GENERAL SAFETY RULES
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS
Failure to follow all instructions listed below may result in
electric shock, fire, and/or serious injury.
SAVE THESE INSTRUCTIONS
WORK AREA
1. Keep your work area clean and well lit. Cluttered benches and dark areas invite
accidents.
2. 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.
3. Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control. Protect others in the work area from
debris such as chips and sparks. Provide barriers or shields as needed.

4. Grounded tools must be plugged into an outlet properly installed and grounded
in accordance with all codes and ordinances. Never remove the grounding
prong or modify the plug in any way. Do not use any adapter plugs. Check with
a qualified electrician if you are in doubt as to whether the outlet is properly
grounded. If the tools should electrically malfunction or break down, grounding
provides a low resistance path to carry electricity away from the user.
ELECTRICAL SAFETY
5. Double insulated tools are equipped with a polarized plug (one blade is wider
than the other). This plug will fit in a polarized outlet only one way. If the plug
does not fit fully in the outlet, reverse the plug. If it still does not fit, contact
a qualified electrician to install a polarized outlet. Do not change the plug in
any way. Double insulation eliminates the need for the three wire grounded
power cord and grounded power supply system.
6. 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.
7. Do not expose power tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
8. Do not abuse the Power Cord. Never use the Power Cord to carry the tools or
pull the Plug from an outlet. Keep the Power Cord away from heat, oil, sharp
edges, or moving parts. Replace damaged Power Cords immediately. Dam-
aged Power Cords increase the risk of electric shock.
9. When operating a power tool outside, use an outdoor extension cord marked
“W-A” or “W”. These extension cords are rated for outdoor use, and reduce the
risk of electric shock.
PERSONAL SAFETY
10. Stay alert. Watch what you are doing, and use common sense when operat-
ing a power tool. Do not use a power tool while tired or under the influence
of drugs, alcohol, or medication. A moment of inattention while operating power
tools may result in serious personal injury.
11. Dress properly. Do not wear loose clothing or jewelry. Contain long hair.
Keep your hair, clothing, and gloves away from moving parts. Loose clothes,
jewelry, or long hair can be caught in moving parts.
12. Avoid accidental starting. Be sure the Power Switch is off before plugging
in. Carrying power tools with your finger on the Power Switch, or plugging in power
tools with the Power Switch on, invites accidents.
13. Remove adjusting keys or wrenches before turning the power tool on. A

wrench or a key that is left attached to a rotating part of the power tool may result
in personal injury.
14. Do not overreach. Keep proper footing and balance at all times. Proper footing
and balance enables better control of the power tool in unexpected situations.
15. Use safety equipment. Always wear eye protection. Dust mask, nonskid safety
shoes, hard hat, or hearing protection must be used for appropriate conditions.
TOOL USE AND CARE
16. Use clamps (not included) or other practical ways to secure and support the
workpiece to a stable platform. Holding the work by hand or against your body
is unstable and may lead to loss of control.
17. Do not force the tool. Use the correct tool for your application. The correct
tool will do the job better and safer at the rate for which it is designed.
18. Do not use the power tool if the Power Switch does not turn it on or off. Any
tool that cannot be controlled with the Power Switch is dangerous and must be
replaced.
19. Disconnect the Power Cord Plug from the power source before making any
adjustments, changing accessories, or storing the tool. Such preventive safety
measures reduce the risk of starting the tool accidentally.
20. Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.
21. Maintain tools with care. Keep cutting tools sharp and clean. Properly main-
tained tools with a sharp cutting edge are less likely to bind and are easier to control.
Do not use a damaged tool. Tag damaged tools “Do not use” until repaired.
22. Check for misalignment or binding of moving parts, breakage of parts, and
any other condition that may affect the tool’s operation. If damaged, have
the tool serviced before using. Many accidents are caused by poorly maintained
tools.
23. Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitable for one tool may become hazardous when
used on another tool.
SERVICE
24. Tool service must be performed only by qualified repair personnel. Service
or maintenance performed by unqualified personnel could result in a risk of injury.
25. When servicing a tool, use only identical replacement parts. Follow instruc-
tions in the “Inspection, Maintenance, And Cleaning” section of this manual.

Use of unauthorized parts or failure to follow maintenance instructions may create
a risk of electric shock or injury.
SPECIFIC SAFETY RULES
1. Maintain labels and nameplates on the Mini Lathe. These carry important infor-
mation. If unreadable or missing, contact Harbor Freight Tools for a replacement.
2. Always wear ANSI-approved safety impact eye protection, full face shield and
heavy work gloves when using the Mini Lathe. Using personal safety devices
reduce the risk for injury. Safety impact eye goggles and heavy work gloves are
available from Harbor Freight Tools.
3. Maintain a safe working environment. Keep the work area well lit. Make sure
there is adequate surrounding workspace. Always keep the work area free of obstructions, grease, oil, trash, and other debris. Do not use a power tool in areas
near flammable chemicals, dusts, and vapors. Do not use this product in a damp
or wet location.
4. Always keep the extension cord away from moving parts on the tool.
5. Avoid unintentional starting. Make sure you are prepared to begin work before
turning on the Mini Lathe.
6. Never leave the Mini Lathe unattended when it is plugged into an electrical
outlet. Turn off the tool, and unplug it from its electrical outlet before leaving.
7. Always unplug the Mini Lathe from its electrical outlet before performing
any inspection, maintenance, or cleaning procedures.
8. WARNING! Some dust created by power sanding, sawing, grinding, drilling,
and other construction activities, contain 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.)

GROUNDING
WARNING!
Improperly connecting the grounding wire can result in the risk of electric shock.
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
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 Figure A.)
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 Figure A.)
3. Your 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 following illustration. (See Figure A.)
FIGURE A FIGURE B
DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS
4. Tools marked “Double Insulated” do not require grounding. They have a special
double insulation system which satisfies OSHA requirements and complies with
the applicable standards of Underwriters Laboratories, Inc., the Canadian Standard
Association, and the National Electrical Code. (See Figure B.)
SKU 93799 For technical questions, please call 1-800-444-3353. Page 6
5. Double insulated tools may be used in either of the 120 volt outlets shown in the
preceding illustration. (See Figure B.)
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 Figure C, next page.)
3. 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 Figure C.)
4. When using more than one extension cord to make up the total length, make sure
each cord contains at least the minimum wire size required. (See Figure C.)
5. If you are using one extension cord for more than one tool, add the nameplate am-
peres and use the sum to determine the required minimum cord size.
(See Figure C.)
6. If you are using an extension cord outdoors, make sure it is marked with the suffix
“W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
7. Make sure your extension cord is properly wired and in good electrical condition.
Always replace a damaged extension cord or have it repaired by a qualified electrician before using it.
8. Protect your extension cords from sharp objects, excessive heat, and damp or wet
areas.
