Eight pages open the book, ruled into four columns: date, litres, hours, by. A generator that gets topped up by three different people over a month needs that last column, or nobody can say who actually checked the set the week it started surging.

Sixty lined pages follow for the running log itself, open rather than boxed into a table, because what is worth recording changes: hours run on one visit, oil pressure and coolant on the next, the load it was carrying the day it tripped. Twenty pages of plain notes close the working section, for a fault that took more than one visit to run down.

It will not set your service intervals, and it carries no acceptable oil pressure printed anywhere on the page. Those numbers come from the set's own manufacturer and from whoever wrote your maintenance plan, and they belong on the page in your handwriting, not pre-printed by somebody who has never seen your generator.

What is inside

Fuel log
8pp
Four columns fixed, so a set topped up by more than one person still has one traceable record.
Running log
60pp
Lined, not boxed into a table, because what is worth recording changes from one visit to the next.
Notes
20pp
Plain ruled, for a fault that took more than one visit to run down.
Reference
6pp
Fuel, weight and temperature conversions computed from definitions, plus emergency numbers cross-checked against two sources.
Last leaf
1pp
A pen-test page, printed on purpose, so a real log page does not take the hit.

In every book

The same six pages open every book: your details, who to call, the signs to point at when you have no shared language, and the map. They sit at the front because the moment you need them is not the moment to be flicking through.

How to use it
One page describing this book, not a different one.
This book belongs to
One page for your name and number, so a book that goes missing can come back.
My details
Blood group, allergies, who to call. Written once, carried everywhere.
Emergency numbers
Forty countries, taken from Wikidata property P2852 (CC0), agreed across two sources, every row carrying its QID. Numbers change and a book does not — verify locally on arrival.
Point at this
A pictogram grid captioned in English above and Indonesian below, for when there is no shared language.
World map
Natural Earth 110m, public domain, equirectangular, with UTC hour meridians computed from the projection rather than from a timezone database. For orientation and for pointing at, not a navigation chart.
Conversion tables
Computed from definitions — 25.4 mm to the inch — and not copied from anywhere, so every row can be checked by anyone holding the book.
Pen test leaf
The last page, printed for it on purpose. Every notebook is used this way; printing it deliberately is cheaper than losing the last leaf to it by accident.

The film

Page by page

A vertical film, 52 seconds: the cover, the ruling page, then 5 reference pages. Synthesised ambient bed, no dialogue — captions in three languages.

A vertical film from our own bench — this page contacts nobody's server to play it, and downloads nothing until you press play.

What is inside this book?

Five pages from the Generator Set Logbook laid out as cards: a four-column fuel log page, a section divider, a lined running log page, a conversion table, and the pen test page.
Five pages rendered straight from the print file: the four-column fuel log, a divider, a lined running-log page, the conversion tables, and the pen-test leaf at the back. Litres and hours on their own tell you the set ran. They do not tell you it ran well, which is what the lined pages behind them are for.

Questions

What are the fuel log columns?

Date, Litres, Hours, By.

How big is it?

A5, 148 x 210 mm, 100 pages, 5.72 mm across the spine.

Is it dated?

No. Start it when the set is first commissioned.

Does it print service intervals or an acceptable oil pressure?

No, and that is deliberate. Those figures come from the set's own manufacturer and from whoever wrote your maintenance plan, they differ from one generator to the next, and a printed book cannot be corrected once it is in your hands.

What ruling is the running log?

Lined, 7.14 mm pitch, 9/32 inch, twenty-four lines to the page, open rather than boxed into columns.

Who is it for?

Generator technicians and anyone else responsible for keeping a standby or prime-power set fuelled and running.

We will take one which relates to iron, for instance, as you have already seen iron burn a little in the atmosphere.
Michael Faraday, The Chemical History of a Candle, 1861
