14 Emission Control Systems Information and Warranty
The Emission Control Warranty and associated information is valid only for the U.S.A., its territories, and
Canada.
14.1
Emission Control System Background Information
Introduction
Wacker Neuson spark-ignited engines/equipment must conform with applicable Environmental
Protection Agency (EPA) emissions regulations. There are two types of emissions that fall under these
regulations: 1) exhaust, and 2) evaporative. These regulations require that manufacturers warrant the
emission control systems for defects in materials and workmanship.
Furthermore, EPA regulations require all manufacturers to furnish written instructions describing how to
operate and maintain the engines/equipment including the emission control systems. This information is
provided with all Wacker Neuson engines/equipment at the time of purchase.
Exhaust 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 Neuson utilizes lean carburetor settings and other systems to reduce the emissions of carbon
monoxide, oxides of nitrogen, and hydrocarbons.
Evaporative Emissions
Evaporative emissions are fuel emissions and generally include emissions that result from permeation
of fuel through the fuel-system materials or from ventilation of the fuel system.
Wacker Neuson utilizes low-permeation fuel lines and fuel tanks where applicable to reduce evaporative
emissions.
Problems that may affect Emissions
If any of the following symptoms arise, have the engine/equipment inspected and repaired by a Wacker
Neuson dealer/service center.
Hard starting or stalling after starting
Rough idling
Misfiring or backfiring under load
Afterburning (backfiring)
Presence of black exhaust smoke during operation
High fuel consumption
Tampering and Altering
Tampering with or altering the emission control system may increase emissions beyond the legal limit.
If evidence of tampering is found, Wacker Neuson may deny a warranty claim. Among those acts that
constitute tampering are:
Removing or altering of any part of the air intake, fuel, or exhaust systems.
Altering or defeating the speed-adjusting mechanism causing the engine to operate outside its design
parameters.
14.2
