1、螺栓直徑的大小對控制精度有一定的影響，施工中應用相同型號的螺栓連接付來標定扭矩值，而且使用一段時間后還應進行檢驗校定。

1. The size of the bolt diameter has a certain impact on the control accuracy. During construction, the same type of bolt connection should be used to calibrate the torque value, and after a period of use, it should also be inspected and calibrated.

2、工作前應開機空轉3-5分鐘。操作中如發(fā)現(xiàn)電機火花大，聲音異常，扭矩不穩(wěn)定時，應立即停機檢查，切勿帶病工作。

2. Before starting work, the machine should be turned on and idle for 3-5 minutes. If there is a large spark, abnormal sound, or unstable torque in the motor during operation, the machine should be stopped immediately for inspection. Do not work with a problem.

3、定期清洗和更換油脂，一般在工作5000次后，應進行一次清洗加油，以延長使用壽命。

3. Regularly clean and replace grease. Generally, after 5000 operations, a cleaning and oiling should be carried out to extend the service life.

4、主機上的電源開關，碳刷，控制儀上的保險絲等均屬易損件，容易引起故障，應經(jīng)常檢查，及時更換。

4. The power switch, carbon brush, and fuse on the controller on the host are all vulnerable parts that can easily cause malfunctions. They should be checked regularly and replaced in a timely manner.

5、使用中如發(fā)現(xiàn)工具上的螺釘松動，應及時緊固。

5. If the screws on the tool are found to be loose during use, they should be tightened in a timely manner.

6、搬運工具時不可提拉電纜線，并注意輕拿輕放，防止震動和摔碰。不用時應放在通風干燥處。如發(fā)現(xiàn)受潮應及時進行干燥處理。不可與酸、堿等有害物質(zhì)氣體接觸或存放在一起。

6. When transporting tools, do not lift the cables and handle them gently to prevent vibration and impact. When not in use, it should be placed in a ventilated and dry place. If moisture is found, it should be dried in a timely manner. Do not come into contact with or store together with harmful substances such as acids, alkalis, etc.
