Use Figures 70–71and the following descriptions to become familiar with the locations and functions of the controls that you will use to set up the correct power feed for your operation.

Note: Before using power feed, you may have to re-configure the end gears, depending on how they are set up. Refer to End Gears on Page 54 for detailed instructions.

Even though there is a lock-out device in the apron to prevent the feed selection lever and the half nut lever from being engaged at the same time, this lock-out device could break if forced. Attempting to engage these levers at the same time could cause severe lathe damage and will void the warranty.
