5.5.5 HOW TO ADJUST THE REFERENCE FORKS
— Swing the ring nut (1, fig. 5.8) to move the holder (2) of reference forks (3) till you read on the
graduated scale (4) the measure that represents the distance («d», fig. 5.7) in mm from the
crimping point on the corner.
— Once the measure adjusted, loose the washer (5), then move the block (6) with the small
graduated scale till zero on this scale (6) corresponds with the adjusted value; then lock the
washer (5).
— Swing again the ring nut (1) till you read on the scale of sliding block the adjustment value
calculated as follows:
Regulation value = profile wall thickness + clearance between profile and
inside corner
— Position a sample profile against the reference forks (3).
— Adjust the height of reference forks (3) by swinging the ring nut (7)until they are aligned with the
profile, around the middle of the lower corner's chamber (fig. 5.7).
— Remove the sample profile and close the safety guard.
