Data notes

‖

Converted metric figure. The source published imperial figures only for this machine. Metric figures marked ‖ are unit conversions of the published imperial value, rounded to the same precision — they are not separately published measurements. Because there is no independently published metric figure to compare against, no cross-unit consistency check applies to them; the imperial figures they derive from were checked for physically possible magnitude and for plausibility against this equipment class.

Method. Figures are manufacturer reference specifications, not measurements. The source published imperial figures for this machine in a single unit system, so no cross-unit consistency check applies; every value is checked for physically possible magnitude and for plausibility against its equipment class before publication. Figures that fail either check are withheld rather than shown, and figures reconstructed from related data are marked above. Metric figures marked ‖ are converted from the published imperial value rather than reproduced from the source.
