Emission Control Systems
Noise Emission Control System
Do not modify the engine, intake or exhaust components, as doing so may affect compliance
with U.S.A. EPA noise control requirements (40 CFR 205) and local noise level require-
ments.
Operation on Public Lands in the U.S.A.
Your Polaris vehicle has a spark arrestor that was tested and qualified to be in accordance
with the USDA Forest Service Standard 5100-1C. Federal law requires that this spark arres-
tor be installed and functional when the vehicle is operated on public lands.
Operation of off-road vehicles on public lands in the U.S.A. is regulated by 43 CFR 8343.
Violations are subject to monetary penalties. Federal regulations can be viewed online at
www.gpoaccess.gov/ecfr/.
Crankcase Emission Control System
This engine is equipped with a closed crankcase system. Blow-by gases are forced back to
the combustion chamber by the intake system. All exhaust gases exit through the exhaust
system.
