Emission Control System Information
Problems Affecting Emissions
If aware of any of the following, have the engine inspected and repaired by an authorized POLARIS supplier:
•Hard starting or stalling after starting
•Rough idle
•Shut down or backfire after applying an electrical load
•Afterburning (backfiring)
•Black exhaust smoke or high fuel consumption
Replacement Parts
The emission control system on the engine was designed, built, and certified to conform to applicable emission regulations. We recommend the use of POLARIS Genuine parts whenever maintenance is performed. These original design replacement parts are manufactured to the same standards as the original parts. The use of replacement parts that are not of the original design and quality may impair the effectiveness of the emission control system.
Aftermarket part manufacturers assume the responsibility that the part will not adversely affect emission performance. The manufacturer or re- builder of the part must certify that use of the part will not result in a failure of the engine to comply with emission regulations.
