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.
ELECTRICAL SAFETY
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.
5.
6.
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.
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.
8.
Do not expose power tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
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 immedi-
ately. Damaged 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.
11.
Stay alert. Watch what you are doing, and use common sense when oper-
ating a power tool. Do not use a power tool while tired or under the influ-
ence of drugs, alcohol, or medication. A moment of inattention while operat-
ing power tools may result in serious personal injury.
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.

15.
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.
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.
Do not overreach. Keep proper footing and balance at all times. Proper
footing and balance enables better control of the power tool in unexpected situa-
tions.
Use safety equipment. Always wear eye protection. Dust mask, non-skid
safety shoes, hard hat or hearing protection must be used for appropriate condi-
tions
TOOL USE AND CARE
16.
Use clamps or other practical ways to secure and support the workpiece to
a stable platform. Holding the work by hand is unstable and may lead to loss of
control. Only work on a workpiece that is properly secured.
17.
18.
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.
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.
21.
Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting tools sharp and clean. Properly
maintained 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 re-
paired.
22.
23.
Check for misalignment or binding of guards and other moving parts,
breakage of parts, cracking or breakage of the Saw Blade, 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.
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.

manual. Use of unauthorized parts or failure to follow maintenance instructions
may create a risk of electric shock or injury.
SPECIFIC SAFETY RULES
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 the Miter Saw in
areas near flammable chemicals, dusts, and vapors. Do not use this product in a
damp or wet location.
2.
3.
Maintain labels and nameplates on the Miter Saw. These carry important
information. If unreadable or missing, contact Harbor Freight Tools for a replace-
ment.
Do not force the equipment. This Miter Saw will do the work better and safer
at the speed and capacity for which it was designed.
4.
5.
6.
Keep all guards in place and in working order.
Remove all adjusting wrenches from the Miter Saw before turning it on.
Do not abuse the Power Cord. Do not use the Power Cord to pull its Plug from
an electrical outlet. Keep the Power Cord away from heat, oil, sharp edges, and
moving parts. Route the Power Cord safely. Protect the Power Cord from being
damaged by other equipment in the work area. Do not route the Power Cord
where it can be walked on or tripped over. Replace a damaged Power Cord
immediately.
7.
8.
9.
Do not use this Miter Saw for cutting metals or brittle materials. Do not cut
dangerous materials, such as asbestos which can cause harmful dust or vapors.
To avoid accidental injury, always wear heavy duty work gloves when
changing a Saw Blade.
Before using the Miter Saw, make sure the Saw Blade is properly mounted
on the Saw Spindle. Make sure the Saw Blade is balanced, and is not cracked
or bent.
10.
11.
12.
13.
The Saw Blade will become hot while cutting. Allow the Saw Blade to com-
pletely cool before touching.
Make sure the workpiece is free from nails and any other foreign objects
which can damage the Saw Blade.
Keep your body positioned to either side of the Saw Blade, but not in line
with the Saw Blade. “Kickback” can cause the Saw to jump backwards.
Causes and operator prevention of “kickback”: Kickback is a sudden reaction
to a pinched, bound, or misaligned Saw Blade, causing an uncontrolled Saw to lift
up and out of the workpiece toward the operator. When the Saw Blade is pinched
or bound tightly by the kerf closing down, the Saw Blade stalls and the Motor

