Fit the Oz-post onto
the driving mandril and locate the tip of the Oz-post over
the insertion point.
Raise the entire
assembly to vertical using the Oz-post as a pivot.
Drive the Oz-post
into the ground a short distance until it supports the Jackhammer
(usually 100mm or so is sufficient).
Check for level on
two sides at 90 degrees with a small level and adjust for
vertical as required using the Jackhammer for leverage. Adjustments
to level are best done whilst driving.
Drive the Oz-post
in a further 50-100mm and recheck for level.
Continue this driving
and levelling process until satisfied that the support is
staying properly aligned. With signpost supports this is usually
achieved at a little over halfway through the driving process.
Finish the driving
process when the base of the housing is at ground level OR
if so desired the housing may be completely submerged.
In the case of signpost supports it is rarely necessary
to remove any topsoil prior to driving as the Jackhammer
quite easily compacts the surface material. However, with
larger series e.g. 100mm x 100mm sleeves it may be necessary
to remove a spadeful of surface material before commencing
Once past the halfway mark it becomes increasingly
difficult to change the alignment. It is much better to
spend a little extra time and care using the level in the
initial stages of driving to ensure the desired result than
to have to remove the support from the ground with the Ozpost
Extractor and start again.
Sometimes an underground obstruction may cause the support
to "drift" off-line. In this instance it is better
to stop the driving process, remove the support, select
a slightly different site and start again.
You will need:2 TS65 Oz-post fixing wedges.
The OZ-POST is normally installed so that the
base of the sleeve is at ground level. However, the sleeve
may be fully submerged if so desired and secured using two
TS65 wedges, in opposition, one in each "ear". Needless
to say any recommended fixing method may be altered by the
user to suit their particular requirements.(e.g.1/4"
galvanised bolts, spot welding or self drilling screws.)
Allows quick removal of oz-posts with ease
Removes all Oz-Posts whether the sleeve is out of the
ground or fully submerged !
The simple construction allows assembly for use and
dismantling for transport in seconds
