How to properly use and maintain a gun?
To achieve the best results and maximize the life of your tool, follow these simple steps. Make sure the smooth chrome shaft is completely clean before inserting the grease. Press the rear release button on the shaft and pull it back. Insert the tube or bag of grease into the aluminum cylinder and screw on the nozzle cap. Apply even pressure to the ergonomic handle as you work.
Always clean the gun thoroughly after finishing work. Since the housing is closed and made of aluminum, cleaning is quick and easy. Remove any remaining glue with a damp cloth or a suitable cleaner before it hardens. This way, your gun will always be ready for the next project.

Frequently Asked Questions (FAQ)
1. Can I use sealants in bags (guts) with this gun or only cartridges?
Because the gun has a closed cylindrical aluminum housing, it is ideal for using both classic cartridges and materials in foil bags (guts) up to a volume of 400 ml. This allows you greater flexibility and savings when purchasing material.
2. How does stepless compression work?
Stepless pressing means that the smooth chrome-plated shaft moves continuously and smoothly, without any toothed steps. This gives you extremely precise control over the amount of material extruded, as you can adjust the pressure on the handle completely freely and without jerky movements.
3. How do I clean the aluminum casing after using grout?
We recommend cleaning the gun immediately after use, while the material is still wet. Simply unscrew the aluminum tube, remove any remaining material and rinse with warm water (if using water-based materials) or a suitable solvent (for silicones and polyurethane materials). Regular cleaning ensures smooth operation of the shaft the next time you use it.
