SOME NOTES ABOUT POWER CORDS 

 

Long or thin cords can require more wattage from a generator to power an electrical device. Figure 9 shows the recommended cords according to 
the power requirement of the electrical device. When using cords that exceed these specifications, allow for the electrical device to have a slightly 

higher rated wattage requirement.

DC Usage 

 

                                                                                

 

The DC outlet is only for recharging 12 Volt automotive-type batteries. Do not connect any other device to this outlet.

 

 

                                                                                

  

Use this generator only for recharging 12 Volt batteries. NEVER attempt to jumpstart a car with this generator.

 

 

                                                                                

 

Failing to use the correct procedure can cause a battery to explode, seriously injuring anyone nearby. Keep heat, sparks, flame and 

smoking materials away from the battery.

 

 

 

To connect 12 Volt batteries to the DC outlet: 
1. Connect one charging wire to the positive terminal of the battery and the other charging wire to the negative terminal of the battery. 

2. Connect the free end of the positive wire to the positive side of the outlet on this generator. 

3. Start this generator. 

4. Carefully connect the free end of the negative wire to the negative side of the outlet on this generator. 

5. When disconnecting, always disconnect the wires from this generator first to avoid a spark. 
 

                                                                                 

 

Storage 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 the skin, flush with water. 

 

• If battery acid gets in the eyes, flush with water and immediately call a physician. 

 

• If battery acid is swallowed, drink large quantities of milk and immediately call a physician.
