General Power Tool Safety
Warnings
WARNING Read all safety warnings and instructions.
Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term ″power tool″ in the warnings refers to your mainsoperated (corded) power tool.
1.Work area safety
a.Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b.Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
c.Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
2.Electrical safety
a.Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with grounded power tools.
SKU 65345 | For technical questions, please call 1-800-444-3353. | Page 3 |
Unmodified plugs and matching outlets will reduce risk of electric shock.
b.Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded.
c.Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
d.Do not abuse the cord. Never use the cord to unplug the power tool. Keep cord away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric shock.
e.If operating a power tool in a damp location is unavoidable, use a Ground Fault Circuit Interrupter (GFCI) protected supply. Use of
a GFCI reduces the risk of electric shock.
3.Personal safety
a.Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired
or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
b.Use safety equipment. Always wear ANSI-approved eye protection. Safety equipment such as NIOSH-approved dust mask/respirator, full face shield, heavy-duty work gloves, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
c.Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
d.Do not overreach. Keep proper footing and balance at all times.
This enables better control of the power tool in unexpected situations.
e.Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
4.Power tool use and care
a.Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
b.Do not use the power tool if the switch does not turn it on and off.
Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
c.Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
d.Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
e.Maintain power tools. Check for misalignment or binding of moving
SKU 65345 | For technical questions, please call 1-800-444-3353. | Page 4 |
parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
f.Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
g.Use the power tool and its accessories in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
5.Service
a.Have your power tool serviced by a qualified repair person using only identical replacement parts.
This will ensure that the safety of the power tool is maintained.
Lathe Safety Warnings
1.Maintain labels and nameplates on the Lathe. These carry important safety information. If unreadable or missing, contact Harbor Freight Tools for a replacement.
2.Do not run the Lathe without its covers and guards in place.
3.Tighten all locks before operating.
4.Do not mount a split workpiece.
5.Use the lowest speed when starting a new workpiece.
6.Always stop the Lathe at its slowest speed. If the Lathe is run so fast that it vibrates, there is a risk that the workpiece will be thrown or the cutting tool jerked from your hands.
7.Always rotate the workpiece by hand before turning on the Lathe. If the workpiece strikes the tool rest, it could split and be thrown out of the Lathe.
8.Do not allow cutting tools to bite into the workpiece. The wood could be split or thrown from the Lathe.
9.Always position the tool rest above the centerline of the Lathe when shaping a piece of stock.
10.Before attaching a workpiece to the faceplate, always rough it out to make it as round as possible. This minimizes the vibrations while the piece is being turned. Always fasten the workpiece securely to the faceplate. Failure to do so could result in the workpiece being thrown away from the Lathe.
11.Remove all loose knots in the workpiece before mounting between the centers or on the faceplate.
12.Position your hands so they will not slip onto the workpiece when the
Lathe is running.
13.Use a brush or compressed air to remove wood shavings; never your hands. The wood shavings will be sharp.
14.The cutting tool must always be tight within the tool post or chuck and adjusted to limit projection from the post. This will reduce the possibility of the tool breaking or bending.
SKU 65345 | For technical questions, please call 1-800-444-3353. | Page 5 |
15.Avoid unintentional starting. Prepare to begin work before turning on the tool.
16.Do not reach across the Lathe while it is running.
17.Industrial applications must follow OSHA guidelines.
18.Do not use the Lathe if it is off-bal- ance, or the workpiece is not properly centered.
19.Only feed workpiece into a cutting tool against the direction of rotation.
The workpiece must always be rotating toward you.
20.Do not leave the tool unattended when it is plugged into an electrical outlet. Turn off the tool, and unplug it from its electrical outlet before leaving.
21.This product is not a toy. Keep it out of reach of children.
22.People with pacemakers should consult their physician(s) before use.
Electromagnetic fields in close proximity to heart pacemaker could cause pacemaker interference or pacemaker failure. In addition, people with pacemakers should:
•Avoid operating alone.
•Do not use with power switch locked on.
•Properly maintain and inspect to avoid electrical shock.
•Any power cord must be properly grounded. Ground Fault Circuit Interrupter (GFCI) should also be implemented – it prevents sustained electrical shock.
23.Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities, contains chemicals known [to the State of California] to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
•Lead from lead-based paints
•Crystalline silica from bricks and cement or other masonry products
•Arsenic and chromium from chemically treated lumber
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. (California Health & Safety Code § 25249.5, et seq.)
24.The warnings, precautions, and instructions discussed in this instruction manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator.
Save these instructions.

Grounding
To prevent electric shock
and death from incorrect grounding wire connection:
Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the power cord plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the power cord or plug is damaged. If damaged, have it repaired by a service facility before use. If the plug will not fit the outlet, have a proper outlet installed by a qualified electrician.
