IMPORTANT SAFETY INFORMATION
Read all safety warnings and all 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.
Save all warnings and instructions
for future reference.
The term “power tool” in the warnings refers
to your mains-operated (corded) power tool or
battery-operated (cordless) 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 earthed (grounded)
power tools. Unmodified plugs and matching
outlets will reduce risk of electric shock.
b. Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges
and refrigerators. There is an increased risk of
electric shock if your body is earthed or 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
for carrying, pulling or unplugging 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. When operating a power tool outdoors,
use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor
use reduces the risk of electric shock.
f. 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 personal protective equipment. Always
wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
c. Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools
with your finger on the switch or energizing power
tools that have the switch on invites accidents.
d. 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.
e. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
f. 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.
g. If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
dust collection can reduce dust-related hazards.
h. Do not let familiarity gained from frequent
use of tools allow you to become
complacent and ignore tool safety
principles. A careless action can cause
severe injury within a fraction of a second.
i. Only use safety equipment that has been
approved by an appropriate standards agency.
Unapproved safety equipment may not provide
adequate protection. Eye protection must be
ANSI-approved and breathing protection
must be NIOSH-approved for the
specific hazards in the work area.
j. Avoid unintentional starting.
Prepare to begin work before turning on the tool.
k. 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.
l. This product is not a toy.
Keep it out of reach of children.

m. 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 Trigger locked on.
• Properly maintain and inspect to avoid
electrical shock.
• Properly ground power cord.
Ground Fault Circuit Interrupter (GFCI)
should also be implemented – it prevents
sustained electrical shock.
n. 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.
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 and/or remove the battery pack,
if detachable, from the power tool 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 and accessories.
Check for misalignment or binding of moving
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, accessories 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 different from those
intended could result in a hazardous situation.
h. Keep handles and grasping surfaces
dry, clean and free from oil and grease.
Slippery handles and grasping surfaces
do not allow for safe handling and control
of the tool in unexpected situations.
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.
b. Maintain labels and nameplates on the tool.
These carry important safety information.
If unreadable or missing, contact
Harbor Freight Tools for a replacement.
6. Guarding related warnings
a. Keep guards in place. Guards must be in
working order and be properly mounted. A
guard that is loose, damaged, or is not functioning
correctly must be repaired or replaced.
b. Always use saw blade guard, Riving Knife
and anti-kickback device for every throughcutting operation. For through-cutting operations
where the saw blade cuts completely through the
thickness of the workpiece, the guard and other
safety devices help reduce the risk of injury.
c. Immediately reattach the guarding system
after completing an operation (such as
rabbeting, dadoing or resawing cuts)
which requires removal of the guard,
Riving Knife and/or anti-kickback device.
The guard, Riving Knife, and anti-kickback
device help to reduce the risk of injury.
d. Make sure the saw blade is not contacting
the guard, Riving Knife or the workpiece
before the switch is turned on. Inadvertent
contact of these items with the saw blade
could cause a hazardous condition.
e. Adjust the Riving Knife as described in this
instruction manual. Incorrect spacing, positioning
and alignment can make the Riving Knife
ineffective in reducing the likelihood of kickback.
f. For the Riving Knife and anti-kickback
device to work, they must be engaged in the
workpiece. The Riving Knife and anti-kickback
device are ineffective when cutting workpieces
that are too short to be engaged with the Riving
Knife and anti-kickback device. Under these
conditions a kickback cannot be prevented by
the Riving Knife and anti-kickback device.
g. Use the appropriate saw blade for the
Riving Knife. For the Riving Knife to function
properly, the saw blade diameter must
match the appropriate Riving Knife and the
body of the saw blade must be thinner than
the thickness of the Riving Knife and the
cutting width of the saw blade must be wider
than the thickness of the Riving Knife.

7. Cutting procedures warnings
a. DANGER: Never place your fingers or
hands In the vicinity or in line with the
saw blade. A moment of inattention or a
slip could direct your hand towards the saw
blade and result in serious personal injury.
b. Feed the workpiece into the saw blade
only against the direction of rotation.
