Clean the Engine Air Precleaner
The engine air precleaner must be checked to be
sure that debris is not causing any obstruction at the
precleaner inlet.
To inspect the inlet to the precleaner, loosen the two
hose clamps (1) attaching boot (2) to the air cleaner
tube (3) and the precleaner (4).
Slide the boot toward the front of the tractor on the
tube. Inspect the inlet (5) of the precleaner, and
remove any debris accumulated in this area.
After the precleaner is cleaned, reinstall the boot and
tighten the hose clamps securely.
Loosen the clamp (6) and disconnect the aspirator
hose (7) where it connects to the precleaner aspirator
tube.
Inspect by looking down inside the precleaner aspirator
tube and remove any accumulated debris. Check that
the flapper door (8) is operating properly.
