Installing the oval arm (BL53)

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.
Attention: Fixing the oval arm requires at least two persons, depending on its length! In case of difficulty, the
use of a crane is highly advisable.

Remove the three screws (8:1) and flat washers (8:2) from the twin arm bracket (8:3).

Insert the arm tube (8:4) vertically inside the arm bracket (8:3), if necessary using a crane.

Fix the flat washers (8:2) and screws (8:1) again. Tighten the screws (8:1) firmly.

Lower the arm with the crank (1:11) up to the horizontal position. Continue turning the crank to make sure
that the mechanism is locked. Check the alignment of the arm tube with the arm bracket.

Check the alignment of the complete barrier with the roadway and adjust if necessary.

If no tip support is to be installed, tighten the nuts (6:7) firmly to lock the barrier on the sealing frame.
