Machine Preparation
| NOTICE |
|---|
When the rotor is at operating temperature, the rotor coolant is hot. The coolant is also under pressure. Any contact with hot coolant or with steam can cause severe burns. Allow rotor to cool before the coolant level is checked or the coolant is drained. Ensure that the fill plug is cool before removing the plug. The plug must be cool enough to touch with a bare hand. Remove the plug slowly in order to relieve pressure. Cooling system conditioner contains alkali. Alkali can cause personal injury. Do not allow alkali to contact the skin, the eyes, or the mouth. |
| NOTICE |
