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 requirements.
Operation on Public Lands in the U.S.A.
Your POLARIS vehicle has a spark arrester that was tested and qualified to be in accordance with the USFS stan-
dard 5100-1c. Federal law requires that this spark arrester 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 420. Violations are subject to
monetary penalties. Federal regulations can be viewed online at www.gpoaccess.gov/ecfr/.

This engine is equipped with a closed crankcase system. Blow-by gases are forced back to the combustion cham-
