PREPARING THE GENERATOR FOR USE
USING THE GENERATOR FOR THE FIRST TIME
If you are using the generator for the first time, there are a few steps you must take to prepare it for
operation.
Step 1- Add oil
The generator requires engine oil to operate properly. The generator, when new from the package,
contains no oil in the crankcase. You must add the proper amount of oil before operating the
generator for the first time. This amount, which is equal to the oil capacity of the engine crankcase,
can be found on the chart in figure 1. When filling the engine with oil in the future, please refer to this
chart.
Engine Oil Capacity 12 fluid oz.
Figure 1- Generator Oil Capacity
CAUTION:
 Do not apply engine oil with additives or
2-stroke gasoline engine oil, which may
shorten the engine’s service life.
 Engine oil recommended: SAE 10W-30. As
viscosity varies with regions and temperatures,
so the lubricant has to be selected in accordance
with our recommendation.
To add oil, follow these steps:
1. Make sure the generator is on a level surface.
2. Unscrew the oil filler/dipstick cap from the engine as shown in figure 2.
3. Using a funnel, add the appropriate amount of oil, as found in figure 1, into the crankcase. You
will know the crankcase is full when the oil level has reached the lower lip of the opening you
have just poured the oil into (see figure 3).
4. Replace oil filler cap.

SUBSEQUENT USE OF THE GENERATOR
If this is not your first time using the generator there are still steps you should take to prepare it for
operation.
IMPORTANT: At this point you should be familiar with the procedures described in the first
portion of this section entitled "Using the Generator for the First Time." If you have not yet
read this section, go back and read it now.
Step 1- Check the oil
The generator is equipped with an automatic shutoff to protect it from damage due to low oil.
Nonetheless, you should check the oil level of the engine before each use to ensure that the engine
crankcase has a sufficient amount. To check the oil level:
1. Make sure the generator is on a level surface.
2. Unscrew the oil filler/dipstick cap.
3. With a dry cloth, wipe the oil off of the stick on the inside of the cap.
4. Insert the dipstick as if you were replacing the cap and then remove again. There should now
be oil on the stick. If there is no oil on the stick, or oil only at the very end of the stick, you
should add oil until the engine crankcase is filled (see "Adding Oil" portion of the
"Maintenance" section).
5. Be sure to replace cap when finished checking oil.
NOTE: The oil capacity for your generator can be found in the "Specifications" section of this manual.
Step 2 - Check the Gas Level
Before starting the generator, check to see that there is sufficient gasoline in the gas tank. The fuel
gauge on top of the generator will indicate the gas level in the tank. Add gas if necessary according to
the steps in the portion of the "Maintenance" section.
WARNING: Gasoline and gasoline fumes are highly flammable.
 Do not fill tank near an open flame.
 Always allow engine to cool for several minutes before refuelling.

.
Once you have allowed the engine to run for several minutes, you may connect electrical devices to
the generator.
AC USAGE
You may connect electrical devices running on AC current according to their wattage requirements.
The chart in figure 9 shows the rated and surge wattage of your generator according to its model
number.
The rated wattage corresponds to the maximum wattage the generator can output on a continuous
basis.
The surge wattage corresponds to the maximum amount of power the generator can output for a short
period of time. Many electrical devices such as refrigerators require short bursts of extra power, in
addition to the rated wattage listed by the device, to stop and start their motors. The surge wattage
ability of the generator covers this extra power requirement.
Model Number Rated (Running) Wattage Surge Wattage
55-0343-4 1050 1350
Figure 9 - Generator Wattage by Model Number
The total running wattage requirement of the electrical devices connected to the generator should not
exceed the rated wattage of the generator itself. To calculate the total wattage requirement of the
electrical devices you wish to connect, find the rated (or running) wattage of each device. This number
should be listed somewhere on the device or in its instruction manual. If you cannot find this wattage,
you may calculate it by multiplying the Voltage requirement by the Amperage drawn:
Watts = Volts × Amperes

