2.4 HOW TO USE THE GENERATOR
If there are any problems operating the generator, please call the
generator helpline at 1-888-436-3722.
2.4.1 GROUNDING THE GENERATOR
The National Electrical Code requires that the frame and external
electrically conductive parts of this generator be properly
connected to an approved earth ground (Figure 9). Local electrical
codes may also require proper grounding of the unit. For that purpose,
connecting a No. 10 AWG (American Wire Gauge) stranded copper
wire to the grounding lug and to an earth-driven copper or brass
grounding rod (electrode) provides adequate protection against
electrical shock. However, local codes may vary widely. Consult with
a local electrician for grounding requirements in the area.
2.3.2 120/240 VAC, 30 AMP RECEPTACLE
Use a NEMA L14-30 plug with this receptacle (rotate to lock/unlock).
Connect a suitable 4-wire grounded cord set to the plug and to the
desired load. The cord set should be rated for 250 Volts AC at 30
Amps (or greater) (Figure 8).
6
Figure 9 - Grounding the Generator
Proper grounding of the generator will help prevent electrical
shock in the event of a ground fault condition in the generator or in
connected electrical devices. Proper grounding also helps dissipate
static electricity, which often builds up in ungrounded devices.
Page 9
Section 2 – Operation
Portable Generator System
2.4.2 CONNECTING ELECTRICAL LOADS
DO NOT connect 240 Volt loads to 120 Volt receptacles. DO NOT
connect 3-phase loads to the generator. DO NOT connect 50 Hz loads
to the generator.
Let engine stabilize and warm up for a few minutes after starting.•
Plug in and turn on the desired 120 or 240 Volt AC, single phase, •
60 Hz electrical loads.
Add up the rated watts (or amps) of all loads to be connected •
at one time. This total should not be greater than (a) the rated
wattage/amperage capacity of the generator or (b) circuit breaker
rating of the receptacle supplying the power. See "Don't Overload
the Generator".
2.5 DON’T OVERLOAD THE GENERATOR
Overloading a generator in excess of its rated wattage capacity can
result in damage to the generator and to connected electrical devices.
Observe the following to prevent overloading the unit:
Add up the total wattage of all electrical devices to be connected •
at one time. This total should NOT be greater than the generator's
wattage capacity.
The rated wattage of lights can be taken from light bulbs. The rated •
wattage of tools, appliances and motors can usually be found on a
data label or decal affixed to the device.
If the appliance, tool or motor does not give wattage, multiply volts •
times ampere rating to determine watts (volts x amps = watts).
Some electric motors, such as induction types, require about three •
times more watts of power for starting than for running. This surge
of power lasts only a few seconds when starting such motors.
Make sure to allow for high starting wattage when selecting
electrical devices to connect to the generator:
1. Figure the watts needed to start the largest motor.
2. Add to that figure the running watts of all other connected loads.
The Wattage Reference Guide is provided to assist in determining
how many items the generator can operate at one time.
NOTE:
All figures are approximate. See data label on appliance for
wattage requirements.

2.7 BEFORE STARTING THE GENERATOR
Prior to operating the generator, engine oil and gasoline will need to
be added, as follows:
2.7.1 ADDING ENGINE OIL
All oil should meet minimum American Petroleum Institute (API)
Service Class SJ, SL or better. Use no special additives. Select the
oil's viscosity grade according to the expected operating temperature
(also see chart).
Above 40° F, use SAE 30•
Below 40° F and down to 10° F, use 10W-30•
Below 10° F, use synthetic 5W-30•
SAE 30
10W-30
Do not overfill the fuel tank. Always leave room
for fuel expansion. If the fuel tank is over-filled,
fuel can over flow onto hot engine and cause an
explosion.
Use regular UNLEADED gasoline with the generator engine. Do •
not use premium gasoline. Do not mix oil with gasoline.
Clean area around fuel fill cap, remove cap.•
Slowly add unleaded regular gasoline to fuel tank. Fill to bottom of •
screen filter. Be careful not to overfill (Figure 10).
Install fuel cap and wipe up any spilled gasoline. •
Figure 10 - Fuel Tank

2.7.2 ADDING GASOLINE
DANGER
Never fill fuel tank indoors. Avoid spilling
gasoline on hot engine. Allow engine to cool
entirely before adding fuel. Never fill fuel tank
when engine is running or hot. DO NOT light a
cigarette or smoke when filling the fuel tank.
Gasoline is highly flammable and its vapors are
explosive.