reaction drives the tool rapidly toward the operator. If the Saw Blade becomes
twisted or misaligned in the cut, the teeth at the back edge of the Saw Blade can
dig into the top surface of the workpiece, causing the Saw Blade to climb out of
the kerf and jump toward the operator. Kickback is a result of tool misuse and/
or incorrect operating procedures or conditions and can be minimized by
taking proper precautions as given below:
A. Maintain a firm grip with both hands on the Saw, and position your body
and arm to allow you to resist kickback forces.
B. When the Saw Blade is binding, or when interrupting a cut for any rea-
son, release the Power Switch and hold the Saw motionless in the work-
piece until the Saw Blade comes to a complete stop. Never attempt to
remove the Saw from the workpiece or pull the Saw backward while the Saw
Blade is in motion or kickback can occur.
C. When restarting the Saw in the workpiece, center the Saw Blade in the
kerf and check that the saw teeth are not engaged into the workpiece. If
the Saw Blade is binding, it may walk up or kickback from the workpiece as
the Saw is restarted.
D. Support large panels to minimize the risk of Saw Blade pinching and
kickback. Large panels tend to sag under their own weight. Supports must
be placed under the panel on both sides, near the line of cut and near the
edge of the panel.
E. Do not use a dull or damaged Saw Blade. Unsharpened or improperly set
Saw Blades produce a narrow kerf causing excessive friction, Saw Blade
binding and kickback.
F. Make sure all Saw adjustments are tight and secure before making a cut.
If Saw adjustments shift while cutting, it may cause binding and kickback.
14.
15.
WARNING! The Lock Pin (128) should always be activated in the
“locked down” position when the Saw is not being used and when the Saw
is being transported. The Lock Pin should be activated in the “locked up”
position when changing Saw Blades. NEVER use the Lock Pin in any cut-
ting operation. The Lock Pin allows the operator to lock the Saw Blade in
position, preventing the Saw Blade from being raised or lowered.
Allow the Saw Blade to spin up to full speed before feeding it into the
workpiece. Do not force the Saw Blade into the workpiece when cutting. Apply
moderate pressure, allowing the Saw Blade to cut without being forced. When
turning off the Saw, allow the Saw Blade to spin down and stop on its own. Do
not press against the Saw Blade to stop it.
16.
17.
Turn off the Saw and allow the Saw Blade to stop on its own if the Saw
Blade is to be backed out of an uncompleted cut.
Industrial applications must follow OSHA requirements.

The Laser on the Miter Saw is rated as a Class 2. Do not stare directly at the
Laser beam. A hazard may exist if you deliberately stare into the beam. Never
aim the Laser beam at any person, animal, or an object other than the work-
piece.
Make sure the Laser beam is aimed at a sturdy workpiece without reflective
surfaces. Reflective surfaces are not suitable for Laser applications, as the
reflective surface may direct the Laser beam back at the operator, causing poten-
tial eye damage.
20.
21.
22.
Do not attempt to alter the Laser or replace it with a different type. Doing so
may result in hazardous radiation exposure.
Never attempt to remove material stuck in the moving parts of the Miter
Saw while the machine is plugged in and running.
Whenever possible, use clamps or other safe, practical ways to hold and
support the workpiece. Do not attempt to cut material that does not have a flat
surface, unless a suitable support is used.
23.

WARNING! People with pacemakers should consult their physician(s) before
using this product. Operation of electrical equipment in close proximity to a
heart pacemaker could cause interference to or failure of the pacemaker.
WARNING! Some dust created by power sanding, sawing, grinding, drilling,
and other construction activities, contain chemicals known (to the State of Califor-
nia) 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 fromchemically
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. (Califor-
nia Health & Safety Code 25249.5, et seq.)
31.
WARNING! The warnings, precautions, and instructions discussed in this
manual cannot cover all possible conditions and situations that may occur. The
operator must understand that common sense and caution are factors which
cannot be built into this product, but must be supplied by the operator.
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.
GROUNDEDTOOLS:TOOLSWITH THREE PRONG PLUGS
1.
2.
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 elec-
tric shock. (See Figure A.)
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
DOUBLE INSULATED TOOLS:TOOLS WITH TWO PRONG PLUGS
4.
5.
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.)
Double insulated tools may be used in either of the 120 volt outlets shown in the
following illustration. (See Figure B.)

EXTENSION CORDS
1.
2.
Double Insulated tools can use either a two or three wire extension cord.
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)
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.
5.
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)
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 Figure C)
6.
7.
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.
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.

