1、数显拉力机在试验之前，必须保证系统提取预热20分钟以上，从而使温度影响降低到最小。

1, before the test, it is necessary to ensure that the system is extracted and preheated for more than 20 minutes, so that the effect of temperature is reduced to a minimum.

2、缓冲器用油应保持清洁，油面高度不足筒深三分之二时，应立即换掉。

2. The oil of the buffer should be kept clean. When the height of the oil surface is less than 2/3, the oil should be replaced immediately.

3、数显拉力机开机前，检查摩擦活动部位是否应加注润滑油。

3. Before the machine is opened, check whether the friction parts should be added to the lubricating oil.

4、在加持试片前，必须将制动手柄卡住，加好试片后放开。

4. Before holding the test piece, the brake handle must be stuck, and the test piece will be released.

5、测力计主轴承不允许加油。变速箱内摩擦轮表面不得加油或溅有油渍，摩擦面应绝对清洁干净，不得将摆臂上的斜面块猛烈冲击。

5, do not allow the gas main bearing dynamometer. The surface of the friction wheel in the gearbox shall not be refueled or splashed with oil stains. The friction surface should be absolutely clean and clean, and the slope block on the arm should not be violently impacted.

6、试验完毕，切断电源后，再给试验机作表面清洁处理，及时进行防护，以防表面生锈。

6. After the test is finished, the power supply is cut off, and the surface cleaning treatment is made to the test machine, and the protection is carried out in time to prevent the surface rust.
