EMISSION CONTROL SYSTEMS

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.

Exhaust Emission Control System

The emissions from the exhaust of this vehicle are controlled by engine

design, including factory-set fuel delivery and ignition. The engine

and related components must be m aintained at Polaris specifications to

achieve optimal perform ance.

Engine idle speed is the only adjustment Polaris recommends that the

operator perform. Any other adjustments should be performed by an

authorized Polaris dealer.

The RANGER TM emissions label (1) is located on the front of the

engine. Remove the service panel (2) to view the label. The label on

the RANGER 2X4 and 4X4 (3) is located on the recoil cover. Remove

the seat and look through the gap in the aluminum exhaust shield to

view the label.

NOTE: The installation of devices that effectively increase exhaust

emissions beyond their legal limits will void all manufacturer

warranties and may violate laws governing the registration

and operation of this vehicle.
