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.
1. Work area safety
a. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b. 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.
c. Keep children and bystanders away
while operating a power tool. Distractions
can cause you to lose control.
2. Electrical safety
a. 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.
b. 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.
c. Do not expose power tools to rain or wet
conditions. Water entering a power tool
will increase the risk of electric shock.
d. 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.
e. 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.
f. 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.
3. Personal safety
a. 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.
b. 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.
c. 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.
d. 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.
e. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
f. 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.
g. 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.
h. 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.
i. 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.
j. Avoid unintentional starting.
Prepare to begin work before turning on the tool.
k. Do not depress the spindle lock when
starting or during operation.
l. 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.
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.
o. 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.
4. Power tool use and care
a. 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.
b. 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.
c. 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.
d. 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.
e. 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.
f. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
g. 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.
h. 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.
5. Service
a. 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.
b. Maintain labels and nameplates on the tool.
These carry important safety information.
If unreadable or missing, contact
Harbor Freight Tools for a replacement.
6. Cut-off machine safety warnings
a. Position yourself and bystanders away from
the plane of the rotating wheel. The guard
helps to protect the operator from broken wheel
fragments and accidental contact with wheel.
b. Use only bonded reinforced wheels
for your power tool. Just because an
accessory can be attached to your power
tool, it does not assure safe operation.
c. 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.
d. Wheels must be used only for recommended
applications. For example: do not grind
with the side of a cut-off wheel. Abrasive
cut-off wheels are intended for peripheral
grinding, side forces applied to these
wheels may cause them to shatter.
e. Always use undamaged wheel flanges that
are of correct diameter for your selected
wheel. Proper wheel flanges supporl the wheel
thus reducing the possibility of wheel breakage.
f. 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.
g. The arbour size of wheels and flanges
must properly flt 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.
h. Do not use damaged wheels. Before each
use, Inspect the wheels for chips and cracks.
If the 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
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.
j. 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.
k. Position the cord clear of the spinning
accessory. If you lose control, the cord may
be cut or snagged and your hand or arm
may be pulled into the spinning wheel.
l. Regularly clean the power tool’s air vents.
The motor’s fan can draw the dust inside
the housing and excessive accumulation of
powdered metal may cause electrical hazards.
m. Do not operate the power tool near flammable
materials. Do not operate the power tool
while placed on a combustible surface such
as wood. Sparks could ignite these materials.
n. Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
7. 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 cutting unit to
be forced upwards toward the operator.
- 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. 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.
a. Maintain a firm grip on the power tool
and position your body and arm to
allow you to resist kickback forces. The
operator can control upward kickback
forces, if proper precautions are taken.
b. Do not position your body in line with the
rotating wheel. If kickback occurs, it will propel
the cutting unit upwards toward the operator.
c. Do not attach a saw chain, woodcarving
blade, segmented diamond wheel with
a peripheral gap greater than 10 mm or
toothed saw blade. Such blades create
frequent kickback and loss of control.
d. 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.
e. When the wheel is binding or when
interrupting a cut for any reason, switch
off the power tool and hold the cutting unit
motionless in the material until the wheel
comes to a complete stop. Never attempt
to remove the wheel from the cut while
the wheel is in motion or kickback may
occur. Investigate and take corrective actions
to eliminate the cause of wheel binding.
f. 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.
g. Support any oversized workpiece to minimise
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.
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:
a. 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 symptoms related to vibration (such as
tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
b. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
c. Wear suitable gloves to reduce the
vibration effects on the user.
d. Use tools with the lowest vibration when there
is a choice between different processes.
e. Include vibration-free periods each day of work.
f. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.
g. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.
Grounding Instructions
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.
Double Insulated Tools: Tools with
Two Prong Plugs
1. To reduce the risk of electric shock, double
insulated equipment has 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
the proper outlet. Do not change the plug in any way.
2. Double insulated tools may be used in either of the
120 volt outlets shown in the following illustration.
(See Outlets for 2-Prong Plug.)
Outlets for 2-Prong Plug
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.
