Cashew Processing Equipment Maintenance and Downtime Log: A Practical Factory Toolkit

A cashew-processing business depends on more than the quality of its raw nuts. When a shelling machine stops, a dryer needs attention or a packing machine develops a fault, production may slow down, workers may have to wait and orders may be delayed. If these incidents are handled only through verbal messages, the same problems can return without a clear record of what was done.

The Mato Cashew Equipment Maintenance and Downtime Log is an editable recordkeeping toolkit for small and growing cashew processors. It helps teams organize equipment information, document work performed, record unplanned stoppages and follow up on outstanding issues. It is an operations management tool, not a machine-repair manual, food-safety certification or legal-compliance checklist.

Who can use this resource?

This toolkit is intended for cashew-processing enterprises, cooperatives, workshop supervisors, maintenance personnel, production managers and researchers collecting operational information. It can be adapted for shelling machines, steam equipment, dryers, peeling machines, grading equipment, packing machines and other equipment used at a processing site.

Small businesses may begin with only a few machines. The important point is to keep a consistent record rather than create a complicated system that nobody updates.

What is included in the Excel workbook?

The workbook contains blank entry rows and automatic calculations for the next scheduled service date, completed downtime hours and selected dashboard indicators. The service interval is not preset: each business must determine it using the equipment manufacturer’s instructions, operating conditions and its own risk assessment.

1. Give every machine a unique equipment ID

Start with the Equipment Register. Assign each machine a simple identifier, such as SH-01 for a shelling machine or DR-01 for a dryer. Record its name, location, make or model where available, responsible person and the location of its operating or service instructions.

A consistent equipment ID allows the same machine to be identified in the maintenance and downtime logs. It is especially useful when a factory has several similar machines.

2. Record planned inspections and completed maintenance

For each inspection, planned service or repair, enter the date, equipment ID, work-order reference, observed problem, work completed, person responsible and any further action required. When relevant, record whether appropriate energy isolation and return-to-service or hygiene checks were verified by authorized personnel.

Do not mark an action as closed merely because a part was replaced. The responsible person should confirm that the machine has been safely released for use under the site’s approved procedures and that any product-contact or surrounding area has been checked as necessary.

3. Measure downtime consistently

When a machine stops unexpectedly, enter the full start date and time and end date and time, together with the affected equipment and a short explanation. The workbook calculates:

Downtime (hours) = (end date/time − start date/time) × 24

For example, a hypothetical stoppage from 09:10 to 10:25 on the same day is 75 minutes, or 1.25 hours. Record the suspected cause separately from the confirmed cause if the investigation is still open. If the machine has not restarted, leave the end timestamp blank and keep the incident open rather than entering an estimated duration as a completed result.

Downtime hours show the duration of logged interruptions. They do not, by themselves, establish equipment availability or productivity. Calculating availability also requires reliable records of planned operating time and the applicable definition of downtime.

4. Review outstanding work every week

A short weekly review can help managers identify which machines repeatedly stop, which service dates are overdue, and whether repairs remain unresolved. Assign an owner and a due date for each important action. Review recurring problems with the people operating and maintaining the equipment, and keep evidence of completed work where practical.

The Dashboard summarizes entries in the workbook, but a zero may mean no information has been entered, not necessarily that a machine has had no problems. Managers should confirm that records are complete before relying on the figures.

5. Keep maintenance records separate from other business records

This toolkit has a different purpose from Mato Cashew’s existing resources:

• The Batch Costing and Pricing Worksheet estimates costs, selling prices and potential batch results.
• The Lot Traceability and Movement Register follows cashew lots through handling, processing and delivery.
• The Supplier Onboarding and Evaluation Checklist supports supplier selection and review.

The Equipment Maintenance and Downtime Log focuses on machine condition, service history, interruptions and corrective-action ownership. A business may refer to the same production date or batch ID across these records, but the tools should not be confused with one another.

Begin by completing the Equipment Register, then use the Maintenance Log and Downtime Log as events occur. Review the Dashboard regularly. Keep a controlled master copy, protect sensitive operational information and make backups appropriate to your business.

Important safety and use notes

This workbook does not tell users how to repair, dismantle or test machinery. Maintenance on electrical, mechanical, thermal, steam or pressurized equipment can be hazardous. Use trained and authorized personnel, manufacturer-approved instructions, appropriate control of hazardous energy and the workplace’s applicable safety and food-hygiene procedures. Never bypass machine guards or treat a completed spreadsheet entry as proof that equipment is safe to restart.

Inspection frequency, training, required records and legal duties vary by equipment and jurisdiction. Adapt this toolkit to the actual factory and applicable Cambodian requirements. The external references below explain general equipment inspection and hazardous-energy principles; they are not presented as Cambodian legal requirements.
