| Step | Operation | Criterion |
|---|---|---|
| Step 1: Check Socket | Try a different socket known to be working | Works on new socket → original socket dead or has poor contact |
| Step 2: Check Power Cord | Inspect both plugs for looseness and cord for damage | Loose → plug in firmly; damaged → replace cord |
| Step 3: Check Circuit Breaker | Check if air switch next to machine has tripped | Tripped → reset and retry; trips repeatedly → internal short circuit, stop use and request repair |
| Step 4: Check Fuse | Open electrical control box and inspect fuse | Blown → replace with same spec fuse; burns again → component short circuit |
One-Sentence Summary: 80% of power issues are socket or power cord problems, not a broken machine.
Prevention: Use a dedicated power cord with overload protection for the machine. Do not share a power strip with other high-wattage equipment.
