This guide is written as such to be a shortened version the Kuster Operations Manual provided by the company with pictures included. It is highly recommended to read the operations manual to get familiar with the tool.

The operation procedure of this tool can be broken down into four parts: Preparing for sampling, Downhole operations, Extracting the sample, and cleaning and maintenance.

Preparing for Sampling

1. Remove the following components

                   Bull nose                                                                   Clock housing

    2. Open the valves

First by depressing the lower spring(Fig. 3) followed by pressing a small tool into the small hole at the top end of the tool to overcome the top spring(fig. 4). You will hear a small click when the valves are locked open. After the valves are locked open the springs will be almost fully depressed(fig. 5, 6). Remember the lower valve must be opened first!

Press the top of the timer down towards its body and rotate it so that the desired time is aligned with the mark on the frame, then release. Be careful not to go too far as it cannot be turned back. You will have to wait.
