MAINTENANCE
Intake Filter
The intake foam filter limits snow ingestion into the intake system.
When operating in loose powder snow, check the top of the foam filter
periodically to remove any accumulation of snow.
CAUTION
Operating the snowmobile with the intake filters removed may
cause carburetor icing. The result will be poor fuel economy or
carburetor malfunction. Always reinstall the intake filters before
operating the snowmobile.