(STOP PLATE) To Adjust The Cutting Depth:
1.
WARNING! Prior to performing this procedure, make sure the Power
Cord (27) of the Miter Saw is unplugged from its electrical outlet.
2.
3.
The depth of cut may be adjusted to a maximum of 4” at 90°, and 1-15/16” at 45°.
Loosen the Wing Screw (103) and pull the Miter Saw’s Motor Housing (31) for-
ward as far as it will go. Notice whether the edge of the Saw Blade (4) passes
completely through the Kerf Board (151). (See Figure P, next page)
4.
5.
If the Saw Blade (4) does not pass completely through the Kerf Board (151),
lower the Saw Blade slightly by turning the two Bolts (133A,133B) counterclock-
wise. (See Figure P)
The rear Short Bolt (133A) should be adjusted for maximum allowable depth of cut.
The forward Long Bolt (133B) is used in conjunction with the Arm Stop Plate (135).
The Long Bolt (133B) can be adjusted for a secondary, less deep cut, if desired.
Pivot the Arm Stop Plate (135) outward to use the front stop, or push the Arm Stop
Plate (135) inward, and the Long Bolt (133B) will bypass it, allowing full depth
of cut. After making the adjustments to the two Bolts (133A, 133B), tighten the two
Jam nuts (159) to keep the two Bolts (133A, 133B) from moving. (See Photo Above)
6.
After adjusting the two Bolts (133A,133B), press down on the Miter
Saw and make sure the Saw Blade (4) does not contact the bottom of the Work
Table (87) or any other part of the Saw Base. (See Figure P)

Plug the Power Cord into the nearest 120 volt, grounded, electrical outlet.
Depress the Safety Button (37) with your thumb, and squeeze the Switch Lever
(41). Then, release the Safety Button.
8.
When the Saw Blade (4) is turning at full speed, slowly bring down the Motor
Housing (31) to complete the cut. NOTE: Feed the Saw Blade into the work-
piece gradually. Do not force the machine to remove material faster than it was
designed to cut.
9.
When cutting a large workpiece, make sure its entire length is properly sup-
ported. If necessary, use a roller stand (not included) with a larger workpiece.
10.
Never attempt to remove material stuck in the moving parts of the Miter Saw
while it is plugged in and running.
11.
12.
Turn off the Miter Saw if the workpiece is to be backed out of an uncompleted cut.
When the cut is complete, release the Switch Lever (41). This allows the Safety
Button (37) to return to the “OFF” position.
13.
14.
15.
Wait until the Saw Blade (4) comes to a complete stop. Then, raise the Motor
Housing (31) to its full “UP” position.
Loosen the Clamp Assembly (96, 99, 109, 111), and remove the workpiece and
scrap material from the Work Table (87).
Unplug the Power Cord (27) from its electrical outlet.
INSPECTION, MAINTENANCE, AND CLEANING
1.
2.
WARNING! Always make sure the Switch Lever (41) is in its “OFF”
position, and unplug the Power Cord (27) from its 120 volt electrical outlet
before performing any inspection, adjustments, maintenance, or cleaning.
Before each use, inspect the general condition of the Miter Saw. Check for
loose screws, misalignment or binding of moving parts, cracked or broken parts,
damaged electrical wiring, loose, cracked, or bent Saw Blade (4), and any other
condition that may affect its safe operation. If abnormal noise or vibration occurs,
have the problem corrected before further use.
Do not use damaged equipment.

Daily: With a soft brush, cloth, or vacuum, remove all dust and debris from the
Miter Saw. Then, use a premium quality, lightweight machine oil to lubricate
all moving parts except the Saw Blade (4).
To replace the Motor Carbon Brushes: It may become necessary at some-
time to replace the two Carbon Brushes (26) when the Motor performance de-
creases, or stops working completely. The Carbon Brushes are located on
each side of the Motor Housing (31). To do so, remove the two Brush Holder
Caps (23). Then, remove the two Carbon Brushes from the Brush Holders (25).
If the Carbon Brushes are worn down more than 1/2, replace both Carbon
Brushes. If, however, the Carbon Brushes are just dirty they may be cleaned by
rubbing them with a pencil eraser. When installing the Carbon Brushes, make
sure the carbon portion of the Carbon Brushes contact the Motor Armature, and
that the springs face away from the Motor. Also, make sure the springs operate
freely. After cleaning or replacement, replace the Brush Holders.
NOTE: New Carbon Brushes tend to arc or spark when first used until they
wear and conform to the Motor’s Armature. (See Assy. Diagram.)
5.
NOTE: With the exceptions of Steps #1, #2, #3, and #4 all other mainte-
nance and servicing should be performed only by a qualified service tech-
nician.
