5.The charging was done when the ammeter decreased close to
“0” .
6. After the charging is finished, the power should be turned off first, and then the
battery clamp should be removed from the battery.
Note :
● In the course of charging, the temperature of electrolytic solution in the battery
should not be more than 45
℃. If the charging is not finished and the temperature
reaches 45
℃, the charging current should be lowered down so as to prolong the charging
time and make the temperature of electrolytic solution not increase continuously
until the charging is completed.
● The following phenomena may occur after charging is finished: Specific gravity
of battery solution is close to 1.28KG/L; Terminal voltage of battery is increased
to more than 14V (or 28V); Electrolytic solution is heavily bubbled up.
Ⅵ MAINTENANCE
● Regular maintenance and repair work can ensure the machine is properly used and its
condition complies with the safety requirements.
● Any improper or incorrect operation may cause the failure and damage for the machine.
