Most combination breaks do not need to be drilled. They usually have a larger impact and crushed glass in the middle of the damage. They typically have a good entrance and many path ways for the resin to flow into.
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.
Add 5 drops of chip resin and perform pressure and vacuum cycles. This
pressure pushes the resin into the bulls-eye and the vacuum pulls the air out.
Quick pressure and vacuum cycles work the best lasting about 30 seconds each.
These cycles are explained in more detail below in the graphic.
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 combination
break 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 repair
immediately slide tool back onto the combination break repair and continue to cure
for another 5 minutes.
Pit fill the repair with pit filler, crack resin or if you
bought a basic kit use chip resin.
