Preventive maintenance guide

Packing machine maintenance checklist: keep routine care documented and safe.

Use this as a planning framework for routine inspection, cleaning and maintenance records. It does not replace the machine-specific manual, safety instructions, service schedule or your plant's lockout and authorization procedure.

PlanFollow manual & service history

Safety note: before opening guards, reaching into moving areas, cleaning near moving/sealing parts or carrying out maintenance, follow the machine manual and your site's energy-isolation / lockout procedure. Electrical and pneumatic work should be handled by authorized qualified personnel.

Routine operator checks

Before production: confirm the machine is ready for safe operation.

Confirm the work area is clean, dry and free from loose tools, scrap film or spilled product.

Visually check guards, covers, doors and accessible safety devices for obvious damage or missing parts.

Check visible power cables, plugs, air tubing and fittings for damage or obvious leakage; escalate defects instead of improvising a repair.

Confirm the product path, hopper / filler area and film path are clean and free from leftover material from the previous run.

Verify the correct product, pouch material and approved machine recipe / settings for the planned job.

Record any abnormal condition before starting so it can be tracked instead of becoming an undocumented production issue.

After production / changeover

Clean and document before the next run.

Remove product residue and loose film using the approved cleaning method for the machine and product.

Clean product-contact parts according to the hygiene procedure and machine instructions.

Clean sealing-area residue only after the machine is safely stopped, isolated and at a safe condition specified by the manual.

Check for damaged film guides, worn-looking surfaces, loose visible hardware or residue that could affect the next run.

Record alarms, stoppages, sealing issues, filling issues and adjustments made during the shift.

Scheduled preventive maintenance

Set frequency from the manual, operating hours and service history.

Inspect belts, chains, bearings, guides and other wear items that are listed in the machine maintenance schedule.

Inspect pneumatic tubing, fittings and actuators for leakage or damage where applicable.

Inspect sensors, cables, connectors and electrical components only within the authorized maintenance scope.

Check sealing components, cutting parts and forming parts for wear or damage according to the machine manual.

Lubricate only the specified points, with the specified lubricant and interval; do not add an arbitrary lubrication schedule.

Replace wear parts and adjust alignment / tension only to the manufacturer's procedure or by qualified service personnel.

Maintenance record

Keep enough history to diagnose repeated problems.

A maintenance log makes recurring faults easier to identify and gives a service technician useful context before a visit.

Machine model / serial or internal machine ID

Date and operating-hours reference if available

Inspection finding, alarm or production symptom

Work performed and settings / parts changed

Person who performed or approved the work

Next check, service due date or unresolved follow-up

Service escalation

Do not keep running through a condition that needs technical attention.

Safety / electrical

Damaged guarding, safety-device faults, damaged wiring, overheating or a burning smell.

Mechanical / pneumatic

Severe abnormal noise or vibration, persistent leakage, damaged moving parts or repeated jams.

Process / control

Repeated alarms, unstable filling or sealing that remains after approved operator checks, or faults that return after reset.

Direct answers

Common packing-machine maintenance questions.

How often should a packing machine be serviced?

There is no universal interval for every packing machine. Use the machine-specific manual, operating hours, product, environment and service history to set the preventive-maintenance schedule. S.K. Packaging can confirm AMC or service scope separately for the selected machine.

Can operators carry out all maintenance tasks?

No. Operators can perform approved routine cleaning and visual checks within their training and site procedure. Electrical, pneumatic, guarded or adjustment work should be handled only by authorized and qualified personnel after the machine is safely isolated.

What should be recorded in a maintenance log?

Record the machine identity, date, operating-hours reference if available, symptom or inspection finding, work performed, parts changed, person responsible and the next follow-up or due date.

When should I call for service instead of continuing production?

Stop and escalate according to the site procedure when there is a safety-device problem, damaged wiring or guarding, burning smell, severe abnormal noise or vibration, persistent air leaks, repeated alarms, or a fault that cannot be cleared by an approved operator check.
