Locking Ring Installation Procedure
Use the Spindle Index Pin to lock the headstock spindle before commencing.
Step 1:
Thread the M33 ASR faceplate or chuck onto the spindle thread all the way in. Check that the spindle and the
faceplate/chuck are touching at the clamping ridge.
Step 2:
Put the lower part of the locking ring under the clamped rings.
Step 3:
Put the upper part of the locking ring above the clamped rings.
Step 4:
Use an Allen key to tighten up two bolts on the locking ring.
Unlock the spindle Index Pin before turning the machine on.
IMPORTANT NOTE: The Index Pin is designed for indexing purposes only, not for leveraging against
when removing faceplates, inserts and chucks. For this we recommend holding the spindle using a
spanner to clamp the lathe hand brake mounting surface.