Fuel
IMPORTANT: It is important to prevent gum deposits from forming
in fuel system parts such as the carburetor, fuel hose or tank during
storage. Alcohol-blended fuels (called gasohol, ethanol or methanol)
can attract moisture, which leads to separation and formation of acids
during storage. Acidic gas can damage the fuel system of an engine
while in storage. To avoid engine problems, the fuel system should
be emptied before storage of 30 days or longer. See the "Storage"
section. Never use engine or carburetor cleaner products in the fuel
tank as permanent damage may occur.

3.3 GENERAL RECOMMENDATIONS
The warranty of the generator does not cover items that have been
subjected to operator abuse or negligence. To receive full value from
the warranty, the operator must maintain the generator as instructed
in this manual.
Some adjustments will need to be made periodically to properly
maintain the generator.
All adjustments in the Maintenance section of this manual should
be made at least once each season. Follow the requirements in the
"Maintenance Schedule".
NOTE:
Once a year replace the spark plug and replace the air filter. A
new spark plug and clean air filter assure proper fuel-air mixture
and help the engine run better and last longer.
3.3.2 TO CLEAN THE GENERATOR
Use a damp cloth to wipe exterior surfaces clean.•
A soft, bristle brush may be used to loosen caked on dirt, oil, etc.•
A vacuum cleaner may be used to pick up loose dirt and debris.•
Low pressure air (not to exceed 25 psi) may be used to blow away •
dirt. Inspect cooling air slots and openings on the generator. These
openings must be kept clean and unobstructed.
3.3.3 ENGINE MAINTENANCE
DANGER
When working on the generator, always
disconnect negative cable from battery. Also
disconnect spark plug wires from spark plug
and keep wire away from spark plug.
3.3.4 CHECKING OIL LEVEL
See the “Before Starting the Generator” section for information on
checking the oil level. The oil level should be checked before each
use, or at least every eight hours of operation. Keep the oil level
maintained.
3.3.5 CHANGING THE OIL
Change the oil every 100 hours. If running this unit under dirty or dusty
conditions, or in extremely hot weather, change the oil more often.
3.3.1 GENERATOR MAINTENANCE
Generator maintenance consists of keeping the unit clean and dry.
Operate and store the unit in a clean dry environment where it will not
be exposed to excessive dust, dirt, moisture or any corrosive vapors.
Cooling air slots in the generator must not become clogged with snow,
leaves, or any other foreign material.
Check the cleanliness of the generator frequently and clean when
dust, dirt, oil, moisture or other foreign substances are visible on its
exterior surface.
Never insert any object or tool through the air
cooling slots, even if the engine is not running.
NOTE:
DO NOT use a garden hose to clean generator. Water can enter
the engine fuel system and cause problems. In addition, if water
enters the generator through cooling air slots, some water will
be retained in voids and crevices of the rotor and stator winding
insulation. Water and dirt buildup on the generator internal
windings will eventually decrease the insulation resistance of
these windings.
Hot oil may cause burns. Allow engine to cool
before draining oil. Avoid prolonged or repeated
skin exposure with used oil. Thoroughly wash
exposed areas with soap.
NOTE:
Whenever possible, run engine for approximately five (5) minutes
to get the engine oil hot. This will aid in draining the oil.
Use the following instructions to change the oil while the engine
is still warm:
Clean area around oil drain plug.•
Remove oil drain plug from engine and oil fill plug to drain oil •
completely into a suitable container.
When oil has completely drained, install oil drain plug and tighten •
securely.
Fill oil sump with recommended oil. (See “Before Starting the •
Generator” for oil recommendations).
Wipe up any spilled oil.•
Dispose of used oil at a proper collection center.•

