2.7.8. Filling tyres with water
It is used for lowering the machine gravity centre. An advantage is that the solution in tyres does not increase the axle load.
The inner space of the tyre is lled with the solution of water, slaked lime (calcium hydroxide) and anhydrous calcium chloride CaCl
2
or
magnesium chloride MgCl
2
. The mixing ratios for individual temperature per one tyre are given in the table.

A ller neck can be ordered as a replacement part under number
4-322839.
Filling procedure:
Move the machine to a rm base. The lling valves should be
•
in the extreme upper position. Secure the drum with blocks
on both sides.
Unscrew the removable valve insert and screw on the ller
•
neck.
Mount the hose from the lling equipment (a tank located
•
above, pump, etc.) on the ller neck and ll the tyres with
the solution.
During the lling, air escapes from the tyre through the side
•
opening from the ller neck. The tyre is suciently lled (at
75%) when the solution starts owing out through the ope-
ning.
Unscrew the ller neck, screw the valve insert back on, and
•
inate the tyre to a pressure of 160 kPa (23,2 PSI).
