General Power Tool
Safety Warnings
WARNING Read all safety warnings and
instructions. Failure to follow the warnings and
instructions may result in electric shock, re 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
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
ammable 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. Do not expose power tools to rain or wet
conditions. Water entering a power tool
will increase the risk of electric shock.
Page 2 For technical questions, please call 1-800-444-3353. SKU 68394
3. Personal safety
a. 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 inuence 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 nger 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. 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.
g. 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 specic 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. 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. Charger use and care
a. Recharge only with the charger specied by
the manufacturer. A charger that is suitable
for one type of battery pack may create a risk
of re when used with another battery pack.
b. Under abusive conditions, liquid may be
ejected from the battery; avoid contact.
If contact accidentally occurs, ush with
water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the
battery may cause irritation or burns.
6. Service
a. Have your power tool serviced by a
qualied repair person using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.
Screwdriver Safety Warnings
1. 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″ and shock the operator.
2. Maintain labels and nameplates on the tool.
These carry important safety information. If
unreadable or missing, contact Harbor
Freight Tools for a replacement.
3. Avoid unintentional starting. Prepare to
begin work before turning on the tool.
4. 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.
5. When using a handheld power tool, maintain a rm grip
on the tool with both hands to resist starting torque.
Page 3For technical questions, please call 1-800-444-3353.SKU 68394
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. People with pacemakers should 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.
9. 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 lter
out microscopic particles.
(California Health & Safety Code § 25249.5, et seq.)
10. WARNING: Handling the cord on this product’s adapter
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.)
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 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 symptoms related to vibration (such
as tingling, numbness, and white or blue ngers),
seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and ngers,
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
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.
