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 andmatching
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 bodyis grounded.
3. Do not expose power tools to rain or wet
conditions. Water entering apowertool
will increase the risk
of electric shock.
Personal safety
1. Stay alert, watch what you are doing
and use common sense when operating
apower tool. Do not use apower
tool while you are tired or under the
influence of drugs, alcohol or medication.
Amoment
of inattention while operating power
tools mayresult in serious personal injury.
2. Use personal protective equipment.
Always wear eye protection. Safety equipment
such as dust mask, non-skid safetyshoes,
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 powertools 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.
Awrench or akey left attached to arotating part
of the powertool may result in personal injury.
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 apower tool outdoors,
use an extension cord suitable for
outdoor use. Use
of acord suitable for outdoor
use reduces the risk
of electric shock.
6. If operating apower tool in adamp location
is unavoidable, use aGround Fault Circuit
Interrupter (GFCI) protected supply.
Use
of aGFCI reduces the risk of electric shock.
5. Do not overreach. Keep proper footing and
balance at all times. This enables bettercontrol
of the powertool 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 haircan 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. Only use safety equipment that has been
approved by an appropriate standards agency.

Rotary Hammer Safety Warnings
1. Wear ear protectors with rotary hammers.
Exposure to noise can cause hearing loss.
2. Use auxiliary handles supplied with the tool.
Loss
of control can cause personal injury.
3. Hold power tools by insulated gripping surfaces
when performing
an operation where the cutting
tool may contact hidden wiring or its own cord.
Contact with a"live" wire will make exposed metal
parts
of the tool "live" andshock the operator.
4. Let bit cool before touching, changing
or adjusting it. Bits heat up dramatically
while in use, and can burn you.
5. If the drill bit jams, release the
trigger immediately; drill torque
can cause injury or break bit.
6. Maintain labels and nameplates on the tool.
These carry important safety information.
If unreadable or missing, contact
Harbor Freight Tools for areplacement.
7. Avoid unintentional starting.
Prepare to begin work before turning on the tool.
8. Do not lay the tool down until it has come to
acomplete stop. Moving parts can grab the
surface and pull the tool out
of your control.
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. Manyaccidents
are caused
by poorlymaintained powertools.
6. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bindand are easierto 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
powertool for operations different from those
intended could result in ahazardous situation.
9. When using ahandheld power tool,

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 power switch locked on.
•Properly maintain and inspect to avoid
electrical shock.
•Any power cord must be properly
grounded. 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,

ASAVE THESE INSTRUCTIONS.
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 adoctor 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 achoice.
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. Ifany abnormal
vibration occurs, stop use immediately.

Grounding
~
TO PREVENT ELECTRIC SHOCK AND DEATH FROM INCORRECT GROUNDING
,., WIRE CONNECTION:
~ Check with aqualified 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 aservice facility before use. If the plug will not fit the outlet, have aproper outlet installed by
aqualified electrician.
Double Insulated Tools: Tools with Two Prong Plugs
Grounded Tools: Tools with Three Prong Plugs
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.)
3-Prong Plug and Outlet
1. Tools marked with "Grounding Required" have
athree wire cord and three prong grounding
plug. The plug must be connected to aproperly
grounded outlet. Ifthe tool should electrically
malfunction or break down, grounding provides
alow resistance path to carry electricity away
from the user, reducing the risk
of electric
shock. (See 3-Prong Plug and Outlet.)
Outlets for 2-Prong Plug
1. Tools marked "Double Insulated" do not
require grounding. They have aspecial
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 6For technical questions, please call 1-888-866-5797. Item 64425

Extension Cords
1. Grounded tools require athree wire extension cord.
Double Insulated tools can use either
atwo or three wire extension cord.
2. As the distance from the supply outlet increases,
you must use aheavier gauge extension cord.
Using extension cords with inadequately sized
wire causes aserious drop
in voltage, resulting
in loss of power and possible tool damage.
(See Table A
on page 7.)
3. The smaller the gauge number of the wire, the
greater the capacity of the cord. For example,
a
14 gauge cord can carry ahigher 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. Ifyou 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
adamaged extension cord or have it repaired
by aqualified electrician before using it.
8. Protect the extension cords from sharp objects,
excessive heat, and damp
or wet areas.
