Emission Control System 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.
Emission Control System Information Replacement Parts The emission control systems on your Wacker Neuson engine were designed, built, and certified to conform with EPA and California emissions regulations. We recommend the use of genuine Wacker Neuson parts whenever you have maintenance done. These originaldesign replacement parts are manufactured to the same standards as the original parts, so you can be confident of their performance.
Emission Control System Information 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.
Emission Control System Information 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 Neuson recommends that you retain all receipts covering maintenance on your engine, but Wacker Neuson cannot deny warranty coverage solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance.
Emission Control System Information TO OBTAIN WARRANTY SERVICE: You must take your Wacker Neuson product along with proof of original purchase date, at your expense, to any Wacker Neuson 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.
