FLASHING YELLOW LIGHT: Carbon monoxide sensor malfunction. Sensor needs service. Do not use the Generator until the sensor is working properly. For technical questions, please call 1-888-866-5797.

Connecting Electrical Loads

Familiarize yourself with the engine controls, power panel and how to start the engine before using the Generator. Calculate the wattage of the products you will use with the Generator and verify that the Generator can handle the total load.

Connect only properly wired plugs to the Generator.
A plug that is spliced onto a different cord may be hazardous.
Only a qualified electrician should wire a plug onto a cord.

Never exceed the rated capacity for this Generator, as serious damage to the Generator and/or appliances, tools, and equipment could result from an overload. Starting and running wattage requirements should always be calculated when matching this Generator's wattage capacity to the appliance, tool, or equipment.

Use the DC12 V Receptacle to power 12 VDC equipment.

TO PREVENT SERIOUS INJURY: Do not charge batteries without a proper charge controller. Do not overcharge.

Connect the items that require the most wattage first.
Connect "inductive" load appliances, tools, and equipment next. Inductive loads are small hand tools and some small appliances.
Connect any lights next.
Voltage sensitive appliances, tools, and equipment should be the last to be connected to the Generator. Plug voltage sensitive items such as TVs, DVD players, microwaves, and cordless telephones into a UL Listed voltage surge protector (not included). Then, connect the surge protector into the Generator.

Failure to connect and operate appliances, tools, and equipment in this sequence can cause damage to the Generator, appliances, tools, and equipment and will void the Warranty of this Generator.

Note: If Engine speed or voltage fluctuates with a load below the Generator's running watts, move the Engine Choke Lever to the "HALF-CHOKE" position.

IF ANY CIRCUIT BREAKERS TRIP CHECK THE FOLLOWING:

Make sure that ALL circuit breakers are reset before starting the Generator again.
Adjust the plugs so the loads are shared across outlet circuits.

To achieve rated output from the Generator, distribute loads over outlets.

Calculating Total Wattage of Devices Used with the Generator

Before using the Generator, check that the products you want to plug into the unit are below the rated and maximum wattage ratings of the Generator. Use the Wattage Calculation Table below, and the watts listed on your products, to help calculate multiple wattage totals.

To use the table

Add up the Running Watts for all items you would like to use at any given time
Make sure that this total is under the 1,400 running wattage of the Generator.
Find the single highest starting watts for the selected items and add to the total.
Make sure that this total is under the 1,800 max. starting wattage of the Generator.
Plug in and turn on products from largest wattage to smallest.

Wattage Calculation Table

Equipment	Running Watts
Total Running Watts (must be less than 1,400)
Largest Additional Start-up Watts
Total Startup Watts needed for all loads (must be less than 1,800)

Example

Equipment	Running Watts
Microwave (1,000 +200)	1,000
Television (400 + 0)	400
Box Fan (200 + 200)	200
Hand Drill (600 + 600)	600
Total Running Watts (must be less than 1,400)	2,200
Largest Additional Start-up Watts	600
Total Startup Watts needed for all loads (must be less than 1,800)	2,800

A generator that is rated more than the minimum required max. starting watts will last much longer than a generator that only supplies the exact watts needed.

To Calculate Wattage
Volts and amps can be multiplied together to get watts (volts x amps = watts).

To Calculate Additional Start-Up Watts (If They Are Not Listed)
For equipment with a motor: Use the rated watts amount as an estimate of additional Start-up Watts.

For most lights or heaters: there are no additional start-up watts.

If needed, fill the Fuel Tank to about 1 inch under the fill neck with 87 octane or higher unleaded gasoline that has been treated with a fuel stabilizer additive. Follow fuel stabilizer manufacturer's recommendations for use.
Replace the Fuel Cap.
Wipe up any spilled fuel and allow excess to evaporate before starting engine.
To prevent FIRE, do not start the engine while the smell of fuel hangs in the air.

Engine Oil Change

Oil is very hot during operation and can cause burns. Wait for engine to cool before changing oil.

Make sure the engine is stopped and is level.
Close the Fuel Valve.
Place a drain pan (not included) underneath the crankcase's drain plug.
Remove the drain plug and, if possible, tilt the crankcase slightly to help drain the oil out. Recycle used oil.
Replace the drain plug and tighten it.
Clean the top of the Dipstick and the area around it. Remove the Dipstick by threading it counterclockwise, and wipe it off with a clean lint free rag.
Add the appropriate type of oil until the oil level is at the full level. SAE 10W-30 oil is recommended for general use.

