Dayton® Generator

•To minimize gum deposits in your fuel

Esystem and to insure easy starting,

Ndo not use gasoline left over from

Gthe previous season.

L•Do not add oil to the gasoline.

I	Fuel Type
S
	•For best results use only clean, fresh,
H
	unleaded gasoline with a pump
	sticker octane rating of 87 or higher.
	•Unleaded gasoline is recommended as
	it leaves less combustion chamber
	deposits.
	Gasoline/Alcohol Blends:
	Gasohol (up to 10% ethyl alcohol,
	90% unleaded gasoline by volume) is
	approved, as a fuel. Other gasoline/
	alcohol blends are not approved.
	Gasoline/Ether Blends:
	Methyl Tertiary Butyl Ether (MTBE)
	and unleaded gasoline blends (up to a
	maximum of 15% MTBE by volume) are
	approved as a fuel. Other gasoline/ether
	blends are not approved.
	BATTERY INSTALLATION
		SHOULD ONLY
		BE DONE BY AN
	AUTHORIZED DEALER.
	HIGH ALTITUDE
	At high altitude, the standard carburetor
	air/fuel mixture will be too rich.
	Performance will decrease, and fuel
	consumption will increase. A very rich
	mixture will also foul the spark plug and
	cause hard starting. Operation at an
	altitude that differs from that at which
	this engine was certified, for extended
	periods of time, may increase emissions.
	High altitude performance can be
	improved by specific modifications to the
	carburetor. If you always operate your
	generator at altitudes above 5,000 feet
	(1,500 meters), have your dealer perform
	this carburetor modification. This engine,

when operated at high altitude with the carburetor modifications for high altitude use, will meet each emission standard throughout its useful life.Even with carburetor modification, engine horsepower will decrease about 3.5% for each 1,000-foot (300-meter) increase in altitude. The effect of altitude on horsepower will be greater than this if no carburetor modification is made.

NOTE:When the carburetor has been modified for high altitude operation, the air/fuel mixture will be too lean for low altitude use. Operation at altitudes below 5,000 feet (1,500 meters) with a modified carburetor may cause

the engine to overheat and result in serious engine damage. For use at low altitudes, have your servicing dealer return the carburetor to original factory specifications.

Operation

Recoil Start

NOTE: Read Operator’s Manual carefully before operating this unit. Always make sure the unit is level and properly grounded. Check engine oil before starting.

1.Open fuel valve on unit or engine. (See Below)

2.Turn the idle control switch to the OFF position.

3.Move choke lever to full choke. If re- starting a warm engine, the choke should be left in the off position.

(See Below)

4.Turn the engine ignition switch to the ON position.

5.Pull recoil to start engine.

6.Once engine has started, slowly move choke lever to no choke.

NOTE: When engine fails to start after several attempts, repeat the starting procedures mentioned above with the choke lever in the off position.

7.Allow the unit to run for two (2) minute warm-up.

8.Make sure the generator is grounded. See Preparing the Generator; Grounding Instructions.

9.Turn main breaker to ON position (GEN-6000 units only).

10.Test the GFCI receptacle(s) on the unit. Push the test button. The reset button should pop out and there should be no power at the receptacle. Apply a test load or lamp to each receptacle to verify. IF THE RESET BUTTON DOES NOT POP OUT, DO NOT USE THE RECEPTACLES(S). SEE DEALER FOR SERVICE IMMEDIATELY.
