With your finger, move the Pawl so that the flipper is fully plunged.
The insulated arm of the Pawl will now need to open the EOS Switch.
When fully extended, the EOS Switch gap needs to be EXACTLY 1/8". Not more, not less.
A larger than 1/8" gap will make the flipper weak, by shutting off the high power winding of the coil too soon.
A smaller than 1/8" gap risks that the switch may just arc and not shut off the high power winding at all. This overheats the coil, and burns out the associated transistors.
You will need to play with the adjustment tool and bend the switch leaves a few times to get it perfect.
If ever you find a weak flipper that otherwise freely moves through it's range of motion manually, suspect the EOS Switch. The contacts may be dirty, or the tension/gap is set incorrectly.
Now, with your Nylon Coil Sleeves, your flippers will perform better than they did when they came from the factory.