Feeding the workpiece in the same direction
that the saw blade is rotating above the
table may result in the workpiece, and your
hand, being pulled into the saw blade.
c. Never use the miter gauge to feed the
workpiece when ripping and do not use
the Rip Fence as a length stop when cross
cutting with the miter gauge. Guiding
the workpiece with the Rip Fence and the
miter gauge at the same time increases the
likelihood of saw blade binding and kickback.
d. When ripping, always apply the workpiece
feeding force between the fence and
the saw blade. Use a push stick when the
distance between the fence and the saw
blade is less than 150mm, and use a push
block when this distance is less than 50mm.
“Work helping” devices will keep your hand
at a safe distance from the saw blade.
e. Use only the push stick provided by the
manufacturer or constructed in accordance
with the instructions. This push stick provides
sufficient distance of the hand from the saw blade.
f. Never use a damaged or cut push stick.
A damaged push stick may break causing
your hand to slip into the saw blade.
g. Do not perform any operation “freehand”.
Always use either the Rip Fence or the miter
gauge to position and guide the workpiece.
“Freehand’ means using your hands to support
or guide the workpiece, in lieu of a Rip Fence
or miter gauge. Freehand sawing leads to
misalignment, binding and kickback.
h. Never reach around or over a rotating saw
blade. Reaching for a workpiece may lead to
accidental contact with the moving saw blade.
i. Provide auxiliary workpiece support to the
rear and/or sides of the saw table for long
and/or wide workpieces to keep them level.
A long and/or wide workpiece has a tendency
to pivot on the table’s edge, causing loss of
control, saw blade binding and kickback.
j. Feed workpiece at an even pace. Do not bend
or twist the workpiece. If jamming occurs, turn
the tool off Immediately, unplug the tool then
clear the jam. Jamming the saw blade by the
workpiece can cause kickback or stall the motor.
k. Do not remove pieces of cut-off material while
the saw is running. The material may become
trapped between the fence or inside the saw blade
guard and the saw blade pulling your fingers into
the saw blade. Turn the saw off and wait until
the saw blade stops before removing material.
l. Use an auxiliary fence in contact with the
table top when ripping workpieces less
than 2mm thick. A thin workpiece may wedge
under the Rip Fence and create a kickback.
8. Kickback causes and related warnings
Kickback is a sudden reaction of the workpiece due
to a pinched, jammed saw blade or misaligned line
of cut in the workpiece with respect to the saw blade
or when a part of the workpiece binds between the
saw blade and the Rip Fence or other fixed object.
Most frequently during kickback, the workpiece is
lifted from the table by the rear portion of the saw
blade and is propelled towards the operator.
Kickback is the result of saw misuse and/or incorrect
operating procedures or conditions and can be avoided
by taking proper precautions as given below.
a. Never stand directly in line with the saw blade.
Always position your body on the same side of
the saw blade as the fence. Kickback may propel
the workpiece at high velocity towards anyone
standing in front and in line with the saw blade.
b. Never reach over or in back of the saw blade
to pull or to support the workpiece. Accidental
contact with the saw blade may occur or kickback
may drag your fingers into the saw blade.
c. Never hold and press the workpiece
that is being cut off against the rotating
saw blade. Pressing the workpiece being
cut off against the saw blade will create
a binding condition and kickback.
d. Align the fence to be parallel with the saw
blade. A misaligned fence will pinch the workpiece
against the saw blade and create kickback.
e. Use a featherboard to guide the workpiece
against the table and fence when making nonthrough cuts such as rabbeting, dadoing or
resawing cuts. A featherboard helps to control
the workpiece in the event of a kickback.
f. Use extra caution when making a
cut into blind areas of assembled
workpieces. The protruding saw blade may
cut objects that can cause kickback.
g. Support large panels to minimise the risk
of saw blade pinching and kickback. Large
panels tend to sag under their own weight.
Support(s) must be placed under all portions
of the panel overhanging the table top.
