- Look for oil leaks or air leaks
- Verify safety guards are in place
- Check electrical connections
2. Cleaning (10 minutes)
- Wipe down product contact surfaces
- Clean film path and rollers
- Remove product debris from seals
- Clean photoeyes and sensors
- Clear conveyor belts
3. Lubrication (5 minutes)
- Check oil levels in gearboxes
- Apply grease to designated points
- Verify air line lubricator level
- Check chain lubrication
- Inspect oil for contamination
During Operation Monitoring
4. Performance Checks
