MODEL 250P AUTOMATIC NUMBERING HEAD
for 1/4” – 3/8” Characters
Operating Instructions
1. DO NOT DROP OR ABUSE THE MODEL 250P. The Model 250P is a
precision machine; carelessness could damage the pawls or springs.
2. When inserting the Model 250P into the press, make sure the numbering
head frame bears the load. The shank aids only to hold the head in the press.
Stress should not be applied to the shank.
THE MODEL 250P SHOULD
NEVER BE HAMMERED OUT OF THE PRESS
.
3. The actuating arms (50-3-2) should be facing towards the operator for right
side up stamping.
4. The wheels in the Model 250P can rotate in only one direction, away from the
actuating pawl (50-3-10). Damage to the actuating or retaining pawls can
occur if the wheels are forced in the wrong direction.
5. Never attempt to stamp on a surface, unless it is perpendicular along both
axes to the Model 250P printing plane. Damage to the actuating or retaining
pawls can occur if this warning is not heeded.
6. Make sure that each number wheel is completely indented before stamping. If
the wheels are indented properly, they should snap or click back into the
indent position after being rotated slightly beyond that position. Stamping with
the wheels between indents can damage the actuating or retaining pawls.
7. When adjusting the tripping mechanism, make sure the wheels do not begin
to rotate while they are still in contact with the work. In addition to moving the
work, rotating the wheels could damage the actuating pawl.
8. When adjusting the tripping mechanism, make sure the actuating arm does
not bottom-out on the actuating stop pins. It is possible to shear these pins,
possibly damaging the numbering head.
Marking Instructions
These instructions assume the operator is facing the front side of a press-
mounted Model 250P Numbering Head. The actuating pawl (50-3-10) is on the
front side. The following procedure adjusts the numbering head to stamp
consecutive numbers beginning with the number one.
