When operating the machine, the points to note are as follows: before cutting, adjust the tool properly and clamp the workpiece, and the stop plate must also be secured; after a trial run in the sequence of clamping then releasing, forward then backward, work can begin. While the machine is rotating, no part of the human body may come into contact with any rotating part. During operation, cuffs must also be fastened, which helps prevent injury from rolling, impact or crushing by the tube. Check that the dust collection device is in good condition before cutting. When using an abrasive cut-off machine, check in advance whether the grinding wheel is chipped or cracked or has absorbed moisture, and whether the power cord is reliable. Changing tools, measuring workpieces, lubricating and cleaning tube ends must all be carried out with the machine stopped.

Maintenance of the paper core machine is also very important:1, when the paper core machine starts working, we should reduce the speed or set it directly to the lowest point. This avoids mechanical damage.2, if a problem occurs with the paper core machine, cut off the power as soon as possible and have it repaired by a professional. Do not repair it yourself and never repair it while it is still connected to power, as this creates a risk of electric shock.3, the power supply should adopt a three-phase four-wire system to avoid the risk of electric shock. In fact, there are many other precautions throughout the entire operation process; what is needed most at work is care and attention.
