Consolidated from the prevention measures in Chapters A–I. Adjust frequencies to the manufacturer’s schedule and your site’s maintenance history.
| Frequency | Tasks |
|---|---|
| Every 30 minutes | Fill-weight check; visual capsule inspection. |
| Every shift | Clean guide tracks, feed path and discharge chute. Inspect the separation station. Clean the vacuum filter. Check safety devices. |
| Every batch | Check vacuum, air and locking pressure. Verify dosing settings and calibration. Clean the dosing disc, dosing unit and closing station. Clean the powder feeder filter. Empty the dust collector bin. Challenge the reject system. Complete line clearance. |
| Daily | Drain air filters and compressor condensate. Clean the separator bush and sensors. Inspect tamping pins, feeder hoses and safety doors. Check PLC inputs. |
| Weekly | Inspect vacuum and air hoses, O-rings, cap holders, locking components and sensor mountings. Check closing alignment, chain tension and motor temperature. Inspect the agitator drive and compressor. Grease cams. General mechanical inspection. |
| Monthly | Inspect separator plate, dosing disc, guide plates, cams, closing cam, bearings and shaft seals, couplings and pneumatic cylinders. Check locking force and machine level. Test all emergency stops. Clean electrical cabinet filters; inspect fans, panels and communication cables. |
| Quarterly | Inspect solenoid valves and electrical terminals. |
| Annually | Insulation resistance testing. |
| Scheduled PM | Replace tamping pins, closing pins and seals at wear limits. Check shaft alignment, indexing, transmission, encoder and PLC modules. Change gearbox and vacuum pump oil. Back up the PLC program. |
