Step 8: Levelling the tower
1. Unhook the lifting cable from the gin-pole to avoid any influence of side pressure.
2. Take a spirit level and place it against tower 1
st
segment to observe the tower verticality. This
must be done at two sides of the tower, 90 degrees from each other.
TIP:
Using magnetic
pullet level will make the observation process easier.
3. Adjust the tower vertical by turning the M27 nuts supporting the base plate up and down as
necessary (see Figure 14). Lower the bottom nuts away from the upper nuts before levelling
out the tower.
! IMPORTANT:
Do the adjustment incrementally, 1 nut turn at the time. Never
remove the upper M27 nuts from the threaded bars, this could result in the tower falling down.
4. Once the tower is vertically levelled fix the M27 nuts cross wise with a torque of 1080 Nm,
going first 50% and then 100%.
5. Push the bottom counter nuts against the upper nuts and fix them with a torque of 540 Nm.

Step 9: Lowering the tower
1. Take the cable end with the hook and connect it to a lifting equipment. If you are using a car
with a winch, make sure that the car has all the brakes applied at all times and is anchored to
a strong point. The winch on the car must have a functional brake.
2. Use the lifting equipment to put slight pressure on the lifting cable and gin-pole.
3. Remove 6 of the M20 x 45 bolts connecting the tower base and 1
st
segment. Second person
can now catch the gin-pole and apply downward pressure.
! IMPORTANT:
DO NOT allow the
tower to start lowering by itself. This will but serious strain on the system.
