How to adjust the setting pressure on an eyelet or grommet machine

The setting pressure on an eyelet or grommet machine can be set in a few ways depending on the style of the machine. On a simple kick press or bench top machine there is usually a stop pin with an adjusting screw and nut that limits the stroke of the foot pedal or arm. (Go to our "How To" page for the ARP bench top eyeleter). By adjusting this screw you will only be able to pull the arm or kick the pedal to a measured distance thus regulating the amount of setting pressure.

If your machine is a power machine ALWAYS TURN OFF THE POWER before adjusting the setting pressure. On stand alone machine such as the Stimpson 489 eyeleter, the bottom die can be raised or lowered to adjust the setting pressure. The higher the bottom die is raised, the more the setting pressure is increased. Lowering the bottom die lowers the setting pressure. Most stand alone machines have a lock screw that hold the bottom die in place. You must first loosen this screw or allen screw to adjust the die up or down. Loosen the locking nut on the bottom adjusting screw. Now raise or lower the bottom die by turning the bottom adjusting screw clockwise or counterclockwise. Turn this screw 1/2 turn and check the setting. IF YOUR MACHINE IS ELECTRIC POWERED DO NOT CHECK THE SETTING PRESSURE UNDER POWER. ALWAYS TURN THE MACHINE OVER BY HAND. When you achieve the proper setting pressure tighten the locknut on the adjusting screw and then tighten the locking screw to hold the die in the machine.
