3.18.- For transportation it is necessary to retract all profiles and lock them with the
adjustment knobs.
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. When leveling the tower, the transport wheels must have firm contact with
the ground as another supporting point.
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 the required position.
As the profiles extend, you must fix them with the adjustment knobs before releasing the
next profile (2).
SEE FIGURE 4.
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).
4.6.- 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 nearest safety trigger and press the
adjustment knob to eliminate the play between the profiles.
SEE FIGURE 5.
4.7.- 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
