Step 1 - Fill Oil The generator is shipped without oil. User must add the proper amount of oil before operating the generator for the first time. The oil capacity of the engine crankcase is 20 fluid oz. Select good quality detergent oil bearing the American Petroleum Institute (API) service classifications SJ, SL, or SM. (Synthetic oils may be used.) Use the SAE viscosity grade of oil from the following chart that matches the starting temperature anticipated before the next oil changes.
Step 2- Add Gasoline WARNING: This generator may emit highly flammable and explosive gasoline vapors, which can cause severe burns or even death if ignited. A nearby open flame can lead to explosion even if not directly in contact with gasoline. x x x x x x x x Do not operate near open flame. Do not smoke near generator. Always operate on a firm, level surface. Always turn generator off before refueling. Allow generator to cool for at least 2 minutes before removing fuel cap.
Step 3- Ground the Generator WARNING: Failure to properly ground the generator can result in electrocution. Ground the generator by tightening the grounding nut against a grounding wire (see figure 5). A generally acceptable grounding wire is a No. 12 AWG (American Wire Gauge) stranded copper wire. This grounding wire should be connected at the other end to a copper or brass grounding rod that is driven into the earth. Wire and grounding rod are not included in generator contents.
STARTING THE GENERATOR Before starting the generator, make sure you have read and performed the steps in the “GENERATOR PREPARATION” section of this manual. If you are unsure about how to perform any of the steps in this manual please call (800) 232-1195 M-F 8-5 CST for customer service. DANGER: CARBON MONOXIDE. Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide (CO). This is a poison gas you cannot see or smell.
To start your generator, perform the following steps: 1. No electrical devices should be connected to the generator during starting. Devices can make it difficult for the engine to start. 2. Check that the generator is properly grounded (see “Ground the Generator”). 3. Check the oil and fuel levels. 4. Turn the fuel valve to the “ON” position (see figure 6). 5. Move the choke lever to the “CLOSED” position (see figure 7). 6. Set the engine switch to the “ON” position. 7.
Step 1- Check the Oil Oil consumption is normal during generator usage. The generator is equipped with a low-oil shutoff to protect it from damage. The oil level in the engine should be checked before each use to ensure that the engine crankcase contains sufficient lubricant. To check or add oil, follow these steps: 1. Make sure the generator is on a level surface. Clean around oil fill. 2. Remove the oil filler/dipstick cap and check oil level. 3.
Wire Gauge) stranded copper wire. This grounding wire should be connected at the other end to a copper, brass, or steel-grounding rod that is driven into the earth. Wire and grounding rod are not included in generator contents. Grounding codes can vary by location. Contact a local electrician for area codes.
If these specifications are not available, you may estimate the Watts required by your device using the chart in figure 10. When the running wattage requirement of each electrical device has been determined, add these numbers to find the total running wattage needed. If this number exceeds the running wattage of the generator, DO NOT connect all these devices. Select a combination of electrical devices, which has a total running wattage lower than or equal to the running wattage of the generator.
1. Plug in each electrical device with the device turned off. NOTE: Be sure to attach appliances to the correct receptacles (outlets). Connect standard 120 Volt, single phase, 60 Hz loads only to the 120 Volt receptacles. Connect 120 Volt, single phase, 60Hz loads with a NEMA L5-30 plug only to the 120 Volt receptacle See Figure 11 for a depiction of each of these receptacles. 2. Push in the circuit reset buttons to the “on” position (NOTE: They may be pushed in already).
STOPPING THE GENERATOR Procedure to Stop Generator NOTE: Stopping the motor or unplugging cords from the generator while it is supplying power to devices will possibly damage the voltage regulator and result in low or no power output until the voltage regulator is replaced. Following the stopping procedure will minimize the possibility of damaged voltage regulators. 1. Turn off all electrical devices being powered by generator prior to unplugging them from the generator. 2.
MAINTENANCE / CARE Proper routine maintenance of your generator will help prolong the life of your machine. Please perform maintenance checks and operations according the schedule in figure 13.

CAUTION: Never perform maintenance operations while the generator is running.
Figure 14- Checking the oil Changing/ Adding Oil Change the oil according to the maintenance schedule in figure 13. Change the oil when the engine is warm. This will allow for complete drainage. Change oil more often if operating under heavy load or high ambient temperatures. It is also necessary to drain the oil from the crankcase if it has become contaminated with water or dirt. The oil capacity of the engine in this generator is 20 fluid oz. Add oil when the oil level is low.
Air Cleaner Maintenance Routine maintenance of the air cleaner helps maintain proper air flow to the carburetor. Check that the air cleaner is free of excessive dirt. 1. 2. 3. 4. 5. Unhinge the clasps at the top and bottom of the air cleaner cover (see figure 17). Remove the sponge-like elements from the cover. Wipe the dirt from inside the empty air cleaner cover. Wash the sponge-like elements in household detergent and warm water. Allow to dry.
Spark Plug Maintenance The spark plug is important for proper engine operation. A good spark plug should be intact, free of deposits, and properly gapped. To inspect the spark plug: 1. Pull on the spark plug cap to remove it. 2. Unscrew the spark plug from the generator using the spark plug wrench included with this product (see figure 19). 3. Visually inspect the spark plug. If it is cracked or chipped, discard and replace with a new spark plug. 4. Measure the plug gap with a gauge (see figure 20).
STORAGE / TRANSPORT PROCEDURES CAUTION: Never place any type of storage cover on the generator while it is still hot. If the generator is being stored for short periods of time (30 – 60 days), add stabilized fuel to the fuel tank until full. NOTE: Filling the tank reduces the amount of air in the tank and helps reduce deterioration of fuel. Run the engine for 2 – 3 minutes allowing stabilized fuel mixture to circulate through the carburetor.
