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. Do not leave the tool unattended when the
Battery Pack is connected. Turn off the tool,
and remove the Battery Pack before leaving.
11. This product is not a toy.

12. 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.
13. 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. Never service damaged BATTERY packs. Service
of BATTERY packs should only be performed by
the manufacturer or authorized service providers.
3. 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 57670
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.
Battery tool use and care
1. Prevent unintentional starting. Ensure the switch is
in the off-position before connecting to battery pack,
picking up or carrying the power tool. Carrying the
power tool with your finger on the switch or energizing
power tool that have the switch on invites accidents.
2. Disconnect the battery pack from the
power tool before making any adjustments,
changing accessories, or storing power tool.
Such preventive safety measures reduce the
risk of starting the power tool accidentally.
3. Recharge only with the charger specified by
the manufacturer. A charger that is suitable
for one type of battery pack may create a risk
of fire when used with another battery pack.
4. Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
5. When battery pack is not in use, keep it away
from other metal objects, like paper clips,
coins, keys, nails, screws or other small metal
objects, that can make a connection from
one terminal to another. Shorting the battery
terminals together may cause burns or a fire.
6. Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid contacts
eyes, additionally seek medical help. Liquid ejected
from the battery may cause irritation or burns.
7. Do not use a battery pack or power tool that
is damaged or modified. Damaged or modified
batteries may exhibit unpredictable behavior
resulting in fire, explosion or risk of injury.
8. Do not expose a battery pack or power tool to
fire or excessive temperature. Exposure to fire or
temperature above 140°F may cause explosion.
Page 5For technical questions, please call 1-888-866-5797.Item 57670
9. Follow all charging instructions and do
not charge the battery pack or power tool
outside of the temperature range specified
in the instructions. Charging improperly or at
temperatures outside of the specified range may
damage the battery and increase the risk of fire.
10. Have servicing performed by a qualified
repair person using only identical
replacement parts. This will ensure that
the safety of the product is maintained.
11. Do not modify or attempt to repair the power
tool or the battery pack except as indicated
in the instructions for use and care.
12. The battery Charger gets hot during use.
The Charger’s heat can build up to unsafe
levels and create a fire hazard if it does
not receive adequate ventilation, due to
an electrical fault, or if it is used in a hot environment.
Do not place the Charger on a flammable surface.
Do not obstruct any vents on the Charger.
Especially avoid placing the Charger on carpets
and rugs; they are not only flammable, but they
also obstruct vents under the Charger. Place the
Charger on a stable, solid, nonflammable surface
(such as a stable metal workbench or concrete floor)
at least 1 foot away from all flammable objects, such
as drapes or walls. Keep a fire extinguisher and a
smoke detector in the area. Frequently monitor the
Charger and Battery Pack while charging.

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. Secure loose workpieces using included Clamp
or other clamping devices (sold separately)
to prevent movement while working.
Page 10 For technical questions, please call 1-888-866-5797. Item 57670
3. There must not be objects, such as utility lines,
nearby that will present a hazard while working.
4. 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.
5. Allow room on both left and right sides
of saw for extended workpieces.
6. Use additional supports if needed to ensure stability
of workpiece. Mount Saw so surface is level to
the ground, and additional supports to provide a
surface on same level as saw Turntable. If work
surface and any workpiece supports are not level,
and on same level, unwanted bevel angles will
appear in the cuts resulting in poor joinery.
7. Secure workpieces to saw Turntable using
included Clamp or other clamping devices
(sold separately). Securing 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
workpiece from moving during cutting operation.
General Instructions for Use
1. Make sure that the Trigger is in the off-position,
then attach the Battery Packs.
Sliding Miter Saw Cutting Procedure:
2. Press Saw Head down and pull
out Head Lock-Down Pin.
3. Check all adjustment knobs are tight (Miter
Lock Lever, Bevel Lock Knob, and Fence).
4. Blow any sawdust or debris away from
Fence. Place workpiece against Fence.
5. Aligning cut WITH Blade Guide: Turn Blade
Guide switch to ON. Pull Saw Head down
close to workpiece until Blade shadow appears
on workpiece. Align marked location of cut
on workpiece with edge of Blade shadow.
6. Aligning cut WITHOUT Blade Guide: Align
marked location of cut on workpiece with Blade.
To prevent workpiece from being cut too short,
align edge of Blade with measured mark, keeping
remainder of Blade on waste side of cut.
7. Hold workpiece in place using Clamp. Ensure
workpiece is level and supported securely.
Use saw horses or supports if necessary.
