 Danger !

Risk of injury to skin and eyes suffering scalding from contact with hot coolantspray. Risk of poisoning from swallowing coolant.

Do not open cooling system unless coolant temperature is below 90 °C. Open cap slowly and release the pressure. Do not pour coolant into beverage containers.
Wear protective gloves, protective clothing and safety glasses.

AS20.00-Z-0001-01A

 Danger !

Risk of injury caused by touching hot retarder and by scalding from hot retarderoil. Risk of injury to skin or eyes caused by retarder oil escaping under high pressure

Do not carry out any work unless retarder is switched off. Wear suitable protective clothing and safety glasses when working on the hot retarder.
