What are the safety precautions for coupling installation and maintenance?
Safety precautions for coupling installation and maintenance:

1. Couplings and other rotating parts must be protected by a cover. You may be injured if you touch these working parts.
2. In order to prevent danger, protective devices must be installed.
3. The power supply must be cut off during installation and disassembly.
4. Fastening bolts and countersunk bolts should be tightened with appropriate force using a screwdriver, wrench or torque wrench.
5. The working speed of the product cannot exceed the maximum speed.
6. It is forbidden to disassemble or reassemble the product.
7. Please work within the tolerance range. Working when the deviation exceeds the allowable value may cause damage to the coupling and may adversely affect the system using the coupling.
8. The torque generated by continuous operation cannot exceed the rated torque. Failure to do so may damage the coupling, or may adversely affect the system in which the coupling is used.
9. When fastening, use the bolts specified by us (fastening bolts and countersunk bolts) instead of other products.
10. Do not work in an environment that will adversely affect the product.
11. If you hear abnormal noise, please stop the rotating machinery immediately. Check the deviation of the machine, whether the shafts are in contact with each other, whether the bolts are loose or fall off, etc.
12. If the rotating machinery you are using works under the condition of relatively large load changes, please use anti-loosening glue on the bolts to prevent them from falling off, or use a coupling of a larger size.
13. When discarding, please ask a special person to dispose of this kind of product to avoid damage to the environment.
14. Do not touch the coupling just after finishing the work. You could be burned by the hot surfaces on which the coupling is used.

Summarize:
In order to work safely, please pay attention to the above points when installing and maintaining transmission products such as couplings, so as to avoid personal and property losses.
