- Keep the unit dry.
- DO NOT allow the unit to come into contact with rain or moisture.
- DO NOT operate the unit if you, the unit, the device being operated, or any other surfaces that may come in contact
with any power source are wet. Water and many other liquids can conduct electricity, which may lead to serious
injury or death. - Do not place the unit on or near heating vents, radiators, or other sources of heat.
- Do not place the unit in direct sunlight. The ideal air temperature for operation is between 50° and 80° F.
- Do not use the converter near an open engine compartment where fumes may accumulate.
- Do not modify the AC receptacles in any way.
- Keep the unit well ventilated to properly disperse heat generated while it is in use. Make sure there are several
- USING THE CONVERTER It is important to know the continuous wattage of the device you plan to use with the converter. The unit must be used with devices drawing 200 watts or less. If the wattage is not marked on the device, use only devices that draw less than 1.7 amps of AC. Devices like TVs, fans, or electric motors require additional power to start
(commonly known as the “starting” or “peak” power). The unit can supply a momentary surge in wattage; however, even devices rated less than the maximum 200 watts can exceed the
converter’s surge capability and cause an automatic overload shutdown. Do not use the converter with a product that draws a higher wattage than the converter can provide, as this may cause damage to the converter and the product. Make sure the device you are using is compatible with a modified sine wave
converter.
MAINTENANCE INSTRUCTIONS
- After use and before performing maintenance, unplug and disconnect the jump starter.
- Use a dry cloth to wipe all battery corrosion and other dirt or oil from the battery clips, cords, and the jump starter case.
- Ensure that all of the jump starter components are in place and good working condition.
- All servicing should be performed by qualified service personnel.
MOVING AND STORAGE INSTRUCTIONS
- Store inside, in a cool, dry place.
- Do not store the clips on the handle, clipped together, on or around metal, or clipped to cables. The clips on the jump
starter are live when the switch is in the ON position and will produce arcing or sparking if they come in contact with each
other. To prevent accidental arcing, always place the switch in the OFF position and keep the clips on the storage holders when not using them to jump-start a vehicle. - If the jump starter is moved around the shop or is transported to another location, take care to avoid/prevent damage to the
cords, clips, and jump starter. Failure to do so could result in personal injury or property damage. - KEEP FULLY CHARGED. Charge the jump starter’s internal battery immediately after purchase, after every use, and every 30 days. All batteries are affected by temperature. The ideal storage temperature is 70°F. The internal battery will gradually self-discharge (lose power) over time, especially in warm
environments. Leaving the battery in a discharged state may result in permanent battery damage. To ensure satisfactory
performance and avoid permanent damage, charge the internal battery every month.