Note: Do not thread the dipstick in when checking the oil level.

The SAE Viscosity Grade chart shows other viscosities to use in different average temperatures.

Thread the dipstick back in clockwise.

NOTICE: Do not run the engine with too little oil. Engine will not start with low or no engine oil.

Air Filter Element Maintenance

Remove the air filter cover and the air filter elements and check for dirt. Clean as described below.
Cleaning:

For "paper" filter elements: To prevent injury from dust and debris, wear ANSI-approved safety goggles, NIOSH-approved dust mask/respirator, and heavy-duty work gloves. In a well-ventilated area away from bystanders, use pressurized air to blow dust out of the air filter. If this does not get the filter clean, replace it.
For foam filter elements: Wash the element in warm water and mild detergent several times. Rinse. Squeeze out excess water and allow it to dry completely. Soak the filter in lightweight oil briefly, then squeeze out the excess oil.

Install the cleaned filter. Secure the Air Cleaner Cover before use.

Spark plug Maintenance

Disconnect spark plug cap from end of plug. Clean out debris from around spark plug.
Using a spark plug wrench, remove the spark plug.
Inspect the spark plug: If the electrode is oily, clean it using a clean, dry rag. If the electrode has deposits on it, polish it using emery paper. If the white insulator is cracked or chipped, the spark plug needs to be replaced.

NOTICE: Using an incorrect spark plug may damage the engine. See the Specifications chart for your Generator for the type and gap required.

When installing a new spark plug, adjust the plug's gap to the specification on the Specifications chart. Do not pry against the electrode, the spark plug can be damaged.
Install the new spark plug or the cleaned spark plug into the engine. Gasket-style: Finger-tighten until the gasket contacts the cylinder head, then about 1/2-2/3 turn more.
Non-gasket-style: Finger-tighten until the plug contacts the head, then about 1/16 turn more.

NOTICE: Tighten the spark plug properly. If loose, the spark plug will cause the engine to overheat. If overtightened, the threads in the engine block will be damaged.

Apply dielectric spark plug boot protector (not included) to the end of the spark plug and reattach the wire securely.

Long-Term Storage

When the equipment is to remain idle for longer than 20 days, prepare the Engine for storage as follows:

CLEANING:
Wait for Engine to cool, then clean Engine with dry cloth. NOTICE: Do not clean using water. The water will gradually enter the Engine and cause rust damage. Apply a thin coat of rust preventive oil to all metal parts.
FUEL:
To protect the fuel tank during storage, fill the tank with fresh gasoline that has been treated with a fuel stabilizer additive. Follow fuel stabilizer manufacturer's recommendations for use. Refer to Checking and Filling Fuel.
Aged gasoline that has not been treated with stabilizer ahead of time must be safely drained away and not run through the engine.

burn hazard
To prevent serious injury and fire, close the Fuel Valve before draining the Carburetor.

After closing the Fuel Valve, place an appropriate container under the Carburetor and carefully remove the Drain Bolt from the bottom of the Carburetor Bowl, allowing the fuel to drain completely. Replace the Drain Bolt after draining.

burn hazard
TO PREVENT SERIOUS INJURY FROM FIRE:
Drain the fuel tank in a well-ventilated area away from ignition sources. If the engine is hot from use, shut the engine off and wait for it to cool before draining fuel. Do not smoke.

LUBRICATION:
1. Change engine oil.
2. Clean out area around spark plug. Remove spark plug and pour one tablespoon of engine oil into cylinder through spark plug hole.
3. Replace spark plug, but leave spark plug cap disconnected.
4. Pull Starter Handle to distribute oil in cylinder. Stop after one or two revolutions when you feel the piston start the compression stroke (when you start to feel resistance).
STORAGE AREA:
Cover and store in a dry, level, well-ventilated area out of reach of children. Storage area should also be away from ignition sources, such as water heaters, clothes dryers, and furnaces.

NOTICE: During extended storage periods the Engine must be started every 3 months and allowed to run for 15 – 20 minutes or the Warranty is VOID.

AFTER STORAGE:
Before starting the Engine during or after storage, keep in mind that untreated gasoline will deteriorate quickly. Drain the fuel tank and change to fresh fuel if untreated gasoline has been sitting for a month, if treated gasoline has been sitting beyond the fuel stabilizer's recommended time period, or if the Engine does not start.
