Servicing the Air Cleaner
Service Interval:
Every 400 hours (more frequently in
extremely dirty or dusty conditions).
Service the air cleaner earlier if the
air-cleaner indicator shows red.
Check the air-cleaner body for damage which could
cause an air leak. Replace it if it is damaged. Check
the whole intake system for leaks, damage, or loose
hose clamps.
Service the air-cleaner filter only when the service
indicator requires it. Changing the air filter before it is
necessary only increases the chance of dirt entering
the engine when you remove the filter.
Important:
Make sure that the cover is seated
correctly and seals with the air-cleaner body.
