IMPORTANT SAFETY INFORMATION
GENERAL POWER TOOL SAFETY WARNINGS
Read all safety warnings, instructions, illustrations
and specifications provided with this power tool.
Failure to follow all instructions listed below 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 mains-operated (corded) power tool or
battery-operated (cordless) power tool.
Work area safety
1. Keep work area clean and well lit.
Cluttered or 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 children and bystanders away
while operating a power tool. Distractions
can cause you to lose control.
Electrical safety
1. 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.
2. 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.
3. Do not expose power tools to rain or wet
conditions. Water entering a power tool
will increase the risk of electric shock.
4. 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.
5. 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.
6. 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.
Personal safety
1. 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.
2. 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.
3. 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.
4. 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.
5. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
6. 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.
7. 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.
8. 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.
9. 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.
10. Avoid unintentional starting.
Prepare to begin work before turning on the tool.
11. 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.
12. This product is not a toy.
Keep it out of reach of children.

Page 3For technical questions, please call 1-888-866-5797.Item 56682
13. 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.
14. 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.
Power tool use and care
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
7. 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.
8. 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.
Service
1. 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.
2. Maintain labels and nameplates on the tool.
These carry important safety information.
If unreadable or missing, contact
Harbor Freight Tools for a replacement.
Safety instructions for mitre saws
1. Mitre saws are intended to cut wood or wood-
like products, they cannot be used with abrasive
cut-off wheels for cutting ferrous material such
as bars, rods, studs, etc. Abrasive dust causes
moving parts such as the lower guard to jam.
Sparks from abrasive cutting will burn the lower
guard, the kerf insert and other plastic parts.
2. Use clamps to support the workpiece whenever
possible. If supporting the workpiece by hand,
you must always keep your hand at least 100
mm from either side of the saw blade. Do not
use this saw to cut pieces that are too small to
be securely clamped or held by hand. If your
hand is placed too close to the saw blade, there
is an increased risk of injury from blade contact.
3. The workpiece must be stationary and
clamped or held against both the fence
and the table. Do not feed the workpiece
into the blade or cut ″freehand″ in any way.
Unrestrained or moving workpieces could be
thrown at high speeds, causing injury.
4. Push the saw through the workpiece. Do
not pull the saw through the workpiece. To
make a cut, raise the saw head and pull it out
over the workpiece without cutting, start the
motor, press the saw head down and push
the saw through the workpiece. Cutting on
the pull stroke is likely to cause the saw blade to
climb on top of the workpiece and violently throw
the blade assembly towards the operator.
5. Never cross your hand over the intended line of
cutting either in front or behind the saw blade.
Supporting the workpiece ″cross handed″ i.e. holding
the workpiece to the right of the saw blade with
your left hand or vice versa is very dangerous.
6. Do not reach behind the fence with either hand
closer than 100 mm from either side of the saw
blade, to remove wood scraps, or for any other
reason while the blade is spinning. The proximity
of the spinning saw blade to your hand may not
be obvious and you may be seriously injured.

Page 4 For technical questions, please call 1-888-866-5797. Item 56682
7. Inspect your workpiece before cutting. If the
workpiece is bowed or warped, clamp it with
the outside bowed face toward the fence.
Always make certain that there is no gap
between the workpiece, fence and table along
the line of the cut. Bent or warped workpieces
can twist or shift and may cause binding on the
spinning saw blade while cutting. There should
be no nails or foreign objects in the workpiece.
8. Do not use the saw until the table is clear
of all tools, wood scraps, etc., except for
the workpiece. Small debris or loose pieces of
wood or other objects that contact the revolving
blade can be thrown with high speed.
9. Cut only one workpiece at a time. Stacked multiple
workpieces cannot be adequately clamped or braced
and may bind on the blade or shift during cutting.
10. Ensure the mitre saw is mounted or placed
on a level, firm work surface before use.
A level and firm work surface reduces the
risk of the mitre saw becoming unstable.
11. Plan your work. Every time you change the bevel
or mitre angle setting, make sure the adjustable
fence is set correctly to support the workpiece
and will not interfere with the blade or the
guarding system. Without turning the tool ″ON″ and
with no workpiece on the table, move the saw blade
through a complete simulated cut to assure there will
be no interference or danger of cutting the fence.
12. Provide adequate support such as table
extensions, saw horses, etc. for a workpiece
that is wider or longer than the table top.
Workpieces longer or wider than the mitre saw
table can tip if not securely supported. If the cut-
off piece or workpiece tips, it can lift the lower
guard or be thrown by the spinning blade.
13. Do not use another person as a substitute for a
table extension or as additional support. Unstable
support for the workpiece can cause the blade to bind
or the workpiece to shift during the cutting operation
pulling you and the helper into the spinning blade.
14. The cut-off piece must not be jammed or
pressed by any means against the spinning
saw blade. If confined, i.e. using length
stops, the cut-off piece could get wedged
against them blade and thrown violently.
15. Always use a clamp or a fixture designed
to properly support round material such as
rods or tubing. Rods have a tendency to roll
while being cut, causing the blade to ″bite″ and
pull the work with your hand into the blade.
16. Let the blade reach full speed before
contacting the workpiece. This will reduce
the risk of the workpiece being thrown.
17. If the workpiece or blade becomes jammed, turn
the mitre saw off. Wait for all moving parts to
stop and disconnect the plug from the power
source and/or remove the battery pack. Then
work to free the jammed material. Continued
sawing with a jammed workpiece could cause
loss of control or damage to the .mitre saw.
18. After finishing the cut, release the switch, hold
the saw head down and wait for the blade to stop
before removing the cut-off piece. Reaching with
your hand near the coasting blade is dangerous.
19. Hold the handle firmly when making an
incomplete cut or when releasing the switch
before the saw head is completely in the
down position. The braking action of the
saw may cause the saw head to be suddenly
pulled downward, causing a risk of injury.
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:
a. 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.
b. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
c. Use tools with the lowest vibration when there
is a choice between different processes.
d. Include vibration-free periods each day of work.
e. Grip workpiece as lightly as possible
(while still keeping safe control of it).
Let the tool do the work.
f. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.