Figure 10 - Estimated Wattage Requirements of Common Electrical Devices.
Once you have found the rated wattage requirement of each electrical device, add these numbers to
find the total rated wattage you wish to draw from the generator. If this number exceeds the rated
wattage of the generator, DO NOT connect all these devices. Select a combination of electrical
devices which have a total rated wattage lower than or equal to the rated wattage of the generator.
CAUTION - The generator can run at its surge wattage capacity for only a short time. Connect
electrical devices requiring a rated (running) wattage equal to or less than the rated wattage of
the generator. Never connect devices requiring a rated wattage equal to the surge wattage of
the generator.
NOTE: The above wattage figures are estimates. Try to check the wattage listed on your electrical
device before consulting this chart.
Once you have determined what electrical devices you will be powering with the generator, connect
these devices according to the following procedure:
1. Plug in each electrical device with the device turned off.
a. NOTE: Be sure to attach appliances to the correct receptacle (outlet). Connect
standard 120 Volt, single phase, 60 Hz loads only to the 120 Volt receptacle.
b. Connect 120/240 Volt, single phase, 60Hz loads with NEMA L14-30 plug only to the
120/240 Volt receptacle. See Figure 11 for a depiction of each of these receptacles.
2. Switch the circuit breaker to the "ON" position.
3. Turn on the connected electrical devices in the order of the amount of power they require
14

beginning with the device with the highest rated Wattage requirement.
CAUTION: Do not connect 50Hz or 3-phase loads to the generator.

Never clean your generator with a bucket of water or a hose. Water can get inside the working parts of
the generator and cause a short circuit or corrosion.
Checking the Oil
The generator is equipped with an automatic shutoff to protect it from running on low oil.
Nonetheless, you should check the oil level of the generator before each use to ensure that the
generator crankcase has a sufficient amount. To check the
oil level:
1. Make sure the generator is on a level surface.
2. Unscrew the oil filler/dipstick cap (see figure 14).
3. With a dry cloth, wipe the oil off of the stick on the
inside of the cap.
4. Insert the dipstick as if you were replacing the cap
and then remove again. There should now be oil on the stick. Figure 14 - Checking the Oil
If there is no oil on the stick, or oil only at the very end of the stick, you should add oil until the
engine crankcase is filled. See "Changing/ Adding Oil" in this section.
5. Be sure to replace cap when finished checking oil.
Changing/ Adding Oil
You should check the oil level of your generator according to the maintenance schedule in figure 13.
When the oil level is low you will need to add oil until the level is sufficient to run the generator.
The oil capacity of your generator engine is listed in figure 15.
Engine oil capacity 12 Fluid oz.
Figure 15 - Engine Oil Capacity.
It is only necessary to drain the oil from the crankcase if it has become contaminated with water or dirt.
In this case, you can drain the oil from the generator according to the following steps:
1. Place a bucket underneath the generator to catch oil as it drains.
2. Using a 10 mm hex wrench, unscrew the oil drain plug, which is located on the crankcase
underneath the oil filler/dipstick cap (see figure 16). Allow all the oil to drain from the generator.
3. Replace the oil drain plug and tighten with a 10 mm hex wrench.
To add oil to the crankcase, follow these steps:
1. Make sure the generator is on a level surface.
2. Unscrew the oil filler/dipstick cap from the engine as shown in figure 14 above.
3. Using a funnel, add high detergent motor oil to the crankcase. We recommend SAE 10W30
motor oil for general use. When full, the oil level should come close to the top of the oil fill
opening (see figure 17).
17

NOTE: Never dispose of used motor oil in the trash or down a drain. Please call your local
recycling center or auto garage to arrange oil disposal.
Air Cleaner Maintenance
Routine maintenance of the air cleaner helps maintain proper airflow to the carburetor.
Occasionally check that the air cleaner is free of excessive dirt.
1. Unscrew the bolt at side of the air cleaner cover (see figure 18).
2. Remove the sponge-like element from the casing.
3. Wipe the dirt from inside the empty air cleaner casing

The spark plug is important for proper engine operation. A good spark plug should be intact, free of
deposits, and properly gapped. To inspect your spark plug:
1. Pull on the spark plug cap to remove it.
2. Unscrew the spark plug from the generator using the spark plug wrench included with this
product (see figure 20).
3. Visually inspect the spark plug. If it is cracked or chipped, discard and replace with a new spark
plug. We recommend using a F6RTC spark plug such as NGKBPR5ES.
4. Measure the plug gap with a gauge (see figure 21). The gap should be 0.7-0.8 mm
(0.028-0.031 in).
5. If you are re-using the spark plug, use a wire brush to clean any dirt from around the spark plug
base and then re-gap the spark plug.
6. Screw the spark plug back into its place on the generator using the spark plug wrench.
