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. Loosen the screw for holding ring # 278 with the 3 mm allen wrench,

-Place the ring guard # 306 at about 6 mm from the bottom die # 219.

This adjustment can be done (with the air inlet # 260 in the shut position and the machine disconnected from the compressor) by putting one side of the 4 mm allen wrench (it is supplied together with the machine) on top of the bottom die # 219, you lower the ring guard

# 306 until it touches the side of the 4 mm allen wrench.

-Tighten the screw for holding ring # 278 with the 3 mm allen wrench (it is supplied together with the machine).

Before connecting the machine to the compressor, verify that all the parts are tightened up.

CHANGE OF DIES FOR ANOTHER GROMMET AND/OR WASHER SIZE

The machine model PG-21 can place two different sizes of grommets and washers. 8mm and 12mm.

If you wish to set a new grommet and washer size, you will have to replace some parts of the machine.

-The new set of dies for the new size,

-Adaptors for the new size. These adaptors are not always the same and vary according to the grommet and washer sizes.

In order to avoid any problems, Sinclair Equipment recommends that whenever you ask for a new set of dies for a new grommet and washer size, please show us the following references:

-The reference of the machine,

-The reference of the grommet and washer models that the machine is setting,

-The reference of the new grommet with washer model that you want to place.

With this information, we can show you the parts you must replace.

The ring guard # 306 varies in size according to the grommets and washers size.

The changes of dies and parts, the pressure adjustments, the possible breakdowns, etc, are the same that are shown in this manual.

REMEMBER THAT AFTER CHANGING DIES, YOU MUST ALWAYS ADJUST THE CUTTING AND THE GROMMETING PRESSURE AND ALSO THE RING GUARD.
