Engine Key To start and stop the engine. Key position: OFF: To stop the engine. Key can be removed / inserted. ON: To run the engine after starting, or to pull start the unit. START: To start the engine by operating the starter motor. Do not turn the key switch to START position when the engine is running to prevent damage to the starting motor. Recoil Starter To start the engine, turn the key to on, pull the starter grip lightly until resistance is felt, then pull briskly.
Change the Voltage Selector Switch after turning the AC circuit breaker to OFF. The generator may be damaged if the Voltage Selector Switch is changed with the breaker in the ON position. Ground Terminal The generator ground terminal is connected to the frame of the generator, the metal non-current-carrying parts of the generator, and the ground terminals of each receptacle. DC Receptacle The DC receptacle may ONLY be used for charging 12 volt automotive type batteries.
WATTAGE REFERENCE CHART Electric equipment, especially engines produce strong current when being started. The table below offers references when you connect those installations to generator.

ASSEMBLY Wheel Kit Installation 1 Install the axle assembly on the generator. 2 Install the two wheels on the axle shaft using the flange nuts. 3 Install the two stands on the under frame using the flange nuts. Starter Cables Connection 1 Route the starter cable under the tank. 2 Connect the starter cable to the battery positive (+) terminal first, then to the negative (-) terminal. When disconnecting, disconnect at the battery negative (-) terminal first.
SAE 10W-30 is recommended for general, all-temperature use. Other viscosities shown in the chart may be used when the average temperature in your area is within the indicated range. 1 Remove the oil filler cap and wipe the dipstick clean. 2 Check the oil level by inserting the dipstick into the filler neck without screwing it in. 3 If the level is low, fill to the top of the oil filler neck with the recommended oil. Fuel Check the fuel gauge, and refill the tank if the fuel level is low.
Starting the Generator: CAUTION: Disconnect all electrical loads from the generator before attempting to start! 1. Make sure that the AC circuit breaker is in the OFF position. The generator may be hard to start if a load is connected. 2. Turn the fuel valve lever to the ON position. 3. The choke will need to be closed, slide the choke lever out to the CLOSED position. Turn the engine switch to the START position and hold it there for 5 seconds or until the engine starts. WARNING: 4.
OPERATING INSTRUCTIONS Connections to a Building Electrical System Connections for standby power to a building electrical system must be made by a qualified electrician. The connection must isolate the generator power from utility power, and must comply with all applicable laws and electrical codes. A transfer switch, which isolates generator power from utility power, is prerequisite.
AC Operation 1 Start the engine . 2 Turn the voltage selector switch to either position. With the voltage selector switch in the ‘‘120/240V’’ position, you can use the 120V and 120/240V receptacles simultaneously. If you require more 120V only power, then select the "120V only" position, this will disable the 120/240V twist lock plug. 3 Switch the AC circuit breaker ON. 4 Plug in the appliance. Most motorized appliances require more than their rated power for startup.
DC Operation The DC terminals may ONLY be used for charging 12 volt automotive type batteries. Connecting the battery cables: 1 Before connecting the battery charging cables to a battery that is installed in a vehicle, disconnect the vehicle ground battery cable from the battery negative (-) terminal. Batteries give off explosive gases; keep sparks, flames and cigarettes away. Provide adequate ventilation when charging or using batteries.
5 Reconnect the vehicle ground battery cable to the battery negative (-) terminal. High Altitude Operation At high altitude, the standard carburetor air/fuel mixture will be too rich. Performance will decrease, and fuel consumption will increase. A very rich mixture will also foul the spark plug and cause hard starting. Operation at an altitude that differs from that at which this engine was certified, for extended periods of time, may increase emissions.
REGULAR SERVICE PERIOD(2) Before each ITEM Performed at every indicated month or use operating hour interval, whichever comes first. Check ○ ● Engine oil Change Check ○ ● Air cleaner Clean Clean ● Sediment cup Clean-Adjust ● Spark plug Replace Clean ● Spark arrester Check-Adjust ● Idle speed Check-Adjust ● Valve clearance ● Combustion Clean chamber Clean ● Fuel tank and filter Check ● Fuel tube First month or 20 Hrs. Every3 months or 50 Hrs. ○ Every6 months or 100 Hrs. Every year or 300 Hrs.
Never run the generator without the air filter. Rapid engine wear will result. 1 Unsnap the air cleaner cover clips, remove the air cleaner cover, and remove the element. 2 Wash the air cleaner element in a solution of household detergent and warm water, then rinse thoroughly, or wash in nonflammable or high flashpoint solvent. Allow the air cleaner element to dry thoroughly. 3 Soak the air cleaner element in clean engine oil and squeeze out the excess oil.
The gap should be: 0.028 0.031 in (0.70 0.80 mm) 6 Check that the spark plug washer is in good condition, and thread the spark plug in by hand to prevent cross-threading. 7 After the spark plug is seated, tighten with a spark plug wrench to compress the washer. -If installing a new spark plug, tighten 1/2 turn after the spark plug seats to compress the washer. If reinstalling a used spark plug, tighten 1/8 -1/4 turn after the spark plug seats to compress the washer.
TROUBLESHOOTING Note: Troubleshooting problems may have similar causes and solutions. PROBLEM The engine will not start No electricity at the AC receptacles POSSIBLE CAUSE SOLUTION Is there fuel in the tank? Refill the fuel tank. Is there enough oil in the engine? Add the recommended oil. Is the spark plug in good condition? Readjust gap and dry the spark plug. Replace it if necessary. Is the fuel reaching the carburetor? Clean the fuel sediment cup.
GENERATOR ASSEMBLY AND MOUNTING The Generator is supplied with a wheel kit. If you want to install the wheel kit on your unit, please follow the instructions below. If you not use the wheel kit, please skip this section. 1. Place the bottom of the generator on a flat, even surface. You may temporarily place the generator on blocks to ease assembly. 2. Attach the support leg to the cradle with bolts (M8x 16) and tighten nuts (M8) (see figure 1 ). 3.
