1. The dry running test of the torsion spring machine must be carried out after the foundation is completely dry.
2. Check whether there is any foreign body in each part of the torsion spring machine, and whether there are slackness in each connecting piece and fastener.
3. Check whether the lubrication circuit of the torsion spring and the hydraulic pipeline are connected correctly, whether the amount of oil used for lubrication and hydraulic pressure is appropriate, whether the oil level is appropriate, and whether the lubrication part is properly lubricated.
4. A separate inspection test is needed for the auxiliary equipment of the torsion spring machine before it is running to verify whether its performance meets the specified requirements.
