1. Thou shalt keep thine engine clean and in adjustment that thy life in its compay shall be long and that thy owner shall increase thy pay.
2. Know thine engine and all its parts and functions else thou shall be in some unholy spot.
3. Be not wise in thine own conceit. Remember the factory instructions and keep them holy, lest repairs be thy undoing.
4. Be not loose in thy jaw hinges for no man knoweth all about Diesels. The truly wise absorbeth much knowledge and exudeth little, and he who so doeth shall gain repute among his fellows and favours among his superiors.
5. For all things in this life thou desireth thou shalt also pay plenty; for the wisdom of experience no less. Advice from the multitudes costeth nothing and is usually worth Just that.
6. In the book thou mayst read what to do and when, but only the voice of experience may tell thee why and how, else thy reading of what and
when shall but plague thee with smoke.
7. God maketh the earth to rotate endlessly without bearings or oil, but not thy Diesel.
8. Curse not thine engine when it turneth not. Curse rather thine own stupidity.
9. Steam engines and gas engines may long turn over though sloppy; A Diesel not so with gauges and micrometers be thou ever busy.
10. The eternal eye watcheth universal operations, but thou shalt not rely upon it as to thy Diesel. Thine own rigilance is the price thou payest for thy job.
