3.Move the feed movable block (4) so that the pin (5) goes smoothly into the indexer holes (38.1 mm - (A), 44.45 mm - (B), 50.8 mm - (C), 57.15 mm - (D)).

4.Place the stopper block (6) firmly against the feed movable block (4), and then tighten the bolt (1) to secure it in place.

Using the set screw collar

Using the set screw collar makes it easy to change between two different hole spacing settings. The right-hand set screw collar can be used to set the smaller hole spacing, and the left-hand screw collar can be used to set the larger hole spacing.

5.From now on, if you want to have hole intervals of

38.1mm (1-1/2”), move the stopper block (2) so that it is against the right-hand set screw collar (1) and secure it in this position, and if you want to have hole intervals of 44.45 mm (1-3/4”), move the stopper block (2) so that it is against the left-hand set screw collar (4) and secure it in this position.
