Closer’s collar clockwise to thread it on to the
collet (see Figure 19).
25. Insert a piece of material into the collet and
turn the Collet Closer’s collar clockwise unl
desired tension is achieved on the workpiece.
IMPORTANT! Avoid excess tension on collet.
26. Move the collet handle back and forth between
the locked posion (away from the headstock)
and the released posion (toward the
headstock). Ensure handle is past centerline in
either posion (see Figure 20).
IMPORTANT! If collet handle is not past center
in the locked posion (see Figure 20), adjust
rod length unl proper alignment is achieved.
27. Temporarily remove Collet Closer from lathe
spindle assembly (see Figure 21).
28. Using ve Phillips-head screws, reaach Belt
Guard Cover to lathe.
29. Re-insert Collet Closer into lathe spindle

adjustments required to operate the collet
closer. You have now completed the installaon
(see Figure 22).
Operation
1. With a piece of material inserted in the collet,
ensure the Collet Closer is in the released
posion (see Figure 20), with the collet handle
toward the headstock.
2. Idenfy Index Pin on Collet Closer’s index plate
(see Figure 23).

3. Ensure the index pin is in the Pin Out posion
(see Figure 24).
NOTE: When the pin is in, the collet closer is in run
mode. When the pin is out, the collet closer is in
adjust mode.
4. Move the collet handle to the locked posion
(away from the headstock); ensure cams are
centered on the hub as shown in Figure 25.
If the cams are not centered on the hub:
• Rotate Stop Collar to access Set Screw on
Collet Closer (Figure 26); loosen set screw.
• Slide unit forward or backward unl cams
rest in center of hub as shown in Figure 25.
• When adjustment is complete, re-ghten
set screw on Collet Closer’s hub.
5. Move the Index Pin to the Pin In posion (see
Figure 24) by twisng to release and allowing
it to enter the closest hole in the index plate.
NOTE: If necessary, turn the collar slightly to allow the index pin to seat completely.
6. With the Index Pin in the Pin In posion, the collet closer is in run mode. You have now adjusted the collet
closer for operaon.

Troubleshooting
Problem Possible Cause Discussion
Handle wobbles
Runout on Index Ring/Adapter Ensure both sides of Index Ring/Adapter assembly are
free of debris (see Figure 7).
Connector and/or connector bracket
is too loose or too tight
Adjust bolts on connector and connector bracket as
necessary (see Figure 14).
Handle casting is not centered
Loosen top and bottom height screw locknuts (see
Figure 27) on Handle Casting and adjust set screws
until it is centered.

engage in index ring
Cams are not centered on the hub
Loosen Set Screw on Stop Collar (see Figure 26) and
slide unit until cams rest in the center of the hub (see
Figure 25). Re-tighten Set Screw.
Threaded rod is too long
Ensure handle is past centerline when in the locked
position (see Figure 20). If not, make adjustments to
threaded rod length – either cut the rod or tighten it
further into connector and/or connector bracket.
