2. As the probe enters the prepared hole in the soil, it shaves off a soil residue that is eventually stored

in the cutting tip or falls to the bottom of the hole.

3. Slide the dolly rubber to the top of the EasyAG dolly. Insert the EasyAG dolly into the access tube

and position it on top of the joiner at the base of the access tube. Gently slide the dolly rubber into
the top cap to stabilize the EasyAG dolly.

4. Continue inserting the probe by hammering on the insertion dolly with a sledgehammer until there is

a 2.5 cm (1 inch) gap between the base of the top cap and the edge of the stabilization plate tube
guide.

5. Feed the cable through the cable gland into the top cap. It is simpler to push the cable through the

cable gland at this point than when the access tube is installed in the ground.

6. Remove the stabilization plate wing nuts.

7. Remove the stabilization plate pins and separate the 2 halves of the stabilization plate.

8. Continue inserting the probe into the ground with gentle blows of the sledgehammer using the

EasyAG dolly, until the base of the top cap is level with the ground. This will place the top sensor at
10 cm (3.9 inches) below the ground surface. Remove the EasyAG dolly.

Fitting the top cap lid

1. Carefully slide the probe into the access tube, ensuring that the top of the probe seats correctly into

the grooves in the top cap. Connect the cable to the green phoenix connector on the top of the
probe.

2. Pull the excess cable back through the cable gland. The outer sheath of the cable should be

trimmed back as far as the point where the cable enters the inside of the top cap. Apply silicone
around the wires of the cable at the end of the outer sheath, to prevent moisture from traveling along
the cable into the inside of the top cap.

3. Ensure that the sealing gasket on the top cap is clean, in good condition and positioned correctly,

and replace the lid of the top cap. Tighten the screws completely to ensure an effective seal.

4. The probe is now installed and upon connection to the data logger is ready for use.
