(1) 保持圆锥滚子轴承及其周围清洁。

(1) keep the tapered roller bearings and their surroundings clean.

即使是眼睛看不到的小尘埃，也会给轴承带来坏影响。所以，要保持周围清洁，使尘埃不致侵入轴承。

Even small dust that is not visible to the eye can cause bad effects on the bearings. So keep the area clean and keep the dust from invading the bearings.

(2) 小心谨慎地使用。

(2) use carefully.

在使用中给与圆锥滚子轴承强烈冲击，会产生伤痕及压痕，成为事故的原因。严重的情况下，会裂缝、断裂，所以必须注意。

In use, the tapered roller bearings are strongly impacted, resulting in scars and indentations, which become the cause of the accident. In severe cases, cracks and fractures occur, so attention must be paid.

(3) 使用恰当的操作工具。

(3) use proper operating tools.

避免以现有的工具代替，必须使用恰当的工具。

Avoid replacing existing tools with appropriate tools.

(4) 要注意圆锥滚子轴承的锈蚀。

(4) attention should be paid to the corrosion of tapered roller bearings.

操作轴承时，手上的汗会成为生锈的原因。要注意用干净的手操作，最好尽量带上手套。

When handling bearings, the sweat on the hands becomes the cause of rust. Be careful with clean hands, so you'd better wear gloves as much as possible.

圆锥滚子轴承利用听觉来辨识不规则的运转是一种很普通的方法，例子如借助电子式听诊器来查觉某一零件的不正常噪音是有经验操作员使用。轴承若是处于良好的运转状况会发出低的呜呜声音，若是发出尖锐的嘶嘶音圆锥滚子轴承、吱吱音及其它不规则的声音、通常表示轴承处于不良的运转状况。

Running roller bearings use hearing to identify irregular cone is a very common method, examples such as the use of electronic stethoscope to certain parts of the abnormal noise is experienced operator. If the bearing is in good working condition will make a low humming sound, if a sharp hissing sound of tapered roller bearings, squeaking sound and other irregular sound, usually expressed in adverse operating conditions of the bearings.
