4. Q. How should feeders of all oil cups be adjusted?

A. To feed as small a quantity of oil as possible and regularly to give

perfect lubrication.

5. Q. Why is it bad practice to keep engine oil close to boiler in warm

weather?

A. The oil is thinned to such a degree by the heat of the boiler that it

runs off as soon as applied, and very often a hot bearing is the result.

6. Q. In what manner would you care for a hot bearing if discovered on

the road?

A. Use as much time as available in cooling the same, making sure that

all moving parts are free and carefully lubricated before proceeding.
