English Troubleshooting Guide BE SURE TO FOLLOW SAFETY RULES AND INSTRUCTIONS Problem Portable power station/charger does not operate or turn ON when ON/OFF button is pressed. Portable power station/charger indicates low battery even though the battery's fuel gauge still shows 1 green LED light. Portable power station/charger doesn't operate when near or below freezing. Possible Solution Check that all four batteries have sufficient charge (at least 1 green LED light, ideally 2 or 3 green LED lights on battery fuel gauge, if equipped). Remove batteries and reinsert fully into the tool. Check that batteries are within operating temperature (solid yellow light will illuminate if battery overtemp condition). Be sure nothing is plugged into "Charger-In" plug. Be sure load has not exceeded capacity of portable power station/charger. Depending on the age and condition of battery, the battery may be exhausted even with 1 bar still showing on the fuel gauge. Replace battery with new battery. Store battery packs in warm environment. Start using item; once portable power station/charger starts working, the batteries will heat up. Portable power station/charger has overheated. Use portable power station/charger in cooler location; keep out of direct sun and heat. Use in horizontal orientation. (Do not block air inlet or outlet.) Cooling fan may need cleaning. Refer to the Maintenance section. If battery pack is overheated, use larger capacity battery. Refer to next Problem. Portable power station/charger turns off during high power operation. Device does not operate with portable power station/charger. Front panel lights blinking and portable power station/charger not working. Portable power station/charger does not charge. Check to make sure load does not exceed capacity of portable power station/charger (15 amps). If it trips a 15 amp circuit breaker, it will likely trip the portable power station/charger. Try using four of the same, premium (3.0Ah or greater) batteries fully charged. Compact (2.0Ah or less) batteries may not provide the output needed for high power operation. Consult manufacturer of device for use with modified sine wave. Portable power station/charger is in system fault. For example, if overloaded, reduce load and press power button to reset. Check the connection of the extension cord on both ends; be sure female end is securely plugged into Charger-In plug of the portable power station/charger. Check that electricity is flowing to extension cord using another device (light, tool, etc.). Remove batteries and reinsert fully into the tool. Check that the portable power station/charger and all batteries are within operating temperature (red flashing and yellow solid lights will illuminate if battery charging overtemp condition). 10
