Choosing the Right Power Cord
Long or thin cords can drain the power provided to an electrical device by the generator.
When using such cords, allow for a slightly higher rated wattage requirement for the
electrical device. See Figure 12 for recommended cords based on the power requirement of
the electrical device.

DC Usage
CAUTION: The DC receptacle is for recharging 12 Volt automotive-type batteries only.
Do not connect any other device to this receptacle.
CAUTION: Never try to jump start a car with your generator.
To connect a 12V battery to the DC battery charger on the front panel:
1. Connect one charging wire to the positive terminal on the battery and the other
charging wire to the negative terminal on the battery.
2. Connect the free end of the positive wire to the positive receptacle (outlet) on the
generator.
3. Start the generator.
4. Carefully connect the free end of the negative wire to the negative receptacle on the
generator.
5. When disconnecting, always disconnect the wires from the generator first to avoid a
spark.
DANGER: Stored batteries emit highly explosive hydrogen gas when charged. Batteries
also contain acid, which can cause severe chemical burns.
Do not allow open flames or cigarettes nearby for several minutes after charging a battery.
Always wear protective goggles and rubber gloves when charging a battery.
If battery acid gets on your skin, flush with water.
If battery acid gets in your eyes, flush with water and call a physician immediately.
If battery acid is swallowed, drink large quantities of milk and call a Physician immediately.
If your generator is the electric start model, once running, it will charge the battery on the
generator automatically. While charging, you can see the recharge indicator light lit, after
the battery is full, the light will turn off.
