1. 2.1. Slowly screw plunger -6-  into the injector -5-  until resistance is felt and the shape of the seal changes → Seal under pressure  . Keep a firm hold on the injector barrel while doing this.
2. 2.2. Leave the plunger pressed down in this position for around 5 min., in which time the plunger will automatically build up pressure.

1. 3.1. Use one hand to lift the plunger -6-  (-A-  ) and secure in position by turning 90° clockwise -B-  . This allows any air to escape out of the area of damage.
2. 3.2. Release plunger so that pressure is able to build up again.
3. 3.3. Repeat steps →  3.1 and →  3.2 about 5-10 times until there is no more air in the chipped area.

If the damage is more severe, the removal of trapped air can be speeded up by warming gently. To do this, use a lighter to heat the area of damage from the inside for 3-5 seconds.

Please note:  Heat during the vacuum phase only, otherwise the expanding air would cause excessive pressure in the damaged area.

1. 5.1. Release the plunger a little (do not create a vacuum) and unscrew the injector.
2. 5.2. Remove bridge from the windscreen.

1. 6.1. Add a drop of finishing resin directly onto the impact point.
2. 6.2. Slide film across the windscreen.

1. 7.1. Place a UV lamp over the area of damage from the outside and switch on. → Curing under a UV lamp 
2. 7.2. Curing takes around 10 minutes, depending on the size of the stone chip.

1. 8.1. Remove film and scrape off excess resin using a razor blade held at a 90 degree angle to the windscreen. → Scraping off resin 

   Please note:  Risk of damage to the windscreen. Only use razor blades that are in perfect condition, otherwise they could damage the windscreen.

2. 8.2. If there is still an indentation at the point of repair, steps →  6., →  7 and →  8.1 will need to be repeated to obtain a perfect finish.

Polish the repair with polish and a soft cloth.

Please note:  Do not polish for too long as this can wear down the repair resin and the surface will no longer be flat.

After completing the repair, clean tools using a dry, lint-free cloth. The resin will otherwise perish the seals.
