What is the first action taken when using a kelly bar attachment for an anchor installation?

When using a kelly bar attachment for an anchor installation, the first action typically involves setting the pins to the outer position. This adjustment is essential because it allows for the correct reach and depth needed for effective installation of the anchor. By extending the pins outward, you ensure that the attachment can operate in a wider range, which is important when dealing with the varying depths of soil or substrate that may be encountered during the installation process.

This orientation allows the kelly bar to engage properly with the ground, ensuring that the anchor installation is effective and secure. Proper pin setting is critical for maintaining stability and control during the drilling process, as well as for the safety of the crew and equipment involved in the operation.
