Sinclair Electronic Automatic Grommet PG-239, Operating Manual

MACHINE DESCRIPTION 

The PG-239 model is an automatic electronic machine designed to set grommets with washers, 
grommets without washers or to make holes in the material. 
 
Each machine is manufactured for a specific size of grommet and washer. 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 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 (the raceway 
and the top and bottom sets); but you always have to use the same washer the machine was 
manufactured for. 
 
In order for the machine to set different grommet models, certain parts need to be changed.

SINCLAIR EQUIPMENT will accept no responsibility arising from the use of this machine in any

SETTING UP THE MACHINE FOR ITS OPERATION

PLEASE VERIFY THESE ADJUSTMENTS BEFORE CONNECTING THE MACHINE. 

 
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. 
 
 
1- Remove the cap nº 158 “pulley cover” that covers the flywheel by loosening the 4 allen screws 
that tighten it. 
2- Rotate the flywheel nº 274 manually one cicle of 360º in the direction that the red arrow points 
(clockwise). 
3- Verify that the machine is moving freely. 
4- Put the cap on again (nº 158) and tighten it with the 4 allen screws.
