bodily injury, and/or property damage. Stand clear of generator.
Lift is designed to carry only the weight of the generator. DO
NOT overload lifting bracket. Apply lifting strap or hook through
lift bar hole(s) only. DO NOT lift while generator is running.
Never use the generator or any of its parts as a step. Stepping•
on the unit can stress and break parts, and may result in
dangerous operating conditions from leaking exhaust gases,
fuel leakage, oil leakage, etc.
On electric start models, disconnect the POSITIVE (+) battery•
cable from the engine starter OR the NEGATIVE (-) battery
cable from the battery terminal, whichever is easier, before
transporting the generator.
NOTE:
This generator is equipped with a spark arrestor muffler. The
spark arrestor must be maintained in effective working order
by the owner/ operator. In the State of California, a spark
arrestor is required by law (Section 4442 of the California
Public Resources Code). Other states may have similar laws.
Federal laws apply on federal lands.
EXHAUST & LOCATION HAZARDS
Never operate in an enclosed area or indoors!• NEVER use in
the home, or in partly enclosed areas such as garages, even
if doors and windows are open! ONLY use outdoors and far
from open windows, doors, vents, and in an area that will not
accumulate deadly exhaust.
The engine exhaust fumes contain carbon monoxide, which•
you cannot see or smell. This poisonous gas, if breathed in
sufficient concentrations, can cause unconsciousness or even
death.
Adequate, unobstructed flow of cooling and ventilating air•
is critical to correct generator operation. Do not alter the
installation or permit even partial blockage of ventilation
provisions, as this can seriously affect safe operation of the
generator. The generator MUST be operated outdoors.
This exhaust system must be properly maintained. Do nothing•
that might render the exhaust system unsafe or in noncompliance
with any local codes and/or standards.
Always use a battery operated carbon monoxide alarm indoors,•
installed according to the manufacturers instructions.
If you start to feel sick, dizzy, or weak after the generator has•
been running, move to fresh air IMMEDIATELY. See a doctor, as
you could have carbon monoxide poisoning.
ELECTRICAL HAZARDS
The• generator produces dangerously high voltage when in
operation. Avoid contact with bare wires, terminals, connections,
etc., while the unit is running, even on equipment connected
to the generator. Ensure all appropriate covers, guards and
barriers are in place before operating the generator.
Never handle any kind of electrical cord or device while•
standing in water, while barefoot or while hands or feet are wet.
DANGEROUS ELECTRICAL SHOCK MAY RESULT.
The National Electric Code (NEC) requires the frame and external•
electrically conductive parts of the generator be properly
connected to an approved earth ground. Local electrical codes
may also require proper grounding of the generator. Consult
with a local electrician for grounding requirements in the area.
Use a ground fault circuit interrupter in any damp or highly•
conductive area (such as metal decking or steel work).
Do not use worn, bare, frayed or otherwise damaged electrical•
cord sets with the generator.
Before performing any maintenance on the generator, disconnect•
the engine starting battery (if equipped) to prevent accidental
start up. Disconnect the cable from the battery post indicated
by a NEGATIVE, NEG or (–) first. Reconnect that cable last.
In case of accident caused by electric shock, immediately shut•
down the source of electrical power. If this is not possible,
attempt to free the victim from the live conductor. AVOID
DIRECT CONTACT WITH THE VICTIM. Use a non-conducting
implement, such as a rope or board, to free the victim from the
live conductor. If the victim is unconscious, apply first aid and
get immediate medical help.
FIRE HAZARDS
Gasoline is highly FLAMMABLE and its vapors are EXPLOSIVE• .
Do not permit smoking, open flames, sparks or heat in the
vicinity while handling gasoline.
Never add fuel while unit is running or hot. Allow engine to cool•
completely before adding fuel.
Never fill fuel tank indoors.• Comply with all laws regulating
storage and handling of gasoline.
Do not overfill the fuel tank. Always allow room for fuel•
expansion. If tank is over-filled, fuel can overflow onto a hot
engine and cause FIRE or an EXPLOSION. Never store generator
with fuel in tank where gasoline vapors might reach an open
flame, spark or pilot light (as on a furnace, water heater or
clothes dryer). FIRE or EXPLOSION may result. Allow unit to
cool entirely before storage.
Safety Rules

Wipe up any fuel or oil spills immediately. Ensure that no•
combustible materials are left on or near the generator. Keep the
area surrounding the generator clean and free from debris and
keep a clearance of five (5) feet on all side to allow for proper
ventilation of the generator.
Do not insert objects through unit’s cooling slots.•
Do not• operate the generator if connected electrical devices
overheat, if electrical output is lost, if engine or generator sparks
or if flames or smoke are observed while unit is running.
Keep a fire extinguisher near the generator at all times.•

push-to-reset circuit breaker (Figure 5). Use each socket to power
120 Volt AC, single phase, 60 Hz electrical loads requiring up to a
combined 2400 watts (2.4 kW) or 20 Amps of current. Use only
high quality, well-insulated, 3-wire grounded cord sets rated for
125 Volts at 20 Amps (or greater).
Keep extension cords as short as possible, preferably less than
15 feet long, to prevent voltage drop and possible overheating of
wires.
Figure 5 - 120 Volt AC, 20 Amp, Duplex Receptacle
2.3.2 120/240 VAC, 30 AMP RECEPTACLE

