Important information

This machine has been provided with an EPA-certified engine.

Additional information can be found in the engine

manufacturer‘s notes.

Engine exhaust, some of its constitvents, and certain vehicle

components contain or emit chemicals known to the State of

California to cause cancer and birth defects or other reproduc-

tive harm.

WARNING

Caution

This engine is an EPA engine.

Adjusting the engine speed will interfere with EPA certification and

the emissions.

Only authorized personnel can make adjustments to this engine.

Please contact you nearest engine dealer or your Wacker Dealer for more

information.

T00953GB.fm 5

Emission Control System Information

Source of Emissions

The combustion process produces carbon monoxide, oxides of

nitrogen, and hydrocarbons. Control of hydrocarbons and oxides of

nitrogen is very important because, under certain conditions, they

react to form photochemical smog when subjected to sunlight. Carbon

monoxide does not react in the same way, but it is toxic.

Wacker utilizes lean carburetor settings and other systems to reduce

the emissions of carbon monoxide, oxides of nitrogen, and

hydrocarbons.

The U.S. and California Clean Air Acts

EPA and California regulations require all manufacturers to furnish

written instructions describing the operation and maintenance of

emission control systems.

The following instructions and procedures must be followed in order to

keep the emissions from your Wacker engine within the emissions

standards.

Tampering and Altering

Tampering with or altering the emission control system may increase

emissions beyond the legal limit. Among those acts that constitute

tampering are:

•Removal or alteration of any part of the intake, fuel, or exhaust

systems.

•Altering or defeating the speed-adjusting mechanism to cause the

engine to operate outside its design parameters.

Problems That May Affect Emissions

If you are aware of any of the following symptoms, have your engine

inspected and repaired by your servicing dealer.

•Hard starting or stalling after starting.

•Rough idle.

•Misfiring or backfiring under load.

•Afterburning (backfiring).

•Black exhaust smoke or high fuel consumption.

T00953GB.fm 6

Replacement Parts

The emission control systems on your Wacker engine were designed,

built, and certified to conform with EPA and California emissions

regulations. We recommend the use of genuine Wacker parts

whenever you have maintenance done. These original-design

replacement parts are manufactured to the same standards as the

original parts, so you can be confident of their performance. The use

of replacement parts that are not of the original design and quality may

impair the effectiveness of your emission control system.

A manufacturer of an aftermarket part assumes the responsibility that

the part will not adversely affect emission performance. The

manufacturer or rebuilder of the part must certify that use of the part

will not result in a failure of the engine to comply with emission

regulations.

Maintenance

Follow the maintenance schedule. Remember that this schedule is

based on the assumption that your machine will be used for its

designed purpose. Sustained high-load or high-temperature operation,

or use in unusually wet or dusty conditions, will require more frequent

service.

OXYGENATED FUELS

Some conventional gasolines are being blended with alcohol or an

ether compound. These gasolines are collectively referred to as

oxygenated fuels. To meet clean air standards, some areas of the

United States and Canada use oxygenated fuels to help reduce

emissions.

If you use an oxygenated fuel, be sure it is unleaded and meets the

minimum octane rating requirement.

Before using an oxygenated fuel, try to confirm the fuel’s contents.

Some States / Provinces require this information to be posted on the

pump.

The following are EPA-approved percentages of oxygenates:

ETHANOL - (ethyl or grain alcohol) 10% by volume. You may use

gasoline containing up to 10% ethanol by volume. Gasoline containing

ethanol may be marketed under the name “Gasohol”.

MTBE - (methyl tertiary butyl ether) 15% by volume. You may use

gasoline containing up to 15% MTBE by volume.

T00953GB.fm 7

METHANOL - (methyl or wood alcohol) 5% by volume. You may use

gasoline containing up to 5% methanol by volume, as long as it

contains cosolvents and corrosion inhibitors to protect the fuel system.

Gasoline containing more than 5% methanol by volume may cause

starting and/or performance problems. It may also damage metal,

rubber, and plastic parts of your fuel system.

If you notice any undesirable operating symptoms, try another service

station, or switch to another brand of gasoline.

Fuel system damage or performance problems resulting from the use

of an oxygenated fuel containing more than the percentages of

oxygenates mentioned above are not covered under warranty.

Emission Control System Warranty

Your new Wacker engine complies with the U.S. EPA emissions

regulations. Wacker provides the same emission warranty coverage

for engines sold in all 50 states.

YOUR WARRANTY RIGHTS AND OBLIGATIONS

All States

Wacker must warrant the emission control system on your engine for

the period of time listed below provided there has been no abuse,

neglect or improper maintenance of your engine. Where a warrantable

condition exists, Wacker will repair your engine at no cost to you

including diagnosis, parts and labor.

Your emission control system may include such parts as the

carburetor, the ignition system and the catalytic converter.

Also included may be hoses, connectors and other emission-related

assemblies.

MANUFACTURER’S WARRANTY COVERAGE:

The 1998 and later engines are warranted for two years. If any

emission-related part on your engine is defective, the part will be

repaired or replaced by Wacker.

T00953GB.fm 8

OWNER’S WARRANTY RESPONSIBILITY:

As the engine owner, you are responsible for the performance of the

required maintenance listed in your owner’s manual. Wacker

recommends that you retain all receipts covering maintenance on your

engine, but Wacker cannot deny warranty coverage solely for the lack

of receipts or for your failure to ensure the performance of all

scheduled maintenance.

As the engine owner, you should be aware that Wacker may deny you

warranty coverage if your engine or a part has failed due to abuse,

neglect, improper maintenance or unapproved modifications.

You are responsible for presenting your engine to a Wacker dealer as

soon as a problem exists. The warranty repairs should be completed

in a reasonable amount of time, not to exceed 30 days.

If you have any questions regarding your warranty rights and

responsibilities, you should contact your local Wacker dealer.

WARRANTY COVERAGE:

Wacker engines sold after January 1, 1998, are covered by this

Emission Control System Warranty for a period of two years from the

date of delivery to the original retail purchaser. This warranty is

transferable to each subsequent purchaser for the duration of the

warranty period.

Warranty repairs will be made without charge for diagnosis, parts or

labor. All defective parts replaced under this warranty become property

of Wacker. A list of warranted parts is located on the next page. Normal

maintenance items, such as spark plugs and filters, that are on the

warranted parts list are warranted up to the required replacement

interval only.

Wacker is also liable for damages to other engine components caused

by a failure of any warranted parts during the warranty period.

Only Wacker approved replacement parts may be used in the

performance of any warranty repairs and must be provided without

charge to the owner. The use of replacement parts not equivalent to

the original parts may impair the effectiveness of your engine emission

control system. If such a replacement part is used in the repair or

maintenance of your engine, and an authorized Wacker dealer

determines it is defective or causes a failure of a warranted part, your

claim for repair of your engine may be denied. If the part in question is

not related to the reason your engine requires repair, your claim will not

be denied.

T00953GB.fm 9

TO OBTAIN WARRANTY SERVICE:

You must take your Wacker product along with proof of original

purchase date, at your expense, to any Wacker authorized dealer

during their normal business hours. Claims for repair or adjustment

found to be caused solely by defects in material or workmanship will

not be denied because the engine was not properly maintained and

used.

EXCLUSIONS:

FAILURES OTHER THAN THOSE RESULTING FROM DEFECTS IN

MATERIAL OR WORKMANSHIP ARE NOT COVERED BY THIS

WARRANTY. THIS WARRANTY DOES NOT EXTEND TO

EMISSION CONTROL SYSTEMS OR PARTS WHICH ARE
