USING MARKING GAGES
Press the head (1) firmly against the edge of the work
(2) be marked. With a wrist motion, tip the gage forward
until the spur touches the work. Push the gage along
the edge to mark the work, keeping the head firmly
against the work.
CARE OF GAGES
1.
Exercise care when using thickness gages to
measure clearance of knives and cutters on
machines. Do not lower knife on thickness blade
and then try to remove the gage. The blade may
be shaved off it if is too tight. Never use gages
for cleaning slots or holes. When blades are
damaged or worn they should be replaced.
Blades in a case are removed by loosening the
clamp and sliding out the damaged blade. Insert
new blade and tighten clamp.
2.
Always coat metal parts of all gages with a light
film of oil when not in use to prevent rust. Store
gages in separate containers. Do not pile gages
on each other. Always return blades of leaf-type
gages to case after use. Keep graduations and
markings on all gages clean and legible. Do not
drop any gate. Small scratches or nicks will result
in inaccurate measurements.
