4.3.- Adjust the vertical position of the tower by means of the support plates (Q) turning
the handle (H) in the required sense in order to achieve that the bubble of the level (F)
become centered in the circle. It is necessary when leveling that the transporting
wheels will have to keep in contact with the ground as another supporting point
SEE FIGURE 2.
4.4.-Unlock the security trigger (R1). Extract the loading forks (U) removing safety bolts
(L),
and place them in position to support the load. Place the safety bolts.
SEE FIGURE 3.
The position of the loading forks (U) in position to charge must be such that the
indication be left in the topside and itself has a slope as is shown up in the following
figure.
SEE FIGURE 4.
4.5.- Place the load to lift on the forks of the tower by means of a suitable support,
so
that the load only aperate in vertical sense.
The load will have to be as minimal of 25
Kg. and it will never have to be more displaced of 25 cm
from the rear end of the
loading forks.
SEE FIGURE 5.
4.6.- Elevation:
Remove the brake (O) and t.
Check that the position of the Automatic Security System of the last profile is not
blocked, Position 1. Lift the tower turning the winch’s handle in clockwise (N
1
),
raising
the load to the required height. At the beginning the carriage will lift until the maximum
height of the last profile, then the carriage will be blocked by the Automatic Security
System of the last profile, so we will block that one. As soon as we wanted to continue
lifting the tower we will have to unlock the other Automatic Security Systems. In order to
unlock each one we must pull out the Automatic Security System and then we turn it in
clockwise, as it is shown in the figure 6. Once we reach the desired height we will block
all the Automatic Security Systems.
SEE FIGURE 6.
4.7.- Holaing on:
Release the winch’s handle (W), once we have blocked all the automatic security
systems.
SEE FIGURE 7.
The tower can be left in any intermediate needed position just releasing the handle,
and adjusting the height to one of the placement of the automatic security system.
It is recommended linking the winch’s handle with a chain to avoid the manipulation
by not authorized people.
4.8.- Descending:
The load descending is obtained by the opposite way. Turn the winch’s handle (W) in
counterclockwise (N
2
), Lowering the load lifting down the different profiles until the
tower become completely folded to its minimal height. At the same time you must pull
