Before operating a fully automatic cutting machine, give it a thorough "full-body checkup": inspect the blade to ensure it is sharp and free of nicks-much like checking if a chef's knife needs sharpening. Verify that the safety guard is securely in place-a step just as crucial as putting a protective case on your mobile phone. Finally, inspect the power cord to ensure it is intact and tangle-free, avoiding the messy knots often seen in mop cords. Next, let the machine "warm up": after connecting the power supply, let it run idle for one minute while listening for any abnormal noises and observing whether the indicator lights illuminate correctly-much like warming up a car engine before driving.
Finally, prepare the material to be cut, ensuring that its surface is flat and free of impurities; otherwise, the cutting process could be as arduous as trying to cut fabric with a pair of dull scissors.
