一、800吨液压机液压油的存放。液压油要用专门的油桶进行存放、密封盖好，放到温度恒定的屋内进行存放。以免天冷密封性不好进入空气凝结成水汽影响油质，避免因铁桶生锈脱落参杂进液压油影响机器的正常使用。
2., for the hydraulic pump station system of the hydraulic press used in winter, there are steps to keep warm and cover up the protection.
3. often check and maintain the hydraulic system and replace the working hydraulic oil (in principle, replace the hydraulic oil every 2000 hours). Of course, the replacement of hydraulic oil is very good for winter use. In addition, it is necessary to do a good job in the antifreeze work of the oil tank of the oil press. The second is to do a good job in the lubrication of various parts of the 800-ton hydraulic press, and to add lubricating oil regularly, especially the guide rail contact surface of the machine.
Before working, the 4. hydraulic press should be preheated for more than 30 minutes, and the machine should be operated several times without load before processing.
