4.1 Clearance between wall and lower arm

Measure the clearance between left (E) and right (F) hand wall and lower arm (D). The clearance between arm and walls must be at least 3 mm. If the clearance is less than 3 mm the lower arm needs to be adjusted accordingly. See item "4.4 Longitudinal adjustment of lower arm". (Fig.6,7)

4.2 Aligning upper and lower arms

Check whether lower (D) and upper (G) arms are in line: the arms must overlap over a width of at least 8mm. –After aligning the arms continue with item "5.1Close the tailgate". –If the arms are not in line continue with following steps.

Adjust the lower arm on the front left hand side of the machine with threaded pin (K). –If the clearance measured under item "4.1 Clearance between wall and lower arm" on the left hand side was too small, push the left hand tensioning arm back. –If the clearance measured under item "4.1 Clearance between wall and lower arm" on the right hand side was too small, push the right hand tensioning arm forward. With this step the results obtained under item "4.1 Clearance between wall and lower arm" can be checked and corrected. (Fig.10) Tighten 4 bolts M16 and check the position of the adjustable stops (Q) during this procedure: –There must be a minimal clearance between the adjustable stops and arm (D): arm and stop must not touch. (Fig.11)
