Don’t Overload the Generator
Make sure you can supply enough rated watts and surge watts for all electrical devices connected to the generator. Rated watts refer to the power a generator must supply to keep a device running. Surge watts refer to the power a generator must supply to start an electrical device. This power surge for starting a device usually lasts between 2-3 seconds but this additional output must be taken into account when selecting the electrical devices you plan to attach to the generator. To prevent overloading the generator take the following steps:

1. Add up the total rated wattage of all electronic devices that will be connected to the generator simultaneously.
2. Estimate surge watts by adding the item(s) with the highest output (it is unnecessary to calculate the surge output for all devices as they should be connected one at a time).
3. Add the Surge Watts to the total Rated Watts in step 1. Keep total load within generator’s power capacity.

Operating Voltage and Frequency
Operating voltage and frequency requirement of all electronic equipment should be checked prior to plugging them into this generator. Damage may result if the equipment is not designed to operate within a +/- 10% voltage variation, and +/- 3 Hz frequency variation from the generator name plate ratings. To reduce the risk of damage, always have an additional load plugged into the generator if solid state equipment (such as television set) is used. A power line conditioner is recommended for some solid state applications.

Wattage Reference Guide
(Wattages listed are approximate. Check electrical devices for actual wattage.)

WARNING

Never exceed the generator’s wattage/amperage capacity. This could damage the generator and / or connected devices.

3-in-1 Meter
The multifunction meter operates whenever the engine is running and keeps track of how many hours, frequency, and voltage is being used on the generator.

Power Management

• Start the engine without anything connected to the generator.
• When the engine has stabilized, plug in and turn on first load. It is strongly recommended to plug in devices with the largest power requirement first and the smallest power requirement last to help prevent overloading the generator.
• Allow generator output to stabilize (engine and attached devices run evenly) before plugging in the next load.

Cold Weather Operation
Under humid conditions where temperatures drop to 40ºF (4ºC) the carburetor and/or crankcase breather system may begin to freeze. To prevent icing take the following steps:

• Replace any old fuel with clean, fresh fuel.
• Use synthetic 5W-30 or SAE 5W-30 engine oil. Check oil daily or after every 8 hours of use.
• Ensure generator is serviced according to the maintenance schedule under “Maintenance” section of manual.
• Shelter unit from elements.
