What really happens during a repair?

Many of you have probably wondered what really happens during a repair. Here is an example based on an ETV-ST-61 repair:

1. We check for any special customer requests, maintenance contracts and possible technical updates, and when the tool was last at our workshop.

2. We inspect the tool visually — inside and out. Then we do a preliminary test of the tool’s operation and measuring abilities, and of any accessories that may be installed (a scanner, etc.).

3. Then we save data from the tool’s memory, such as calibration values, number of tightening cycles, etc.

4. We take the tool completely apart to clean and inspect the components (such as bearings and gears) for defects and wear.

5. All relevant information is input to the system: customer’s description of the problem, service technician’s findings, replacement parts needed, and photos of the unit’s condition, if appropriate.

6. A cost estimate is prepared (only for customers who have not yet entered a maintenance or repair contract with approval limits).

7. As soon as all necessary parts have arrived from the central warehouse,
they are replaced, and the tool is reassembled.

8. All lubricants and operating fluids are replaced according to manufacturer specification.

9. Inspections: Safety, electrical (earth conductor resistance, insulation resistance, earth conductor current). Tests: All tool functions, including any accessories installed (angle test, rotation speed, offset, scanner, etc.).

10. Standard final test (10 measurements with printout) according to Atlas Copco specifications, if the customer doesn’t want a machine capability check or calibration.

11. A repair report is prepared for the customer. This includes appropriate additional notes if we have noticed further problems during repair (e.g. maintenance interval significantly exceeded, associated damage to gearbox, liquid has penetrated the unit).

12. Delivery note, shipment and invoicing.

The following services are also included:

13. A record of all relevant data on the work completed.

14. Packaging and shipping the tool free of charge.

15. Proper disposal of used lubricants, operating fluids and faulty parts.

16. A full three-month warranty on spare parts.

17. Updating the tool’s software to the latest version, if possible. (This ensures that the tool is always up to date.)

Altogether, employees in the receiving and shipping areas, the workshop and the service support team, check more than 60 points before the unit leaves our workshop again.
