Installing the round arm (BL52)

7:1
WARNING
: Never raise the arm brackets by means of the crank, without the boom arm fixed for
counterbalancing the spring: the arm brakets would swing violently, with serious injury
risks for the operators.
Note: Fixing the arm requires two people!

Lower the arm brackets (7:1) with the crank (1:11), helping the movement by hand if necessary, until the
friction clutch slips (angle of about 20°).

Remove the three screws (7:2) and flat washers (7:3) from each arm lock plate (7:4). On delivery, the lock
plates are affixed on the arm brackets.

Insert the first arm segment (7:5) between the two arm brackets (7:1) as shown in Fig. 7a.

Insert both lock plates (7:4) successively inside the arm tube and fix a flat washer (7:3) and a screw (7:2)
again into the middle hole of each arm bracket. Raise the arm brackets (7:1) in the vertical position with the
crank, align them with the arm segment, and fix the flat washers (7:3) and the screws (7:2) into the upper
and lower holes of the arm brackets (Fig. 7b). Tighten the screws (7:2) firmly. The first arm segment is
now in place.

Lower the arm tube with the crank (1:11), helping the movement by hand if necessary, up to the horizontal
position. Continue turning the crank to make sure that the mechanism is locked.

After loosening the screws (9:10), insert the second segment (9:9) into the first and the third (9:11) into the
second, then align the red reflecting stripes.

Tighten the screws (9:10) firmly again to secure the second and third arm segments.

Check the alignment of the complete barrier with the roadway and adjust if necessary.

Install the shrouds now referred in paragraph [4.5. Fixing the shrouds].

Refer to paragraph [4.8 Installing the tip support] for installation of the tip support.
