Blade and Cutting Edge |
Before each shift and after abnormal cutting |
Inspect the blade for cracks, chips, deformation, corrosion, and excessive wear. Replace damaged blades and confirm that the cutting edge is correctly seated and secured. |
Apply lockout and tagout before blade removal. Use cut-resistant gloves during handling and keep guards installed during operation. |

Machine Guards and Interlocks |
Daily visual check; functional test weekly |
Check fixed guards, hinged covers, transparent shields, fasteners, and interlock switches. Confirm that the machine cannot operate when a required guard is open. |
Stop production immediately if an interlock fails. Never bypass, remove, or permanently defeat a guard or safety switch. |

Emergency Stop System |
Daily visual check; function test monthly |
Inspect emergency-stop buttons, pull cords, reset controls, and warning labels. Verify that stopping the equipment removes the hazardous motion and that a manual reset is required. |
Test only under controlled conditions with the cutting zone clear. Do not use the emergency stop as a routine operating control. |

Drive Belts, Chains, and Couplings |
Weekly inspection; detailed check monthly |
Inspect tension, alignment, wear, lubrication condition, loose fasteners, and abnormal vibration. Adjust or replace components according to the equipment manual. |
Isolate electrical and pneumatic energy before reaching into the drive area. Install all transmission covers before restart. |

Bearings and Lubrication Points |
Daily condition check; lubrication according to service interval |
Monitor noise, temperature, vibration, grease condition, and leakage. Apply only the specified lubricant and avoid over-lubrication that may contaminate products or damage seals. |
Keep hands away from moving parts during condition checks. Clean spills promptly to prevent slips and product contamination. |

Conveyor, Feed Table, and Product Guides |
Daily cleaning and inspection; alignment check weekly |
Remove product residue, inspect belts and rollers, check guide alignment, and verify that feed components move smoothly without trapping or crushing hazards. |
Use isolation procedures before cleaning near nip points. Keep loose clothing, jewelry, and hands away from in-running areas. |

Electrical Controls and Sensors |
Visual check each shift; preventive test quarterly |
Inspect cables, connectors, control panels, proximity sensors, limit switches, and sensor alignment. Check for moisture, heat damage, loose terminals, or intermittent signals. |
Electrical work must be performed by a competent person. Verify isolation, discharge stored energy, and restore panel covers before energizing. |

Pneumatic and Hydraulic Systems |
Daily leak check; detailed inspection monthly |
Inspect hoses, fittings, regulators, valves, pressure readings, and cylinders. Check for leaks, damaged tubing, unstable pressure, and unexpected movement. |
Release pneumatic or hydraulic pressure before servicing. Support raised or suspended components mechanically; do not rely on fluid pressure alone. |

Cleaning, Sanitation, and Corrosion Control |
After each production cycle; deep inspection weekly |
Clean food-contact and non-product-contact surfaces using approved procedures. Dry exposed metal surfaces, inspect welds and joints, and remove corrosion before it affects hygiene or structural integrity. |
Disconnect and isolate the machine before wet cleaning. Protect electrical components and follow chemical handling and personal protective equipment requirements. |

Performance, Calibration, and Safety Review |
Performance review monthly; full preventive review quarterly |
Review cut thickness, product yield, vibration, noise, downtime, repeat failures, and safety incidents. Verify measuring devices and update the preventive maintenance schedule based on operating history. |
Confirm that corrective actions are closed before returning equipment to normal production. Conduct refresher training when procedures or hazards change. |
