Fire or explosion can cause severe burns or death.

Gasoline and gasoline vapors:

– Gasoline is highly ﬂammable and explosive.

– Gasoline can cause a ﬁre or explosion if ignited.

– Gasoline is a liquid fuel but it’s vapors can ignite.

– Gasoline is a skin irritant and needs to be cleaned up

immediately if spilled on skin or clothes.

– Gasoline has a distinctive odor, this will help detect potential

leaks quickly.

– Gasoline expands or contracts with ambient temperatures.

Never ﬁll the gasoline tank to full capacity, as gasoline needs room to expand when temperatures rise.

NOTICE

The generator engine works well with 10% or less ethanol blend gasoline. When using ethanol-gasoline blends there are some issues worth noting:

A ground terminal connected to the frame of the generator has been provided (see Controls and Features for terminal location). For remote grounding, connect of a length of heavy gauge (12 AWG minimum) copper wire between the generator ground terminal and a copper rod driven into the ground. We strongly recommend that you consult with a qualiﬁed electrician to ensure compliance with local electrical codes.

Neutral Floating*

– Neutral circuit IS NOT electrically connected to the frame/

ground of the generator.

– The generator (stator winding) is isolated from the frame and

from the AC receptacle ground pin.

– Electrical devices that require a grounded receptacle pin

connection will not function if the receptacle ground pin is not functional.

Neutral Bonded to Frame*

– Neutral circuit IS electrically connected to the frame/ground of

the generator.

– The generator system ground connects lower frame cross-

member below the alternator. The system ground is connected to the AC neutral wire.

* See your model’s control panel for speciﬁed type of grounding.

OPERATION

– Ethanol-gasoline blends can absorb more water than

gasoline alone.

– These blends can eventually separate, leaving water or

a watery goo in the tank, fuel valve and carburetor. The compromised gasoline can be drawn into the carburetor and cause damage to the engine and/or potential hazards.

– If a fuel stabilizer is used, conﬁrm that it is formulated to

work with ethanol-gasoline blends.

– Any damages or hazards caused by using improper

gasoline, improperly stored gasoline, and/or improperly formulated stabilizers, are not covered by manufacturer’s warranty.

It is advisable to always shut off the gasoline supply and run the engine to starvation after each use. See Storage instructions for extended non-use.

Grounding

Your generator must be properly connected to an appropriate ground to help prevent electric shock.

 WARNING



NOTICE

If the engine will not be used for a period of two (2) weeks or longer, please see the Storage section for proper engine and fuel storage.

Operation at High Altitude

The density of air at high altitudes is lower than at sea level. Engine power is reduced as the air mass and air-fuel ratio decrease. Engine power and generator output will be reduced approximately 3½% for every 1000 ft. of elevation above sea level. At high altitudes increased exhaust emissions can also result due to the increased enrichment of the air fuel ratio. Other high altitude issues can include hard starting, increased fuel consumption and spark plug fouling.

 WARNING

Operation using the alternative main jet at elevations lower than the recommended minimum altitude can damage the engine. For operation at lower elevations, the originally supplied standard main jet must be used. Operating the engine with the wrong engine conﬁguration at a given altitude may increase its emissions and decrease fuel efﬁciency and performance.

Moving the Generator

– NEVER lift or carry the generator using the folding handle.

– ALWAYS place the generator on its wheels in the upright

position.

– ALWAYS turn the generator off and ensure the fuel valve is

closed.

CHAMPION POWER EQUIPMENT, INC. (CPE),

THE UNITED STATES ENVIRONMENTAL PROTECTION AGENCY (U.S. EPA)

AND THE CALIFORNIA AIR RESOURCES BOARD (CARB) EMISSION CONTROL SYSTEM WARRANTY

Your Champion Power Equipment (CPE) engine complies with both the U.S. EPA and state of California Air Resources Board (CARB) emissions regulations.

YOUR WARRANTY RIGHTS AND OBLIGATIONS:

The US EPA, California Air Resources Board, and CPE are pleased to explain the Federal and California Emission Control Systems warranty on your 2022 small off-road engine (SORE) and equipment. In the United States and California, new small off-road engines (SORE) and new

equipment that use small off-road engines (SORE) must be designed, built and equipped to meet the State’s stringent anti-smog standards.

CPE must warrant the emission control system on your small off-road engine (SORE) and equipment for the period of time listed below, provided there has been no abuse, neglect or improper maintenance of your small off-road engine (SORE) and equipment leading to the failure of the emission control system.

Your emission control system may include parts such as the carburetor, fuel-injection system, the ignition system, catalytic converter, fuel tanks, fuel lines (for liquid fuel and fuel vapors), fuel caps, valves, canisters, ﬁlters, clamps, connectors, and other associated components. Also included may be hoses, belts, and other emission related assemblies. Where a warrantable condition exits, CPE will repair your small off-road engine (SORE) and equipment at no cost to you including diagnosis, parts and labor.

MANUFACTURER’S WARRANTY COVERAGE:

This Emissions Control System is warranted for two years. If any emissions-related part on your small off-road engine (SORE) and equipment is defective, the part will be repaired or replaced by CPE.

