3. Fit the Auger Centralization Poly Guide over the extension and attach the T-Handle.
4. Put gloves and safety goggles on to protect your hands and eyes from damage.
5. Insert the assembled auger into the tripod ensuring the centralization poly guide is fitted to
the top of the tripod cylinder.
6. Turn the auger 4-5 turns and lift it gently approximately five centimetres, then turn the auger
another 3-4 turns. The lifting action moves the soil upward, partially filling the space around
the auger head and providing a greater uptake for additional soil. Note: Do not try to auger
too much soil at one time, as the auger may over-fill with soil, making it difficult to remove
from the hole.
7. Clean the auger head then repeat the process to the required depth of installation.
Hint:
If the augering becomes too difficult, attach the Heavy Duty T-Handle
and reinforced extension rods, and gently tap the top of the T-Handle
with the sledge hammer between auger turns to assist the auger in
“biting” into the soil.
8. When augering is complete, check the final depth with a measuring tape to ensure you have
enough depth for your tube length. To position the middle of the first sensor at 10 cm below
the ground surface, ensure that 4 cm of access tube is protruding above the ground.
9. Fit the red metal cutting edge squarely onto the access tube.
10. Place the access tube fitted with cutting edge in the tripod guide and insert the Heavy Duty
Dolly into the top of the access tube.
11. To prevent the access tube from flexing, attach extension rods to the Heavy Duty Dolly,
ensuring they are firmly tightened.
12. Ensure you have safety goggles on and drive the access tube into the ground using the
sledge hammer. If the driving of the access tube becomes too strenuous, use the 47 mm
regular auger to clean out the soil shavings repeatedly from the inside of the access tube.
Continue hammering until you have reached the final depth.
