Engine Intake Restrictor Plate

Some RANGER 800 models are equipped with an intake restrictor plate
in order to meet vehicle class regulations. This plate MUST NOT be
removed for any reason. Removal of the intake restrictor plate will void
the warranty on the vehicle.

Periodic Maintenance Chart beginning on page 57. Always change the
oil filter whenever changing oil.
WARNING! Vehicle operation with insufficient, deteriorated, or contaminated
engine oil will cause accelerated wear and may result in engine seizure,
accident, and injury. Always perform the maintenance procedures as outlined in
the Periodic Maintenance Chart.
