Attention
:
Fixing the shrouds requires two people!
The stainless steel bracing wires (
9:1
) are factory-fixed with the collar (
9:2
) on the arm.
When the three arm segments are fixed and secured to one another (see
paragraph 4.3 Installing the round
arm
), proceed as follows:
--
Unroll the cable (
9:1
) and pass it onto the upper screw of the collar (
9:2
), not forgetting to place the
eyelet.
--
Loosen the strainers (
9:3
) at maximum length.
--
Remove the security pin (
9:4
) and the axle (
9:5
) from the strainers.
--
Position the strainer (
9:3
) onto the wing (
9:6
) of the stretcher plates (
9:7
).
--
Insert the axle (
9:5
) into the wing of the stretcher plate and fix the security pin (
9:4
) again.
--
Tighten the strainers (
9:3
) so as to make the arm vertical in its open position and horizontal in its
closed position. If the precise positioning of the arm is not possible, see
paragraph 4.7.
Note
:
The figure above shows a two-stretcher assembly (arm length up to 11 metres). Proceed likewise
for a four-stretcher assembly (over 11 metres) or an eight-stretcher assembly (over 12 metres).
For the arms longer than 12 meters, after positioning the collars on the segment n° 3, drill and tap
4 M6 holes through the collars and the arm; then, fix these collars with M6 20mm-long screws.
