INTRODUCTION

This product has many features for making its use more pleasant and enjoyable. Safety, performance, and dependability have been given top priority in the design of this product, making it easy to maintain and operate.

DANGER
GROUNDING THE GENERATOR
To avoid the risk of shock or electrocution, the generator must be properly grounded. The nut and ground terminal on the frame must always be used to connect the generator to a suitable ground source. The ground path should be made with #8 size wire. Connect the terminal of the ground wire between the lock washer and the nut, and tighten the nut fully. Connect the other end of the wire securely to a suitable ground source. The National Electric Code contains several practical ways in which to establish a good ground source. If a steel or iron rod is used, it should be at least 5/8 in. diameter, and if a nonferrous rod is used, it should be at least 1/2 in. diameter and be listed as material for grounding. Drive the rod or pipe to a depth of 8 ft. If a rock bottom is encountered less than 4 ft. down, bury the rod or pipe in a trench.

All electrical tools and appliances operated from this generator must be properly grounded by use of a third wire or be “Double Insulated.”
It is recommended to:

Use electrical devices with 3-prong grounded plugs.
Use an extension cord with a 3-pole receptacle and a 3-prong plug at opposite ends to ensure continuity of the ground protection from the generator to the appliance.

Check and adhere to all applicable federal, state, and local regulations relating to grounding specifications. Consult a qualified electrician or service personnel if the grounding instructions are not completely understood or if in doubt as to whether the generator is properly grounded.

DANGER

Carbon Monoxide
Using a generator indoors WILL KILL YOU IN MINUTES. Generator exhaust contains high levels of carbon monoxide (CO), a poisonous gas you cannot see or smell. If you can smell the generator exhaust, you are breathing CO. But even if you cannot smell the exhaust, you could be breathing CO.

Never use a generator inside homes, garages, crawl spaces, or other partly enclosed areas. Deadly levels of carbon monoxide can build up in these areas. Using a fan or opening windows and doors does NOT supply enough fresh air.
ONLY use a generator outdoors and far away from open windows, doors, and vents. These openings can pull in the generator exhaust.

Even when you use a generator correctly, CO may leak into the home. ALWAYS use a battery-powered or battery-backup CO alarm in the home. If you start to feel sick, dizzy, or weak after the generator has been running, move to fresh air RIGHT AWAY. See a doctor. You could have carbon monoxide poisoning.

WARNING
Read and understand all instructions. Failure to follow all instructions listed below may result in electrocution, fire, and/or carbon monoxide poisoning, which will cause death or serious injury.

WARNING
National Electric Code requires generators to be grounded to an approved earth ground. Before using the ground terminal, consult a qualified electrician, electrical inspector, or local agency having jurisdiction for local codes or ordinances that apply to the intended use of the generator.

ELECTRICAL

EXTENSION CORD CABLE SIZE
Refer to the table below to ensure the cable size of the extension cords you use are capable of carrying the required load. Inadequate size cables can cause a voltage drop, which can burn out the appliance and overheat the cord.

ELECTRIC MOTOR LOADS
It is characteristic of common electric motors in normal operation to draw up to six times their running current while start-ing. This table may be used to estimate the watts required to start “Code G” electric motors; however, if an electric motor fails to start or reach running speed, turn off the appliance or tool immediately to avoid equipment damage. Always check the requirements of the tool or appliance being used compared to the rated output of the generator.

EXTENSION CORD
See Figure 1.
The generator is supplied with a 25 ft. 12 GA SJTW 4-conductor 105ºC extension cord. This cord is equipped with an L14-20P twist-lock plug on one end which plugs directly into the corresponding twist-lock receptacle on the control panel of the generator. The opposite end has four 5-20R receptacles that can be used to power individual loads. NOTE: For 120-volt use only. Make sure the loads do not exceed the 20 amp rating of the extension cord. Circuit breaker protection is provided for on the control panel of the generator. The receptacles on the extension cord are color coded with blue and red receptacles. When several loads are powered at the same time, it is best to keep equal loads supplied to each separately colored half if possible. Each half of the connector is capable of sustaining 20 amps of current provided the generator is capable of supplying 4800 watts of power. Check nameplate ratings for total wattage capability of the generator. Make sure the generator can supply enough continuous (running) and surge (starting) watts for the items you will power at the same time. Follow these simple steps.

Select the items you will power at the same time.
Total the continuous (running) watts of these items. This is the amount of power the generator must produce to keep the items running. See the wattage reference chart at right.
Estimate how many surge (starting) watts you will need. Surge wattage is the short burst of power needed to start electric motor-driven tools or appliances such as a circular saw or refrigerator. Because not all motors start at the same time, total surge watts can be estimated by adding only the item(s) with the highest additional surge watts to the total rated watts from step 2.

Example

POWER MANAGEMENT
To prolong the life of the generator and attached devices, it is important to take care when adding electrical loads to the generator. There should be nothing connected to the generator outlets before starting its engine. The correct and safe way to manage generator power is to sequentially add loads as follows:

With nothing connected to the generator, start the engine as described later in this manual.
Plug in and turn on the first load, preferably the largest load you have.
Permit the generator output to stabilize (engine runs smoothly and the attached device operates properly).
Plug in and turn on the next load.
Again, permit the generator to stabilize.
Repeat steps 4 and 5 for each additional load.

