Warnings • • • • • • • • • • • • • • • • Exhaust contains poisonous carbon monoxide. Do not operate the generator in a confined environment. Only use outdoors, away from open doors, windows or vents. The muffler becomes extremely hot during operation, and remains hot for a while after stopping the engine. Be careful not to touch the muffler while it is hot. Let the engine cool before storing the generator indoors. The engine exhaust system will be heated during operation and will remain hot immediately after stopping the engine. To prevent scalding, pay attention to the warning labels on the generator. Do not connect other cables to receptacles during use or use a special jack as it may cause electric shock. Fuel is extremely flammable, and is even explosive under certain conditions. Refuel unit in a ventilated area with the engine stopped. Keep away from cigarettes, smoke and sparks when refuelling the generator. Always refuel in a well ventilated location. Connecting the unit to a building electrical system as a standby power source must be performed by a qualified electrician. The connection must isolate the generator from utility power, and must comply with all applicable laws and electrical codes. Improper connections to a building's electrical system can allow electrical current from the generator to backfeed into the utility lines. Such backfeed may electrocute utility company workers or others who contact lines during a power outage, and the generator may explode or catch fire when utility power is restored. To avoid accidents and equipment damage, check the generator every time before starting the engine. Keep the generator at least 1 meter away from other equipment during operation. Keep the generator horizontal when running. If the generator is tilted, it may cause fuel spillage.

Read the labels and safety notes and precautions described in the manual carefully. Avoid Burns Label Ventilation Label Avoid Fire Label Primer Bulb Label Parameter Label EPA Label EPA Label 3 Pre-operation Checks • • • Be sure to check the generator is on a level surface with the engine stopped. Check the engine oil level. Using 2-stroke engine oil could shorten the engine's service life. Use a premium quality 4-stroke engine oil. Checking the Oil • • Loosen the cover screw and remove the left side maintenance cover. Remove the oil filer cap, then wipe the dipstick with a rag. Check the oil level by reinserting the dipstick into the filler hole without screwing it in. If the oil level is below the end of the dipstick, refill up to the top of the oil filler neck. Note: The Oil Alert System will automatically stop the engine before the oil level falls below the safe limit, however to avoid the inconvenience of an unexpected shut-down, it is still advisable to visually inspect the oil level regularly. Dipstick Lowest oil level allowed 4 Checking the Fuel Level • • Turn the fuel cap lever to the “OFF” position before transporting. Use unleaded automotive fuel. Note: DO NOT use any fuels containing alcohol. Fuel system damage or engine performance problems resulting from the use of fuels that contain alcohol are not covered by warranty. Fuel Cap Open • • • • • • • • • • Never use an oil/petrol mixture or dirty fuel. Avoid getting dirt, dust or water in the fuel tank. After refuelling, tighten the fuel filler cap securely. Petrol is extremely flammable under certain conditions. Refuel in a well-ventilated area with the engine stopped. Do not smoke or allow flames or sparks in the area where the engine is refuelled or where petrol is stored. Do not overfill the fuel tank. After refuelling, make sure that the tank cap is closed properly and securely. Be careful not to spill fuel when refilling. Spilled fuel or fuel vapours may ignite. If any fuel is spilled, make sure the area is dry before starting the engine. Avoid repeated or prolonged contact with skin, or the breathing of vapour. KEEP FUEL OUT OF REACH OF CHILDREN Check the Air Cleaner Check the air cleaner element to ensure it is clean and in good working condition. 1. Loosen the cover screw and remove the left side maintenance cover. 2. Press the latch tab on top of the air cleaner body, remove the air cleaner cartridge, then check the element. 3. Clean and replace the element if necessary. Air Cleaner Cartridge Access Panel Screws Air Cleaner Case Screws Access Panel Air Cleaner Element Never run the engine without the air cleaner. Rapid engine wear will result from airborne contaminants such as dust and dirt being drawn through the carburettor and into the engine. It is normal for a little oil to appear under the air filter box if the generator is running for a long period of time or if a lot of oil is in the engine. Wipe up excess oil after each use and after stopping the generator. 5 LCD Display Layout The LCD display will light up after the generator has started up, and will be functioning after 3-5 seconds.

