For assembled cones, rotating the components in the solvent to remove particles and preservative.5.1.4.2 从溶剂中取出轴承，然后用溶剂喷雾剂彻底喷洒至少10秒钟。在此期间，应边
12、清洗边让冲洗物流入容器。对组装后的轴承应边转动边清洗。分开清洗每一个部件，然后立即干燥。最后用防锈材料如Quaker FERROCOTE 5856BF T1将轴承重新防护。Remove the bearing from the solvent and wash thoroughly with a fine spray of hexane from the wash bottle for at least 10 seconds. During this step, all washing should drain into the container. Cone assemblies shoul
13、d be rotated. Wash each component and then immediately dry. preserve the bearing with Quaker FERROCOTE 5856BF T1注意：轴承部件用一个过滤盘。由于溶剂烟雾是危险的，所以整个清洗过程必须在实验室环境下进行。不可接触皮肤。在整个操作过程中，可使用钳子或塑料手套处理轴承部件。但只有（经过含污量）证实的防尘手套可使用（聚乙烯手套）。避免使用已破损，有斑点的手套。NOTE: Use one filter disk for five bearings.
