Emissions Control Systems Information and Warranty

12 Emissions Control Systems Information and Warranty: KUBOTA

The Emission Control Warranty and associated information is valid only for the 

U.S.A., its territories, and Canada.

12.1

Emission Control System Background Information

Introduction

Wacker Neuson engines/equipment must conform with applicable Environmental 

Protection Agency (EPA) and California Air Resource Board (CARB) emissions 

regulations. These regulations require that manufacturers warrant the emission 

control systems for defects in materials and workmanship.

Furthermore, EPA and CARB 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.

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.