2.3.3 GROUND FAULT SENSING MODULE
This unit is equipped with a ground fault circuit interrupter (GFCI).
This device meets applicable federal, state and local codes. The
ground fault sensing module covers all receptacles.
In the event of a ground fault, the GFCI will trip and quickly stop the
flow of electricity to prevent serious injury.
Definition: The GFCI constantly monitors electricity flowing in a
circuit. If the current flowing through the circuit varies from what
is returning by even a small amount, the GFCI instantly switches
power off by tripping the main circuit breaker on the generator's
control panel.
A GFCI does NOT protect against circuit overloads, short circuits,
or shocks. For example, electric shock can still occur if a person
touches charged electrical wires while standing on a non-
conducting surface, such as a wood floor.
Test the GFCI outlet before each use as follows (Figure 7):
Start the generator.•
Plug a test lamp into duplex receptacle, the lamp should be•
on.
Press the “Test” button on the GFCI to trip the device. The main•
breaker should ‘trip’, this being indicated by the movement of
the actuator handle to the ‘OFF’ position.
This should stop the flow of electricity making the lamp shut•
off. If the main breaker dose not ‘trip’, the GFCI is not working
and the generator should not be used. Contact a local service
dealer.
To restore the flow of electricity, set the main breaker actuator•
handle to the ‘ON’ position. The handles should remain latched
in this position. If it does not, either the GFCI or the main breaker
is failing and should be replaced. Contact a local service
dealer.
This GFCI is protected against overload by a 35A/240V main•
breaker.
Figure 7 - Testing the GFCI
2.3.4 120 VAC, 30 AMP RECEPTACLE
Use a NEMA L5-30 plug with this receptacle (rotate to lock/
unlock). Connect a suitable 3-wire 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).
Use this receptacle to operate 120 Volt AC, 60Hz, single phase
loads requiring up to 7200 watts (7.2kW) of power at 30 Amps.
The outlet is protected by a 30 Amp push-to-reset circuit breaker.
Figure 8 - 120 VAC, 30 Amp Receptacle
2.4 AUTOMATIC IDLE CONTROL
This feature is designed to greatly improve fuel economy. When
this switch is turned “On,” the engine will only run at its normal
fast governed engine speed when electrical load is connected.
When the load is removed, the engine will run at a reduced speed.
With the switch “Off,” the engine runs at the normal fast engine
speed all the time. Always have the switch OFF when starting
and stopping the engine (Figure 12).
2.5 VOLTAGE SELECTOR SWITCH (XP6500E
ONLY)
The voltage selector switch, when in the "120/240V" position,
divides the available power into 120V and 240V available through
all appropriate receptacles. When in the "120V only" position, all
power is provided at 120V and equally balances the alternator.
2.6 HOW TO USE THE GENERATOR
If there are any problems operating the generator, please call the
generator helpline at 1-888-436-3722.
nNever operate in an enclosed area or indoors!
NEVER use in the home, or in partly enclosed
areas such as garages, even if doors and
windows are open! ONLY use outdoors and far
from open windows, doors, vents, and in an
area that will not accumulate deadly exhaust.
nThe engine exhaust fumes contain carbon
monoxide, which you cannot see or smell.
This poisonous gas, if breathed in sufficient
concentrations, can cause unconsciousness or
even death.
Operation

8
nAdequate, unobstructed flow of cooling and
ventilating air is critical to correct generator
operation. Do not alter the installation or permit
even partial blockage of ventilation provisions,
as this can seriously affect safe operation
of the generator. The generator MUST be
operated outdoors.
nThis exhaust system must be properly
maintained. Do nothing that might render the
exhaust system unsafe or in noncompliance
with any local codes and/or standards.
nAlways use a battery operated carbon
monoxide alarm indoors, installed according to
the manufacturers instructions.
2.6.1 SYSTEM GROUND
The generator has a system ground that connects the generator
frame components to the ground terminals on the AC output
receptacles. The system ground is bonded to the AC neutral wire
in the generator control panel via a jumper wire.
Special Requirements
There may be Federal or State Occupational Safety and Health
Administration (OSHA) regulations, local codes, or ordinances that
apply to the intended use of the generator.
Please consult a qualified electrician, electrical inspector, or the
local agency having jurisdiction:
In some areas, generators are required to be registered with•
local utility companies.
If the generator is used at a construction site, there may be•
additional regulations which must be observed.
Connecting to a Building’s Electrical System
Connections for standby power to a building’s electrical system
must be made by a qualified electrician. The connection must
isolate the generator power from utility power or other alternative
power sources and must comply with all related laws and codes.
2.6.2 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.
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.
2.6.3 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".
2.7 OVERLOAD PREVENTION
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.
Operation

9
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.

