DESCRIPTION

This is a Gasoline Powered Invertor Generator that offers clean power for electronics.

1. ENGINE SWITCH
   The engine switch controls the ignition system.
   To Start generator, turn POWER switch ON. Then the engine can be started by sliding Choke lever to CHOKE then pull Recoil. Allow engine to run for a few seconds
   then slide the Choke Lever to OFF.
   To Stop generator, press POWER switch to STOP. The engine will not run.
2. ECONOMY CONTROL SWITCH
   When the economy control switch is turned “ON”, the economy control unit controls the engine speed according to the connected load. The results are better fuel connection and less noise. (Turn OFF when using less voltage.)
3. LOW OIL ALERT SENSOR
   When the oil level falls below the acceptable level, the engine stops automatically. Unless you refill with oil, the engine will not start again.
4. OVERLOAD INDICATOR LIGHT
   • The overload indicator light flickers when an overload of a connected electrical device is detected. This situation shall not be kept for a long time and it just needs to decrease the loads to its normal range and the overload indicator light will go off. When it is detected the inverter unit overheats, or the AC output voltage decreases, the overload indicator light will come on and the electronic breaker will then activate, stopping power to the generation in order to protect the generator and any connected electric devices. The output pilot light (Green) will be off, the overload indicator light will turn RED, & the engine will stop. It is needed to process as follows:
   (a) Turn off any connected electric devices
   (b) Reduce the total wattage of connected electric.
   (c) Check for blockages in the cooling air inlet, muffler air exhaust pipe opening and the control unit & restart engine.
   The generator AC output automatically resets when the engine is stopped and then restarted. The overload indicator light may come on for a few seconds at first when using electric devices that require a large starting current, such as a compressor or a submergible pump. However, this is not a malfunction.
5. DC CIRCUIT PROTECTOR
   The DC circuit protector turns off automatically when the load exceeds the generator rated output. Reduce the load to within specified generator rated output if the DC circuit protector turns off.
6. FUEL COCK
   The fuel cock is used to supply fuel from the tank to the carburetor.
   Turn ON when getting ready to start the generator. Turn OFF when finished using the generator.
   

CHECK ENGINE FUEL

• Make sure there is sufficient fuel in the tank.
• If fuel is low, refill with unleaded automotive gasoline.
• Be sure to use the fuel filter screen on the fuel filter neck.
• Recommended fuel: Unleaded gasoline.
• Fuel tank capacity: 0.55 Gallon
• Do not refill tank while engine is running or hot.
• Close fuel cock before refueling with fuel.
• Be careful not to admit dust, dirt, water or other foreign objects into fuel.
• Do not fill above the top of the fuel filter or it may overflow when the fuel heats up later and expands.
• Keep open flames away.
  

CHECK ENGINE OIL

Remove side panel, remove oil filler cap and check the oil level. Make sure the oil is at top of Lower Level line (See Figure 2).

• WARNING: The generator has been shipped without engine oil. Fill with oil or it will not start.
• Do not tilt the generator when adding engine oil. This could result in overfilling and damage to the engine
• If oil level is below the lower line, add oil to top of Lower Level line. Screw in the oil filler cap when checking oil level.
• Oil Type: SAE 10W30 Oil capacity: 7.5 ounces

The Grounding Terminal is located on the front of the generator, to the right of the AC Output socket.
GROUND
Ground this generator by tightening the grounding nut against a grounding wire. (See Figure 3) Use a No. 12 AWG (American Wire Gauge) stranded copper wire, which is generally considered an acceptable grounding wire. The other end of this grounding wire should be connected to a copper or brass grounding rod that is driven into the earth. Proper grounding of the generator will help prevent electrical shock in the event of a ground fault condition in the generator or in connected electrical devices. Proper grounding also helps dissipate static electricity, which often builds up in ungrounded devices.

STARTING THE ENGINE

• Before starting the engine, do not connect electric apparatus.
  1. Turn the fuel cock lever to the “ON” position.
  2. Turn the fuel tank cap air vent knob clockwise to the “OPEN” position. Turn the engine switch to the “ON” or “RUN” position.
  3. Turn the choke lever to the “Closed To Start” position.
  4. PUMP the PRIMER button until the glass bowl is full.
  5. Pull the recoil starter handle slowly until resistance is felt. This is the “Compression” point. Return the handle to its original position and pull swiftly. Do not fully pull out the rope. After starting, allow the starter handle to return to its original position while still holding the handle. Grasp the handle firmly to prevent the generator from falling over when pulling the recoil starter.

FEATURES
CO WARNING
ALERT!
Carbon monoxide (also known as CO) can be dangerous for humans and pets. Carbon monoxide poisoning can lead to death in a very short time. It is called “the silent killer” because it is odorless, tasteless and invisible: you may be exposed without knowing it.
This generator features CO WARNING. which will auto-matically shut-off if dangerous levels of CO is detected.
WARNING! IF DANGEROUS CARBON MONOXIDE LEVELS ARE DETECTED, ENGINE WILL SHUTOFF
AUTOMATIC SHUTOFF – YOU
MUST:
MOVE GENERATOR TO AN OPEN, OUTDOOR AREA. POINT EXHAUST AWAY. DON’T RUN GENERATOR IN ENCLOSED AREAS (E.G. NOT IN HOUSE OR GARAGE)
The indicator will light RED and the engine will shutdown if dangerous CO levels are detected. The engine will not restart for 5 minutes. If an error in the carbon monoxide system is detected. the indicator will light YELLOW.
MOVE TO FRESH AIR AND GET MEDICAL HELP IF SICK, DIZZY OR WEAK.
Carbon monoxide (also known as CO) can be dangerous for humans and pets. Carbon monoxide poisoning can lead to death in a very short time. It is called “the silent killer” because it is odorless, tasteless and invisible: you may be exposed without knowing it.
The CO Detection module monitors for the accumulation of poisonous CO gas found in engine exhaust when the generator is running. If CO detector detects increasing levels of CO gas, it automatically shuts off the engine. CO detector only monitors when the engine is running. Generators are intended to be used outdoors, far from occupied buildings and the exhaust pointed away from personnel and buildings. However, if misused and operated in a location that results in the accumulation of CO, like indoors or in a partially enclosed area, CO detector shuts off the engine, notifies the user of what has happened and directs the user to read the instruction action label for steps to take. CO detector is not a substitute for an indoor carbon monoxide alarm.
After a shut-off, a blinking RED light in the CO detector badge on the side of the generator provides notification that the generator was shut off due to an accumulating CO hazard. The RED light will blink for at least five minutes after a CO shut-off. Move the generator to an open, outdoor area and point the exhaust away from people and occupied buildings. Once relocated to a safe area, the generator can be restarted and the proper electrical connections made to supply electrical power. The RED light will stop blinking automatically upon engine re-start. Introduce fresh air and ventilate the location where the generator had shut down.
If a CO detector system fault has occurred and no longer provides protection, the portable generator is shut off automatically and the YELLOW light will blink for at least five minutes in the CO detector badge to notify the user of the fault. The CO detector module can only be diagnosed and repaired by a trained technician at the dealer. The generator can be restarted, but may continue to shut-off.CO detector will detect the accumulation of Carbon Monoxide from other fuel burning sources such as engine powered tools or propane heaters used in the area of operation. For example, if another generator is used and the exhaust is pointed at a CO detector equipped generator, CO detector may initiate a shut-off due to rising CO levels. This is not an error. Hazardous Carbon Monoxide has been detected. The user must take action to move and re-direct these devices to better dissipate Carbon Monoxide far away from personnel and occupied buildings.
