Levers and release devices

levers:

Levers that are attached to sleeves that ride on shafts should not be oiled : particularly those levers that depend on gravity to operate. The reason for this is that when the oil thickens up slightly the lever will not drop every time; or it will drop too slowly . A classic example is the count arm, or the rack as it is sometimes called. It will work just fine at first: then after several months the oil will thicken and the common complaint is: the clock only strikes 1 sometimes. If you feel you must oil the lever ; be sure that it is only the thinnest possible film; and .at that, you will be taking a chance. The more oil the more the chance of a problem.