OWNER WARRANTY RESPONSIBILITIES:

As the small off-road engine (SORE) and equipment owner, you are responsible for the performance of the required maintenance listed in your Owner’s Manual. CPE recommends that you retain all your receipts covering maintenance on your small off-road engine (SORE) and equipment, but CPE cannot deny warranty coverage solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance.

As the small off-road engine (SORE) and equipment owner, you should be aware that CPE may deny you warranty coverage if your small off-road engine (SORE) and equipment or a part has failed due to abuse, neglect, improper maintenance or unapproved modiﬁcations.

You are responsible for presenting your small off-road engine (SORE) and equipment to an Authorized CPE service outlet or alternate service outlet as described in (3)(f.) below, CPE dealer or CPE, Santa Fe Springs, Ca. as soon as a problem exists. The warranty repairs shall be completed in a reasonable amount of time, not to exceed 30 days.

The following are speciﬁc provisions relative to your Emission Control System (ECS) Warranty Coverage.

1. APPLICABILITY: This warranty shall apply to 1995 and later model year California small off-road engines (SORE) (for other states,

1997 and later model year engines). The ECS Warranty Period shall begin on the date the new engine or equipment is delivered to its original, end-use purchaser, and shall continue for 24 consecutive months thereafter.

2. GENERAL EMISSIONS WARRANTY COVERAGE CPE warrants to the original, end-use purchaser of the new engine or equipment and to each subsequent purchaser that each of its small off-road engines (SORE) is:

2a. Designed, built and equipped so as to conform to U.S. EPA emissions standards for spark- ignited engines at or below 19 kilowatts

and all applicable regulations adopted by the California Air Resources Board; and

2b. Free from defects in materials and workmanship that cause the failure of a warranted part to be identical in all material respects

to the part as described in the engine manufacturer’s application for certiﬁcation for a period of two years.

3. THE WARRANTY ON EMISSION-RELATED PARTS WILL BE INTERPRETED AS FOLLOWS:

3a. Any warranted part that is not scheduled for replacement as required maintenance in the Owner’s Manual shall be warranted for

the ECS Warranty Period. If any such part fails during the ECS Warranty Period, it shall be repaired or replaced by CPE according to Subsection “d” below. Any such part repaired or replaced under the ECS Warranty shall be warranted for a time not less than the remainder of the ECS Warranty Period.

3b. Any warranted, emissions-related part which is scheduled only for regular inspection as speciﬁed in the Owner’s Manual shall be

warranted for the ECS Warranty Period. A statement in such written instructions to the effect of “repair or replace as necessary” shall advise owners of the warranty coverage for emission related parts. Replacement within the warranty period is covered by the warranty and shall not reduce the ECS Warranty Period. Any such part repaired or replaced under the ECS Warranty shall be warranted for a time not less than the remainder of the ECS Warranty Period.

3c. Any warranted, emissions-related part which is scheduled for replacement as required maintenance in the Owner’s Manual shall

be warranted for the period of time prior to the ﬁrst scheduled replacement point for that part. If the part fails prior to the ﬁrst scheduled replacement, the part shall be repaired or replaced by CPE according to Subsection “d” below. Any such emissionsrelated part repaired or replaced under the ECS Warranty, shall be warranted for a time not less than the remainder of the ECS Warranty Period prior to the ﬁrst scheduled replacement point for such emissions-related part.

3d. Repair or replacement of any warranted, emissions-related part under this ECS Warranty shall be performed at no charge to the

owner at a CPE Authorized Service Outlet.

3e. The owner shall not be charged for diagnostic labor which leads to the determination that a part covered by the ECS Warranty is in

fact defective, provided that such diagnostic work is performed at a CPE Authorized Service Outlet.

3f. CPE shall pay for covered emissions warranty repairs at non-authorized service outlets under the following circumstances:

i. The service is required in a population center with a population over 100,000 according to U.S. Census 2000 without a CPE

Authorized Service Outlet AND

ii. The service is required more than 100 miles from a CPE Authorized Service Outlet. The 100 mile limitation does not apply in the

following states: Alaska, Arizona, Colorado, Hawaii, Idaho, Montana, Nebraska, Nevada, New Mexico, Oregon, Texas, Utah and Wyoming.

3g. CPE shall be liable for damages to other original engine components or approved modiﬁcations proximately caused by a failure

under warranty of an emission-related part covered by the ECS Warranty.

3h. Throughout the ECS Warranty Period, CPE must maintain a supply of warranted emission-related parts sufﬁcient to meet the

expected demand for such emission-related parts and must obtain additional parts if that supply is exhausted.

3i. Any CPE Authorized and approved emission-related replacement part that do not increase the exhaust or evaporative emissions of

the engine or emissions control system may be used in the performance of any ECS Warranty maintenance or repair and will be provided without charge to the owner. Such use shall not reduce CPE’s warranty obligation.

3j. Unapproved add-on or modiﬁed parts may not be used to modify or repair a CPE engine. Such use voids this ECS Warranty and

shall be sufﬁcient grounds for disallowing an ECS Warranty claim. CPE shall not be liable hereunder for failures of any warranted parts of a CPE engine caused by the use of such an unapproved add-on or modiﬁed part.
