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
is in the off-position before connecting to
power source, 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. 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.
8. 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.
9. Do not lay the tool down until it has come to
a complete stop. Moving parts can grab the
surface and pull the tool out of your control.
10. When using a handheld power tool,
maintain a firm grip on the tool with both
hands to resist starting torque.
11. Do not depress the spindle lock when
starting or during operation.
12. Do not leave the tool unattended when the
Battery Pack is connected. Turn off the tool,
and remove the Battery Pack before leaving.
13. This product is not a toy.
Keep it out of reach of children.
14. 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.
15. 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.
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 does not turn it on and off.
Any power tool that cannot be controlled with
the switch 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.
Page 4 For technical questions, please call 1-888-866-5797. Item 59660
SaFety OperatiOn MaintenanceSetup
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.
8. 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.
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. never service damaged Battery packs. Service
of BATTERY packs should only be performed by
the manufacturer or authorized service providers.
3. 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 arbor size of wheels and flanges
must properly fit the spindle of the power
tool. Wheels and flanges with arbor 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.
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 or its own cord. Cutting
accessory contacting a "live" wire may make
exposed metal parts of the power tool "live" and
could give the operator an electric shock.
Page 5For technical questions, please call 1-888-866-5797.Item 59660
SaFetyOperatiOnMaintenance Setup
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. Verify that there are no utility lines or
hardware in or near the workpiece.
This is especially critical for plunge cuts.
Battery tool use and care
1. prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to battery pack, picking up or carrying the
power tool. Carrying the power tool with your
finger on the switch or energizing power tool
that have the switch on invites accidents.
2. Disconnect the battery pack from the
power tool before making any adjustments,
changing accessories, or storing power tool.
Such preventive safety measures reduce the
risk of starting the power tool accidentally.
3. recharge only with the charger specified by
the manufacturer. A charger that is suitable
for one type of battery pack may create a risk
of fire when used with another battery pack.
4. use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
5. When battery pack is not in use, keep it away
from other metal objects, like paper clips,
coins, keys, nails, screws or other small metal
objects, that can make a connection from
one terminal to another. Shorting the battery
terminals together may cause burns or a fire.
6. under abusive conditions, liquid may be
ejected from the battery; avoid contact.
If contact accidentally occurs, flush with
water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the
battery may cause irritation or burns.
7. Do not use a battery pack or power tool that
is damaged or modified. Damaged or modified
batteries may exhibit unpredictable behavior
resulting in fire, explosion or risk of injury.
8. Do not expose a battery pack or power tool to
fire or excessive temperature. Exposure to fire or
temperature above 140°F may cause explosion.
9. Follow all charging instructions and do
not charge the battery pack or power tool
outside of the temperature range specified
in the instructions. Charging improperly or at
temperatures outside of the specified range may
damage the battery and increase the risk of fire.
10. Have servicing performed by a qualified
repair person using only identical
replacement parts. This will ensure that
the safety of the product is maintained.
11. Do not modify or attempt to repair the power
tool or the battery pack except as indicated
in the instructions for use and care.
12. The battery Charger gets hot during use.
The Charger’s heat can build up to
unsafe levels and create a fire hazard if it
does not receive adequate ventilation,
due to an electrical fault, or if it is used in a
hot environment. Do not place the Charger on a
flammable surface. Do not obstruct any vents on
the Charger. especially avoid placing the
charger on carpets and rugs; they are not only
flammable, but they also obstruct vents under
the charger. Place the Charger on a stable, solid,
nonflammable surface (such as a stable metal
workbench or concrete floor) at least 1 foot away
from all flammable objects, such as drapes or walls.
Keep a fire extinguisher and a smoke detector in the
area. Frequently monitor the Charger and
Battery Pack while charging.

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. Corners, 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.
Page 7For technical questions, please call 1-888-866-5797.Item 59660
SaFetyOperatiOnMaintenance Setup
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.
Silicosis Safety Measures
Masonry drilling on materials such as concrete (which
contains crystalline silica) can cause silicosis (a serious
lung disease), cancer and death. To reduce
crystalline silica exposures in the workplace and
prevent silicosis and silicosis‑related deaths:
1. Conduct air monitoring to measure
worker exposures.
2. Use containment methods to control the hazard
and protect adjacent workers from exposure.
3. Practice good personal hygiene to avoid
unnecessary exposure to silica dust.
4. Wear washable or disposable protective
clothes at the work site. Shower and change
into clean clothes before leaving the work site
to prevent contamination of cars, homes and
other work areas. Avoid skin exposure.
5. Always wear a NIOSH approved respirator and
safety goggles. Ventilate the work area properly.
6. Provide periodic medical examinations for all
workers who may be exposed to crystalline silica.
7. Post signs to warn workers about the hazard and to
inform them about required protective equipment.
8. Provide workers with training that includes
information about health effects, work practices
and protective equipment for crystalline silica.
9. Report all cases of silicosis to State health
departments and to OSHA or the Mine Safety
and Health Administration (MSHA).
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 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.
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.
