Periodic checklist: ten checks before a repair is needed

A periodic inspection can follow the same sequence each time:

1. environment and signs of unusual moisture or heat;
2. dust, dirt and residues;
3. corrosion or surface changes;
4. loose screws, jacks and components;
5. cables, power supplies and batteries;
6. moving parts and controls;
7. essential functions;
8. rarely used functions;
9. case, bag and internal materials;
10. maintenance log update.

You do not need to dismantle the item to complete the checklist. The goal is to identify what has changed and decide whether routine care is enough or technical inspection is needed.