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
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.)
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 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.)
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.

4. Repeat the process for the other
Fence Knob and Sliding Fence.
Workpiece and Work Area Set Up
1. Designate a work area that is clean and well lit.
The work area must not allow access by children
or pets to prevent distraction and injury.
2. Route the power cord along a safe route to reach
the work area without creating a tripping hazard or
exposing the power cord to possible damage. The
power cord must reach the work area with enough
extra length to allow free movement while working.
3. Secure loose workpieces using a vise or clamps
(not included) to prevent movement while working.
4. There must not be objects, such as utility lines,
nearby that will present a hazard while working.
5. Cut only the following materials:
dimensional lumber, plywood, particle board, plastic.
Note: Use caution to avoid overheating the cutting tips.
If cutting plastic, cut at an even pace to avoid melting it.
6. Allow room on both left and right sides
of saw for extended workpieces.
7. Use additional supports if needed to ensure
the stability of the workpiece. Mount the Saw
so that the surface is level to the ground, and
additional supports to provide a surface on the
same level as the saw table. If the work surface
and any workpiece supports are not level, and
on the same level, unwanted bevel angles will
appear in the cuts resulting in poor joinery.
8. Secure workpieces to the saw table using the Clamp
or other clamping devices (not included). Securing
the workpiece will provide safety by preventing kick
back and by removing the need to hold workpieces
near the blade by hand. Clamping the workpiece
will also improve cutting accuracy by preventing the
workpiece from moving during the cutting operation.
Using the Workpiece
Extension Supports
1. The Table Extensions are inserted into
each side of the Table, and locked in place
using the Table Extension Knobs.
2. When properly installed, the upper face of
the Table Extensions are level with the Table,
and provide a wider support surface for the
workpiece. Each Extension has a stop lever
which can be raised to make repetitive cuts.
3. Support the workpiece to be level with the table,
and so that after the cut is made the cut off pieces
will not fall. Use sawhorses or other supports
(not included) to support longer workpieces.
4. If the workpiece is not level, you will make
an unintentional bevel cut in the material.
If the workpiece is not supported, it will bind
the blade and may cause the material to
kick back, potentially causing injury.

General Instructions for Use
1. Make sure that the Trigger is in the
off-position, then plug in the tool.
WARNING! TO PREVENT SERIOUS INJURY:
The tool will restart automatically if stalled.
Sliding Miter Saw Cutting Procedure:
2. Unlock the Head Lock-Down Pin.
3. Check that all adjustment knobs are tight
(Miter Lock Knob, Bevel Lock Lever,
Fence and Table Extension Knobs).
4. Blow any sawdust or debris away from the Fence.
Place the work material against the Fence.
5. Align the marked location of the cut on
the work material with the saw blade.
6. Note: To prevent your workpiece from being
cut too short, align the edge of the blade
with the measured mark, keeping the rest of
the blade on the waste side of the cut.
7. Hold the work material in place using the Clamp.
Ensure that the work material is level and supported
securely. Use saw horses or supports if necessary.
DANGER! TO PREVENT SERIOUS
INJURY AND DEATH: Saws can quickly
amputate fingers if misused.
Keep hands well clear of cutting area.
8. Grip the Saw Handle, press one of the
Trigger Locks with your thumb, and
squeeze the Trigger to start the Saw.
9. Note: If the laser guide line does not line
up with the cut line, release Trigger and
reposition workpiece before making the cut.
10. Use two hands and hold workpiece securely
against table and fence at all times.
11. With narrow material, press down lightly to
cut the workpiece. Press straight down,
“chopping” the material. Do not bear down on
the material — use light downward pressure.
If the material binds the blade, release the Trigger.
12. With wide material, move the Blade across
the workpiece while cutting as follows:
13. Loosen Slide Lock Knob and pull
Saw Head Assembly forward.
14. Press down on the Saw Handle.
15. Push the Saw Head toward the rear to
make the cut. Refer to Figure F.
16. Do not bear down on the material — use light
downward and lateral pressure. If the material
binds the blade, release the Trigger.

to stop turning, release the Clamp and
remove the workpiece from the Saw.
18. To prevent accidents, turn off the tool and
unplug it after use. Clean, then store the
tool indoors out of children’s reach.
19. Lock the head down and lock all other
adjustments before moving the saw. Use the
handle cut outs on each end of the base to
lift and support the Saw while moving it.
