23. Q. How many drops should be fed per minute?

A. From one to seven, timed by the watch, depending on conditions.

Cylinders of large size require more oil than smaller ones.

24. Q. If lubricator feeds regularly when working steam and too rapidly

after shutting off, what is the trouble?

A. The opening in the choke plug at the lubricator or through the steam

valves at the steam chest is too large and should be reduced to the

proper size by applying new chokes or valves.

25. Q. When valves appear dry while using steam and the lubricator is

working all right, what would you do to relieve these conditions?

A. Ease off throttle for a few seconds to reduce the steam chest

pressure and drop the reverse lever a few notches to give the valve a

longer travel; oil held in the pipes will then flow down.
