replacement parts. Use of any other parts will void the warranty. Only use accessories intended for use with this tool. Approved accessories are available from Harbor Freight Tools. 18. Do not operate tool if under the influence of alcohol or drugs. Read warning labels on prescriptions to determine if your judgment or reflexes are impaired while taking drugs. If there is any doubt, do not operate the tool. 19. Use proper size and type extension cord.
Installation 1. Carefully place the Lathe on a sturdy, level work table with sufficient light. 2. Use appropriate hardware (not included) in the mounting holes of the lathe base, to properly secure the lathe. The work table must also be properly mounted to the floor. 3. Before operation, verify that the slide, worktable, and spindle can move, and are not locked in place. 4.
Lathe Safety Precautions 1. Keep fingers away from revolving parts and cutting tools while in operation. 2. Never force cutting action. 3. Never perform an abnormal or little used operation without study and use of adequate blocks, jigs, stops, and fixtures. 4. Verify proper cutting speed for the material being cut, and any special operation, in a machinery shop handbook. 5. Do not open drive cover while in operation. 6. Always remove chuck key from chuck. 7.
Machining Cylinders 1. Repeat the cutting procedure steps 1 through 8, listed on the previous page. 2. Rotate Turn Lever (D) clockwise and move the saddle to the right of the workpiece. 3. Rotate Turn Lever (C) clockwise until the desired depth of cut is reached on the far right surface of the work piece. 4. Press down on the Straight Lever (G) to engage apron clasp nut over the Gear Shaft. The tool will automatically move from right to left while cutting the workpiece. 5.
The Fixed Shaft Bolt (825) under the spindle is used for right hand cutting and threading. The set of Fixed Shaft Bolts in the accessory kit is used in combination with the original set of Shaft Bolts to reverse the rotation of the long leadscrew for left-handed threading and cutting. The change gear for metric or inch threading is selected according to the Thread to Gear formula and table. The feed amount depends on the material to be cut, the surface roughness, and finish requirements.
Rest Accessories The Follow Rest (not supplied) is mainly used for cutting long and thin shaft pieces to ensure no bending takes place during cutting. It also provides a better finish surface as a result of less vibration. The Steady Rest (not supplied) provides a similar function as with the Follow Rest. The difference being that the Steady Rest is fixed on the bed guides, and does not follow the movement of the cutting tool. Both rests can be purchased from Harbor Freight Tools.
