# Quick start checklist after spare-part replacement

Step-by-step actions for tests, safety verifications and documentation so machines and systems run safely and quickly after a spare-part replacement.

14 September 2026

## Quick answer

After a spare-part replacement, first run a function test, a safety check and complete documentation. Verify interfaces, seals and electrical connections. Start the equipment under observation and record serial numbers, measurements and the release decision.

## Overview: what this checklist delivers

The checklist helps you confirm technical function, ensure safety and record results. It reduces the risk of follow-up failures, unexpected downtime and unclear responsibilities.

## Before first start: visual and assembly checks

Check mechanical fastening, seals and lubrication points. Match part numbers and serials with the order. Remove tools and debris from the work area. Inspect cable routing, connectors and strain reliefs.

## Function test: staged and monitored

Start in manual or reduced-speed mode without load. Verify motion sequences, end positions and sensors. Watch for noise, vibration and temperature rise. Repeat cycles if needed and log values like current, pressure or temperature.

## Safety check: protective functions and emergency stop

Confirm guards, covers, interlocks and safety sensors. Test emergency stop, light curtains and door locks under realistic conditions. Make sure fault states are detected and the system stops safely.

## Electrical and electronic checks

Check grounding, insulation resistance and fuses. Verify voltages at relevant terminals. Test control and fieldbus communications and any software settings affected by the replaced part.

## Documentation and release

Collect test results in a protocol. Record part numbers, installation date, responsible technician, measurements and deviations. Define clear release criteria: deviations require rework or re-test. Store the protocol in the machine file and digital archive.

## Frequently asked questions

How detailed should the documentation be? Detail enough for a colleague to understand the status: part numbers, test values, cycles, observations and name/date of the tester are usually sufficient.

When is an external inspection needed? If the part affects safety-critical functions or regulations apply, use an external or certified inspector for final release.

What if measured values are out of range? Lock out the equipment, report the finding to maintenance or design, document the deviation and plan rework or replacement.

How long should observation run after start-up? It depends on complexity. Simple parts often need hours under observation. Critical components may require days with logged cycles.
