GENERATOR SAFETY WARNINGS

DANGER! CARBON MONOXIDE

Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide (CO). This is a poison 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 partially 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 outside and far away from windows, doors, and vents. These openings can pull in generator exhaust.

Even if 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 may have carbon monoxide poisoning.

WARNING! RISK OF EXPLOSION. HIGHLY FLAMMABLE: This generator may emit highly flammable and

explosive gasoline vapors, which can cause severe burns or even death, if ignited. A nearby open flame can lead to explosion even if not directly in contact with gasoline.

• Do not operate near open flame, heat, or any other ignition source. Do not smoke near the generator.

• Always operate on a firm, level surface.

• Always turn generator off before refueling. Allow generator to cool for at least 2 minutes before removing fuel cap. Loosen cap slowly to relieve pressure in tank.

• Do not overfill fuel tank. Gasoline may expand during operation. Do not fill to the top of the tank. Allow for expansion. Always check for spilled fuel before operating.

• If fuel spills, move the generator at least 30 feet away from the spill and wipe clean any spilled fuel before starting the engine.

• Empty fuel tank before storing or transporting the generator.

WARNING! If this generator is used as a supply for a building’s wiring system, the generator must be in-

stalled by a qualified electrician and connected to a transfer switch as a separately derived system in accordance with all applicable laws and electrical codes and the National Electrical Code, NFPA 70. The generator shall be connected to a transfer switch that switches all conductors excluding the equipment grounding conductor. The frame of the generator shall be connected to an approved grounding electrode.

USING YOUR GENERATOR

CALCULATING THE WATTAGE OF YOUR DEVICE(S)

Connect electrical devices running on AC current according to their wattage requirements. Calculate the total running wattage and starting wattage of the device(s) you wish to connect, and MAKE SURE that they are within the capacity of your generator and the capacity of each individual outlet.

Wattage

Calculation

What this means:

The generator can produce a maximum of 7500W on a continuous basis to supply ongoing power to your electronic devices.

NOTE: Also check the rated amperage for each outlet and make sure not to overload the individual outlets.

Find the wattage information of each device you plan to connect. The information should be

listed on the device or in its instruction manual, or you may refer to page 23, Table 2.

The wattage can be calculated using this equation: Watts = Volts x Amperes

To calculate the total running watts of your devices:

+ Add up the running wattages of all the

device(s) you plan to connect.

= The total running (rated) wattage.

This wattage should NOT exceed the running wattage of 7500W.

It is recommended to maintain a load at or below 6300W (90% of the rated output) to ensure steady voltage output and to prolong the generator’s lifespan.

What this means:

Some devices such as box fans require short bursts of extra power in addition to the rated wattage listed by the device to start their motors.

The generator can produce a maximum wattage of 9500W for a short period of time (seconds) to cover the extra starting power required by your electronic devices.

To calculate the total starting watts of your devices:

+ Add up the total running wattage of all the

device(s) you plan to connect.

+ Add the single highest ADDITIONAL starting wattage out of the device(s) you plan to connect.

= The total starting (surge) wattage.

This wattage should NOT exceed the starting wattage of 9500W.

If any of either of the total calculated running watts or starting watts is higher than the capacity of your generator, adjust the load until both wattage requirements are met. Otherwise you will overload the generator, and cause damage to the engine and your electrical device(s).

• Do not store the generator with fuel inside the tank for more than 2 months - the fuel will go bad.

• Run the generator for at least 20 minutes every month to charge the battery and maximize lifespan.

CLEANING THE GENERATOR

Keep the generator clean to prevent improper operation or machine damage from dirt and debris. Inspect all ventilation openings on the generator. These openings must be kept clean and unobstructed. If the generator becomes dirty, use a damp cloth to wipe exterior surfaces. Use a soft bristle brush to loosen dirt and oil and use a vacuum to pick up loose dirt. Use low pressure air (not to exceed 25 PSI) to blow away dirt.

CAUTION! Never clean the generator when it is running! Never clean with a bucket of water or a hose. Water

can get inside the working parts of the generator and cause corrosion or a short circuit.

NOTE: Failure to properly maintain the generator will void the warranty.

MAINTENANCE

CHECKING / ADDING OIL

Check the oil level before each use and every 8 hours of operation (refer to page 27, Table 4). The oil capacity of the generator engine is 37.2 fl. oz. (1.1 L). Add oil when the oil level is low. For the proper type and weight of oil refer to page 13, Fig. 4. This is a critical step for proper engine starting. The generator is equipped with a low-oil shutdown feature to protect it from running without oil. To check the oil level and/or add oil refer to

"Step 1 - Add / Check Oil" on page 13.

Fig. 18

DRAINING / CHANGING THE OIL

Change the oil according to the Recommended Maintenance

Schedule (refer to page 27, Table 4). Change the oil more often

if operating under heavy load or high ambient temperatures. It is also necessary to drain the oil from the crankcase if it has become contaminated with water or dirt. Changing the oil when the engine is warm allows for complete drainage.

