Frequently Asked Questions - SCGH8500E Simpson

How to start the Simpson SCGH8500E generator?

Ensure the tank has fresh gasoline and the oil level is correct. For electric start, turn the key to START and release once the engine starts. For manual start, set the switch to ON, close the choke if engine is cold, then pull the starter cord firmly. After starting, open the choke.

What engine oil to use?

Use quality 4-stroke engine oil, viscosity SAE 10W-30 for general use. Consult the Honda GX390 engine manual for precise recommendations. Never run the engine without oil.

What type of fuel is recommended?

Use regular unleaded gasoline, clean and fresh, with a minimum octane rating of 87. Do not exceed 10% ethanol (E10). Avoid gasoline containing more than 10% alcohol (E15, E85) as it will damage the engine and void the warranty.

How to test the GFCI outlets?

Start the generator, turn the circuit breakers ON. Press the TEST button on the GFCI outlet: you should hear a click and the LED indicator will light up. Then press RESET to restore power. If the test fails, do not use the generator and have it repaired.

What to do if the generator does not produce power?

First check the circuit breakers: unplug all devices and reset the breakers. If the problem persists, check that the devices and cords are not damaged. If nothing works, contact an authorized service center.

How to store the generator for more than two months?

Drain all fuel from the tank, lines, and carburetor. Change the engine oil. Remove the spark plug, pour 15 ml of new oil into the cylinder, pull the starter twice, then reinstall the spark plug. Clean the generator and store it in a dry, shaded place.

What is the maximum load capacity of the generator?

The generator provides 7000 watts continuous and 8500 watts peak (starting). Do not exceed these values. To calculate the load, add the running watts of all devices; consider startup surge (usually 3 times rated power).

Can I connect the generator to my home's electrical system?

No, never plug the generator directly into a wall outlet (backfeeding). This can electrocute utility workers and damage appliances. Use a transfer switch installed by a qualified electrician if you want to power your home.

How to maintain the electric start battery?

Keep the battery charged at all times; use a smart charger if the generator is inactive. Clean the terminals and check the electrolyte level if accessible. Replace the battery if it no longer holds a charge.

Where to find the serial number and after-sales service?

The model number and serial number are on the generator's data label. For any questions or repairs, contact Simpson customer service at 1 877 362-4271 or by email at [e-mail].

ELECTROCUTION

Do not connect devices with worn, frayed, bare, or otherwise damaged electrical cords to the generator. Electrical shorts caused by damaged wiring can damage the generator and touching live damaged electrical cords or bare wires will cause serious injury or death. To avoid these electrocution hazards, inspect all electrical cords before using them and do not use any cords that are damaged or showing bare wires.

Connecting Generator to the Electrical System of a Building

Do not attempt to backfeed power into your house from the generator. Backfeeding is trying to power your home by plugging the generator into a wall outlet. Backfeeding can damage electrical devices in your home, start an electrical fire, and cause severe injury or death to utility workers and others on your electrical grid.

Using a transfer switch is recommended when connecting a generator directly to a building's electrical system. Connections for a portable generator to a building's electrical system must be made by a qualified electrician and in strict compliance with all national and local electrical codes and laws.

BACKFEEDING

Backfeeding can damage electrical devices in your home, start an electrical fire, and may cause severe injury or death to utility workers and others on your electrical grid. To prevent backfeeding, do not plug the generator into your home's outlets and have a qualified electrician install the generator if used as a back up power source.

Gasoline vapor can build up inside the fuel tank creating pressure. This pressure may increase when the engine is hot from running. Opening the fuel tank under pressure can cause rapid escape of flammable vapors and possible fuel spills that may ignite from contact with hot engine surfaces resulting in burn hazard. To avoid rapidly escaping fuel vapor, always allow the engine to cool for at least two (2) minutes before removing fuel cap and loosen the fuel cap slowly to relieve any pressure in the tank.

NOTICE

GASOLINE STORAGE

It is important to prevent gum deposits from forming in essential fuel system parts, such as the carburetor, fuel filter, fuel hose or tank during storage. Alcohol-blended fuels (also called gasohol, ethanol, or methanol) attract moisture, which leads to separation and formation of acids during storage. Acidic fuel and gum deposits can damage the engine's fuel system while in storage. Effects of old, stale, or contaminated fuel are not covered under warranty.

NOTE: Using a fuel stabilizer when storing gasoline will help prevent problems related to ethanol alcohol in outdoor power equipment engines. Always follow the instructions provided by the fuel stabilizer manufacturer to mix and use correctly.

NOTICE

DO NOT OVERFILL FUEL TANK

Overfilling the fuel tank can result in carbon canister damage (if equipped), poor engine performance, and void the warranty. To avoid damaging the carbon canister, poor engine performance, and voiding the warranty, do not fill the fuel tank above the maximum level.

1. Check fuel with generator on a level surface with the engine off.
2. Read fuel gauge (if equipped) and fill fuel tank if needed. For fuel gage location see the COMPONENT LOCATION section of this manual.
3. Do not use gasoline that is older than 30 days. Use only clean and fresh regular unleaded gasoline with a minimum octane rating of 87. Do not mix oil with gasoline. Do not use gasoline that contains more than 10% ethyl alcohol. E15, E20, and E85 are not approved fuels and should not be used.
4. Do not to fill the fuel tank above the maximum fuel level to allow room for fuel expansion. For fuel capacity see the SPECIFICATIONS section of this manual.

1. Allow the engine to warm up and the idle to stabilize before connecting any devices or turning the idle control switch on.

