General Power Tool Safety
Warnings
WARNING Read all safety
warnings and instructions.
Failure to follow the warnings and
instructions may result in electric
shock, re and/or serious injury.
Save all warnings and
instructions for future reference.
The term ″power tool″ in the
warnings refers to your mains-
operated (corded) power tool.
Work area safety1.
Keep work area clean and well lit. a.
Cluttered or dark areas invite acci-
dents.
Do not operate power tools in b.
explosive atmospheres, such as in
the presence of ammable liquids,
gases or dust. Power tools create
sparks which may ignite the dust or
fumes.
Keep children and bystanders c.
away while operating a power tool.
Distractions can cause you to lose
control.
Electrical safety2.
Power tool plugs must match the a.
outlet. Never modify the plug in
any way. Do not use any adapter
plugs with grounded power tools.
Page 4SKU 45861 For technical questions, please call 1-800-444-3353.
Unmodied plugs and matching out-
lets will reduce risk of electric shock.
Avoid body contact with grounded b.
surfaces such as pipes, radiators,
ranges and refrigerators. There is
an increased risk of electric shock if
your body is grounded.
Do not expose power tools to rain c.
or wet conditions. Water entering
a power tool will increase the risk of
electric shock.
Do not abuse the cord. Never d.
use the cord to unplug the power
tool. Keep cord away from heat,
oil, sharp edges or moving parts.
Damaged or entangled cords in-
crease the risk of electric shock.
If operating a power tool in a damp e.
location is unavoidable, use a
Ground Fault Circuit Interrupter
(GFCI) protected supply. Use of
a GFCI reduces the risk of electric
shock.
Personal safety3.
Stay alert, watch what you are do-a.
ing and use common sense when
operating a power tool. Do not use
a power tool while you are tired
or under the inuence of drugs,
alcohol or medication. A moment
of inattention while operating power
tools may result in serious personal
injury.
Use safety equipment. Always b.
wear ANSI-approved eye protec-
tion. Safety equipment such as dust
mask, full face shield, heavy-duty
work gloves, non-skid safety shoes,
hard hat, or hearing protection used
for appropriate conditions will reduce
personal injuries.
Remove any adjusting key or c.
wrench before turning the power
tool on. A wrench or a key left at-
tached to a rotating part of the power
tool may result in personal injury.
Do not overreach. Keep proper d.
footing and balance at all times.
This enables better control of the
power tool in unexpected situations.
Dress properly. Do not wear loose e.
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.
If devices are provided for the con-f.
nection of dust extraction and col-
lection facilities, ensure these are
connected and properly used. Use
of these devices can reduce dust-
related hazards.
Power tool use and care4.
Do not force the power tool. Use a.
the correct power tool for your ap-
plication. The correct power tool will
do the job better and safer at the rate
for which it was designed.
Do not use the power tool if the b.
switch does not turn it on and off.
Any power tool that cannot be con-
trolled with the switch is dangerous
and must be repaired.
Disconnect the plug from the c.
power source before making any
adjustments, changing accesso-
ries, or storing power tools. Such
preventive safety measures reduce
the risk of starting the power tool ac-
cidentally.
Store idle power tools out of the d.
reach of children and do not allow
persons unfamiliar with the power
Page 5SKU 45861 For technical questions, please call 1-800-444-3353.
tool or these instructions to oper-
ate the power tool. Power tools are
dangerous in the hands of untrained
users.
Maintain power tools. Check for e.
misalignment or binding of moving
parts, breakage of parts and any
other condition that may affect the
power tool’s operation. If dam-
aged, have the power tool repaired
before use. Many accidents are
caused by poorly maintained power
tools.
Keep cutting tools sharp and f.
clean. Properly maintained cutting
tools with sharp cutting edges are
less likely to bind and are easier to
control.
Use the power tool, accessories g.
and tool bits etc. in accordance
with these instructions, taking into
account the working conditions
and the work to be performed. Use
of the power tool for operations differ-
ent from those intended could result
in a hazardous situation.
Service5.
Have your power tool serviced by a.
a qualied repair person using
only identical replacement parts.
This will ensure that the safety of the
power tool is maintained.
Lathe Safety Warnings
Maintain labels and nameplates on 1.
the tool. These carry important safety
information. If unreadable or miss-
ing, contact Harbor Freight Tools for a
replacement.
Do not run the Lathe without its cov-2.
ers and guards in place.
Use a brush or compressed air to 3.
remove metal shavings; never your
hands. The metal shavings will be
sharp.
The tool must always be tight within 4.
the tool post or chuck and adjusted
to limit projection from the post. This
will reduce the possibility of the tool
breaking or bending.
Avoid unintentional starting. Prepare 5.
to begin work before turning on the
tool.
Do not reach across the Lathe while it 6.
is running.
Industrial applications must follow 7.
OSHA guidelines.
Do not use the Lathe if it is off-bal-8.
ance, or the workpiece is not properly
centered.
Only feed workpiece into a cutting 9.
tool against the direction of rotation.
Do not leave the tool unattended 10.
when it is plugged into an electrical
outlet. Turn off the tool, and unplug it
from its electrical outlet before leav-
ing.
This product is not a toy. Keep it out 11.
of reach of children.
People with pacemakers should 12.
consult their physician(s) before use.
Electromagnetic elds in close prox-
imity to heart pacemaker could cause
pacemaker interference or pacemak-
er 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 Inter-
rupter (GFCI) should also be imple-
mented – it prevents sustained elec-
trical shock.
Some dust created by power sand-13.
ing, sawing, grinding, drilling, and
other construction activities, contains
chemicals known [to the State of Cali-
fornia] 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 ce-
ment or other masonry products
• Arsenic and chromium from chemi-
cally treated lumber
Your risk from these exposures var-
ies, 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 lter out microscopic
particles. (California Health & Safety
Code § 25249.5, et seq.)
The warnings, precautions, and in-14.
structions discussed in this instruction
manual cannot cover all possible con-
ditions 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 qualied
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
t the outlet, have a proper
outlet installed by a qualied
electrician.
Grounded Tools: Tools with Three
Prong Plugs
3-Prong Plug and Outlet
1. Tools marked with “Grounding Re-
quired” 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
Page 7SKU 45861 For technical questions, please call 1-800-444-3353.
of electric shock. (See 3-Prong Plug
and Outlet.)
The grounding prong in the plug is 2.
connected through the green wire in-
side 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.)
The tool must be plugged into an 3.
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
Grounded1. tools require a three wire
extension cord. Double Insulated
tools can use either a two or three
wire extension cord.
As the distance from the supply outlet 2.
increases, you must use a heavier
gauge extension cord. Using exten-
sion cords with inadequately sized
wire causes a serious drop in voltage,
resulting in loss of power and pos-
sible tool damage.
(See Table A.) The smaller the
gauge number of the wire, the greater
the capacity of the cord. For ex-
ample, a 14 gauge cord can carry a
higher current than a 16 gauge cord.
(See Table A.)
When using more than one exten-3.
sion cord to make up the total length,
make sure each cord contains at
least the minimum wire size required.
(See Table A.)
If you are using one extension cord 4.
for more than one tool, add the
nameplate amperes and use the sum
to determine the required minimum
cord size. (See Table A.)
If you are using an extension cord 5.
outdoors, make sure it is marked with
the sufx “W-A” (“W” in Canada) to
indicate it is acceptable for outdoor
use.
Make sure the extension cord is prop-6.
erly wired and in good electrical con-
dition. Always replace a damaged
extension cord or have it repaired by
a qualied electrician before using it.
Protect the extension cords from 7.
sharp objects, excessive heat, and
damp or wet areas.
