3. Personal safety
to operate the power tool. Power tools are
dangerous in the hands of untrained users.
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 influence of drugs, alcohol or medication.
A moment of inattention while operating power
tools may result in serious personal injury.
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.
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.
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.
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.
5. Charger use and care
a. Recharge only with the charger specified by
the manufacturer. A charger that is suitable
for one type of battery pack may create a risk
of fire when used with another battery pack.
d. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
b. Under abusive conditions, liquid may be
ejected from the battery; avoid contact.
If contact accidentally occurs, flush with
water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the
battery may cause irritation or burns.
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.
6. 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.
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 ANSI-
approved and breathing protection must be NIOSH-
approved for the specific hazards in the work area.
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.
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.
2. Maintain labels and nameplates on the tool.
These carry important safety information. If
unreadable or missing, contact Harbor
Freight Tools for a replacement.
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.
3. Avoid unintentional starting. Prepare to
begin work before turning on the tool.
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.
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 firm grip
on the tool with both hands to resist starting torque.
d. Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions

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.
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:
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 fields in close
proximity to heart pacemaker could cause pacemaker
interference or pacemaker failure. In addition, people
with pacemakers should:
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.
• 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:
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
• Lead from lead-based paints
• Crystalline silica from bricks and cement or other
masonry products
3. Wear suitable gloves to reduce the
vibration effects on the user.
• 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.
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.
(California Health & Safety Code § 25249.5, et seq.)
7. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.
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.)
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.
