Rough Adjustment

Maintenance

If rough adjustments need to be made to the collet closer assembly:

1.In the event that the previous adjustments fail to allow the collet to lock onto the mater- ial or the draw tube fails to touch the collet, adjust the adapter hub in or out.

2.Loosen the setscrews and turn the hub adapter in a clockwise direction if the draw tube does not contact the back of the collet.

3.Turn the hub adapter counter-clockwise if the work material cannot be locked by the collet.

4.Tighten the setscrews.

The Model G8143 Collet Closer is adjusted prop- erly when the 3 collet locking pawls are tight on the cam and the workpiece will not twist in the collet. Again, Figure 12 on page 7 shows the proper locked position of the collet locking pawls around the cam.

The Model G8143 Collet Closer is essential- ly a maintenance free tool; however, some things to keep in mind are:

1.Make sure that all the components of your collet closer are assembled correctly, according to this manual.

2.Once the replacement stud and hub adapter are installed, they will not need to be removed.

3.Ensure that your locking mechanism is work- ing properly before you start any projects on your lathe.

4.Check the locking stroke for proper place- ment of locking pawls on the cams.

5.The bearings are non-serviceable. If you have problems with your bearings, you must order a new bearing pack.

6.The hub adapter must be removed in order to change gears occasionally.
