• Know your tool. Learn the tool's operation, application and specific limitations. • Use recommended accessories (refer to page 15). Use of improper accessories may cause risk of injury to persons. • Handle workpiece correctly. Protect hands from possible injury. • Turn machine off if it jams. Drill bit or cutter jams when it digs too deeply into workpiece. (Motor force keeps it stuck in the work.) Do not remove workpiece until the mill drill is turned off, unplugged and the spindle has stopped.

Check with a qualified electrician if grounding instructions are not understood or if in doubt as to whether the tool is properly grounded. . Secure chip pan to supports using hex head bolts and flat washers (Key Nos. 2 and 3). This tool is equipped with an approved 3 conductor cord rated at 300V. A qualified electrician should wire appropriate 3-prong plug to mill drill line cord.
Do not use a 3-prong to 2-prong grounding adapter unless permitted by local and national codes and ordinances. (A 3-prong to 2-prong grounding adapter is not permitted in Canada.) Where permitted, the rigid green tab or terminal on the side of the adapter must be securely connected to a permanent electrical ground such as a properly grounded water pipe, a properly grounded outlet box or a properly grounded wire system. NOTE: Using extension cords over 50 ft. long is not recommended.
