DANGER! It is very important that the CaCl2 is added to the water and agitated until it is fully dissolved. Never
pour water on to CaCl2! If you get CaCl2 in the eyes, flush instantly with cold water for at least 5 minutes and seek
medical advice afterwards.
WARNING! The tyres must be liquid filled to max. 75 % of total tyre volume. Fill only the qty. of liquid necessary to
obtain sufficient stability of the sprayer. Do not fill liquid and CaCl2 mixture in tyres without tubes!
ATTENTION! When filling the tyres the valve should be positioned at 12 o’clock and when adjusting the tyre pres-
sure, the valve should be positioned at 6 o’clock.
ATTENTION! Disposal of CaCl2 has to take place according to local legislation.
TO EMPTY THE TYRES:
1. Rotate wheel till the valve is positioned at “6 o’clock”.
2. Remove the valve body and let out the liquid. Retain liquid in an
appropriate container.
3. To empty the tyre completely the tyre is inflated and a thin drain
tube is lead to the bottom of the tyre. The air pressure will now
empty the remaining liquid.
4. Remove the drain tube, fit the valve and inflate the tyre to specifi-
ed pressure. See the table “Tyre pressure”.
To improve stability on articulated models, extra weight can be
added by means of liquid-filled tyres. The standard tyre valve is an
universal air-water valve. The tyres can be filled with liquid to max.
75% of their total volume.
Use a mixture of water and CaCl2 to avoid frost damage as descri-
bed below:
200 g (7.1 oz) CaCl2 per litre water gives protection to -15°C (30.6°F)
300 g (10.6 oz) CaCl2 per litre water gives protection to -25°C (12.6°F)
435 g (15.4 oz) CaCl2 per litre water gives protection to -35°C (-5.4°F)
TO FILL THE TYRES:
1. Jack up the wheel and rotate wheel till the valve is positioned at
“12 o’clock”.
2. Remove the valve body and fill liquid until it reaches the valve.
3. When surplus liquid is drained through the valve stem fit the valve
body again.
4. Adjust tyre pressure and lower the wheel. (Please refer to table for
correct tyre pressure).
