Weekly PM Checklist

This checklist is built for the weekly cadence specifically — mechanical and safety items that move too slowly for a daily look and too fast to wait for the monthly cycle. Running it on a different schedule, or substituting it for a different checklist's scope, breaks the PM compliance trail.

The checklist is built against ISO 55001 cl.8.2, the same operational-control clause underpinning the rest of the PM checklist family, applied here to the slower-cycle mechanical and safety items a weekly cadence covers.

ISO 55001 provides the operational-control frame, but the safety-device items on this checklist sit directly on top of statutory machinery and work-equipment law wherever the asset actually runs.

The mechanical answers are usually straightforward. The judgement calls sit in how a marginal condition gets scored and how quickly a safety-device Fail gets converted into a tracked job.

These are the gaps that show up repeatedly once a site has been running this checklist for a few months, each with a specific fix rather than a general reminder.

A boning hall conveyor's guard interlock was marked Pass on six consecutive weekly checklists. Nobody had actually opened the guard to trigger the interlock during any of those checks — the technician was confirming the guard was closed, not that opening it stopped the machine.

An operator reached past the guard during a jam clearance and the machine kept running. The interlock had failed weeks earlier; the checklist had recorded a visual confirmation as a functional one, which is exactly the gap a required Pass-confirmation note on safety devices closes.

The check itself is a fixed set of questions. Catching a Partial that never converts to a Fail, or a Corrective Work Order ID left blank, needs something watching the pattern across weeks, not just the single record.

KnowMaintain

Holds the weekly checklist against the Asset register and PM Plan, escalates a Partial repeated on the same item to a required finding, and keeps corrective work orders linked back to the check that raised them.

KnowSafe

Rolls Element Tag findings from Safety devices into the same hazard view used across guarding, PPE and isolation templates, surfacing a recurring interlock or guard issue before it becomes an incident.

KnowQuality

Tracks Completeness Percent alongside Score Percent across the fleet, flagging sites where safety-device items are being answered without a genuine functional test.

Ella

Coordinates the technician's weekly round, surfaces open corrective work and repeated Partials in one view for the shift lead, and holds every write for approval before it touches a record.

Function-tested

Verified by actually operating the device — triggering an interlock, pressing an emergency stop — rather than confirmed only by visual inspection.

Knockout item

A field whose Fail answer overrides the rest of the checklist and drives the asset's fitness result, regardless of other scores.

Corrective work order

A separate, trackable job record raised from a checklist finding that needs parts, isolation or scheduled downtime to resolve.

Element Tag

A hazard-type label applied to a Fail finding so it can be aggregated with matching findings from other checklists and templates.

Equipment Fit For Service, with restrictions

A conditional fitness result meaning the asset can keep running only under a named limitation, which should be traceable to a linked corrective record.
