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 sun-
light. Carbon monoxide does not react in the same way, but it is toxic.
We 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 the 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:
oRemoval or alteration of any part of the intake, fuel or exhaust systems.
oAltering 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 re-
paired by your servicing dealer:
oHard starting or stalling after starting.
oRough idle.
oMisfiring or backfiring under load.
oAfterburning(backfiring).
oBlack exhaust smoke or high fuel consumption.
Replacement Parts
The emission control systems on the engine were designed, built and certified to conform with EPA and California emissions
regulations. We recommend the use of genuine our parts whenever you have maintenance done. These original-design replace-
ment pads 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 gasoline’s are being blended with alcohol or an ether compound. These gasoline’s 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.
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.