Turn the fuel cap lever fully clockwise to the ON position. Fuel Cap Lever 2. Set the fuel valve to the ON position. Turn the fuel valve knob to the ON position 3. Set the motor switch to the ON position. Engine Switch 4. Pull slightly on the start cord until you feel resistance, then yank hard and swiftly. • • Do not let the start cord retract by itself, but instead guide it back by hand. Hold the carry handle firmly to prevent the generator from falling over when you pull the start cord. Note: A hot motor will not start if there is too much fuel in the cylinder. If this happens, wait for five to ten minutes before trying again. 8 Starting Grip Once the engine has started, allow the engine to run continuously and warm up. If the engine stops and will not restart, check the engine oil level before troubleshooting in other areas. Before using a device once it is connected, switch the ECO switch off. High Altitude Operation At high altitudes, the standard carburettor air/fuel mixture will be excessively rich. Performance will decrease and fuel consumption will increase. High altitude performance can be improved by installing a smaller diameter main fuel jet in the carburettor and readjusting the slow tempo screws. If you always operate the generator at altitudes higher than 1,500m (4,000 feet) above sea level, have a specialist perform these carburettor modifications. Even with suitable carburettor jetting, engine horsepower will decrease by approximately 3.5% for each 300m (1,000 feet) increase in altitude. The effect of altitude on the horsepower will be greater than this if no carburettor modification is made. Note: Operation of the generator at an altitude lower than the carburettor is jetted for may result in reduced performance, overheating and serious engine damage caused by excessively lean air/fuel mixture. Generator Use • • • • • • • • To prevent electric shock from faulty appliances, the generator should be grounded. 2 Connect an electric conductor (cable) of at least 1.5mm between the generator's ground terminal and an external ground source. Connections for standby power to a building's electrical system must be made by a qualified electrician and must comply with all applicable laws and electrical codes. Improper connections can allow electrical current from the generator to feedback into the utility lines. Do not exceed the current limit set by any one receptacle. Do not connect the generator to a household circuit. This could cause damage to either the generator, or to electrical appliances in the house. Do not modify or use the generator for any purpose other that what it is intended for. Keep the generator away from other electrical cables or wires such as the distribution network. The DC receptacle can be used while AC power is in use. If you use both at once, ensure you do not exceed the total power for AC and DC. Most appliances require more than their rated wattage for start up. 9 AC Applications Start the engine and make sure that the output indicator light (green) illuminates. Confirm that the appliance to be used is switched off, then plug the appliance in. Overload Indicator Light (Red) Output Indicator Light (Green) Substantial overloading that continuously lights the overload indicator light (red) may damage the generator. Marginal overloading that temporarily lights the overload indicator light may shorten the life of the generator. Be sure that all appliances are in good working order before connecting them to the generator. If an appliance begins to operate abnormally, becomes sluggish or stops suddenly, turn the generator engine switch off immediately. Then disconnect the appliance and examine it for signs of malfunction. Output and Overload Indicators The output indicator light (green) will remain lit during normal operating conditions. If the generator is overloaded, or there is a short in the connected appliance, the output indicator light will go OFF, the overload indicator light (red) will go ON and current to the connected appliance will be shut off. Stop the engine if the overload indicator light goes ON and investigate the overload source. Note: Before connecting an appliance to the generator, check that it is in good working order and that its electrical rating does not exceed that of the generator. Then connect the power cord of the appliance and start the engine. Note: Before sure all equipment is turned off before connecting the power cord. Overload Indicator (Red) Output Indicator (Green) Oil Alarm Indicator When an electric motor is started, both the overload indicator light (red) and the output indicator light (green) may go on together. This is normal and the overload indicator light should go out after about four seconds. If the overload indicator light stays on, contact the Kogan customer support team. 10 Connect the ground terminal. Grounding Mark Start the engine according to the “Starting the Engine” chapter of this manual. Note: If the output indicator light (green) does not light, and the overload indicator light (red) lights up instead, set the engine switch to STOP, stop the engine at once, then start the engine again. Confirm that the equipment to be used is switched off, and insert the plug of the appliance to be used into the AC receptacle. Note: Double check that the equipment to be used is switched off before plugging it in. Equipment to be used will operate suddenly and injuries or accidents may be caused. Switch the equipment on and the output indicator light should light up. In the event of overload, the output indicator light will go out and the overload indicator light will come on. No power will be output, however the engine will not have stopped, so the engine must be stopped by setting the respective engine switch to STOP. Normal operations: output indicator will illuminate (green). When overloaded or short-circuited, overload indicator will illuminate (red). Note: When equipment requires a large starting power, the overload indicator light and the output indicator light may light together for a short time. This is not an abnormality. Once the equipment has started, the overload indicator light will go out and the output indicator light will stay lit.

