With lifting the tractor, relief the tire and turn the wheel with the valve aiming up.
(A).
−
Drain the air off the valve and unscrew the valve element from the air tube. Then
turn the valve with the valve aiming down.
When draining the liquid off the air tube, vacuum may arise in the tire.
Therefore, from time to time, the wheel should be turned to the top position of
the valve (B).
−
Remove the remaining portion of liquid with screwing on the adapter for filling wa-
ter and supply the compressed air (C) and keep removing the liquid until the liquid
stops flowing from the air adapter.
−
Remove the water-filling adapter, screw back the pneumatic section of the valve,
and inflate the tire to the prescribed pressure (D).
−
After the inflation, screw the protecting cap on the valve.
−
Analogously proceed when treating the second tire.
