IMPORTANT SAFETY INFORMATION
General Power Tool Safety Warnings
Read all safety warnings and 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. Do not expose power tools
to rain or wet conditions.
Water entering a power tool will
increase the risk of electric shock.
3. 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.
4. 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.

SAFETY OPERATION MAINTENANCESETUP
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. Safety 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, 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 these devices can
reduce dust-related hazards.
8. 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.

SAFETYOPERATIONMAINTENANCE SETUP
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
switch does not turn it on and off.
Any power tool that cannot be
controlled with the switch is
dangerous and must be repaired.
3. Disconnect the plug from
the power source 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.
Service
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.

Rotary Tool 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 depress the spindle lock
when starting or during operation.
6. 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.
7. This product is not a toy.
Keep it out of reach of children.
8. WARNING: Some dust created by
power sanding, sawing, grinding,

cancer and 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 filter out microscopic particles.
(California Health & Safety Code
§ 25249.5, et seq.)
9. WARNING: The cord of this

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.)
10.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.
11. 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.

SAFETYOPERATIONMAINTENANCE SETUP
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.
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.
