  Read and understand the entire contents of this manual before attempting set-up or 

operation!  Failure to comply may cause serious injury. 

CAUTION

The three jaw chuck and the face plate have a set screw on their flanges that secures them to the 
threaded spindle. Before removing the three jaw chuck or the faceplate, remove the set screw 
completely from the flange. Failure to remove the set screw may cause damage to the threads on 
the spindle. When installing either the jaw chuck or the faceplate, tighten the set screw firmly to 
prevent the chuck or the faceplate from coming off the spindle during operation.
