1.1.3 CHARGING PROCEDURES
(1) Normal charge
① Turn off the key switch and apply the parking brake.
② Make sure that the power supply at the facility side is off and insert the plug into the
receptacle at the truck side.
The plug at the truck side is a locking type. Insert the plug securely until it reaches the locked
position. Then, insert the plug into the receptacle at the facility side when it is equipped with
the power service outlet.
③ When the power supply at the facility side is turned on and the START button at the charging
operation panel is pressed, the CHARGING lamp lights up and the charging is started. Then,
the humming is heard from the transformer, which shows that the charger is operating. The
charging state is also displayed on the LCD panel.
Note: If the battery is not connected or the power supply at the facility side is 0-volt, the
charging operation cannot be started.
④ The charging is automatically terminated after it continues for 8 to 10 hours (the charging
time varies with the amount of discharge). The battery is not so exhausted, the charging may
continue for a short time (a few minutes).
Note: If power failure occurs during charging and is remedied within 120 hours, battery
charging is automatically started again.
⑤ Make sure that the CHARGING lamp is turned off, turn off the power supply at the facility
side. Remove the plug at the truck side with its lock lever pressed.
⑥ After charging is nished, measure the specied gravity of the battery electrolyte to check if
the proper charging is carried out.
(2) Boosting charge
If the residual level gauge of the LCD panel is probable to indicate level 3 or less after
completing the day’s work, it is recommended that boosting charge is carried out by using a rest
period.
The starting procedure of the boosting charge is same as that of the normal charge, but be sure
to press the STOP button when terminating the boosting charge.
(3)Equalizingcharge
Normally the battery does not need equalizing charge because when the battery needs it, the
microcomputer detects it and automatically puts the charger in equalizing charge operation.
However, manual equalizing charge is needed if:
Puried water is added to the battery electrolyte
•
The difference of the specic gravity in each cell is 0.02 or more.
•
Overdischarge more than 100% occurs.
•
The procedure for carrying out the equalizing charge is as follows:
① Press the SUPER EQUALIZE button after taking the same steps as needed for normal charge,
so that the CHARGING lamp and SUPER EQUALIZE lamp light up.