2.9 BEFORE STARTING THE GENERATOR
Prior to operating the generator, engine oil and gasoline will need
to be added, as follows:
2.9.1 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•
10W-30
10W-30
SAE 30
SA E 3 0
Synthetic 5W-30
Synthetic 5W-30
n
Any attempt to crank or start the engine
before it has been properly serviced with the
recommended oil may result in an engine
failure.
Place generator on a level surface.•
Clean area around oil fill and remove oil fill cap.•
Slowly fill engine with oil through the oil fill opening until it•
reaches the full mark. Stop filling occasionally to check oil level.
The engine is full when the oil level reaches the bottom threads
of the mating oil fill cap.
Install the oil fill cap and finger tighten securely.•
Check engine oil level before starting each time thereafter.•
Operation

10
2.9.2 ADDING GASOLINE
Use care when fueling the generator. Only fill the fuel tank when the
generator has cooled entirely. Use fresh unleaded gasoline with a
minimum Research Octane Number (RON) of 87.
NOTE:
Do not use any gasoline containing more than 10% Ethanol.
NEVER fill the fuel tank with E85 or a mixture of oil and gasoline
designated for two-cycle engines.
n
Do not light a cigarette or smoke when filling
the fuel tank.

Gasoline is highly FLAMMABLE and its vapors
are EXPLOSIVE. Do not permit smoking, open
flames, sparks or heat in the vicinity while
handling gasoline.

Never fill fuel tank indoors. Never fill fuel tank
when engine is running or hot. Avoid spilling
gasoline on a hot engine. Allow engine to cool
entirely before filling fuel tank.

Do not overfill the fuel tank. Always allow room
for fuel expansion. If the fuel tank is overfilled,
fuel can overflow onto a hot engine and cause
a fire or an explosion. Wipe up any fuel spills
immediately.
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. Do not fill•
above inner lip. Be careful not to overfill (Figure 10).
Install fuel cap and wipe up any spilled gasoline.•
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.

2.13 LOW OIL LEVEL SHUTDOWN SYSTEM
The engine is equipped with a low oil level sensor that shuts down
the engine automatically when the oil level drops below a specified
level. If the engine shuts down by itself and the fuel tank has
enough gasoline, check engine oil level.
If the system senses a low oil level during operation, the engine
shuts down. The engine will not run until the oil has been refilled
to the proper level.
2.14 CHARGING THE BATTERY

Storage batteries give off explosive hydrogen
gas while recharging. An explosive mixture will
remain around the battery for a long time after
it has been charged. The slightest spark can
ignite the hydrogen and cause an explosion.
Such an explosion can shatter the battery and
cause blindness or other serious injury.
n
Do not permit smoking, open flame, sparks
or any other source of heat around a battery.
Wear protective goggles, rubber apron and
rubber gloves when working around a battery.
Battery electrolyte fluid is an extremely
corrosive sulfuric acid solution that can cause
severe burns. If spill occurs flush area with
clear water immediately.
NOTE:
The battery shipped with the generator has been fully charged.
A battery may lose some of its charge when not in use for
prolonged periods of time. If the battery is unable to crank the
engine, plug in the 12V charger included in the accessory box
(see section "Charging the Battery"). RUNNING THE GENERATOR
WILL CHARGE THE BATTERY.
Use battery charger plug to keep the battery charged and ready for
use. Battery charging should be done in a dry location.
1. Plug charger into “Battery Charger Input” jack, located on the
control panel. Plug wall receptacle end of the battery charger
into a 120 Volt AC wall outlet (Figure 13).

Maintenance
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.
n
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.
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


3.3.10 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.•
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 18). 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 18 - Valve Clearance Adjustment
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.•
3.4 GENERAL
The generator should be started at least once every seven days and
be allowed to run at least 30 minutes. If this cannot be done and
the unit must be stored for more than 30 days, use the following
information as a guide to prepare it for storage.

NEVER store engine with fuel in tank indoors
or in enclosed, poorly ventilated areas where
fumes may reach an open flame, spark or pilot
light as on a furnace, water heater, clothes dryer
or other gas appliance.
n
Allow unit to cool entirely before storage.
3.5 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.
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.
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.•

Drain fuel into approved container outdoors,
away from open flame. Be sure engine is cool.
Do not smoke in the vicinity or light a cigarette.
Maintenance

16
Start and run engine until engine stops from lack of fuel.•
After the engine cools down, drain oil from crankcase. Refill•
with recommended grade.
Remove spark plug and pour about 1/2 ounce (15 ml) of engine•
oil into the cylinder. Cover spark plug hole with rag. Pull the
recoil starter a couple times to lubricate the piston rings and
cylinder bore.
n
Avoid spray from spark plug hole when
cranking engine.
Install and tighten spark plug. Do not connect spark plug wire.•
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.•
Do not store gasoline from one season to another.•
Cover the unit with a suitable protective cover that does not•
retain moisture.
n
NEVER cover the generator while engine and
exhaust area are warm. Allow unit to cool
entirely.
