2 Things to Know Before Starting your Sampler Parts Mechanism: Control Box: Power Supply: Familiarize with the Control Box before operating on a real experiment. Please follow the labels on your control box as they specify the direction of movement. Vacuum System: 12V, 10A CAUTION:

3 Starting and Operating Step 1: Place the mechanism on top of the target so that the frame falls in place. Step 2: Plug Control Box into the Power Supply. StartingStep 3: Plug in the vacuum hose marked “IN” to the top of the straight vacuum hose extension on the mechanism. Step 4: Plug in the vacuum pump and Power Supply to a power outlet.

Starting and Operating Step 1: Locate desired point for vacuum tip head. Step 2: Lower vacuum tip head until it touches the sand. Step 3: Push the start button to turn on the vacuum pump. Step 4: Lower vacuum tip to desired depth. WARNING: Removing more than 1.25in can result in too much torque on any of the motors. If this happens raise the vacuum tip head. Operating Step 5: Remove a 4in line of sand using the horizontal lead screw switch. Step 6: Take back to starting position and use the sprocket switch to move the mechanism to the following 4in line. Step 7: Repeat Steps 1-6 to remove layers until desired sampling depth. 3

Troubleshooting Emergencies WARNING: If at any point during usage you feel unsafe, TURN OFF the power to the Sampler IMMEDIATELY! Tensioning the Chain 1.Loosen the nut. 2.Screw in to tighten and unscrew to release chain tension. 3.Re-tighten nut to hold in place. 4
