Screw suction cups on to Crack Easer tool. The suctions cups go on the non ribbed side of the tool where you see word Crack Eraser.  Lube suction cups with lubricant.

To mount the crack eraser tool set the tool with the bigger threaded part over the chip you are going to repair. It usually works better if you mount the tool above or below the repair not to the side of it unless the chip is close to the edge then mount to the side. Push firmly down on all three suction cups until you do not here a squishing sound. It is important you push hard enough to get all the air out the suction cups or the tool may pop off during the repair.

Install Injector 0-ring on the piston and push into the injector do not tread in yet. Next tread injector into the crack eraser tool. Then tread adjusting bolt into crack eraser tool.

Adjust the injector and adjusting bolt by turning each of the in until they touch the windshield the turn 3 turns more on both the injector and the adjusting bolt. You want the Crack Eraser tool to be level with some pressure on the injector so you can keep a seal while injecting. 

It is very important that you cure the repair under pressure in the sun or with a cure lamp for at least 10 to 15 minutes after the injecting process. This lets the UV reflect in a start the resin curing process. If the tool is removed to soon air may creep back into the bulls-eye repair before it has time to fully cure. Curing under pressure prevents this from happening. It is fine to slide the tool away and look to see how the repair is filling, but only look for less than 10 seconds and the slide the tool back on and continue to cure. You do not want direct sunlight or UV until you are sure the air will not creep back in. The mirror helps the curing under pressure by reducing the time and aids in being able to see the repair filling with out sliding the tool away to look at the progress. If you slide the tool away and you see the air which will show up black coming back into the bulls-eye repair immediately slide tool back onto bulls-eye and continue to cure for another 5 minutes.

Remove the Crack Eraser tool and scrape the excess resin with a razor blade. The graphic below will explain this procedure in more detail.
