WARNING For safety reasons, do not erect the mast alone. At least 4 persons are needed, depending on the number of equipment installed on the mast.
WARNING Before erecting the mast, verify that it has not been damaged during the handling.
WARNING Before erecting the mast, see the installation and aiming instructions of the additional sensors and devices. It is important to aim the sensors correctly before erecting the mast.
WARNING Before erecting the mast, see that guy wires 2 and 3 are attached also by their lower ends, so that the mast does not fall down.
WARNING Be careful when erecting or lowering the mast. Check that there are no power lines or other obstacles above the mast or close to the guy wires.
WARNING Disconnected guy wires may present a safety hazard. Make sure your clothing and equipment do not get tangled in the wires.
Wear protective eyewear, gloves, and a safety helmet.
  1. Move the assembled mast body close to the base hinge.
  2. Before erecting the mast, check that:
    • Bolts of the guy attachment collar are tight.
    • Guy wires 2 and 3 are secure.
  3. To eliminate excess slack, pre‑tighten the guy wires. This prevents the mast from tilting over.
  4. Erect the mast carefully by pulling guy wire 1 and lifting the mast.
  5. Connect guy wire 1 (opposite the tilting direction) with fasteners to its foundation.
  6. Lift the bottom end of the mast body, and fix it from the lowest mast tube to the base hinge using the upper hinge bolt.
  7. Securely attach a locking bolt on the side opposite to the mast tilting direction.

    This prevents the mast from falling over in that direction when erecting the mast.

  8. When the mast is in an upright position and the holes in the lowest mast tube and base hinge are aligned, fit the lower hinge bolt and the other locking bolt into place.

  9. Tighten the nuts of the locking bolts.
  10. Check with a spirit level that the mast is vertical.

    If the mast is not vertical, adjust the guy wires, and check the position of the mast again. Make sure that each guy wire is tight.

    CAUTION Do not overtighten the guy wires because this may bend and damage the mast.
  11. Place the black and yellow cable shrouds on the guy wires.
