GENERAL SAFETY RULES
WARNING! Read all
instructions
Failure to follow all instructions
listed below may result in
electric shock, re, and/or
serious injury. The term “power
tool” in all of the warnings listed
below refers to your line-operated
(corded) power tool or batteryoperated (cordless) power tool.
SAVE THESE INSTRUCTIONS
Work area safety1.
Keep work area clean and well a.
lit. Cluttered or dark areas invite
accidents.
Do not operate power tools in b.
explosive atmospheres, such as in
the presence of ammable liquids,
gases or dust. Power tools create
sparks which may ignite the dust or
fumes.
Keep children and bystanders c.
away while operating a power
tool. Distractions can cause you
to lose control.
Electrical safety2.
Power tool plugs must match the a.
outlet. Never modify the plug in
any way. Do not use any adapter
plugs with grounded power tools.
Unmodied plugs and matching
outlets will reduce risk of electric
shock.
Do not expose power tools to b.
rain or wet conditions. Water en-
tering a power tool will increase
the risk of electric shock.
Do not abuse the cord. Never c.
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.
Personal safety3.
Stay alert, watch what you are do-a.
ing and use common sense when
operating a power tool. Do not use
a power tool while you are tired
or under the inuence of drugs,
alcohol or medication. A moment
of inattention while operating power
tools may result in serious personal
injury.
Use safety equipment. Always b.
ANSI-approved 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.
Avoid accidental starting. Ensure c.
the switch is in the off-position
before plugging in. Carrying power
tools with your nger on the switch
or plugging in power tools that have
the switch on invites accidents.
Dress properly. Do not wear loose d.
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.
Page 2SKU 97626 For technical questions, please call 1-800-444-3353.
Power tool use and care4.
Do not force the power tool. Use a.
the correct power tool for your ap-
plication. The correct power tool
will do the job better and safer at
the rate for which it was designed.
Do not use the power tool if the b.
switch does not turn it on and off.
Any power tool that cannot be con-
trolled with the switch is dangerous
and must be repaired.
Disconnect the plug from the c.
power source from the power
tool before making any adjust-
ments, changing accessories, or
storing power tools. Such pre-
ventive safety measures reduce
the risk of starting the power tool
accidentally.
Store idle power tools out of the d.
reach of children and do not al-
low persons unfamiliar with the
power tool or these instructions
to operate the power tool. Power
tools are dangerous in the hands
of untrained users.
Maintain power tools. Check for e.
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.
Keep cutting tools sharp and clean. f.
Properly maintained cutting tools
with sharp cutting edges are less
likely to bind and are easier to
control.
Use the power tool, accessories g.
and tool bits etc., in accordance
with these instructions and in the
manner intended for the particular
type of power tool, taking into ac-
count 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.
VIBRATION HAZARD
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:
Anyone using vibrating tools regularly 1.
or for an extended period should rst
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
ngers), seek medical advice as soon
as possible.
Do not smoke during use. Nicotine 2.
reduces the blood supply to the hands
and ngers, increasing the risk of
vibration-related injury.
Wear suitable gloves to reduce the 3.
vibration effects on the user.
Use tools with the lowest vibration 4.
when there is a choice between different processes.
Include vibration-free periods each 5.
day of work.
Grip tool as lightly as possible (while 6.
still keeping safe control of it). Let the
tool do the work.
Page 3SKU 97626 For technical questions, please call 1-800-444-3353.
To reduce vibration, maintain the tool 7.
as explained in this manual. If any
abnormal vibration occurs, stop use
immediately.
SPECIFIC SAFETY RULES
Maintain labels and nameplates on 1.
the tool. These carry important safety
information. If unreadable or missing, contact Harbor Freight Tools for a
replacement.
Avoid unintentional starting. Prepare 2.
to begin work before turning on the
tool.
Do not lay the tool down until it has 3.
come to a complete stop. Moving
parts can grab the surface and pull
the tool out of your control.
When using a handheld power tool, 4.
maintain a rm grip on the tool with
both hands to resist starting torque.
Do not leave the tool unattended 5.
when it is plugged into an electrical
outlet. Turn off the tool, and unplug it
from its electrical outlet before leaving.
Use clamps (not included) or other 6.
practical ways to secure and support
the workpiece to a stable platform.
Holding the work by hand or against
your body is unstable and may lead to
loss of control.
This product is not a toy. Keep it out 7.
of reach of children.
People with pacemakers should 8.
consult their physician(s) before use.
Electromagnetic elds 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.
Some dust created by power sanding, 9.
sawing, grinding, drilling, and other
construction activities, contains chemicals known [to the State of California]
to cause cancer, birth defects or other
reproductive harm. Some examples
of these chemicals are:
Lead from lead-based paints
Crystalline silica from bricks and cement or other masonry products
Arsenic and chromium from chemically treated lumber
Your risk from these exposures varies, depending on how often you do
this type of work. To reduce your
exposure to these chemicals: work in
a well ventilated area, and work with
approved safety equipment, such as
those dust masks that are specially
designed to lter out microscopic
particles. (California Health & Safety
Code § 25249.5, et seq.)
WARNING: The brass components of 10.
this product contain lead, a chemical
known to the State of California to
cause birth defects (or other reproductive harm). (California Health &
Safety code § 25249.5, et seq.)
The warnings, precautions, and 11.
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.

SAVE THESE
INSTRUCTIONS.
make sure each cord contains at least
the minimum wire size required. (See
Table A.)
GROUNDING
Improperly
WARNING
grounding wire can result in
electric shock.
Check with a qualied
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
t the outlet, have a proper
outlet installed by a qualied
electrician.
Extension Cords
Grounded1. tools require a three wire
extension cord. Double Insulated
tools can use either a two or three
wire extension cord.
As the distance from the supply outlet 2.
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.)
The smaller the gauge number of the 3.
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.)
When using more than one exten-4.
sion cord to make up the total length,
connecting the
If you are using one extension cord 5.
for more than one tool, add the nameplate amperes and use the sum to
determine the required minimum cord
size. (See Table A.)
Make sure the extension cord is 6.
properly wired and in good electrical
condition. Always replace a damaged
extension cord or have it repaired by
a qualied electrician before using it.
