Lesson 4/Learning Event
Care of Gages
a. Exercise care when using thickness gages to measure clearance of
knives and cutters on machines. Do not lower a knife on a thickness
blade and then try to remove the gage since the blade may be shaved
off if it is too tight.
b. Never use gages for cleaning slots or holes.
c. When blades are damaged or worn, replace them.
d. Blades in cases are removed by loosening the clamp and sliding out
the damaged blade. Install a new blade and tighten the clamp.
e. To prevent rust when storing gages, always coat the metal parts with
a light film of oil.
f. Store gages in separate containers.
g. Do not stack or pile gages.
h. Always return blades of leaf-type gages to their cases after use.
i. Keep graduations and markings on gages clean and legible.
j. Do not drop gages.
