Instructions for Mounting Indexing Assembly (Optional Accessory)

1.Remove the handwheel. Loosen the two set screws and slide the handwheel off.

2.If your lathe was purchased before January 1998, you must drill a 1/4" hole into the headstock so that the indexer will work properly. Before the 1/4" hole can be drilled you must first make sure that the 1/4" hole will line up with the holes in the indexer. To do this you will need a small center punch that can be placed through one of the tapped holes in the indexer. Install the indexer onto the spindle. Slide the indexer up to the headstock leaving approximately an 1/8" gap between the face of the indexer and the headstock. (The hub of the indexer, which has the two set screw holes, should be pointing away from the headstock.) Using one of the tapped holes in the indexer as a guide, place the center punch through one of the holes in the indexer. With a hammer, strike the end of the center punch making a mark on the headstock.

3.Remove the indexer from the spindle.

4.Using a 1/4" drill bit, drill a hole at the mark made by the center punch.

5.Install the indexer onto the spindle. Slide the indexer up to the headstock leaving approximately an 1/8" gap between the face of the indexer and the headstock.

6.Locate one of the set screws on the indexer over the keyway slot on the spindle. Tighten securely both set screws.

7.Install indexing pin into the indexer by screwing it into one of the tapped holes. The indexing pin knob should be turned until the indexing pin engages the 1/4" drilled hole. Tighten indexing pin securely.

8.Remove indexing pin from indexer before operating lathe!
