low the charging voltage or current if the electrolyte overpass 45
℃
to prevent spurt out of
electrolyte due to high temperature.
z
Never
overcharge during using or charging to prevent early invalidation due to water lost, grid
increasing, diachylon dropping.
8.18 Starting Using Voltage-Raising Method
The wrong connection of voltage-raising cable may lead to fire, so please do as follows:
z
Two operators are needed for voltage-raising starting (one sits on the operator seat).
z
The two machines are not allowed to touch when one is starting.
z
Turn off all the starting switches of normal machine and iffy machine when connect the
