There are twotypes of emissions that fall under these regulations: 1) exhaust, and 2) evaporative.These regulations require that manufacturers warrant the emission control systemsfor defects in materials and workmanship.Furthermore, EPA regulations require all manufacturers to furnish writteninstructions describing how to operate and maintain the engines/equipmentincluding the emission control systems. This information is provided with allWacker Neuson engines/equipment at the time of purchase.Exhaust EmissionsThe combustion process produces carbon monoxide, oxides of nitrogen, andhydrocarbons. Control of hydrocarbons and oxides of nitrogen is very importantbecause, under certain conditions, they react to form photochemical smog whensubjected to sunlight. Carbon monoxide does not react in the same way, but it istoxic.Wacker Neuson utilizes lean carburetor settings and other systems to reduce theemissions of carbon monoxide, oxides of nitrogen, and hydrocarbons.Evaporative EmissionsEvaporative emissions are fuel emissions and generally include emissions thatresult from permeation of fuel through the fuel-system materials or from ventilationof the fuel system.Wacker Neuson utilizes low-permeation fuel lines and fuel tanks where applicableto reduce evaporative emissions.Problems that may affect EmissionsIf any of the following symptoms arise, have the engine/equipment inspected andrepaired 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
