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.

The operation of the machine is very simple:
When pressing the pedal “C” a pneumatic safety cylinder “B” is activated. The safety

cylinder causes the ring guard “E” to descend right to the point where it can check
that there are not any fingers or hands in the grommeting area “D” and activates the
micro end of race which sets the pneumatic cylinder “A” in motion.
The pneumatic cylinder “A” causes the vertical axles to descend. Attached to the
lower part of the vertical axles are the top set spindle and the top die that does the
grommeting.
The aim of the downward movement of the axles is to cause the top-set spindle to
punch out a hole in the material and to set the grommet situated in the grommeting
area “D”, by means of the pressure that the top-die puts on the bottom die.

After this cycle the machine returns to its starting position ready for a new
application as soon as you place the grommet and the washer and press the pedal
“C”.

machine usually places the machine on a table.

The machine model PG-21 needs at least 6 atmospheres of pressure from
the air compressor.

WARNING: FOR BETTER OPERATION THE COMPRESSOR HOSE PIPE

SHOULD NOT BE COMPLETELY STRETCHED.

The transportation of this machine requires a series of operations.
Some of these operations may imply dangerous situations so please follow the
following advise:

- Never stand beneath the cargo.

- Always lift the cargo gently.

- Avoid balancing the cargo.

- No brisk movements.

- Do not place yourself in the cargo moving trajectory.

- Use the correct equipment to move cargos.

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.

- Cleaning, manipulation and replacement of parts of the machine must always be carried
out with the machine disconnected from the mains power supply.

- Do not remove from the machine any parts which protect the user from possible
accidents, or adhesive labels or signs indicating electrical or hazardous components.

- The machine has an air inlet handle which is used to let the air into the machine. When
the machine is not in use, it should be shut in order to avoid any accidents in case of
manipulation by third persons. We also recommend you disconnect the air hosepipe from
the compressor for safety reasons.

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.

SINCLAIR EQUIPMENT RECOMMENDS YOU TO USE ALWAYS THE SAME TYPE
OF GROMMET AND WASHER FOR WHICH THE MACHINE WAS DESIGNED. In
order for the machine to set different grommet and washer models, certain parts need to be
changed.

Sinclair Equipment will accept no responsibility arising from the use of this machine in any
way different from that which is described in this instruction manual.

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. Let
the oil have enough time to cover the parts and then clean the excess oil that might remain or
drip.

To verify the machine is not blocked or might have suffered a blow or breakage:

1- Remove the top cover,
2- Verify the machine is not blocked or that it has any loose parts.
3- Put the cover back and fasten the 4 allen screws.
4- Lubricate the parts as indicated.

ADJUSTMENTS

DISCONNECT THE MACHINE TO CHANGE THE DIES, ADJUST THE
PRESSURE, ETC

For an optimal operation, the machine has to be adjusted for each type of material and
grommet, keeping the parts that do the grommeting (dies and spindle) in good condition.

The bottom and top dies #219 and #217, and the top set spindle #218 are the parts that need
to be replaced regularly due to the normal use of the machine. You will realize that they have
to be replaced when the machine does not cut cleanly and / or the grommeting is defective.
We recommend you always have spare dies.

If you have to remove any part meant for the safety of the operator in order to do these
adjustments (for example: acrylic cover, ring guard), remember to put them back where they
belong.
