Control Panel Functions

Fuel Selector Switch

Use the switch to select between [GAS] and [LPG] (Propane) fuel sources.

USB Power Outlet

The generator offers a convenient (5V DC 2.1A) [USB Power Outlet] to allow charging of USB chargeable devices like Tablets, MP3 players, GPS, Digital Cameras and other USB chargeable devices.

Indicator Lights

• Oil Warning Indicator Light: When the oil falls below the minimum level, the [Oil Warning Indicator Light] comes on and the engine stops automatically. The engine will not start until the correct volume of oil is in the crankcase.
• Engine Overload Indicator Light: If the [Engine Overload Indicator Light] comes on, the generator's wattage / amperage capacity has been exceeded by connected electrical devices or by a power surge. When this occurs, the green AC Pilot Indicator Light will go off. The engine will continue to run, but the red Engine Overload Indicator Light will stay on and power will no longer be supplied to connected electrical devices.
• AC Pilot Indicator Light: The green [AC Pilot Indicator Light] comes on when the engine starts and generates power.

Note: The engine overload indicator light may turn on for a few seconds when attaching a load due to a power surge. This is normal.

How to Correct Overload:

1. Disconnect any electrical devices then stop the engine.
2. Reduce the total wattage of connected electrical devices until it is within the generator's rated output.
3. Inspect the Air Inlet and Control Panel for any blockage. Remove blockage if found.
4. Restart Engine.

CO Sensor

The [CO Sensor] monitors for the accumulation of poisonous carbon monoxide gas around the generator when the engine is running. If increasing levels of CO gas are detected, the [CO Sensor] automatically shuts down the engine. The [CO Sensor] will also detect the accumulation of carbon monoxide from other fuel burning sources used in the area of operation. For example, if the exhaust of fuel burning tools is pointed at a [CO Sensor]-equipped generator, a shut-off may be initiated due to rising CO levels. This is not an error; hazardous carbon monoxide has been detected. Move and redirect any additional fuel burning sources to dissipate carbon monoxide away from personnel and occupied buildings.

Note: Remote start-equipped generators must be restarted with the [START/STOP Button] on the control panel after an automatic shut-down occurs. Generators are intended to be used outdoors, far from occupied buildings and the exhaust pointed away from personnel and buildings. If misused and operated in a location that results in the accumulation of CO, like in a partially enclosed area, the [CO Sensor] shuts off the engine, notifies the user with a RED indicator light, and directs the user to read the Action Label for steps to take. The [CO Sensor] DOES NOT replace carbon monoxide alarms. Install battery-powered carbon monoxide alarm(s) in your home.

CO SENSOR INDICATOR LIGHTS

• RED: Carbon monoxide accumulated around the generator. After shut-off, the [RED indicator light] in the [CO Sensor] area of the control panel will flash to provide notification that the generator was shut-off due to an accumulating CO hazard. The [RED light] will flash for at least five minutes after a CO shut-off. Move the generator to an open, outdoor area far away from occupied spaces with exhaust pointed away. Once relocated to a safe area, the generator can be restarted. Introduce fresh air and ventilate the area where the generator had shut down.
• YELLOW: A [CO sensor system fault] occurred. When a system fault occurs, the generator is automatically shut down and the [YELLOW indicator light] in the [CO auto-shutoff] area of the control panel will flash to provide notification that a fault has occurred. The [YELLOW light] will flash for at least five minutes after a fault. The generator can be re-started, but may continue to shutoff. A [CO sensor fault] can only be diagnosed and repaired by an authorized Pulsar service center.

AC Circuit Breaker

When the [AC Circuit Breaker] is in the [Circuit Breaker ON (I)] position, the generator is able to supply power to connected electrical devices. When the [AC Circuit Breaker] shifts to the [Circuit Breaker OFF (O)] position, the generator will no longer supply power. The [AC Circuit Breaker] automatically shifts to the [Circuit Breaker OFF (O)] position when connecting electrical devices to the generator that exceed the generator's rated AC output. If the [AC Circuit Breaker] shifts to the [Circuit Breaker OFF (O)] position, reduce the load of connected electrical device until the load is within rated AC output. To re-establish power, shift breaker to the [Circuit Breaker ON (I)] position.

Engine Economy Control

• When the [Economy Switch ON] is in the "ON" position, the economy control unit automatically determines the generator's proper engine speed based on the connected electrical load. This results in superior fuel economy and reduces noise.
• When the [Economy Switch OFF] is in the "OFF" position, the engine will maintain a nominal speed of 3,100 r/min.

Note: The economy switch must be moved to the "OFF" position when using electrical devices that require a large starting current, such as an air compressor.

Parallel Connections

Located just above the [Ground Terminal], the generator's [Parallel Connection Ports] enable a user to run two PG4500BiSRCO generators simultaneously. This feature requires special cables and a parallel kit. When operating generators in parallel, the rated output is 7.4kVA and the rated output is 61.6A/120VAC. To operate generators in parallel consult a PULSAR dealer for a PARALLEL OPERATION CABLE KIT.

⚠️ WARNING! Never connect generators that are different models.

• Engine Oil Quantity: 0.6L (20.2 oz)

CAUTION! Do not tilt generator when adding oil. This could result in overfilling or under filling which could damage the engine.

CAUTION! Ensure no foreign matter enters the crankcase.

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. High altitude performance can be improved by specific modifications to the carburetor. If you always operate your generator at altitudes above 5,000 feet (1,500 meters), have your dealer perform this carburetor modification. This engine, when operated at high altitude with the carburetor modifications for high altitude use, will meet each emission standard throughout its useful life. Even with carburetor modification, engine horsepower will decrease about 3.5% for each 1,000-foot (300 meter) increase in altitude. The effect of altitude on engine power will be greater than this if no carburetor modification is made.

Air Filter

A dirty air filter will reduce the life span of the engine, make it difficult to start the engine, and reduce the unit's performance. Replace with new Air Filter annually.

• To clean, remove the screws then remove left outer casing.
• Turn the [spring latches] to lift then open air filter cover.
• Remove the pleated paper filter.
• Blow the dust away with a compressed air.
• Reinsert the pleated paper filter into the air filter case.

CAUTION! Do not run the generator without reinstalling the foam element or excessive piston and cylinder wear may result, or excessive engine wear may result.
