Operation 8 - Clean The Cab Air Filters; External Filters - New Holland T7030 Operator's Manual

OPERATION 8
CLEAN THE CAB AIR FILTERS
Air drawn into the cab by the blower fan passes
through three filters, two externally mounted, and
one recirculation filter located inside the cab.
Before servicing the filters, switch off the blower and
close the roof hatch, all windows and one door.
Forcibly close the other door. The resulting back
pressure will dislodge most of the loose dirt from the
underside of the external filters.
NOTE: In humid conditions, do not switch on the
blower prior to servicing the filter. Damp particles
drawn into the filter may be difficult to remove without
washing.

External Filters

To remove the external filter, unscrew the securing
clip (1) Figure 23, from the front end of the filter cover
(2).
Remove the cover (2) Figure 24, and the filter
element (3).
NOTE: The filters are made of specially treated
media with a rubber sealing strip bonded to the upper
surface. Take care not to damage the element during
removal.
Clean the elements by blowing with compressed air
not exceeding 30 lbf. in
the upper surface through the element to the
underside. Hold the nozzle at least 12 in. (300 mm)
from the element to prevent damage to the filter
media
Clean all filter chambers with a damp, lint-free cloth.
Re--install the filter elements with the clean side
uppermost and re-install the covers.
