GENERAL SAFETY RULES

WARNING! Read all instructions

Failure to follow all instructions listed below may result in electric shock,

re, and/or serious injury. The term “power tool” in all of the warnings listed

below refers to your line-operated (corded) power tool or battery-operated

(cordless) power tool.

SAVE THESE INSTRUCTIONS

WORK AREA

Keep your work area clean and well lit. Cluttered benches and dark areas

invite accidents.

Do not operate power tools in explosive atmospheres, such as in the

presence of ammable liquids, gases, or dust. Power tools create sparks

which may ignite ammables.

E105017E105017

Rev 07k

Page 3SKU 91995 For technical questions, please call 1-800-444-3353.

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 qualied 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.

Double insulated tools are equipped with a polarized plug (one blade is

wider than the other). This plug will t in a polarized outlet only one way.

If the plug does not t fully in the outlet, reverse the plug. If it still does

not t, contact a qualied 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.

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 Power Cord to carry the tools or

pull Plug from an outlet. Keep the Power Cord away from heat, oil, sharp

edges, or moving parts. Replace damaged Power Cords immediately.

Damaged Power Cords increase the risk of electric shock.

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

Stay alert. Watch what you are doing, and use common sense when

operating a power tool. Do not use a power tool while tired or under the

inuence of drugs, alcohol, or medication. A moment of inattention while

operating 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.

Page 4SKU 91995 For technical questions, please call 1-800-444-3353.

Avoid accidental starting. Be sure the Power Switch is off before plugging

in. Carrying power tools with your nger 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

situations.

Use safety equipment. Always wear ANSI approved safety glasses

underneath a full face shield, a dust mask or respirator, and hearing

protection.

TOOL USE AND CARE

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.

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.

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.

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. Do not use a damaged tool. Tag damaged tools “Do

not use” until repaired.

Check for misalignment or binding of 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

Tool service must be performed only by qualied repair personnel. Service

or maintenance performed by unqualied personnel could result in a risk of injury.

When servicing a tool, use only identical replacement parts. Follow

instructions in the “Inspection, Maintenance, And Cleaning” section of this

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 ammable chemicals, dusts, and vapors. Do not use this product in a

damp or wet location.

Maintain labels and nameplates on the Miter Saw. These carry important

information. If unreadable or missing, contact Harbor Freight Tools for a

replacement.

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.

Keep all guards in place and in working order. Never remove or disable

guards.

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.

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.

When replacing the Saw Blade, make sure the new Saw Blade has a

diameter of 10”, an RPM rating of at least 7000, and has an arbor hole of

5/8” diameter.

To avoid accidental injury, always wear heavy duty work gloves when

changing a Saw Blade.

Page 6SKU 91995 For technical questions, please call 1-800-444-3353.

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.

The Saw Blade will become hot while cutting. Allow the Saw Blade to

completely 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:

Maintain a rm grip with both hands on the Saw, and position your body

and arm to allow you to resist kickback forces.

When the Saw Blade is binding, or when interrupting a cut for any

reason, release the Power Switch and hold the Saw motionless in the

workpiece until the Saw Blade comes to a complete stop. Never attempt

to remove the Saw Blade from the workpiece or pull the Saw backward while

the Saw Blade is in motion or kickback can occur.

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.

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.

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.

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.

The Cross Pin (28) should always be in the “locked down” position when

the Saw is not being used and when the Saw is being transported. The

Cross Pin should be activated in the “locked up” position when changing

Saw Blades. NEVER use the Cross Pin in any cutting operation. The Cross

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.

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.

Proper Miter Saw location: Make sure the Miter Saw is located on a at, level,

sturdy surface capable of supporting the weight of the Miter Saw, workpieces,

and all other tools and accessories.

Do not abuse the Power Cord. Do not use the Power Cord to pull the Power

Plug from an electrical outlet. Keep the Power Cord away from heat, oil, sharp

edges, and moving parts. Route the Power Cord safely. Do not route the Power

Cord where it can be walked on or tripped over. Replace a damaged Power Cord

immediately.

Keep all safety guards in place, in proper adjustment, and in proper

alignment.

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 at

surface, unless a suitable support is used.

Always keep hands and ngers away from the spinning Saw Blade.

Use eye, hearing, and breathing protection. Always wear ANSI-approved

safety impact eye goggles, hearing protectors, and dust masks or respirator

when working with the Miter Saw.

Do not use this product if under the inuence of alcohol or drugs. Read

warning labels on prescriptions to determine if your judgement or reexes are

impaired while taking drugs. If there is any doubt, do not attempt to use this

product.

electrical outlet before changing accessories or performing inspection,

maintenance, or cleaning procedures.

Keep children out of the work area. Never allow children to play with tools.

Always lock and secure the work area.

People with pacemakers should consult their physician(s) before use.

Electromagnetic elds in close proximity to heart pacemaker could cause

pacemaker interference or pacemaker failure.

WARNING! Some dust created by power sanding, sawing, grinding, drilling, and

other construction activities, contain chemicals known (to the State of California)

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 from

chemically 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 lter out microscopic particles.

(California Health & Safety Code 25249.5, et seq.)

The warnings, precautions, and instructions discussed in this manual cannot

cover all possible conditions and situations that may occur. The operator must

GROUNDING

Improperly connecting the grounding wire can result in

electric shock.

Check with a qualied 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 qualied

electrician.

Grounded Tools: Tools with Three Prong Plugs

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.)

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.)

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 following illustration.

(See 3-Prong Plug and Outlet.)

Extension Cords

Grounded 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 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.)

WARNINGWARNING

3-Prong Plug and Outlet3-Prong Plug and Outlet

Page 10SKU 91995 For technical questions, please call 1-800-444-3353.

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.)

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.)

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.)

If you are using an extension cord outdoors, make sure it is marked with the

sufx “W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.

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 qualied

electrician before using it.

Protect the extension cords from sharp objects, excessive heat, and damp or wet

areas.
