. AIR PRESSURE
131
TIRE PRESSURE–
Check the pressure once a week or
every 50 hours of operation (fig. 131-5). Never inflate a tire
more than the recommended maximum air pressure. Use an
air line with a locking air chuck and stand behind the tire
tread while filling (fig. 131-6).

FIG 131-6
NOTE:
Tire pressure will depend on tire type
and load quantity in solution tanks.
Refer to page 20 for tire specifications.
When inflating tire use extension hose with in-line air
gauge and clip-on air chuck, which allow operator to
stand clear of tire side wall explosion trajectory.
WET TANK–
Drain the wet tank (fig. 131-3) daily to prevent sys-
tem condensation from contaminating the engine air compressor or
dryer.
AIR TANK–
Drain the air
tank (fig. 131-4) daily by slowly
releasing the drain cock. Check
for moisture in the system. If there
is excessive moisture in this tank, there may be a problem with the sys-
tem. Call Hagie Customer Support for assistance.

AIR BAG PRESSURE–
The airbags (131-1) automatically adjust pres-
sure to compensate for load weight and field conditions. The
system includes an air dryer (fig. 131-2) that dries the air
coming from the air compressor before sending it to a collec-
tion tank. Check the dryer cartridge every 50 hours to make
sure that it is purging with compressor unload. Change the
cartridge as needed or every other season (1000 hours).
From the collection tank, the air is sent to the airbags located on the legs (fig. 131-1) as needed to main-
tain a level pressure. There are control valves on each leg that open and close to allow air in.
Visually check the air bags daily for leaks and cracking. If an air bag seems to be low check the bag for
any punctures or leaks. Call Hagie Customer Service for repairs.
