Spring Adjustment
9.4
The higher the spring screw (blue box), the tighter the spring and the greater the
tension. The lower the spring screw (blue box), the looser the spring, and the lesser the
tension.
Notes:
1.
When the barrier boom is at 45°, it is the best balance.
2.
The spring wire diameter is adapted to different boom lengths: 3m boom with φ4.5mm;
4.5m boom with φ5.5mm; 6m boom with φ6.5mm. (If the boom is too short i.e., less
than 2m, do not install the spring).
