7.7.6.1 Fresh Air Intake Filter
The fresh air filter is located under the right cab-
forward side platform, and should be serviced
every 50 hours under normal conditions, and more
frequently in severe conditions.
Service the filter as follows:
DANGER
Stop engine and remove key from ignition
before leaving Operator’s seat for any reason.
A child or even a pet could engage an idling
machine.
a. Move right cab-forward side platform towards rear
(cab-forward) of windrower to expose intake
housing.
b. Release latch (A), and open filter housing door
(B).
c. Pull filter (C) out of housing.
d. Clean filter as follows:
1. Pat sides of element gently to loosen dirt. Do
not tap element against a hard surface.
2. Using a Dry Element Cleaner Gun, clean
element with compressed air.
3. Hold nozzle next to inner surface, and move
up and down pleats.
IMPORTANT
Air pressure must not exceed 100 psi (700
kPa). Do not direct air against outside of
element, as dirt might be forced through to
inside.
4. Repeat steps 1. to 3. to remove additional dirt
as required.
e. Inspect filter before installing as follows:
1. Hold a bright light inside element, and check
carefully for holes. Discard any element which

gasket is damaged or missing, replace
element

element.
