IMPORTANT SAFETY INFORMATION
GENERAL POWER TOOL SAFETY WARNINGS
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions 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.
Work area safety
1. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
2. 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.
3. Keep children and bystanders
away while operating a power tool.
Distractions can cause you to lose control.
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. Protective 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 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
dust collection 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. Avoid unintentional starting.
Prepare to begin work before turning on the tool.
11. 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.
12. When using a handheld power tool,
maintain a firm grip on the tool with both
hands to resist starting torque.

Item 56845
13. 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.
14. Wear steel‑toed boots during use.
15. Do not operate this tool if you have back, neck,
or wrist injuries, or other conditions that will
be aggravated by the severe jerking forces
that this tool exerts upon the operator.
16. This product is not a toy. Keep it
out of reach of children.
17. 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.
18. 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 Trigger
does not turn it on and off. Any power tool
that cannot be controlled with the Trigger
is dangerous and must be repaired.
3. 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.
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.
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. Maintain labels and nameplates on the tool.
These carry important safety information.
If unreadable or missing, contact
Harbor Freight Tools for a replacement.
Safety instructions for all operations
1. Wear ear protectors. Exposure to
noise can cause hearing loss.
2. Use auxiliary handle(s) if supplied with the
tool. Loss of control can cause personal injury.
3. 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.
4. 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.
5. Let bit cool before touching, changing
or adjusting it. Bits heat up dramatically
while in use, and can burn you.
6. If the drill bit jams, release the Trigger immediately;
drill torque can cause injury or break bit.
Safety Instructions when using
long drill bits with rotary hammers
1. 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.
2. 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.

Item 56845
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).Silicosis Safety Measures.
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.
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.
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.
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.)

Item 56845
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 following 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.
