4 - Sprayer setup47Counter WeightTo improve stability on articulated models, extra weight can be addedby means of liquid-filled tyres.The standard tyre valve is an universal air-water valve. The tyres may befilled with liquid to max. 75% of their total volume.Use a mixture of water and CaCl2 (calcium chloride) to avoid frostdamage as described below:200 g CaCl2 per litre of water gives protection to -15 °C.300 g CaCl2 per litre of water gives protection to -25 °C.435 g CaCl2 per litre of water gives protection to -35 °C.Filling the tyres1. 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 valvebody again.4. Adjust tyre pressure and lower the wheel. Please refer to “TyrePressure” on page 106.€ DANGER! It is very important that the CaCl2 is added to the water and agitated, until it is fully dissolved. Never pourwater on to CaCl2! If you get CaCl 2 in your eyes, flush instantly with cold water for at least 5 minutes and seek medicaladvice afterwards.± WARNING! The tyres must be liquid filled to max. 75 % of total tyre volume. Fill only the quantity. of liquid necessaryto obtain sufficient stability of the sprayer. Do not fill liquid and CaCl 2 mixture in tyres without tubes!μ ATTENTION! When filling the tyres, the valve should be positioned at 12 o’clock, and when adjusting the tyre pressurethe valve should be positioned at 6 o’clock.Emptying the tyres1. Rotate wheel until the valve is positioned at “6 o’clock”.2. Remove the valve body and lead the liquid away. Retain the liquidin an appropriate container.3. To empty the tyre completely, the tyre is inflated and a thin draintube is led to the bottom of the tyre. The air pressure will nowempty the remaining liquid.4. Remove the drain tube, fit the valve and inflate the tyre to specifiedpressure. See “Technical Specifications” in the table “Tyre pressure”.μ ATTENTION! Disposal of CaCl2 has to take place according to local legislation.
