ADJUSTING THE TIGHTNESS OF SETTING, CHANGING DIES
Machine model PG-239 can set grommets in different types of material of different thicknesses. For
a perfect grommeting action you can adjust the pressure that the dies put on the grommets. Each time
the dies are changed, or a different material is used, it may be necessary to adjust the machine so that
a proper setting is achieved.
Machine model PG-239 has two vertical axles:
- Nº 230 “Driving stem” that governs the cutting pressure, and,
- Nº 215CA “Plunger” that governs the pressure of the grommeting.
If you want to change the whole set of dies, you must follow the instructions from number 4 to
number 7 shown at point 4.1.Change of grommet model; page 11. You must always change the dies
with the machine disconnected from power source.
With the machine unplugged.
CUTTING PRESSURE:
- Remove the flywheel cover part nº 158A
- Manually rotate flywheel nº 274 (clockwise) until top set spindle nº 218, is in its lowest point
- Unscrew nut that holds the bottom die in place, then rotate the bottom die holder part nº 220
until the bottom die part nº 219 barely touches the top set spindle part nº 218. Secure the bottom die
holder part nº 220 through nut. The pressure of the spindle nº 218 against the bottom die nº 219
must be minimum, the pressure which is sufficient for punching a hole on a piece of paper.
PRESSURE OF THE GROMMETING:
- By unscrewing nut part nº 216 you will be able to turn the top set nº 217 to the right or left, until
the distance between the bottom die nº 219 and the top die nº 217 equals approximately the thickness
of the material used for setting the grommets,
- Manually rotate flywheel nº 274 (clockwise) and check weather the adjustment of the dies is
correct,
- Secure the top set nº 217 through nut nº 216
- Replace the flywheel cover nº 158
SETTING GROMMETS ONLY, WITHOUT THE WASHERS
Machine model PG-239 can also place grommets without the washers.
With the machine unplugged:
- Empty the hopper box and the raceway of washers,
- On the “IMO V3” turn the washer detection switch to the “0” position.
- Adjust the pressure of the grommeting and the cutting pressure
For placing grommets without washers, we advice you to replace the bottom die #219 with another
one specific to this task.
