The tire is to be filled up as per standards (to 75% of its volume). Water (solution) leakage
through a combined valve outlet is an indicator that the tire is filled up. As soon as the tire
is filled up, screw the nipple back and pressure the tire up to its operative standards.
It is required to add CaCl
2
in water on the basis of 300 g/l of water (a freezing-point is
25 ° С ) in cold seasons.
IMPORTANT! When preparing a solution, do not pour water in CaCl
2
to avoid formation
of hardly dissoluble clots of calcium chloride.
If a tractor is equipped with a front hitch linkage, a longitudinal stability of the agricultural
aggregated unit can be provided with combined machines of front and rear location.
