SYMBOL MEANINGS (Refer to SAFETY INFORMATION for more details. Page 7) ! Attention! Become alert! Your safety is important! Read the manual before operation. Be careful of poisonous exhaust. Never operate the machine in a closed area. Avoid touching hot surfaces, such as engine and muffler. Ground (earth) terminal. Be sure to ground (earth) the generator. Pg.
SAFETY INFORMATION Do not use in a closed vehicle This generator is not designed for marine-use. Do not modify or use the generator with any component removed. Do not allow children to use the generator. Make sure to move the generator only by the carry handle. ① Handle Do not place any obstacle on the generator. Do not place any obstacle in front of exhaust pipe Do not operate generator on wet or dusty/sandy surface. Operate on hard, dry surfaces only.
HIGHLY FLAMMABLE AND POISONOUS FUEL Always shut the engine when refueling. Never refuel when smoking or near an open flame. Be careful not to spill any fuel on the Engine or muffler when refueling. Do not swallow, inhale fuel vapor, or allow any fuel into your eye. If this occurs, seek medical attention immediately. If you spill fuel on your skin or clothing, wash it immediately with soap and water. When carrying generator, keep machine vertical (upright).
Do not operate the generator in a confined space or when covered with dust cover (or other materials). Ensure the engine and muffler are completely cooled, before covering generator. ELECTRIC SHOCK PREVENTION Never operate generator in rain or snow to avoid electric shock. Never touch the generator with wet hands, or electric shock may occur. Connect the ground line of generator with ground (earth) terminal, and the other end to the ground electrode buried in the ground. ① Ground (earth) terminal Pg.
CONNECTION NOTES Avoid connecting the generator to commercial power socket. Avoid connecting the generator in parallel with any other generator. ① Correct ② Incorrect ! WARNING: Before connecting generator to a building’s electrical system, a licensed electrician must install an isolation (transfer) switch to main fuse box. The switch is the connection point for generator power and allows generator power or main line power to the building.

SMART-THROTTLE SWITCH (ECO-MODE) ① ON - When smart-throttle switch is in ON position, the economic control mode will automatically adjust the engine speed according to the connected load, so as to achieve low fuel consumption and low noise. ② OFF - When smart-throttle switch is in the OFF position, the engine will run at rated speed (5000rpm), regardless of load.
LOW OIL ALARM (YELLOW) If engine oil level falls below the lower level, the low oil alarm will turn on, and the engine will stop automatically. Refill engine oil, otherwise engine will not start. ① Engine Oil Alarm ! NOTE: If engine won’t start, turn the main switch to ON position, then pull the recoil starter. If low oil alarm light flickers for a few seconds, it means engine oil is insufficient. Add engine oil and retry.
4. Restart the engine after checking. ! NOTE: The generator output automatically resets when engine is stopped and then restarted. ! NOTE: The overload indicator light may be ON for a few seconds at first when using electric devices that require a large starting current, such as air conditioner, air compressor, submersible pump, or high-power DC equipment. This is not a malfunction. OUTPUT INDICATOR (GREEN) When the engine is started the output indicator turn ON (Green).
PRE-OPERATION CHECK ! NOTE: Pre-operation checks should be made each time before using generator. FUEL Open fuel tank cap, fill with unleaded fuel to red mark inside fuel filling screen. The recommended fuel is unleaded gasoline #93 octane or above. ! NOTICE: If there is any spilled fuel, use a clean and dry soft cotton cloth to wipe area to avoid corrosion on surface or plastic parts. ! NOTICE: Only use recommened unleaded fuel, as other may cause serious damage on engines inner components.
ENGINE OIL Check the oil level by placing generator on a level surface and inspecting at the oil filter hole. The oil should be level with the Lower edge. Add oil if necessary. ① Lower edge, oil filter hole ! NOTICE: The generator leaves the factory without engine oil. ! NOTICE: Do not tilt the generator when filling engine oil. This may result in overfilling and potential damage to the generator. RECOMMENDED ENGINE OIL A: SAE15W-40 B: SAE10W-30 C: SAE5W-30 ENGINE OIL CAPACITY 300 to 400ml (0.42US qt, 0.
OPERATION INSTRUCTIONS ! WARNING: Always operate generator in a well ventilated area. Never operate generator in a closed in area as it may cause unconsciousness or even death within minutes. ! NOTE: Clean dust, dirt or water off the socket before use. Before starting the engine, do not connect any electrical devices. ! NOTICE: Read PRE-OPERATION CHECK (see page XX) carefully before operation of generator.
2. Turn the main switch to ON position. This turns on the Ignition circuit and allows the fuel to flow. 3. Pull out choke cable button out completely. ① Choke cable button ! NOTE: Choke is not required when starting a warm engine. Set choke back to original position. 4. Pull slowly on the recoil starter handlebar until it is compressing, then pull hard. ! NOTE: Grasp generator by the carry handle firmly to prevent the generator from falling when pulling the recoil starter. 5.
APPLICATION RANGE When using the generator, please make sure total load is under the range of generator rated output, or the generator may be damaged. ! NOTE: The overload alarm indicator ① is on (red) When total watts exceed the application range. (See page 17 for more details.) CTG2500i AC DC Power Factor Rated Output 1.0 2100VA 0.8 1680VA - 96W 12V/8A ! NOTICE: Do not overload. The total load of all electrical appliances must not exceed the supply range of the generator.
