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 corded 14” Cut Off Saw.
SAVE THESE INSTRUCTIONS
Work area safety1.
Keep work area clean and well lit. a. Cluttered or dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the b.
presence of ammable liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
Keep children and bystanders away while operating a power tool. c.
Distractions can cause you to lose control.
Electrical safety2.
Power tool plugs must match the outlet. Never modify the plug in any way. a.
Do not use any adapter plugs with grounded power tools. Unmodied plugs
and matching outlets will reduce risk of electric shock.
Avoid body contact with grounded surfaces such as pipes, radiators, ranges b.
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. c. Water entering a
power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord for carrying, pulling or d.
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.
When operating a power tool outdoors, use an extension cord suitable for e.
outdoor use. Use of a cord suitable for outdoor use reduces the risk of
electric shock.
Personal safety3.
Stay alert, watch what you are doing and use common sense when operating a.
a power tool. Do not use a power tool while you are tired or under the
inuence of drugs, alcohol or medication. A moment of inattention while
operating power tools may result in serious personal injury.
Use safety equipment. Always wear eye protection. b. Safety equipment
such as dust mask, full face shield, non-skid safety shoes, work gloves,
or hearing protection used for appropriate conditions will reduce
personal injuries.
Page 4SKU 96971 For technical questions, please call 1-800-444-3353.
Avoid accidental starting. Ensure the switch is in the off position before c.
plugging in. Plugging in power tools with the power switch on, invites
accidents.
Remove any adjusting key or wrench before turning the power tool on. d. A
wrench or a key 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. e. This
enables better control of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewelry. Keep your hair, f.
clothing and gloves away from moving parts. Loose clothes, jewelry or long
hair can be caught in moving parts.
If devices are provided for the connection of dust extraction and collection g.
facilities, ensure these are connected and properly used. Use of these
devices can reduce dust-related hazards.
Power tool use and care4.
Do not force the power tool. Use the correct power tool for your application. a.
The correct power tool will do the job better and safer at the rate for which it
was designed.
Do not use the power tool if the switch does not turn it on and off. b. Any power
tool that cannot be controlled with the switch is dangerous and must be
repaired.
Disconnect the plug from the power source before making any c.
adjustments, changing accessories, or storing power tools. Such
preventive safety measures reduce the risk of starting the power tool
accidentally.
Store idle power tools out of the reach of children and do not allow d.
persons unfamiliar with the power tool or these instructions to operate
the power tool. Power tools are dangerous in the hands of untrained
users.
Maintain power tools. Check for misalignment or binding of moving parts, e.
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.
Keep cutting tools sharp and clean. f. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
Use the power tool, accessories and tool bits etc., in accordance with these g.
instructions and in the manner intended for the particular type of power tool,
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

Service5.
Have your power tool serviced by a qualied repair person using only a.
identical replacement parts. This will ensure that the safety of the power tool
is maintained.
VIBRATION HAZARD
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:
Anyone using vibrating tools regularly or for an extended period should rst 1.
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 ngers), seek medical advice as soon as
possible.
Do not smoke during use. Nicotine reduces the blood supply to the hands and 2.
ngers, increasing the risk of vibration-related injury.
Wear suitable gloves to reduce the vibration effects on the user.3.
Use tools with the lowest vibration when there is a choice between different 4.
processes.
Include vibration-free periods each day of work.5.
Grip tool as lightly as possible (while still keeping safe control of it). Let the tool 6.
do the work.
To reduce vibration, maintain the tool as explained in this manual. If any 7.
abnormal vibration occurs, stop use immediately.
SPECIFIC SAFETY RULES
Maintain labels and nameplates on the tool. These carry important safety 1.
information. If unreadable or missing, contact Harbor Freight Tools for a
replacement.
Avoid unintentional starting. Prepare to begin work before turning on the tool.2.
Do not use without guards in place. Do not remove the safety chain.3.
For industrial use, handle, mount, and operate in accordance with ANSI Safety 4.
Code B7.1 and OSHA rules.
Page 6SKU 96971 For technical questions, please call 1-800-444-3353.
Examine before and after installation and before use for cracks, breaks, nicks, 5.
or fractures. If any exist, do not use; the Cutting Wheel could shatter, causing
serious injury and/or property damage. Discard if dropped, struck with hard
surface, or exposed to moisture.
Straight cut only; never bend the Cutting Wheel. Do not grind on side of the 6.
Cutting Wheel.
