Add Gasoline

DANGER!

NEVER fill fuel tank indoors.

NEVER fill fuel tank when engine is running or

hot. DO NOT light a cigarette or smoke when

filling the fuel tank.

DANGER! 

Do not overfill the fuel tank. Always

leave room for expansion.

• Use 

regular UNLEADED gasoline

in the generator.

DO NOT use premium gasoline. DO NOT mix oil

with gasoline. DO NOT overfill the gas tank.

• Clean area around fuel fill cap; remove cap.
• Fill fuel tank with clean, fresh, unleaded gasoline. Be

careful not to overfill. Allow 1/2" of tank space for fuel

expansion (Figure 2).

• Install fuel cap and wipe up any spilled gasoline.

IMPORTANT:

It is important to prevent gum deposits

from forming in essential fuel system parts such as the

carburetor, fuel filter, 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. See “Storage” on

page 12. Never use engine or carburetor cleaner

products in the fuel tank or permanent damage may

occur.

OPERATING THE

GENERATOR

CAUTION!

Never start or stop the unit with

electrical loads connected to the receptacles.

Starting the Engine

• Disconnect 

all

electrical loads from the generator.

• Make sure the Idle Control Switch is turned 

OFF.

• Open the fuel shut–off valve.
• Set the Ignition Switch to the 

On (–)

position.

• Pull choke control out to close choke.

NOTE

: If engine is warm, you may not need as much

choking.

NOTE

: Make sure the idle control switch is “Off” before

starting the engine.
• Pull slowly on recoil handle until you feel some

resistance. Then pull rapidly to start engine. Return

recoil slowly, do not let it “

snap back

” 

Applying Electrical Loads

• Let engine stabilize and warm up for about two

minutes after starting.

• Plug in and turn on the desired 120 or 240 Volt AC,

single phase, 60 Hertz electrical loads. 

DO NOT

OVERLOAD THE GENERATOR.

Add up the rated

watts (or Amps) of all loads to be connected at one

time. This total should not be greater than the rated

wattage/amperage capacity of the generator. See

page 11, “Don’t Overload the Generator” for details.

Stopping the Engine

• Disconnect 

all

electrical loads.

• Turn 

OFF

idle control.

• Run engine at no–load for a few minutes. 
• Set the Ignition Switch to the 

Stop (o)

position.

• Close the fuel shut–off valve.
