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.

Page 2 For technical questions, please call 1-800-444-3353. SKU 69451

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.

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.

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.

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.

Power tool use and care

1. Do not force the power tool.

SAFETY OPERATION MAINTENANCESETUP

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.

Page 4 For technical questions, please call 1-800-444-3353. SKU 69451

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,
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 filter out
microscopic particles.
(California Health & Safety Code

§ 25249.5, et seq.)

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.

9. WARNING: Handling the cord on this
product will expose you to 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.)

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.

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.
