Why is it important to check the length of brushes and the end of an air nozzle during installation?

To preserve the tools
To ensure they can reach the deepest part of the hole
To check for damage
To maintain air pressure

The correct answer is: To ensure they can reach the deepest part of the hole

The importance of checking the length of brushes and the end of an air nozzle during installation primarily revolves around ensuring that these tools can effectively access the deepest part of the drilled hole. The adhesive anchor installation process requires that the hole be properly cleaned to obtain maximum bond strength between the adhesive and the substrate. If the brush or nozzle is too short, it may not be able to reach areas that need cleaning, leaving debris or dust that can weaken the bond of the adhesive. A thorough cleaning helps remove any materials that could interfere with the adhesive’s performance, such as dust, oil, or loose particles. This is crucial for the successful installation of adhesive anchors, as any contaminants can lead to reduced strength and compromised anchor performance. Thus, verifying the length of these tools ensures that the cleaning process is complete and that the installation will yield the desired results.
