SAFETYOPERATIONMAINTENANCE SETUP
Electrical Safety
1. Power tool plugs must match the outlet.
Never modify the plug in any way.
Do not use any adapter plugs with grounded
power tools. Unmodified plugs and matching
outlets will reduce risk of electric shock.
2. 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.
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. Safety 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/trigger 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
these devices 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 it is plugged
into an electrical outlet. Turn off the tool, and
unplug it from its electrical outlet before leaving.
11. This product is not a toy.
Keep it out of reach of children.
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.
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.
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.

SAFETY OPERATION MAINTENANCESETUP
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/trigger
does not turn it on and off.
Any power tool that cannot be controlled with the
switch/trigger is dangerous and must be repaired.
3. Disconnect the plug from the power source
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. 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.
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.
Cut-Off Machine Safety Warnings
1. The guard provided with the tool must be
securely attached to the power tool and
positioned for maximum safety, so the least
amount of wheel is exposed towards the
operator. Position yourself and bystanders
away from the plane of the rotating wheel. The
guard helps to protect operator from broken wheel
fragments and accidental contact with wheel.
2. Use only bonded reinforced or diamond
cut-off wheels for your power tool. Just
because an accessory can be attached to your
power tool, it does not assure safe operation.
3. The rated speed of the accessory must be at
least equal to the maximum speed marked
on the power tool. Accessories running faster
than their rated speed can break and fly apart.
4. Wheels must be used only for recommended
applications. For example: do not grind with
the side of cut-off wheel. Abrasive cut-off wheels
are intended for peripheral grinding, side forces
applied to these wheels may cause them to shatter.
5. Always use undamaged wheel flanges that
are of correct diameter for your selected
wheel. Proper wheel flanges support the wheel
thus reducing the possibility of wheel breakage.
6. Do not use worn down reinforced wheels
from larger power tools. Wheels intended
for a larger power tool are not suitable for the
higher speed of a smaller tool and may burst.
7. The outside diameter and the thickness of your
accessory must be within the capacity rating
of your power tool. Incorrectly sized accessories
cannot be adequately guarded or controlled.
8. The arbour size of wheels and flanges
must properly fit the spindle of the power
tool. Wheels and flanges with arbour holes
that do not match the mounting hardware of
the power tool will run out of balance, vibrate
excessively and may cause loss of control.
9. Do not use damaged wheels. Before each use,
inspect the wheels for chips and cracks. If power
tool or wheel is dropped, inspect for damage or
install an undamaged wheel. After inspecting
and installing the wheel, position yourself and
bystanders away from the plane of the rotating
wheel and run the power tool at maximum no
load speed for one minute. Damaged wheels
will normally break apart during this test time.
Page 5For technical questions, please call 1-888-866-5797.Item 59248
SAFETYOPERATIONMAINTENANCE SETUP
10. Wear personal protective equipment. Depending
on application, use face shield, safety goggles
or safety glasses. As appropriate, wear dust
mask, hearing protectors, gloves and shop
apron capable of stopping small abrasive or
workpiece fragments. The eye protection must
be capable of stopping flying debris generated by
various operations. The dust mask or respirator
must be capable of filtrating particles generated
by your operation. Prolonged exposure to high
intensity noise may cause hearing loss.
11. Keep bystanders a safe distance away from
work area. Anyone entering the work area must
wear personal protective equipment. Fragments
of workpiece or of a broken wheel may fly away and
cause injury beyond immediate area of operation.
12. Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact hidden
wiring. Cutting accessory contacting a “live” wire
may make exposed metal parts of the power tool
“live” and could give the operator an electric shock.
13. Never lay the power tool down until the
accessory has come to a complete stop.
The spinning wheel may grab the surface
and pull the power tool out of your control.
14. Do not run the power tool while carrying
it at your side. Accidental contact with the
spinning accessory could snag your clothing,
pulling the accessory into your body.
15. Regularly clean the power tool’s air vents.
The motor’s fan will draw the dust inside
the housing and excessive accumulation of
powdered metal may cause electrical hazards.
16. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
17. Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.

SAFETY OPERATION MAINTENANCESETUP
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or
snagged rotating wheel. Pinching or snagging
causes rapid stalling of the rotating wheel
which in turn causes the uncontrolled power
tool to be forced in the direction opposite of the
wheel’s rotation at the point of the binding.
For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel
that is entering into the pinch point can dig into the
surface of the material causing the wheel to climb
out or kick out. The wheel may either jump toward or
away from the operator, depending on direction of the
wheel’s movement at the point of pinching. Abrasive
wheels may also break under these conditions.
Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and can be
avoided by taking proper precautions as given below.
1. Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. Always use auxiliary
handle, if provided, for maximum control over
kickback or torque reaction during start-up.
The operator can control torque reactions or
kickback forces, if proper precautions are taken.
2. Never place your hand near the
rotating accessory. Accessory
may kickback over your hand.
3. Do not position your body in line with
the rotating wheel. Kickback will propel
the tool in direction opposite to the wheel’s
movement at the point of snagging.
4. Use special care when working corners, sharp
edges etc. Avoid bouncing and snagging the
accessory. Comers, sharp edges or bouncing
have a tendency to snag the rotating accessory
and cause loss of control or kickback.
5. Do not attach a saw chain, woodcarving blade,
segmented diamond wheel with a peripheral gap
greater than 10mm or toothed saw blade. Such
blades create frequent kickback and loss of control.
6. Do not “jam” the wheel or apply excessive
pressure. Do not attempt to make an
excessive depth of cut. Overstressing the
wheel increases the loading and susceptibility
to twisting or binding of the wheel in the cut and
the possibility of kickback or wheel breakage.
7. When wheel is binding or when interrupting
a cut for any reason, switch off the power
tool and hold the power tool motionless until
the wheel comes to a complete stop. Never
attempt to remove the wheel from the cut while
the wheel is in motion otherwise kickback
may occur. Investigate and take corrective
action to eliminate the cause of wheel binding.
8. Do not restart the cutting operation in
the workpiece. Let the wheel reach full
speed and carefully re-enter the cut. The
wheel may bind, walk up or kickback if the
power tool is restarted in the workpiece.
9. Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag under
their own weight. Supports must be placed under
the workpiece near the line of cut and near the
edge of the workpiece on both sides of the wheel.
10. Use extra caution when making a “pocket cut”
into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes,
electrical wiring or objects that can cause kickback.

SAFETYOPERATIONMAINTENANCE SETUP
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:
1. 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.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
3. Wear suitable gloves to reduce the
vibration effects on the user.
4. Use tools with the lowest vibration when there
is a choice between different processes.
5. Include vibration-free periods each day of work.
6. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.
7. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.
SAVE THESE INSTRUCTIONS.

SAFETY OPERATION MAINTENANCESETUP
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 Outlets for 2-Prong Plug.)
Page 9For technical questions, please call 1-888-866-5797.Item 59248
SAFETYOPERATIONMAINTENANCE SETUP
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.
