INSTALLING AND ADJUSTING THE SPRING
• Select the desired opening direction as indicated in paragraph 11.4.
• Unlock the barrier (see chapter 21) and move the boom into the completely open vertical position.
• Select the most suitable spring (see tables in paragraph 12.1).
• The springs are colour coded for identification. The coloured part of the spring must always be at the top.:
–
blue - Ø61 springs (
AG/SP61/01
);
–
red - Ø72 springs (
AG/SP72/01
).
• Unscrew the upper screw TE M14x60 of the spring (viewed from the top coloured side).
• Unscrew the screw TE M14x45 from the linkage lever and fasten the spring with the same screw (fig. 9):
• - For barriers with left-side opening, use the SX1 or SX2 holes.
• - For barriers with right-side opening, use the DX2 or DX3 holes.
• Fasten the springs to the fixed structure (fig. 9), on the steel cross bar of the barrier, using the screws TE M14x60 included in the package.
• Lubricate the pivot points with lithium based grease (EP LITIO) (fig. 10). Available upon request, article
RS/GR1/100
: 100 g can of lithium grease.
• To adjust the spring tension, loosen the nuts [
A
] as indicated in fig. 10-11. Then turn the spring [
B
] clockwise to reduce the tension or anticlockwise
to increase tension (fig. 11).
• Lift the boom manually to an angle of 45° and let go. If the boom rises, reduce the spring tension. If the boom drops, increase the spring tension.
• Once the spring tension is correct, tighten the nuts securely [
A
].
