Determining if an oval printing machine needs maintenance hinges on daily inspections and periodic checks. You can quickly identify problems using the "five senses inspection method": Visually inspect for loose bolts and damaged power cords; listen for abnormal noises during operation; touch the machine to feel for abnormal vibrations or overheating; smell for any burnt odors. Simultaneously, regularly check the usage counter and perform maintenance according to the manufacturer's recommended schedule.
Specific inspection items include:
1. Bolt tightness: Visually inspect all visible bolts to ensure they are tight; this is crucial to preventing equipment vibration and displacement.
2. Power cord integrity: Check for damaged insulation on the power cord and ensure the terminals are secure to prevent leakage or short circuits.
3. Abnormal noise or vibration: Listen for unusual noises during operation and touch the machine to feel for abnormal vibrations; these may indicate bearing wear or loose components.
4. Control Panel Malfunction Signs: Observe for fault codes or alarm messages displayed; these are important indicators of equipment self-checking.
5. Regular Use of Counters: Record equipment operating time. Maintenance is required even if no abnormalities are observed when the manufacturer-specified maintenance cycle is reached.
