ⅥOPERATION INSTRUCTIONS FOR
CHARGER AND BATTERY
To ensure that the charger and battery are used correctly and the machine
is kept from damage, the following rules must be followed:
1、Operation instructions for the battery
●When battery does not have sufficient electricity. the terminal voltage of it can be
normal, which means the 12V battery has the terminal voltage of 12V and the 24V
battery has the terminal voltage of 24V. The main physical phenomenon. which
indicates the insufficient electricity in the battery. is the changeof the specific
gravity of the battery solution. Normally, when the specific gravity of the battery
solution is 1.28KG/L, the electricity volume of battery is sufficient. If it is lower than
1.16KG/L, the battery is empty and won’t have any electricity.
●The voltage of battery can be deviated from the normal value only when the
battery is loaded or charged. When loaded, the voltage is lower than normal value
of terminal voltage, whereas it is higher than normal value when the battery is being
charged. If the battery is topped for some time (about 10-30 minutes) after it is loaded,
and the terminal voltage is still lower than normal value, the battery
may have quality defects.
●Remove the cover of the battery to see if the electrolytic solution in it is sufficient.
If not, add more distilled water into it till it is sufficient so as to make it prepared
for charging.
●As the electrolytic solution in the battery is dilute sulfuric acid and strongly
erosive, it can’t contact the skin or clothes. In case the electrolytic solution has
contacted the skin, the contacted area should be washed with water immediately
and the contacted person should be sent to the hospital for medical treatment timely.
2、Correct charging method
●It is permitted to charge the batteries with the same capacities in parallel
connection or when connected in series. The terminal voltage of battery in parallel

10
connection or connected in series must match the output voltage of the charger.
Normally, it is recommended to charge the batteries when they are connected in
series so as to ensure the current passing each battery has the same value.
●Connecting the batteries: Connect the (red) anode of battery clamp to the anode
of the battery and the corresponding terminal (12V or 24V) of the charger. Connect
the (black) cathode of battery clamp to the cathode of the battery. If the battery of the
car needs to be charged, first you should connect the charger to the terminal which is
not connected with the chassis, then connect the other terminal of charger to the chassis.
The connecting points must be far away from the battery and fuel tubes.
●Insert the power plug. First turn the power switch to “I”position, then turn the
function switch “charge/start” to “charge” position. The ammeter will indicate the
reading for the current (fit for CD-220,CD-320,CD-420). CD-520 and CD-620 has the
options for charging time. For details, please refer to Section Ⅻ --Diagram for Current
Regulating.
●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.
●After the charging is finished, the power should be turned off first, and then the
battery clamp should be removed from the battery.
3、Auxiliary start
Note: Auxiliary start must be carried out by strictly following the
operation procedures specified for the product.
●First use the charger to fast charge the battery for 10-15 minutes.

11
●Connect any pole of the charger to the engine’s terminal not linked to the
chassis (with same poles, meaning the anode should be connected with
anode), connect the other pole to the engine’s terminal which is linked to the chassis.
●Read the related instructions for the engine as provided by the
manufacturer carefully.
●Insert the power plug, turn the power switch to “ON” position, then
turn the function switch “charge/start” to “start” position. And the engine
can be started.
Attention: The start time for each time is 3 seconds; the start for the second time should be
120 seconds later. Five times of cycled start are available. If the engine is continuously
started, 10 minutes of interval must be ensured between two start cycles so that the
transformer inside the device can be cooled for restarting the engine.

12
ⅫMAINTENANCE
●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.
●The warranty period for the machine is one year commencing from the date of
purchasing. Within this time, users can take the machine with the invoice to the
distributor or the designated department for repair.
●Before the maintenance work for machine is started, the operator must turn off the
main power at power distribution cabinet and the power switch of the machine.
●If the transformer is heating and no current is available from the transformer due to
the over current in the course of charging, it is because the over-heat protection device
inside the charger is started to protect the transformer. In this case, the user should wait
till the transformer is cooled to resume the charging process.
