components secure and in good condition to prevent
entrance of unfiltered air.
Overmaintenance can cause more damage than
good. Removing the air filter element more often
than is needed allows contaminants to enter the
engine unnecessarily. Clean or replace the air filter
element only when the restriction indicator indicates
excessive restriction in the system.
AIR FILTER RESTRICTION INDICATOR
The air filter restriction indicator signals when to
change the air filter element. Check the restriction
indicator daily. The red indicator gradually becomes
visible as the air filter element loads with dirt.
Replace the filter element when the red indicator of
the air filter restriction indicator locks in the visible
position.
When the red indicator is locked in the visible
position, the indicator may return to the non---visible
position when the engine is shut off. It will return to
the visible position when the engine is started. After
replacing the air filter element, reset the service
indicator by pushing the “reset” end of the indicator.
