Injection Procedure -
1. Loosen the injector pressure rod.
2. Remove the injector from the barrel.
3. Place between 3 to 5 drops of resin into the injector barrel. *Always make sure to
use the right resin for the job. If the temperature of the work area is warm or the
job is at high altitude; always use a thicker resin. If the temperature of the work
area is cool or at sea level use a thinner resin.
4. Wet the two o-rings on the injector tip using resin.
5. Place the injector back into the injector barrel making sure that the groove on the
injector lines up with the retaining screw. Adjust the retaining screw so that the
threaded end of the screw slips into the groove and is just tight enough for the
injector to move freely up and down but not be removed from the barrel (the end
of the groove on the injector will catch the retaining screw and stop).
4. Make sure that the injector assembly and bridge adjusting screws are backed out
enough so that they do not make contact with the glass until the vacuum cup is
fully engaged on the glass. Note: If the injector assembly and bridge adjusting
screws are not backed far enough out, this could result in applying pressure and
causing further damage to the break.
Setting Up the Bridge and Injector Assembly -
1. Place the bridge and injector assembly onto the glass so that the injector tip
o-ring is over the rock chip.
2. Secure the bridge by flipping the vacuum cup lever.
3. Screw the injector assembly down until the o-ring makes contact with the surface
of the glass.
4. Screw the bridge adjusting screws down equally until the o-ring has a flat look to
its appearance. This will ensure that the o-ring is snug enough to create an air-
tight seal.
Note: Always make sure not to over-tighten the injector assembly or the bridge
adjusting screws. This could cause further damage to the break.
