3.
Remove the
lower
bolts in the other two legs, and loosen the upper bolts in
these legs just enough to allow the tower to be tilted when a small amount of
force is applied.
4.
Gently lower the tower to the ground, supporting and packing the structure as
necessary to avoid damage to the sensors or other delicate equipment.
When the tower is safely on the ground you can check and maintain the sensors or
any other equipment as required. If re-alignment of sensors is necessary, you may
have to remove the top section of the mast and proceed as outlined in Section 2.3
of this manual.
After all necessary maintenance has been carried out, re-erect the tower following
the procedures given in Section 2.6. Re-check all three guy wires for security and
carry out any other maintenance such as rust prevention as detailed above.
Low-Level Sensors and equipment
If you have lowered the tower for maintenance of the high-level sensors as detailed
above, you may wish to check all other equipment at the same time.
Alternatively sensors and the enclosure etc. which are mounted at a lower level,
but which may be above head height, can be maintained by using a suitable
stepladder.
