The machine model PG-21 can be adjusted for placing grommets with washers in
different types of material and in different thicknesses.
Machine model PG-21 has two vertical axles:
# 121 the driving stem that adjusts the cutting pressure (to punch a hole in the material), and
# 122 the top set spindle that adjusts the pressure of the grommeting.
CAUTION: For adjusting the pressure of the machine, it will be necessary to connect the air
hosepipe to the compressor and open the air inlet handle #260. Please be very careful while
doing these adjustments, always making sure that your hands and fingers are out of the
grommeting area and that nobody can press the foot pedal, which would cause the top set to
come down and catch a hand or finger.
