1. Preventive Maintenance: Regularly checking and servicing equipment to avoid problems. Such as, oiling a bicycle chain.
2. Corrective Maintenance: Fixing equipment after it has broken down. Such as, repairing a flat tire.
3. Predictive Maintenance: Using technology to predict potential failures before they occur. For example, monitoring car engine sounds.
4. Scheduled Maintenance: Following a fixed timetable for maintenance. For example, servicing a generator every six months.
5. Routine Maintenance: Day-to-day small fixes and care.For example,cleaning a fan or replacing light bulbs.
