Step 2 – Auger the hole

To manually auger the access tube hole

1. Select

the

required

extension rods and screw the regular 61.0 mm (slurry) auger head and

T-handle to the extension rods.

Note: To add extra extension tubes to an existing auger assembly,

place the auger on the ground. Place one foot on either side of the T-

Handle and insert the Tommy bar into the hole of the extension tube

below the T-handle. Loosen the extension rod from the T-Handle using

one quick jerk of the Tommy bar. When loose, remove the Tommy bar

and unscrew these two parts until separated. Screw the additional

extensions onto the existing auger extension and then refit the T-

Handle.

2. Put on gloves to increase your grip on the equipment and to protect your hands from heated

metal when installing on hot days.

3. Auger the hole to the required depth.

4. Insert the access tube with slurry bottom stopper fitted into the hole to check the depth level,

and then remove the access tube. The top of the access tube should protrude out of the hole
by 4 cm (1.6 inches) for the top cap to sit flush with the ground. This will place the centre of
the first sensor 10 cm below the ground surface.
