CAUTION: Always run a test to establish whether the converter will operate a particular piece of
equipment or device.
In the event of a power overload, the converter is designed to automatically shut down. This safety
feature prevents damaging the converter while testing devices and equipment with the 400-watt range.
If powering more than one device, start one device at a time to avoid a power surge and/or converter overload.
The surge load of each device should not exceed the converter's continuous operation wattage rate.
IMPORTANT: If you are using the power converter to operate a battery charger, monitor the temperature
of the battery charger for about 10 minutes. If the battery charger becomes abnormally warm, disconnect
it from the converter immediately.
NOTE: You can use an extension cord from the converter to the device without significantly decreasing the
power being generated by the converter. For best operating results, the extension cord should be no longer
than 50 feet (15.24 meters).
IMPORTANT: This converter uses a modified sine waveform (diagram A) which is not quite the same as
power company electricity (diagram B). For the following devices, we strongly recommend that you use
caution and check the device's manual to make sure it is compatible with modified sine waveform.
1. Switch mode power supplies
2. Linear power supplies
3. Class 2 transformers
4. Line filter capacitors
5. Shaded pole motors
6. Fan motors
7. Microwave ovens
8. Fluorescent and high intensity lamps (with a ballast)
9. Transformerless battery chargers
Using the converter with any of these devices may cause the device to run warmer or overheat.

Powering a 110V AC Device
6.6
1. Ensure the battery clips are securely on the storage holders.
2. Make sure the 110V AC device to be operated is turned OFF.
3. Plug the 110V AC device into the AC power outlet on the back of the jump starter and place the
converter switch in the "120V" position. The GREEN LED will light, indicating the converter is on.
4. Turn the device on.
5. If the device does not operate properly when first connected to the converter, push the converter rocker
switch ON, OFF, and ON again in quick succession. If this procedure is not successful, it is likely that the
converter does not have the required capacity to operate the device intended.
6. To disconnect: Turn off the device, place the converter switch in the "O" (OFF) position, then unplug the
device from the 110V AC power outlet.
7. Charge the jump starter as soon as possible after each use.
