Guides from the manufacturer's own manual — the fault codes, the intervals, and what nobody on the floor should touch. Each one opens in its own tab and prints from there. Nothing here was invented, and every sheet says where its figures came from.

Every task you ticked “use this to build an SOP” on, gathered with everything that was written while it was worked. This is the raw material for a standard procedure — so writing one is editing rather than remembering.

What actually happened, on our machines, with the dates and the measurements kept. No manual contains one of these — which is the whole reason they are worth writing down. The second oven repeated the first one's fault from scratch because nobody had written the first one down.
