Machine manufacturing may end at delivery, but investment success begins with daily operation. Effective after-sales support transfers knowledge to the plant team and turns maintenance from a reaction after failure into a system that protects uptime and product quality.
1. Installation and commissioning
Before delivery, verify foundations, utilities and access routes. During commissioning, check safety devices, motor directions, sensors and recipes, then complete an agreed acceptance run with the intended product and package. Record achieved output, product quality, waste and remaining actions before final handover.
2. Train each role for its work
Operators need safe start-up, recipe selection, changeover, cleaning and alarm response. Maintenance technicians need drawings, sensor and motor checks, backups and systematic troubleshooting. Production supervisors need performance indicators and planned-downtime coordination. Hands-on training with a checklist is more valuable than a short general presentation.
3. Build an executable preventive-maintenance plan
Create daily, weekly and monthly tasks, then link major work to operating hours or cycles. Tasks may include cleaning, inspection, lubrication, connection checks, temperature or vibration observation, safety-device tests and instrument calibration. Record completed work and findings instead of relying on memory.
| Level | Examples | Owner |
|---|---|---|
| Every shift | Cleaning, leaks, unusual noise and guards | Operator |
| Short interval | Lubrication, belts, chains, sensors and connections | Maintenance |
| Planned shutdown | Full inspection, calibration, wear parts and backups | Maintenance with technical support |
4. Stock spare parts according to risk
You do not need every component on the shelf. Prioritise parts whose failure stops the entire line, parts with long lead times and regular consumables. Classify them by criticality, lead time and usage, and set minimum stock levels. Record each part number, photograph and machine location to speed ordering and replacement.
5. Keep documents and backups current
The line file should include operation and maintenance manuals, electrical and mechanical drawings, parts lists, protection settings, PLC and HMI backups, and a change log. After every software or mechanical modification, update the controlled master copy so improvements are not lost when a controller or panel is replaced.
6. Define support and escalation
Agree on the support channel, required incident data, service hours and expected response. A useful report includes machine identification, a clear symptom, when it started, alarm-screen photographs, checks already completed and a short safe video when appropriate. Good information reduces diagnosis time and quickly determines whether remote help or an on-site visit is needed.
7. Track a small set of indicators
- Downtime: hours in which the line could not produce.
- MTBF: mean operating time between failures.
- MTTR: mean time to repair and restore production.
- Waste and quality: rejected product or packages after stops and restarts.
- Maintenance compliance: preventive tasks completed on schedule.
A practical first 90 days
Days 1–30: stabilise operating and cleaning methods, save backups and log observations. Days 31–60: review recurring faults, adjust spares and refine maintenance intervals. Days 61–90: review output and quality, then deliver targeted refresher training and documented improvements.
