UNPACKING When unpacking, check to make sure all the parts shown on the Parts Lists on page 13 are included. If any parts are missing or broken, please call Harbor Freight Tools at the number shown on the cover of this manual as soon as possible. PRODUCT FEATURES NOTE: For additional references to the parts listed in the following pages, refer to the Assembly Diagram on page 14. 1. The Lathe Bed (part #57) is made of cast iron and is T-ribbed, which ensures rigidity and low vibration.
5. The Cross Slide (part #28) runs right and left along the Lathe Bed (part #57) and can be locked in place using the Screw (part #29). A Hand Wheel (part #36) is used to move the Cross Slide to the right (counterclockwise) and to the left (clockwise) along the Lathe Bed. One complete turn of the Handwheel will move the Cross Slide .065”. (See Figure C.) 6. The Longitudinal Slide (part #35) is mounted above the Cross Slide (part #28) and can be locked in place by tightening the Socket Screw (part #40).
10. The Lathe Spindle (part #23) turning speed is adjustable and allows the operator to run the Spindle speed at either 130 RPM, 200 RPM, 350 RPM, 560 RPM, 920 RPM, 1,500 RPM, 2,450 RPM, AND 4,000 RPM. The correct speed depends on the diameter and hardness of the workpiece. The larger the workpiece, the slower the speed. The harder the workpiece, the slower the speed. (See Figure F.) ASSEMBLY AND OPERATING INSTRUCTIONS To Assemble The 3-Jaw Chuck For A Workpiece Up To 1” Diameter: 1.
To Assemble The 3-Jaw Chuck For A Workpiece Up To 2” Diameter: 1. Workpieces with a diameter of up to 2” should be gripped with the external jaws of the 3-Jaw Chuck (part #67). (See Figure E.) 2. If necessary, reverse the jaws for external gripping. To do so, unscrew, remove, and clean each of the three jaws. Turn the knurled tension ring until the beginning of the spiral thread comes to the respective groove. (See Figure D.) 3. The jaws are then inserted in the following order: (See Figure D.) A.
