3. Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control. Protect others in the work area from
debris such as chips and sparks. Provide barriers or shields as needed.
ELECTRICAL SAFETY
1. Avoid body contact with grounded surfaces such as pipes, radiators, ranges,
and refrigerators. There is an increased risk of electric shock if your body is
grounded.
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 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. Dress properly. Do not wear loose clothing or jewelry. Contain long hair.
Keep your hair, clothing, and gloves away from moving parts. Loose clothes,
jewelry, or long hair can be caught in moving parts.
3. Avoid accidental starting. Be sure the Trigger is released before plugging
in. Carrying power tools with your finger on the Trigger, or plugging in power tools
with the Trigger depressed, invites accidents.
4. Remove adjusting keys or wrenches before using the power tool. A wrench or
a key that is 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. Proper footing
and balance enables better control of the power tool in unexpected situations.
6. Use safety equipment. Always wear ANSI approved safety glasses underneath
a full face safety shield. Dust mask, nonskid safety shoes, hard hat, or hearing
protection must be used for appropriate conditions.
7. Use clamps (not included) or other practical ways to secure and support
the workpiece to a stable platform. Holding the work by hand or against your
body is unstable and may lead to loss of control.

TOOL USE AND CARE
1. Do not force the tool. Use the correct tool for your application. The correct
tool will do the job better and safer at the rate for which it is designed.
2. Do not use the power tool if the Trigger does not turn it on or off. Any tool
that cannot be controlled with the Trigger is dangerous and must be replaced.
3. Disconnect the power tool from its Battery Pack (15) before making any
adjustments, changing accessories, or storing the tool. Such preventive
safety measures reduce the risk of starting the tool accidentally.
4. Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.
5. Maintain tools with care. Keep cutting tools sharp and clean. Properly
maintained tools with a sharp cutting edge are less likely to bind and are easier
to control. Do not use a damaged tool. Tag damaged tools “Do not use” until
repaired.
6. Check for misalignment or binding of moving parts, breakage of parts, and
any other condition that may affect the tool’s operation. If damaged, have
the tool serviced before using. Many accidents are caused by poorly
maintained tools.
7. Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitable for one tool may become hazardous
when used on another tool.
SPECIFIC SAFETY RULES
1. Maintain a safe working environment. Keep the work area well lit. Make sure
there is adequate surrounding workspace. Always keep the work area free of
obstructions, grease, oil, trash, and other debris. Do not use the Cordless Drill in
areas near flammable chemicals, dusts, and vapors. Do not use this product in a
damp or wet location.
SERVICE
1. Tool service must be performed only by qualified repair personnel. Service
or maintenance performed by unqualified personnel could result in injury.
2. When servicing a tool, use only identical replacement parts. Follow
instructions in the “Inspection, Maintenance, And Cleaning” section of this
manual. Use of unauthorized parts or failure to follow maintenance instructions
may create a risk of electric shock or injury.

SKU 93142 For technical questions, please call 1-800-444-3353 PAGE 5
2. Maintain labels and nameplates on this product. These carry important
information. If unreadable or missing, contact Harbor Freight Tools for a replacement.
3. When using the Cordless Drill, always maintain a firm grip on the tool with
both hands.
4. Hold the tool by its insulated gripping surfaces when performing an operation
where the Cordless Drill may contact hidden wiring. Contact with a “live” wire
will make exposed metal parts of the Cordless Drill “live” and shock the operator.
This is just an additional precaution; always check for hidden wiring before
drilling.
5. Do not use the Cordless Drill or Charger (21) if it has been dropped, damaged,
left outdoors, or immersed in liquid.
6. To avoid electrical shock, do not handle the Charger (21), its Power Cord Plug,
or the Cordless Drill with wet hands.
7. Keep the Handle of the Cordless Drill dry, clean, and free from oil and grease.
8. Always turn off the Cordless Drill and unplug the Charger (21) from its electrical
outlet before changing accessories or performing any inspection,
maintenance, or cleaning procedures.
9. Avoid unintentional starting. Make sure you are prepared to begin work before
turning on the Cordless Drill.
10. To avoid electrical shock, do not pull or carry the Charger (21) by its Power
Cord.
11. Never leave the Charger (21) unattended when it is plugged into an electrical
outlet. Make sure to unplug it from its electrical outlet before leaving.
12. Proper Battery Pack Care: Battery Pack (15) leakage may occur under extreme
usage or temperature conditions. If Battery Pack fluid comes in contact with skin,
wash with soap and water and rinse with lemon juice and vinegar. If the fluid comes
into contact with the eyes, flush with water for several minutes and contact a doctor
immediately. Never burn the Battery Pack, as it can explode in a fire. Do not charge
the Cordless Drill with a leaking Battery Pack. Contact local solid waste authorities
for instructions on correct disposal or recycling of the Battery Pack.
13. Use clamps (not included) or other practical ways to secure and support the
workpiece to a stable platform. Holding the work by hand or against your body is
unstable and may lead to loss of control.

SKU 93142 For technical questions, please call 1-800-444-3353 PAGE 6
14. Always switch to a fresh Battery Pack (15) when tool performance begins to
diminish. Severe heat is most destructive to a Battery Pack. The more heat
generated, the faster the Battery Pack loses power. A Battery Pack that gets too hot
can be permanently damaged. Never over-discharge a Battery Pack by using the
tool while tool performance is decreasing. Never attempt to discharge a tool’s Battery
Pack by continuing to pull the tool Trigger. When tool performance begins to diminish,
stop the tool, recharge the Battery Pack, and use the fresh Battery Pack for optimal
performance.
15. WARNING! Some dust created by power sanding, sawing, grinding, drilling,
and other construction activities, contain 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.)
16. WARNING! People with pacemakers should consult their physician(s) before
using this product. Electromagnetic fields in close proximity to a heart pacemaker
could cause interference or failure of the pacemaker. In addition, people with
pacemakers should adhere to the following: Avoid operating power tools alone.
Don’t use a power tool with the power switch (Trigger) locked on. If powered via a
power cord be certain that the tool is properly grounded. A ground fault interrupt
(GFCI) system is also a good precaution. This inexpensive device is a good safety
measure because it prevents a sustained electrical shock. Properly maintain and
inspect all tools before use to avoid electrical shock.
17. WARNING! The warnings, precautions, and instructions discussed in this
manual cannot cover all possible conditions and situations that may occur. The
operator must understand that common sense and caution are factors which cannot
be built into this product, but must be supplied by the operator.