Never add more loads than the generator capacity. Take special care to consider surge loads in generator capacity as previously described.

CAUTION
Do not overload the generator’s capacity. Exceeding the generator’s wattage/amperage capacity can damage the generator and/or electrical devices connected to it.

The wattages listed are approximate. Check the tool or appliance for actual wattage.

OPERATION

Carbon Monoxide. Using a generator indoors WILL KILL YOU IN MINUTES.
Generator exhaust contains high levels of carbon monoxide (CO), a poisonous gas you cannot see or smell. If you can smell the generator exhaust, you are breathing CO. But even if you cannot smell the exhaust, you could be breathing CO.
Never use a generator inside homes, garages, crawl spaces, or other partly enclosed areas. Deadly levels of carbon monoxide can build up in these areas. Using a fan or opening windows and doors does NOT supply enough fresh air.
ONLY use a generator outdoors and far away from open windows, doors, and vents. These openings can pull in the generator exhaust. Even when you use a generator correctly, CO may leak into the home. ALWAYS use a battery-powered or battery-backup CO alarm in the home.
If you start to feel sick, dizzy, or weak after the generator has been running, move to fresh air RIGHT AWAY. See a doctor. You could have carbon monoxide poisoning.
Failure to properly ground the generator can result in electrocution, especially if the generator is equipped with a wheel kit. National Electric Code requires generators to be properly grounded to an approved earth ground. Call an electrician for local grounding requirements.
Do not allow familiarity with this product to make you careless. Remember that a careless fraction of a second is sufficient to inflict serious injury.
Do not use any attachments or accessories not recommended by the manufacturer of this product. The use of attachments or accessories not recommended can result in serious personal injury.

APPLICATIONS
This generator is designed to supply electrical power for operating compatible electrical lighting, appliances, tools, and motor loads.

BEFORE OPERATING THE UNIT

Only use OUTSIDE and far away from windows, doors, and vents.
NEVER use it inside a home or garage, EVEN IF doors and windows are open.
Always position the generator on a flat firm surface.
CAUTION
Attempting to start the engine before it has been properly filled with lubricant will result in equipment failure.

CHECKING/ADDING LUBRICANT
See Figure 7.
Engine lubricant has a major influence on engine performance and service life. For general, all-temperature use, SAE 10W-30 is recommended. Always use a 4-stroke motor lubricant that meets or exceeds the requirements for API service classification SJ.
NOTE: Non-detergent or 2-stroke engine lubricants will damage the engine and should not be used.

Unscrew the oil cap/dipstick and remove.
Wipe the dipstick clean and re-seat in the hole; do not re-thread.
Remove the dipstick again and check the lubricant level. The lubricant level should fall between the hatched areas on the dipstick.
If the level is low, add engine lubricant until the fluid level rises to the upper portion of the dipstick.
Replace and secure the oil cap/dipstick.

CHECKING/ADDING FUEL
See Figure 8.

Remove the fuel cap.
Fill the fuel tank to 1 in. below the top of the fuel neck.
Replace and secure the fuel cap.
NOTE: Always use unleaded gasoline with a pump octane rating of 86 or higher. Never use old, stale, or contaminated gasoline, and do not use an oil/gas mixture. Do not allow dirt or water into the fuel tank.

USING FUEL STABILIZER
Fuel gets old, oxidizes, and breaks down over time. Adding a fuel stabilizer (not included) extends the usable life of fuel and helps prevent deposits from forming that can clog the fuel system. Follow the fuel stabilizer manufacturer’s directions for the correct ratio of stabilizer to fuel.

Add stabilizer to fuel tank, then fill with gasoline following previous instructions.
NOTE: Fuel stabilizer and gasoline can be mixed prior to filling the tank by using a gas can or other approved fuel container and shaking gently to combine.
Replace and secure the fuel tank cap.
Start and run the engine for at least 5 minutes to allow the stabilizer to treat the entire fuel system.

OXYGENATED FUELS
Some conventional gasoline are blended with alcohol or an ether compound. These gasoline are collectively referred to as oxygenated fuels. To meet clean air standards, some areas of the United States and Canada use oxygenated fuels to help reduce emissions. If using an oxygenated fuel, make sure it is unleaded and meets the minimum octane rating requirements. Before using an oxygenated fuel, try to confirm the fuel’s contents. Some states/provinces require this information to be posted on the pump. The following are the EPA-approved percentages of oxygenates: Ethanol (ethyl or grain alcohol) 10% by volume. You may use gasoline containing up to 10% ethanol by volume. Gasoline containing ethanol may be marketed under the name “Gasohol.” Do not use E85 fuel. MTBE (methyl tertiary butyl ether) 15% by volume. You may use gasoline containing up to 15% MTBE by volume. Methanol (methyl or wood alcohol) 5% by volume. You may use gasoline containing up to 5% methanol by volume as long as it also contains cosolvents and corrosion inhibitors to protect the fuel system. Gasoline containing more than 5% methanol by volume may cause starting and/or performance problems. It may also damage the metal, rubber, and plastic parts of the generator or your fuel system. If you notice any undesirable operating symptoms, try another service station or switch to another brand of gasoline.

NOTE
Fuel system damage or performance problems resulting from the use of an oxygenated fuel containing more than the percentages of oxygenates stated previously are not covered under warranty.

CAUTION
On a level surface with the engine off, check the lubricant level before each use of the generator.
