3. Personal safety
power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
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.
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.
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.
5. Battery tool 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.
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.
b. Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
c. When battery pack is not in use, keep it away
from other metal objects, like paper clips,
coins, keys, nails, screws or other small metal
objects, that can make a connection from
one terminal to another. Shorting the battery
terminals together may cause burns or a fire.
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.
d. 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.
f. 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.
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.
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.
Impact Driver Safety Warnings
1. Let bit cool before touching, changing
or adjusting it. Bits heat up dramatically
while in use, and can burn you.
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.
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.
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.
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
e. Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
on the tool with both hands to resist starting torque.

6.
The battery charger gets hot during use.
The charger’s heat can build up to unsafe
Lithium Battery Safety Warnings
levels and create a fire hazard if it does not
receive adequate ventilation, due to an
electrical fault, or if it is used in a hot environment.
Do not place the charger on a flammable surface. Do
not obstruct any vents on the charger. Especially
avoid placing the charger on carpets and rugs; they
are not only flammable, but they also obstruct
vents under the charger.
Place the charger on a stable, solid, nonflammable
surface (such as a stable metal workbench or concrete
floor) at least 1 foot away from all flammable objects,
such as drapes or walls. Keep a fire extinguisher and a
smoke detector in the area. Frequently monitor the
charger and battery while charging.
LITHIUM BATTERIES STORE A LARGE
AMOUNT OF ENERGY AND WILL VENT
FIRE OR EXPLODE IF MISTREATED:
1. Keep Battery Pack dry.
2. DO NOT DO ANY OF THE FOLLOWING
7. This product is not a toy. Keep it
out of reach of children.
TO THE BATTERY PACK:
a. Open,
b. Drop,
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:
c. Short-circuit,
d. Incinerate, or
e. Expose to temperatures greater than 140°F.
3. Charge Battery Pack only according to
the instructions in this manual.
• Avoid operating alone.
• Do not use with power switch locked on.
• Properly maintain and inspect
4. Inspect Battery Pack before every use;
do not use or charge if damaged
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:
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:
• Lead from lead-based paints
• Crystalline silica from bricks and cement or other
masonry products
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.
• 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.)
10. WARNING: Handling the cord on this product’s charger
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.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
(California Health & Safety Code § 25249.5, et seq.)
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.
3. Wear suitable gloves to reduce the
vibration effects on the user.
4. Use tools with the lowest vibration
when there is a choice.

Extension Cords
6. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.
Note: Extension cords must not be used with this
item’s charger.
7. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.
