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.

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/trigger
does not turn it on and off.
Any power tool that cannot be controlled with the
switch/trigger is dangerous and must be repaired.
3. Disconnect 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.
Battery tool use and care
1. 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.
2. Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
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. 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.
3. 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.
4. 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
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.
Impact Wrench Safety Warnings
SAFETYOPERATIONMAINTENANCESETUP
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. The amount of actual torque may vary depending
on the cleanness and condition of the threads and
other factors. If tightening critical components,
check the actual torque applied to the fastener
with a mechanical torque wrench (not supplied).
3. Maintain labels and nameplates on the tool.
These carry important safety information.
If unreadable or missing, contact
Harbor Freight Tools for a replacement.
4. Avoid unintentional starting.
Prepare to begin work before turning on the tool.
5. 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.
6. When using a handheld power tool,
maintain a firm grip on the tool with both
hands to resist starting torque.
7. Do not leave the tool unattended when the
Battery Pack is connected. Turn off the tool,
and remove the Battery Pack before leaving.
8. The battery Charger gets hot during use.
The Charger’s heat can build up to unsafe
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 Pack while charging.
9. This product is not a toy.
Keep it out of reach of children.
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. WARNING: The cord of this product contains
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.)
12. 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.
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.