3.5 CLEAN SPARK ARRESTOR SCREEN
The engine exhaust muffler has a spark arrestor screen. Inspect and
clean the screen at least once each year (Figure 19). If unit is used
regularly, inspect and clean more often.
NOTE:
If using the generator on any forest-covered, brush-covered
or grass-covered unimproved land, it must equipped with a
spark arrestor. The spark arrestor must be maintained in good
condition by the owner/operator.
Clean and inspect the spark arrestor as follows:
Remove muffler heat shield from muffler, removing four screws.•
Remove spark arrestor from muffler, removing four screws.•
Inspect screen and replace if torn, perforated or otherwise •
damaged. DO NOT USE a defective screen. If screen is not
damaged, clean it with commercial solvent.
Replace the spark arrestor and muffler heat shield.•
Figure 19 - Spark Arrestor
Make sure the piston is at Top Dead Center (TDC) of its •
compression stroke (both valves closed). To get the piston at
TDC, remove the intake screen at the front of the engine to gain
access to the flywheel nut. Use a large socket and socket wrench
to rotate the nut and hence the engine in a clockwise direction
while watching the piston through the spark plug hole. The piston
should move up and down. The piston is at TDC when it is up as
high as it can go.
Insert a 0.002 - 0.004 inch (0.05 - 0.1mm) feeler gauge between •
the rocker arm and valve stem. Correct clearance is when a slight
drag is felt when sliding the gauge back and forth. If the clearance
is either excessively loose or tight the rocker arms will need
adjusting.
To adjust valve clearance:
Loosen the rocker jam nut (Figure 20). Use an 10mm allen wrench •
to turn the pivot ball stud while checking clearance between
the rocker arm and the valve stem with a feeler gauge. Correct
clearance is 0.002-0.004 inch (0.05-0.1 mm).
Figure 20 - Valve Clearance Adjustment
Spark Arrestor
Heat Shield
3.6 ADJUSTING VALVE CLEARANCE
After the first 50 hours of operation, check the valve clearance in
the engine and adjust if necessary.
Important: If feeling uncomfortable about doing this procedure or
the proper tools are not available, please take the generator to the
nearest service center to have the valve clearance adjusted. This is a
very important step to insure longest life for the engine.
To check valve clearance:
Make sure the engine is at room temperature (60° - 80° F).•
Make sure that the spark plug wire is removed from the spark plug •
and out of the way. Remove spark plug.
Remove the four screws attaching the valve cover.•
NOTE:
The rocker arm jam nut must be held in place as the pivot ball
stud is turned.
When valve clearance is correct, hold the pivot ball stud in place with
the allen wrench and tighten the rocker arm jam nut. Tighten the jam
nut to 174 in/lbs. torque. After tightening the jam nut, recheck valve
clearance to make sure it did not change.
Install new valve cover gasket.•
Re-attach the valve cover.•
NOTE:
Start all four screws before tightening or it will not be possible
to get all the screws in place. Make sure the valve cover gasket
is in place. Replace spark plug.
Re-attach the spark plug wire to the spark plug.•

3.7 LONG TERM STORAGE
It is important to prevent gum deposits from forming in essential fuel
system parts such as the carburetor, fuel hose or tank during storage.
Also, experience indicates that alcohol-blended fuels (called gasohol,
ethanol or methanol) can attract moisture, which leads to separation
and formation of acids during storage. Acidic gas can damage the fuel
system of an engine while in storage.
To avoid engine problems, the fuel system should be emptied before
storage of 30 days or longer, as follows:
Remove all gasoline from the fuel tank.•
DANGER
Drain fuel into approved container outdoors,
away from open flame. Be sure engine is cool.
Do not smoke.
Start and run engine until engine stops from lack of fuel.•
While engine is still warm, drain oil from crankcase. Refill with •
recommended grade.
Remove spark plugs and pour about 1/2 ounce (15 ml) of engine •
oil into the cylinders. Cover spark plug hole with rag. Pull the recoil
starter a couple times to lubricate the piston rings and cylinder
bore..
3.8 OTHER STORAGE TIPS
Do not store gasoline from one season to another.•
Replace the gasoline can if it starts to rust. Rust and/or dirt in the •
gasoline will cause problems with the carburetor and fuel system.
If possible, store the unit indoors and cover it to give protection •
from dust and dirt. BE SURE TO EMPTY THE FUEL TANK.
If it is not practical to empty the fuel tank and the unit is to be stored •
for some time, use a commercially available fuel stabilizer added to
the gasoline to increase the life of the gasoline.
Cover the unit with a suitable protective cover that does not retain •
moisture.
DANGER
NEVER cover the generator while engine and
exhaust area are warm.
Avoid spray from spark plug holes when
cranking engine.
Install and tighten spark plugs. Do not connect spark plug wires.•
Clean the generator outer surfaces. Check that cooling air slots •
and openings on generator are open and unobstructed.
Store the unit in a clean, dry place.•
