Notes:
1. Weight is transcribed exactly as printed in the factory manual. The imperial and metric figures do not correspond (17,960 lbs. converts to approximately 8,147 kg; 7,665.8 kg converts to approximately 16,900 lbs.) — this inconsistency appears in the source document itself.
2. Displacement transcribed as printed. 256 cu. in. converts to approximately 4,195 cc (4.2 L); the source's 4,195.9 cc figure differs trivially from the direct conversion.
3. The factory manual gives thumb pressure in kilograms only; 11.3 kg is approximately 25 lbs. (editorial conversion).
4. The manual includes a graphical SAE grade selection chart (SAE 10W, 10W-30, 15W-40, and 30) keyed to outdoor temperature ranges anchored at -13°F (-25°C), 14°F (-10°C), 32°F (0°C), and 90°F (32°C). See the operator's manual for the full chart and diesel fuel sulfur-content provisions.
5. Printed as "Fired Tread" in the source; corrected here to "Fixed Tread" (editorial correction of an apparent typesetting error).
