is added to water, never the other way round!
2. The solution is not dangerous, but it is necessary to work carefully with it. Remove spilt drops with clean
water.
3. Before filling leave the solution to cool down. Observe the prescribed quantity of hydrated lime.
4. The solution must not get in contact with metal parts and the electric installation! The solution is not
harmful for the tube valve.
5. The antifreeze solution with the above mentioned composition must not be used in the cooling system!

1. Unload the tyre by lifting the tractor and turn it with the
valve upwards (A).
2. Deflate the tyre and unscrew the valve insert; turn the

During draining of liquid vacuum may occur in
the tyre. Therefore, turn the wheel time after time to
get the valve to the upper position (B).
3. Remove the rest of the liquid after screwing on the
adapter for water filling by supplying pressurized air (C).
4. Blow out the liquid until it stops running through the
