Storage recommendations

Store the 408N gun in a dry, clean place away from moisture and aggressive chemicals. After use, remove the tube from the cradle, clean any residual material from the working parts and leave the mechanism in the rest position to avoid constant spring load. Do not store the tool outdoors or in heavily contaminated environments to maintain its anti-corrosion protection.

FAQ

1) Which tubes does the 408N Newborn gun fit?
The 408N model is designed for standard 10 oz (approx. 310 ml) cartridges with three lugs – 3-lug tubes.

2) What is the thrust ratio and what is it suitable for?
The 6:1 thrust ratio is suitable for applying silicones, acrylics and other medium-viscosity materials in typical finishing and installation work.

3) Is the gun suitable for intensive daily use?
Thanks to its lightweight construction and zinc chromate plating, the 408N performs well in frequent service work; for very high-viscosity materials a higher thrust ratio may be more comfortable.

4) Does the gun require special maintenance?
After use, simply remove residue and store the tool in a dry place; no complex maintenance is needed, although regular cleaning will extend the life of the mechanism.

5) Will the 408N work with standard smooth-rim cartridges?
No, the cradle is designed specifically for 3-lug tubes, so you should check the type of cartridges you use before purchasing.
