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.- Release the adjustment knob of the third profile. 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 and will be blocked
automatically in any position by the retention system.
SEE FIGURE 3.
4.5.- Up:
Turn the winch handle (W) clockwise (N1) to lift the load up to the required position,
then check that the automatic triggers are locked in so that the profiles are fixed
automatically. The safety triggers must always stay locked at the end of the lifting
process (1). This is achieved by descending the load by some centimetres once it has
reached its required position.
As the profiles extend, you must fix them with the adjustment knobs before releasing the
next profile (2).
As is shown in the previous picture, you must first secure the correct setting of the safety
trigger (1), only then the following adjustment knob will be released (2).
SEE FIGURE 4.
4.6.- Down:
Release the adjustment knob of the profile that was lifted last (step 1). Then release the
safety trigger (M1) (step 2). To release the safety triggers, it is necessary to lift the load
slightly with the winch and then release them. In the normal working position the weight
of load makes it impossible to free the safety triggers. Having unlocked the safety
trigger (M1), turn the winch handle counterclockwise (N2) to descend the load until the
first profile is at its bottom position (step 3).
SEE FIGURE 5.
Press the knob of profile #1 to fix it for transport. Release the knob of profile #2, free the
trigger (M2) and keep folding down the tower until this second profile is at its bottom
position. Press the knob of the profile #2 to fix it for transport. Release the knob of profile
#3, free the trigger (M3) and keep descending the load until the tower is completely
folded down to its minimal height.
Finally press the last knob that remains to avoid vibrations during transport.
