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 grounded
power tools. Unmodified plugs and matching
outlets will reduce risk of electric shock.
b. 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.
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.
CAUTION, without the safety alert symbol, is used
to address practices not related to personal injury.
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. Safety 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. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
e. 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.
f. 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 ANSIapproved and breathing protection must be NIOSHapproved for the specific hazards in the work area.
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 the battery pack 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. 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.
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.
Specific Safety Warnings
1. Maintain labels and nameplates on
the tool. These carry important safety
information. If unreadable or missing, contact
Harbor Freight Tools for a replacement.
2. Avoid unintentional starting. Prepare to
begin work before turning on the tool.
3. 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.
4. When using a handheld power tool, maintain a firm grip
on the tool with both hands to resist starting torque.
5. 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.
6. This product is not a toy. Keep it
out of reach of children.
7. 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 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.
8. WARNING: The cord of this product contains
lead, a chemical known to the State of California
to cause cancer, and birth defects or other
reproductive harm. Wash hands after handling.
(California Health & Safety Code § 25249.5, et seq.)
9. 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.
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.
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.
Double Insulated Tools:
Tools with Two Prong Plugs
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.
SAVE THESE
INSTRUCTIONS.
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 on page 5.)
3. The smaller the gauge number of the wire, the
greater the capacity of the cord. For example,
