The Foredom uses a stand that is connected to the table. You will need to clip the motor hanger bracket to the clip on the stand. This will allow the stand to carry the weight of the motor. The preferred hand piece will need to be selected and installed as well as the desired tool. The tools are captivated by the collet located inside the hand piece. To lock the shaft find the hole located on the side of the hand piece. Install the locking pin into the hole so the shaft can't turn. You will now be able to use the wrench to loosen the collet. Install the tool and reverse the process to lock the tool in place. Make sure to remove the locking pin before trying to run the motor.
