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.

SAFETYOPERATIONMAINTENANCE SETUP
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 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.
l. When using a handheld power tool,
maintain a firm grip on the tool with
both hands to resist starting torque.
m. 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.
n. This product is not a toy.
Keep it out of reach of children.
o. 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.
p. 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
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. Safety instructions for all operations
a. Wear ear protectors when Impact drilling.
Exposure to noise can cause hearing loss.
b. Use the auxiliary handle(s). Loss of
control can cause personal injury.
c. Brace the tool properly before use. This
tool produces a high output torque and without
properly bracing the tool during operation, loss
of control may occur resulting in personal injury.
d. Hold the power tool by insulated gripping
surfaces, when performing an operation
where the cutting accessory or fasteners
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.
e. Let bit cool before touching, changing
or adjusting it. Bits heat up dramatically
while in use, and can burn you.
f. If the drill bit jams, release the
Trigger immediately; drill torque
can cause injury or break bit.
7. Safety Instructions when using long drill bits
a. Never operate at higher speed than the
maximum speed rating of the drill bit.
At higher speeds, the bit is likely to bend if
allowed to rotate freely without contacting
the workpiece, resulting in personal injury.
b. Always start drilling at low speed and with
the bit tip in contact with the workpiece.
At higher speeds, the bit is likely to bend if
allowed to rotate freely without contacting
the workpiece, resulting in personal injury.
c. Apply pressure only in direct line with the
bit and do not apply excessive pressure.
Bits can bend causing breakage or loss
of control, resulting in personal injury.
8. 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:
a. Conduct air monitoring to measure
worker exposures.
b. Use containment methods to control the hazard
and protect adjacent workers from exposure.
c. Practice good personal hygiene to avoid
unnecessary exposure to silica dust.
d. 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.
e. Always wear a NIOSH approved respirator and
safety goggles. Ventilate the work area properly.
f. Provide periodic medical examinations for all
workers who may be exposed to crystalline silica.

Page 5For technical questions, please call 1-888-866-5797.Item 58214
SAFETYOPERATIONMAINTENANCE SETUP
g. Post signs to warn workers about
the hazard and to inform them about
required protective equipment.
h. Provide workers with training that includes
information about health effects, work practices
and protective equipment for crystalline silica.
i. Report all cases of silicosis to State health
departments and to OSHA or the Mine
Safety and Health Administration (MSHA).
9. 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.
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
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.)

Page 6 For technical questions, please call 1-888-866-5797. Item 58214
SAFETY OPERATION MAINTENANCESETUP
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.)
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.
