DC Applications
The DC output should only be used for recharging 12-volt
automotive lead acid type batteries, and do not charge
batteries while they are connected to a vehicle. Make sure
they have been totally disconnected prior to connecting to
the generator for recharging.
Note. Only use the DC leads provided with this
generator, when using the DC output.
When charging a battery the following instructions need to
be followed:
1. Disconnect the original leads from the battery.
2. Fully loosen the battery fluid filler caps.
3. Fill the battery cells with distilled water to the upper limit
if the battery is empty.
4. Measure the specific gravity fluid by using a hydrometer
and calculate the charging time in accordance with the
table shown (Fig. P).
5. For a fully charged battery, the specific gravity range shall
be within 1.26 to 1.28. It is recommended to be checked
and confirmed every hour.
6. Start the generator. Make sure the green output indicator
light (14) comes on. Allow the motor to run for a couple of
minutes to warm up prior to connecting any apparatus to
the generator.
7. Review the status of the Smart Throttle System selector
button (15), make sure it is set accordingly to your needs.
The Smart throttle system can be either set to “On” or
“Off”. In the “On” position, the charging current will be low
compared to if the switch was set to the “Off” position.
Note: Do not let the two clips of the DC cable ever short
together. Take extra care to connect the Red to the positive
of the battery and the black to the negative of the battery.
NEVER use any cable other than the one supplied with
this generator. When removing the plug from the generator
DO NOT place the plug on the ground, or on any other
surface until the clips are removed from the battery.
8. Connect the supplied DC plug lead into the DC socket
(16) and connect the alligator clips to the correct polarity.
Only use the DC cable provided with this generator.
9. Press the DC Circuit protector/reset button (17) to reset in
case the DC supply had previously been overloaded.
The generator will charge a wide variety of automotive lead
acid batteries, providing the battery is in reasonable condition.
Note. This usage is applicable for charging only 12V lead
acid automotive batteries. Only use the DC socket to charge
lead acid type batteries. DO NOT charge Nicad or any other
type of batteries.
WARNING.
• The battery gives off explosive gases; keep sparks,
flames and cigarettes away.
• Provide adequate ventilation when charging or using
batteries in an enclosed space.
• The battery contains sulfuric acid (electrolyte).
Contact with skin or eyes may cause severe burns.
Wear protective clothing and a face shield.
