1.
SAFETY
The generators are designed to give safe and dependable service ifoperated
according
tO
instructions. Read and understand this owner's manual before operating
your generator.
You
can help prevent accidents by being familiar with your generator's
controls, and by observing safe operating procedures.
Operator Responsibility
• Know howto stop the generatorquickly
in
case
of
emergency.
• Understand the use
of
all generatorcontrols,output receptacles.Andconnections.
• Be sure that anyone who operates the generator receives proper instruction. Do
not let children operate the generatorwithout parental supervision. Keep children
and pets away from the area
of
operation.
• Place the generatoron a firm, level surface and avoid loose sand
or
snow.
If
the
generator is tilted
or
overturned, fuel spillage may result. Also. If the generator
is
overturned
or
sinks into a soft
surface,
sand,dirt,
or
water may enterthe generator.
Carbon Monoxide Hazards
• Exhaust Contains poisonous carbon monoxide. a colorless and odorless gas
Breathing exhaustcan cause loss
of
consciousness and maylead to death.
• Ifyou run the generator
in
an area that is confined orever partially enclosed. The air
you breathe could contain a dangerous amount
of
exhaust gas.
To
keep exhaust
gas from building up , provide adequate ventilation.
Electric Shock Hazards
• The generator produces enough electric power to cause a serious shock
or
electrocution ifmisused.
• Using a generatorelectrical appliance
in
wetconditions, such as rain
or
snow, or
near a pool
or
sprinkler system,
or
when your hands are wet: could result
in
electrocution. Keep the generator dry.
• If the generator is stored outdoors, unprotected from the weather, check all
electrical components on the control panel. before each use. Moisture or ice can cause
a malfunction
or
short circuit
in
electrical components which could result
in
electrocution.
• Do not connect to a building's electrical system unless an isolation switch has been
installed by a qualified electrician.
2

Fire
and
Burn
Hazards
• The exhaust system gets hot enough to ignite some materials.
—Keep the generatorat least 1 meter (3 feet) away from buildings and other
equipment during operation
-Do not enclose the generator
in
anystructure.
—Keep flammable materials away from the generator.
• The mufflerbecomes very hot during operation and remains hotfora while after
stopping the engine.Be careful not to touch the mufflerwhile it is hot. Let the engine
cool before storing the generatorindoors-.
• Gasoline is extremely flammable and is explosive under certain conditions. Do
not Smoke or allow flames or sparks where the generator
is
refueled or where
gasoline
is
stored. Refuel
in
a well-ventilated area with the engine stopped.
• Fuel vapors extremelyflammable and may ignite afterthe engine has started. Make
sure that any spilled fuel ha& been wiped up before starting the generator.

not
use
the starter
for
more than 5 seconds
at
a time.
If
the engine fails
to
start,
release the
switch
and
wait
10 seconds before operating the starter again.
2) Recoil Starter
To start the engine, pull the starter grip lightly until resistance is felt, then pull briskly.
| NOTlCE | Do not a||ow the

Return
it
gently to prevent damage to the starter.
3) Fuel Valve
The fuel valve
is
located between the fuel tank and carburetor. When the valve lever
is
in
the
ON
position,fuel
is
allowed
to
flow from the fuel tank to the carburetor.
Be
sure to
Return the lever to OFF after stopping the engine.

each
receptacle. Before using the ground terminal, consult a qualified electrician, electrical
inspector
or
local agency having jurisdiction for local codes orordinances that apply to
the intended use
of
the generator.
7) Oil
Alert
System
The oil alert system is designed to prevent engine damage caused by an insufficient
amount
of
oil
in
the crankcase. Before the oil level
in
the crankcase can fall below a
safe limitthe oil alert system will automatically shut down the engine (the engine
switch will remain
in

ion)
.
The oil alert system shuts down the engine and
the engine will not start. Ifthis occurs,first check engine oil.
4. GENERATOR USE
1) Connections to a Building's Electrical System
Connections for standby powerto a building's electrical system must be made by a
qualified electrician.the connection must isolate the generator powerfrom utility power
and mustcom ply with all applicable laws and electrical codes.

1)
AC
Applications
Before connecting an appliance
or
powerto the generator:
• Make sure that it
is
in
good working order. Faulty appliances
or
powercords can
create a potential for electrical shock.
• Ifan appliance begins to operate abnormally, becomes sluggish or stops suddenly.
turn it offimmediately. Disconnect the appliance, and determine whetherthe problem
is
the appliance,
or
ifthe rated load capacity
of
the generator has been exceeded.
• Make sure thatthe electrical, rating
of
the tool
or
appliance does not exceed that
of
the generator. Neverexceed the maximum power rating
of
the generator. Power
levels between rated and maximum may be used for no more than 30 minutes.

High
Altitude
Operation
At high altitude,the standard carburetor air-fuel mixture will be excessively rich.
Performance will decrease, and fuel -consumption will increase.
High altitude performance can be improved by installing a smaller diameter main fuel
jet
in
the carburetor and readjusting the pilot screw, Ifyou always operate the engine
atattitudes higherthan 5000 feel (1500 meters) above sea level, have an authorized
generatordealer perform this carburetor modification.
Even with suitable
carburetor
」
etting,
engine horsepower will decrease approximately
3.5% for each 1000foot (300 meter) increase
in
altitude.The effect
of
altitude on
horsepowerwill be greaterthan this ifno carburetor modification
is
made.

Use gasoline with a pump octane rating
of
86
or
higher.
We recommend unleaded gasoline because it produces fewer engine and spark plug
deposits and extends exhaust system life.
Never use stale
or
contaminated gasoline
or
oil/gasoline mixture.Avoid getting dirt
or
water
in
the fuel tank.
Occasionally you may hear light'spark knock"
or
"pinging" (metallic rapping noise)
while operating underheavy loads. This is no cause for concern
ifspark knock or pinging occurs at a steady engine speed. under normal load, change
brands
of
gasoline. Ifspark knock
or
pinging persists, see an authorized generator
dealer.

Oxygenated
Fuels
Some gasoline are blended with alcohol
or
an ethercompound to increase the octane
These gasoline are collectively referred to as oxygenated fuels. some areas
of
the
United States use oxygenated fuels to help meet clean air standards.
If you use an oxygenated fuel, be sure its pump octane rating is 86 or higher.
Ethanol
(ethyl
or
grain
alcohol)
Gasoline containing more than 10% ethanol by volume maycause starting
or
performance problems. Gasoline containing ethanol may be marketed under: the name
"Gasohol".
Methanol
(methyl
or
wood
alcohol)
Gasoline containing methanol must contain cosolvents and corrosion inhibitors to
protect the fuel system. Gasoline containing more than
5¾
methanol by volume may
cause starting and/or performance problems and maydamage metal. rubber and
plastic parts
of
yourfuel system.
14

MTBE (methyl
tertiary
butyl
ether)
You
MAY use gasoline containing up to 15% MTBE by Volume.
Before using
an
oxygenated fuel,try to
confi
「
mthe fuel's contents. Some states
(provinces
in
Canada) require this information lo he posted
on
the pump. Ifyou notice
any undesirable operating symptoms, switch to a conventional unleaded gasoline. Fuel
system damage or performance problems resulting from the USE Of
an
oxygenated fuel
are not ours responsibility and are not covered underwarranty.
