4. Select

the

47.0 mm regular auger head. Note: This auger is designed for all soils and

should be used where possible, even in heavy textured soils, as it provides the best
possible access tube installation method. The other augers are used to take over when you
run into problems. See the Troubleshooting Section for further information.

5. Select the required extension rods and screw the 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. 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 extension(s) onto the existing auger extension and

refit the T-Handle.

6. The total length of the auger should be a minimum of 20 cm longer than the access tube.

Push the auger through the access tube until the auger head protrudes by 20 cm. Use the
marking pen to mark the auger extension rod at the point where it disappears into the top of
the access tube. This mark is later used to show the depth to which to auger.