ELECTROCUTION

Do not connect devices with worn, frayed, bare, or otherwise damaged electrical cords to the generator. Electrical shorts caused by damaged wiring can damage the generator, and touching live damaged electrical cords or bare wires will cause serious injury or death. To avoid these electrocution hazards, inspect all electrical cords before using them and do not use any cords that are damaged or showing bare wires.

Ground Fault Circuit Interrupt (GFCI) (if equipped)

Your generator may be equipped with ground fault circuit interrupting (GFCI) receptacles. The purpose of these devices are to protect you from electrical shock in the instance where an electrical fault is located within your connected device(s).

The GFCI monitors the amount of current flowing to and returning from your connected device. Should the amount of current returning be lower than the amount flowing to the device, the GFCI will “trip”, instantly stopping the flow of electricity. Should the GFCI continuously trip when a device is connected, this is an indication that an electrical fault is located within the device and it should be serviced by an qualified electrical technician before further usage. It is imperative that you test the GFCI unit(s) each time the generator is to be used.

Testing the GFCI receptacle(s)

1. Start the generator as indicated on pages 25 and 26.
2. Turn the circuit breaker(s) ON if they are in the OFF position.
3. Press the TEST button (1) on the GFCI receptacle(s). You should hear a "click" or "snap" sound and the LED indicator (2) will illuminate, (if equipped).
4. Press the RESET button (3) to energize the receptacle; the LED will go dark.
   Should the above test fail, discontinue use of the generator until it can be serviced by a qualified service technician.

Connecting Electrical Devices

1. Allow the engine to warm up and the idle to stabilize before connecting any devices.
2. Inspect power cord for damage before using. Do not connect any electrical devices with cords or plugs showing signs of damage from crushing, cutting, or heat, or other. Never use cords that are coiled; always uncoil cords before using.
3. Make sure electrical devices are off before connecting them to the generator.

FIRE HAZARD

DO NOT use extension cords in the following conditions:

Missing ground pin Spliced Coiled Frayed Overloaded

Generator Load Capacity

1. Before connecting any devices, you must make sure your generator can supply enough rated (running watts) and starting (surge watts) for the electrical devices you wish to power. Exceeding the capacity of generator can damage the generator and/or electrical devices connected to it. Follow the instructions in this section to be sure you do not exceed the maximum output of the generator.
2. Calculating Device Wattage Requirement: Every electrical device has a stated amount of power it needs to operate correctly. Expressed in watts, the power requirement can vary widely depending on the device. To find the wattage, first look in the owners manual of the device. If you do not have the manual, look for a nameplate on the device itself. Many will give you the wattage, but some may only indicate the current requirement (amperage). To find the wattage, simple multiply the current by the operating voltage. For example, a saw has a current requirement of 5.5 amperes at 120 volts. Multiplying 5.5 by 120 gives a wattage of 660.
3. Understanding Device Surge: Devices with inductive loads (motors, transformers, ballasted lights) require more power to start than they require to run. Called surge watts, this extra amount of starting power may only last a second or two as the device powers up, but it must be considered to avoid exceeding the generator's maximum starting output. Surge watts are typically three (3) times higher than the required running watts. For example, a 800-watt motor will require about 2400 watts to start.
4. To power multiple devices at the same time you will first need to be sure the surge from all the devices you wish to power does not exceed the maximum starting watts the generator can provide. Second, you must add up all the device running watts and make sure the total does not exceed the maximum running wattage the generator can provide.
5. Refer to the GENERATOR LOAD CHART in this manual for estimated running watts of common electric devices.

NOTICE

CLEANING

Water can damage the generator windings and other components if allowed to enter through cooling slots or other holes. Damage caused by water intrusion is not covered under warranty. To avoid damaging the generator, do not use a pressure washer, garden hose, or any other sources of running water to clean the generator, and never submerge the generator in any liquids.

Battery Maintenance (Electric Start Models Only)

Batteries slowly lose strength when sitting idle through a process called self-discharge. If a battery is allowed to discharge past a certain point, it cannot be recharged and must be replaced. Therefore, it is best to keep the battery fully charged at all times to achieve maximum service life.

Because batteries for the electric start generator models covered in this manual are sold separately, and because there are different styles of batteries available, it is always best to follow the battery manufacturer's recommendations when handling, charging, storing, servicing, or replacing a battery.

EXPLOSIVE GAS

Batteries produce hydrogen gas while charging. If exposed to an ignition source, hydrogen gas can explode possibly causing property damage, serious injury and/or death. To avoid a hydrogen gas explosion, charge batteries in a well-ventilated place away from open flames, sparks, or any other sources of ignition.

ACID

Batteries contain sulfuric acid. Sulfuric acid is highly corrosive. Contact with skin can cause severe burns; contact with eyes can cause permanent blindness; and accidental ingestion can cause death. To avoid contact with sulfuric acid, always wear protective equipment when handling batteries. If acid contacts skin, rinse the area with cool water for 10-15 minutes. Immediately remove contaminated clothing and rinse the underlying skin with cool water for 10-15 minutes.

Engine Idle Adjustment

The engine idle speed is set at the factory and should not require user adjustment. Tampering with the governor can damage your engine and/or generator and will void the warranty.

IDLE ADJUSTMENT

Improper adjustment of the engine idle speed can damage you engine and/or generator set and will void the warranty. Any inspection and or adjustment of the engine idle should be done by an authorized service center. Tampering with or modifying the engine speed governor can damage you engine and/or generator set and will void the warranty.

MODIFICATION

The generator and engine are factory set to supply the correct frequency and voltage when running. Tampering with the factory governors and adjustments could damage the generator and will void your warranty. To avoid damaging the engine or generator set, do not modify the generator settings or not adjust the engine speed.
