Fig. 6 4-2. Changing the lever and fixed jig setup 1. Pull the stopper rack and disengage the center gear from the rack as shown in Fig.5. 2. Loosen the limit screw as shown in Fig.7. If the limit screw is not loosened, the lever case will stop halfway even if the primary gear is turned, and it will not move to the lever replacement position. - Page 18 Fig.7 ・ Make sure that the stopper rack is fully pushed in before gripping the workpiece. If it is not pushed in completely, there is a risk of the workpiece flying off due to poor gripping, which is dangerous. ・ Make sure that the alignment mark on the fixed jig is within the wheel size scale range and that the limit screw is tightened before rotating the chuck.

Page 22: Usage
5. Usage This product is a device to fix an automotive aluminum wheel when it is processed by the lathe machine or the rotary table. The rotary cylinder closes the levers and fixes an automotive aluminum wheel so that it does not move during processing. -
Page 23: Precautions Related To Processing
5-2. Precautions related to processing <1> Unbalance ・ In the case of processing largely unbalanced work, lower the rotation speed. The work will fly out and this is dangerous. ・ Vibrations are generated if there is unbalance owing to the work or the jig, etc. Vibration not only will impart a negative influence on the process precision but also the endurance of the chuck being remarkably shortened, and the chuck may break. -