Always use Cutting Wheels with a 14” diameter, 1” Spindle, and rated at a 7.
minimum of 3,900 RPM. Cutting Wheels that do not match the mounting
hardware of the Saw or that are rated at less than the Saw’s maximum RPM may
y off the Saw or may run poorly, causing loss of control.
For metal cutting use only. Do not use to cut wood, masonry, magnesium, plastic 8.
or any other non-ferrous material. Never mount any Cutting Wheel not intended
for metal cutting.
Do not stand in line of Cutting Wheel when machine is started. 9.
Run Cutting Wheel at full speed for one minute before use. After turning off the 10.
Saw, allow the Cutting Wheel to spin down and stop on its own.
The Cutting Wheel and stock will become hot while cutting. Do not touch Cutting 11.
Wheel or stock immediately after cutting. Allow both to air cool before handling.
Do not exceed the maximum 4” cutting capacity. 12.
Check Swing Guard for proper closing before each use. Do not operate the Saw 13.
if the Swing Guard does not move freely and close instantly. Never clamp or tie
the Swing Guard into the open position.
Do not leave the tool unattended when it is plugged into an electrical outlet. Turn 14.
off the tool, and unplug it from its electrical outlet before leaving.
Use the built-in clamp or other practical ways to secure and support the 15.
workpiece to a stable platform. Holding the work by hand or against your body is
unstable and may lead to loss of control.
This product is not a toy. Keep it out of reach of children.16.
People with pacemakers should consult their physician(s) before use. 17.
Electromagnetic elds 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 power switch locked on.
• Properly maintain and inspect to avoid electrical shock.
• Any power cord must be properly grounded. Ground Fault Circuit Interrupter
(GFCI) should also be implemented – it prevents sustained electrical shock.

Some dust created by power sanding, sawing, grinding, drilling, and other 18.
construction activities, contains 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 instruction manual 19.
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.
SAVE THESE INSTRUCTIONS.
GROUNDING
Improperly connecting the grounding wire can result in
electric shock.
Check with a qualied 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 qualied
electrician.
Grounded Tools: Tools with Three Prong Plugs
Tools marked with “Grounding Required” have a three wire cord and three prong 1.
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 2.
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.)
WARNING
Page 8SKU 96971 For technical questions, please call 1-800-444-3353.
The tool must be plugged into an appropriate outlet, properly installed and 3.
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.)
3-Prong Plug and Outlet
Outlets for 2-Prong Plug
Double Insulated Tools: Tools with Two Prong Plugs
Tools marked “Double Insulated” do not require grounding. They have a special 1.
double insulation system which satises OSHA requirements and complies
with the applicable standards of Underwriters Laboratories, Inc., the Canadian
Standard Association, and the National Electrical Code.
(See Outlets for 2-Prong Plug.)
Double insulated tools may be used in either of the 120 volt outlets shown in the 2.
preceding illustration. (See Outlets for 2-Prong Plug.)
Extension Cords
Grounded1. 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 2.
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.)
The smaller the gauge number of the wire, the greater the capacity of the cord. 3.
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 4.
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 nameplate5.
amperes and use the sum to determine the required minimum cord size.
(See Table A.)
Page 9SKU 96971 For technical questions, please call 1-800-444-3353.
If you are using an extension cord outdoors, make sure it is marked with the 6.
sufx “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. 7.
Always replace a damaged extension cord or have it repaired by a qualied
electrician before using it.
Protect the extension cords from sharp objects, excessive heat, and damp or wet 8.
areas.

SAFETY
■PRACTICAL TIPS
◆ Before assembling or disassembling the cutting wheel, do confirm the machine is under switch off
condition, and the plug is drawn out. The maximum circumferential velocity of the cutting wheel
shall not less than 4800m/min. The maximum diameter of the cutting wheel shall not more than
355mm.
◆ Do confirm the hexagonal bolt is screwed tightly, if it is not screwed tightly enough, it's possible
to cause injur
y accidents. Use the attached wrench to ensure the bolts are screwed tightly.
◆ Use the abovemention ed big interspace setti ngs to cut narrow objec ts; the safety fixing
performance is inferior.
◆ When setting the graduation plate under the cutting condition of 35-205MM (1 3/8 inch-8 11/16
inch) or 70-240MM (2 3/4 inch-9 7/16 inch), it can't be cut in bevel angle.
◆ At the time of fixing the object, do remember to press the fast nut in right turn enough, if don't
make such operatio
n, the object can't be clamped enough, thus the object will be cracked or the
cutting wheel will be damaged.
