• Jaw (7) in vertical position, remove a cap nut (1) and its associated flat washer (2), the threaded rod (3) and the spacer (4)
of the jaw.
• If it's not already done so, place the two spacers (5) at the two ends of the through holes and insert the spacer (4);
• Position the boom arm in an angled position to insert the threaded rod (3) through the jaw (7) and the boom arm (6).
• Replace the previously removed flat washer and cap nut on the threaded rod and tighten firmly.
• Bring the boom arm in its jaw in vertical position. Press the boom arm strongly so that it clips correctly between the synthetic
blocks (8).
• Bring the boom arm to its horizontal position and check its alignment and horizontality in relation to the roadway.
• If necessary, correct the position of the mechanism and definitively tighten the nuts (Rep. 36, Fig. 6, page 16) of the fixing
clamps.
