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.

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
