Engine Air Filter Cleaning/Check
A dirty air filter limits the passage of air, thus reducing engine performance. When working in particularly
dusty areas, clean or replace the filters more often than specified in the maintenance programme.
WARNING:
Running the engine without air filters, or with damaged filters, can cause a faster
engine wearing.