1. Prepare an approved oil-storage container underneath the oil drain bolt next to the oil dipstick to catch the oil as it drains.

NOTE: To avoid possible fuel spills from the carburetor bowl, drain the carburetor (refer to "Draining The Carburetor" on page 29) before draining the oil.

2. Unscrew the oil drain bolt (Fig. 18 - 1) and allow oil to drain from the engine completely.

3. Reinstall the oil drain bolt and tighten it securely. Wipe clean any oil spillage.

4. To add new oil, refer to "Step 1 - Add / Check Oil" on page 13.

NOTE: Never dispose of used engine oil in the trash or down a drain. Please call a local recycling center or auto garage to arrange proper oil disposal.

MAINTENANCE

DRAINING THE CARBURETOR

Drain the carburetor after every use and before storing the generator (refer to page 27, Table 4). Draining the carburetor can help prevent build-up and blockages caused by stagnant fuel inside of the carburetor.

1. Prepare an approved gasoline-storage container under the carburetor to collect drained fuel. Close the fuel valve (Fig. 19).

2. The carburetor can be accessed from the backside of the generator between the engine and air filter. To drain the carburetor, open up the carburetor drain screw (Fig. 20) with a Phillips-head screwdriver and drain out any gasoline that has built up inside.

3. Once the fuel has drained, close the drain screw.

NOTE: Make sure to drain your carburetor before storing the generator for long periods of time.

INSPECTING / CLEANING THE AIR FILTER

Inspect and clean the air filter every 50 hours of operation (refer to page 27, Table 4). Routine maintenance of the air filter helps maintain proper airflow to the carburetor. Occasionally check that the air filter is free of excessive dirt. Clean air filter more frequently in dirty or dusty conditions.

MAINTENANCE

BATTERY MAINTENANCE/STORAGE

The battery (part no.GN9500-059) shipped with the generator has been fully charged. The battery will receive charge when the engine is running. Remember to run the generator once a month for 20-30 minutes to charge the battery. A charged battery will allow you to start the generator using the electric start switch during your next time of need.

If the battery is out of charge, you can still manually start the generator using the recoil start.

IMPORTANT: If the generator is not used for a long period, it is recommended to disconnect the negative battery cable from the battery to protect the battery from losing charge. After disconnecting the cable, cover the free end with an insulator such as electrical tape. You may can also connect the battery to an automatic trickle charger to keep the battery charged.

To reinstall/replace the battery:

1. Disconnect the negative (-) battery terminal first (black wire).

2. Disconnect the positive (+) battery terminal second (red wire).

3. To install a new battery, install the hold down bracket, insert the threaded rod and tighten with M6 nuts.

4. Connect the positive (+) battery terminal (red wire) first. Slide rubber boot over the connection hardware.

5. Connect the negative (-) battery terminal (black wire) second. Slide rubber boot over connection hardware.

TRANSPORTATION & STORAGE

TRANSPORTING THE GENERATOR

To prevent fuel spillage when transporting, be sure to perform the following:

1. Tighten the fuel cap.

2. Flip the engine switch to the OFF position.

3. Drain the fuel tank if possible. Refer to section, “Draining the Fuel Tank.”

4. Keep the generator upright. Never place the generator on its side or upside down - doing so could damage the internal components of the generator and make it difficult to start.

WARNING! Avoid direct sunlight inside a vehicle. If the generator is left in an enclosed vehicle for many

hours, the high temperature could cause the fuel to vaporize and result in a possible explosion.

STORING THE GENERATOR

Shut off the generator and allow the unit to cool to room temperature before storing it. NEVER place any type of storage cover on the generator while it is still hot. Do not obstruct any ventilation openings.

Follow the procedures below for properly storing your generator. We highly recommend running your generator once a month for 20 to 30 minutes. Plug in a small load in to ensure there is proper power output.

For Short Periods (30 to 60 Days):

• Drain the carburetor. Refer to page 29, “Draining the

Carburetor.”

• Disconnect the negative lead from the battery.

• Add fuel stabilizer: Follow the suggested portions and instructions of your preferred stabilizer. Run the engine for 15 to 20 minutes, allowing the fuel stabilizer to mix with the gasoline and circulate through the carburetor, and then top off with fuel. Filling the fuel tank full reduces the amount of air in the tank and helps fight deterioration of fuel.

WARNING! Store the generator upright in a cool and dry location, away from sources of heat, open flames,

sparks or pilot lights.

For Extended Periods (Over 60 Days):

• Disconnect the negative lead from the battery.

• Drain the fuel tank and carburetor (see “Draining the Fuel Tank”). Never store generator with fuel in the tank for more than two months.

• Change the engine oil (see “CHANGING OIL”).