◆ The sparks turns out from cutting decides the pressure applies on the handle is suitable or not, and
if it has attained best efficiency of cutting or not. Applied pressure on the handle shall be adjusted to
the maximum extend to evolve sparks, don't press the handle overmuch, otherwise, it'll decrease the
cutting efficiency, wear the cutting wheel untimely, and it's po
ssible to make the machine, cutting
wheel and object damaged.
■
MAINTENANCE AND CARE
.
Unplug the tool from the socket before performing any works on the tool!
.

◆ Assemble or Disassemble the Cutting Wheel
Press the self-locking peg to make the cutting
wheel can't rotate, release the hexagonal bolt with
wrench COUNTER CLOCKWISE, and then
disassemble the hexagonal bolt, upper pressure
plate and cutting wheel.
When assembling the cutting wheel, the steps are
opposite to the above-said steps (Picture One,
Picture Two, Picture Three).
◆ Caution: To confirm the hexagonal bolt be
screwed dow
n. If the hexagonal bolt don't screw
down, it will lead to accidents. Use the spanner
with machine to tweak.
◆ Spark Shield
The spark shield is equipped on the forepart of
base plate. Before operation, please release the
screws to adjust the angle of the spark shield
according to the operating requirements to avoid
spattering the sparks everywhere (Picture Four).
◆ Fixing Project
Wrench the silk rod shank COUNTER
CLOCKWISE to release the object, press the fast
nut in left turn
, at this time, the silk rod shank can
be pull out or push in rapidly. At the time of
clamping the object, push the silk rod shank in
until the pliers plate touches the object; press the
fast nut in right turn, and then rotate the silk rod
shank CLOCKWISE to clamp the object tightly
(Picture Seven).
When cutting long object, put two nonflammable
cushions under two ends of it, and make the
object to keep in level with the pan base, ensure
the supporting plain of the two cushions an the
sup
porting plain of the base plate in a straight line
(Picture Ten).
Press the switch trigger of the machine, it switches
on; loose the trigger completely, the machine is
under switch off condition. (Picture Eleven)
◆ Carrying of the Machine
Hang the chain to the hook of the handle (Picture
Twelve).
◆ Cutting Ability
The maximum cutting ability is different according to the angles of cutting and the shape of the objects.
◆ Replace the Electric Brush
Replace and inspect the carbon
brush periodically.
When the machine appears big sparks or doesn't
rotate, if the carbon brush is worn and less than
5MM, it needs to be replaced. Please keep it clean
and make it slides freely in holding brush. Please
replace two brushes at the same time, and use the
specified "KEN" brand electric brush.
Please use screwdriver to screw the lid of the
holding brush, take out the wearing carbon brush
and insert the new ones, and then screw the lid of
holding brush tightly (Picture T
hirteen).
◆ Operation
Hold the handle firmly, start up the machine until the cutting wheels reach enough rotational
speed and then press the cutting wheel slowly. When the cutting wheel touches the object, press
the handle sustained, apply cutting operation. When the cutting finishes, switch off the machine
firstly until the cutting wheel stops rotation completely, and then lift the handle to enough high
position.
When the cutting wheel is worn out greatly, put a
nonflam
mable hard cushion under the back of the
object, thus it can use the middle edge of the
cutting wheel to cut the object efficiently (Picture
Eight).
If puts a cushion which is narrower than the object
under the object, the cutting wheel will be used
more economically and efficiently (Picture Nine).
◆Limitative bolt
'Thelimitative bolt can prevent the cutting wheel
from touching the table or ground. To adjust the
height of bolt can regulate the area of cutting. It
can adjust th
e bolt t o increase cutting capability
when cutting wheel is attrite. (Picture Five).
◆ The Interspaces Between the Pliers Plate
and Graduation Plate
The fixed distance is 0-170MM (0-6 11/16 inch)
between pliers plate and graduation plate, if
needing wider interspaces, please adjust the
interspaces according to the undermentioned
procedures.
Discharge two hexagonal bolts of the fixed
graduation plate, move it like the picture stated,
after that, fix the hexagonal bol
t. According to the
adjusting step, it can attain the undermentioned
interspaces setting range (Picture Six).
35-205 MM (1 3/8 inch-8 11/16 inch)
70-240 MM (2 3/4 inch-9 7/16 inch)
◆ Setting of Cutting Angle
Release two hexagonal bolts on the fixed
graduation plate. Move the graduation plate to the
intended cutting angle (0-45¡ã), and screw the
hexagonal bolts tightly. Thus it can set the cutting
angle (Picture Six).
