4. Operation
4.1.- Place the tower on a flat and solid surface in its site of operation.
4.2.- Pull the legs out of their support for transport (S) and insert them in their working
lodges (V). Check that they are fully inserted and fastened by the retaining safety
triggers (R).
SEE FIGURE 1.
4.3.- Adjust the vertical alignment of the tower with the support plates (Q) by turning the
handle (H) in the required sense until the bubble of the level (F) becomes centered in
the circle.
SEE FIGURE 2.
4.4.- Attach the load to the tower using an adequate support (this may vary according
to the situation), so that it can move only in a vertical sense. The minimum load must be
25 kg.
SEE FIGURE 3.
4.5.- Up:
Unlock the safety bolt (M2) and extend the tower by turning the winch handle (W)
clockwise (N1), thereby lifting the load to the desired location.
SEE FIGURE 4.
4.6.- Hold:
Release the winch handle (W), it will be kept in that position by the action of the
automatic brake pulled by the load. Lock this first profile with the safety bolt (M2) fixing
it to profile 2.
SEE FIGURE 5.
4.7.- Continue elevating:
Turn the winch handle (W) again clockwise and lift the load until the second profile is
fully extended. Release the handle which will remain fixed by the winch's automatic
brake and lock the second profile with the safety bolt (M2).
SEE FIGURE 6.
The tower may be stopped in any desired intermediate position. Simply release the
winch handle and secure the tower by inserting the corresponding safety bolt into the
hole which is closest to the required position.
4.8.- Down:
First release the safety trigger (M1). To free the safety triggers it is necessary to lift the
load slightly with the winch to release them. In the normal working position the weight
of the load makes it impossible to free the safety triggers. After unlocking the safety
trigger (M1) turn the winch handle counterclockwise (N2) thereby descending the load,
until the first profile is at its bottom position. Now release the safety trigger (M2) and
continue to fold down the tower until the second profile is in its bottom position.
SEE FIGURE 7.
Just like when lifting the load, the tower can be left in any desired intermediate position.