Page 4 For technical questions, please call 1-888-866-5797. Item 64855
h. Use extra caution when cutting a workpiece
that is twisted, knotted, warped or does
not have a straight edge to guide it with a
miter gauge or along the fence. A warped,
knotted, or twisted workpiece is unstable
and causes misalignment of the kerf with
the saw blade, binding and kickback.
i. Never cut more than one workpiece, stacked
vertically or horizontally. The saw blade could
pick up one or more pieces and cause kickback.
j. When restarting the saw with the saw
blade in the workpiece, center the saw
blade In the kerf so that the saw teeth are
not engaged in the material. If the saw
blade binds, it may lift up the workpiece and
cause kickback when the saw is restarted.
k. Keep saw blades clean, sharp, and with
sufficient set. Never use warped saw
blades or saw blades with cracked or broken
teeth. Sharp and properly set saw blades
minimize binding, stalling and kickback.
9. Table saw operating procedure warnings
a. Turn off the table saw and disconnect
the power cord when removing the table
insert, changing the saw blade or making
adjustments to the Riving Knife, antikickback device or saw blade guard, and
when the machine Is left unattended.
Precautionary measures will avoid accidents.
b. Never leave the table saw running unattended.
Turn it off and don’t leave the tool until it
comes to a complete stop. An unattended
running saw is an uncontrolled hazard.
c. Locate the table saw in a well-lit and level
area where you can maintain good footing
and balance. It should be installed in an area
that provides enough room to easily handle the
size of your workpiece. Cramped, dark areas,
and uneven slippery floors invite accidents.
d. Frequently clean and remove sawdust
from under the saw table and/or the dust
collection device. Accumulated sawdust
is combustible and may self-ignite.
e. The table saw must be secured. A table saw
that is not properly secured may move or tip over.
f. Remove tools, wood scraps, etc. from the
table before the table saw is turned on.
Distraction or a potential jam can be dangerous.
g. Always use saw blades with correct size
and shape (diamond versus round) of
arbor holes. Saw blades that do not match
the mounting hardware of the saw will run
off-center, causing loss of control.
h. Never use damaged or incorrect saw blade
mounting means such as flanges, saw blade
washers, bolts or nuts. These mounting
means were specially designed for your saw,
for safe operation and optimum performance.
i. Never stand on the table saw, do not
use it as a stepping stool. Serious injury
could occur if the tool is tipped or if the
cutting tool is accidentally contacted.
j. Make sure that the saw blade is installed
to rotate in the proper direction. Do not use
grinding wheels, wire brushes, or abrasive
wheels on a table saw. Improper saw
blade installation or use of accessories not
recommended may cause serious injury.
Grounding
TO PREVENT ELECTRIC SHOCK AND
DEATH FROM INCORRECT
GROUNDING WIRE CONNECTION READ
AND FOLLOW THESE INSTRUCTIONS:
Grounded Tools: Tools with
Three Prong Plugs
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.)
Page 5For technical questions, please call 1-888-866-5797.Item 64855
Double Insulated Tools: Tools
with Two Prong Plugs
Outlets for 2-Prong Plug
1. 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.
2. Double insulated tools may be used in either of the
120 volt outlets shown in the preceding illustration.
(See Outlets for 2-Prong Plug.)
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.)
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 Table A.)
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 Table A.)
5. If you are using one extension cord for more
than one tool, add the nameplate amperes
and use the sum to determine the required
minimum cord size. (See Table A.)
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 the 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 the extension cords from sharp objects,
excessive heat, and damp or wet areas.

Vibration Safety
This tool vibrates during use. Repeated or long-term
exposure to vibration may cause temporary or permanent
physical injury, particularly to the hands, arms and
shoulders. To reduce the risk of vibration-related injury:
1. Anyone using vibrating tools regularly or for an
extended period should first be examined by a
doctor and then have regular medical check-ups
to ensure medical problems are not being caused
or worsened from use. Pregnant women or
people who have impaired blood circulation to
the hand, past hand injuries, nervous system
disorders, diabetes, or Raynaud’s Disease should
not use this tool. If you feel any medical or
physical symptoms related to vibration (such as
tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
3. Use tools with the lowest vibration when there
is a choice between different processes.
4. Include vibration-free periods each day of work.
5. Grip workpiece as lightly as possible (while still
keeping safe control of it). Let the tool do the work.
6. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.
