INTRODUCTION PNEUMATIC MACHINE MODEL PG-21 FOR PLACING APPLICATIONS BY HAND The function of this machine is the placement of applications or to punch holes (maximum interior diameter of tube grommet 14mm) in materials that need these applications. Specially recommended for placing grommets and washers in: awnings, curtains, advertising signs, etc. WARNINGS! We hope you will take notice of these warnings and we would like to thank you for the purchase of this machine.
1. DESCRIPTION OF THE MACHINE AND ITS OPERATION. (See figure below) The machine consists of the head, air hoses and pneumatic foot pedal. The moving parts in the machine are located inside the head (pneumatic cylinder, manometer, axles, dies, etc.). After placing the machine in its permanent location, without fitting the air hosepipe into the mouth of the compressor, verify that it has not suffered any blow or breakage while being transported and that it has not any loose parts.
Technical Data: HEAD MEASUREMENTS: DEPTH: 30 cm WIDTH: 11’5 cm HEIGHT: 38 cm WEIGHT (with pneumatic pedal): 14 Kg Installation: The operator can work in a seated or a standing position, depending on the height of the machine. The minimum space recommended must be sufficient to keep the safety space in all directions for the operator to work properly. The buyer of the machine usually places the machine on a table. The machine model PG-21 needs at least 6 atmospheres of pressure from the air compressor.
BEFORE STARTING THE MACHINE, READ THESE WARNINGS CAREFULLY. The following are a series of instructions and warnings which must be taken into account with regard to the model PG-21. - Before connecting the machine to the compressor, it should be placed in its permanent location. Do not connect any electrical devices to the machine before it has been placed in its permanent location.
Machine Description Maximum interior diameter of grommet and washer is 12mm. The machine perforates and sets the grommet with the washer at the same time. Each set of dies sets only one grommet and washer model; the grommet models may differ in: the head size “B”, the length “C”, the interior diameter of tube “A”, the thickness, etc; and the washer models may differ in: the exterior diameter “B”, the length , the interior diameter of washer hole “A”, the washer shape, etc.
SETTING UP THE MACHINE FOR ITS OPERATION Before starting the machine for the first time, and each time the location of the machine is changed, or any changes are made in parts or any adjustments are done to it, we recommend the following steps: After placing and making the machine level in its permanent location “STILL WITHOUT PLUGGING IT IN”, lubricate it with SAE 40 type oil in the grease cups and red marks.
For the following procedures, refer to the diagram on page 11 CHANGE OF DIES FOR THE SAME GROMMET AND / OR WASHER SIZE Changing the bottom die #19: With the machine disconnected from the compressor (and from the power source if it has any electrical devices).
For adjusting the cutting pressure (the cutting pressure punches a hole in the material), you have to turn the bottom die # 219 to the right or to the left, so that when you start the machine and press the foot pedal, the top set spindle # 218 barely touches the bottom die # 219. With the machine disconnected from the compressor (and from the power source if it has any electrical devices).
RING GUARD ADJUSTMENTS Whenever the machine is adjusted or modified or some parts are changed it is necessary to adjust the safety device again (pneumatic safety cylinder # 265, end of race # 267, ring guard # 306, etc) so that it may work properly. - Connect the machine to the compressor and open the air inlet # 260, - The safety manometer # 8 must indicate 1 kg by means of the safety control # 7, - Shut the air inlet # 260 and disconnect the machine from the air compressor.
238 217 219 194 306 230 260 Recommended pressure is 87-90 psi. Input regulator must be used with the PG-21.
MAINTENANCE MECHANICAL PART OF THE MACHINE For an optimal operation of the machine, it is recommended that you keep some parts clean and always lubricated. The cleaning should ALWAYS be done with the machine disconnected from the electrical power source and the compressor. The pedal we press to operate the machine, should always be clean and clear of any debris that could prevent it’s normal operation.
TROUBLESHOOTING PROBLEM THE MACHINE DOES NOT OPERATE WHEN PRESSING THE FOOT PEDAL. DEFECTIVE GROMMETING. IT WILL NOT CUT OR LEAVE MATERIAL RESIDUALS. THE RING GUARD COMES DOWN, BUT THE DIE DOES NOT. CAUSE SOLUTION Make sure the air inlet is connected to the compressor. Make sure the air inlet is in the open position. Make sure the correct air pressure is supplied The bottom die is worn out or broken. Incorrect tightness of setting. Incorrect adjustment of pneumatic pressure.