Grounded Tools: Tools with Three Prong Plugs
This product uses a 3-prong plug.
3-Prong Plug and Outlet
1.Tools marked with “Grounding Required” have a three wire cord and three prong grounding plug. The plug must be connected to a properly grounded outlet. If the tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user, reducing the risk
of electric shock. (See 3-Prong Plug and Outlet.)
2.The grounding prong in the plug is connected through the green wire inside the cord to the grounding system in the tool. The green wire in the cord must be the only wire connected to the tool’s grounding system and must never be attached to an electrically “live” terminal. (See 3-Prong Plug and Outlet.)
3.The tool must be plugged into an appropriate outlet, properly installed and grounded in accordance with all codes and ordinances. The plug and outlet should look like those in the preceding illustration. (See 3-Prong
Plug and Outlet.)
Extension Cords
1.Grounded tools require a three wire extension cord. Double Insulated tools can use either a two or three wire extension cord.
2.As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage.
(See Table A.) The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
(See Table A.)
3.When using more than one extension cord to make up the total length, make sure each cord contains at

Cutting Procedures
The instructions that follow are basic operational procedures. It is assumed that the operator understands lathe operation and it’s capabilities.
1.Rotate Turn Lever (C) counterclockwise to move the saddle outward.
2.Place the workpiece in the chuck, center, and secure with the chuck key.
3.Loosen the Straight Lever (H) and then rotate the Turn Lever (I) clockwise to engage the Dead Center tool into the end of the workpiece. Tighten Straight Lever (H) again.
4.Select the desired tool set and place it into the tool rest. Align the tool nose to the spindle centerline, then tighten.
5.Open the Gear Box and verify that the proper
speed is engaged.
Typically, the harder the metal workpiece, the faster the spindle speed.
6.Set the desired feed amount according to the type of stock, workpiece dimensions, and the type of cut.
7.Close the Gear Box.
8.Open the safety cover over the On / Off switch and press the green On button. Verify that the lathe head and feed amount is correct.
9.Align the tool nose on the workpiece where the cut is to begin.
10.Rotate the Turn Lever (C) clockwise to move the saddle transversely, moving the tool nose into the workpiece for cutting.
11.When the cut is complete, press the red Off button.
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.When the cut is complete, press the red Off button.
Optionally, you can turn the Reverse switch to have the tool go over the same cut in the opposite direction (left-to-right). This will clean and smooth the previous cut.
6.When the cut is complete, press the red Off button.
Machining Cones
Manually
This operation is similar to machining cylinders with the following differences.
1.To manually cut a cone, determine the taper requirement and turn the small cutter rest to the desired slope on the workpiece. Retighten the cutter rest.
2.Press the green On button to start the lathe.
3.Turn the Straight Lever (F) clockwise to make the cut.
Automatically
Central Machinery Lathe User Manual Parts
1.To automatically cut a cone, determine the taper requirement and turn the small cutter rest to the desired slope on the workpiece. Retighten the cutter rest.
2.Horizontally move the tailstock from the spindle centerline to the required slope on the far right surface of the work piece.
3.Press the green On button to start the lathe.
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.Repeat steps 2 through 4 until the desired cone size is cut.
Central Machinery T33274 Lathe Manual
6.When the cut is complete, press the red Off button.
Machining Threads
The Gear Box is composed of the change gears, shaft bolt, fixing shaft bolt, and square nut. The change gear box is fixed on the left support of the leadscrew (101). To cut threads, select the proper change gears for the desired thread type (see Thread Formula Table), and engage with approximately 0.1 mm tolerance. Tighten Screw (835).
SKU 44859 | Page 7 |
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. If the two settings “0.1 and 0.2”, of the Gear table do not meet the requirement, you can add or change gears. The same is true if the number of teeth listed in the Gear table do not coincide with the calculated number of teeth. In this case, use gears with similar number of teeth. In doing so, however, the following relationship of the driving shaft must be met: Z3+Z4+>Z2+Z5. Otherwise, the addendum of circles A2 and Z5 will hit each other.
The left formula below is an example of 0.3 mm spindle round. The right formula is an example for 8 threads per inch.
The Thread to Gear settings table on the following page allows you to select the number of threads per inch or millimeter, and which gears need to be used.
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.
Maintenance
General
1.Unplug power cord from receptacle when not in use.
2.Using compressed air, blow off all dirt and particles after using.
3.Keep all tools sharp.
4.Cover Lathe when not in use.
5.Periodically, check all bolts and nuts for tightness.