The DC current will be below 5A if you turn on the smart throttle without AC current output. When charging batteries, a person must always be present to monitor the voltage. Charging must be stopped once the voltage of the batteries is above 16V, or it may cause the battery to explode, causing serious injury or death. Charging Wires • • • • • • • • • To prevent the possibility of creating a spark near a battery, connect the charging cable to the generator first, then to the battery. Disconnect the cable first at the cable. Before connecting charging cables to a battery that is installed in a vehicle, disconnect the vehicles grounded battery cable. Reconnect the vehicles grounded battery cable after the charging cables are removed. This procedure will prevent the possibility of a short circuit and sparks if you make accidental contact between a battery terminal and the vehicles frame or body. Do not attempt to start an automobile engine while the generator is still attached to the battery. The generator may be damaged. Connect the positive battery terminal to the positive charging cord. Do not reverse the charging cords, or you may damage the battery or generator. The battery gives off explosive gases; keep sparks, flames and cigarettes away. Provide adequate ventilation when charging. The battery contains sulphuric acid (electrolyte). Contact with skin or eyes will cause severe burns. Wear protective clothing and a face shield. If electrolyte gets on your skin, flush with water. If electrolyte gets in your eyes, flush with water for at least 15 minutes and call 000. If electrolyte gets swallowed, drink large quantities of water or milk, then follow with milk of magnesia or vegetable oil. Call 000. KEEP OUT OF REACH OF CHILDREN, PETS AND UNTRAINED PERSONS. 12 Starting the Engine • • The DC receptacle may be used while the AC power is in use. An overloaded DC circuit will trip the DC circuit protector. If this happens, disconnect the DC load before pushing in the circuit protector to resume operations. DC Circuit Breaker Oil Alert System The oil alert system is designed to prevent engine damage caused by an insufficient amount of oil. The alert system will automatically shut down the engine (the engine switch will remain in the ON position). If the oil alert system shuts down the engine, the oil alert indicator light (red) will come on when you operate the starter, and the engine will not run. If this occurs, add engine oil.

Install the spark plug carefully by hand to avoid cross threading. 6. After a new spark plug has been seated by hand, it should be tightened ½ turn with a wrench to compress its washer. If a used plug is being reinstalled, it should only require a 1/8 to ¼ turn after being seated. 7. Reinstall the ignition coil rubber boot on the spark plug securely. 8. Reinstall the control panel. Note: the spark plug must be securely tightened. An improperly tightened plug can become extremely hot and may damage the generator. Never use a spark plug with an improper heat range. Never use a spark plug without damping resistance, or it will cause no AC output. Transporting and Storage To prevent spillage when transporting or during temporary storage, the generator should be secured upright in its normal operating position, with the engine switch OFF. The fuel cap vent lever must be turned counter-clockwise to the OFF position. Allow the engine to cool completely before turning the fuel cap vent lever to the OFF position. 18 Transporting the generator • • • • Do not overfill the tank. (There should be NO fuel in the filler neck.) Do not operate the generator while it is in a vehicle. Take the generator out of the vehicle and operate it in a well ventilated area. Avoid a location exposed to direct sunlight when putting the generator in a vehicle. If the generator is left in an exposed vehicle for many hours, the high temperatures inside the vehicle may cause fuel to vapourise, resulting in a possible explosion. Do not drive on a rough road for an extended period of time with the generator on board. If you must travel with the generator on board over rough roads, drain all of the fuel from the generator beforehand. Before storing the unit for an extended period 1. Be sure the storage area is free of excessive humidity and dust. 2. Drain the fuel. Note: fuel is extremely flammable and explosive under certain conditions. Do not smoke or allow flames or sparks in the area. 3. Completely drain the fuel from the tank. Open the fuel valve, start the engine and operate in the idle position until all remaining fuel is gone and the engine stops automatically. Fuel Container 4. Discharge the oil. 5. Remove the spark plug and fill the cylinder with 2cc's of fresh oil. Pull the start motor 3-4 times to discharge the remaining oil, then reinstall the spark plug. 6.
