OPERATION
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.
