IMPORTANT SAFETY INFORMATION

GENERAL POWER TOOL SAFETY WARNINGS

Read all safety warnings and all instructions.

Failure to follow the warnings and instructions may
result in electric shock, fire and/or serious injury. Save

all warnings and instructions for future reference.

The term ″power tool″ in the warnings refers to your
battery-operated (cordless) power tool.

Work Area Safety

1. Keep work area clean and well lit.

Cluttered or dark areas invite accidents.

2. Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools

create sparks which may ignite the dust or fumes.

3. Keep children and bystanders
away while operating a power tool.

Distractions can cause you to lose control.

Electrical Safety

1. Power tool plugs must match the outlet.
Never modify the plug in any way.
Do not use any adapter plugs with grounded
power tools. Unmodified plugs and matching

outlets will reduce risk of electric shock.

2. 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.

3. Do not expose power tools to rain or wet
conditions. Water entering a power tool

will increase the risk of electric shock.

4. Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled

cords increase the risk of electric shock.

5. When operating a power tool outdoors,
use an extension cord suitable for
outdoor use. Use of a cord suitable for outdoor

use reduces the risk of electric shock.

6. If operating a power tool in a damp location
is unavoidable, use a Ground Fault Circuit
Interrupter (GFCI) protected supply.

Use of a GFCI reduces 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 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. Protective 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 Trigger
is in the off-position before connecting to
power source, picking up or carrying the tool.

Carrying power tools with your finger on

the Trigger or energizing power tools that
have the Trigger 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

dust collection 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 Trigger
does not turn it on and off. Any power tool

that cannot be controlled with the 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.

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. Keep cutting tools sharp and clean. Properly

maintained cutting tools with sharp cutting edges

are less likely to bind and are easier to control.

7. 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.

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.

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

battery may cause irritation or burns.

Service

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.

Drill Safety Warnings

1. Use auxiliary handle(s), if supplied with the tool.

Loss of control can cause personal injury.

2. Hold power tool by insulated gripping surfaces,
when performing an operation where the
cutting accessory may contact hidden wiring.

Cutting accessory contacting a ″live″ wire may
make exposed metal parts of the power tool ″live″
and could give the operator an electric shock.

3. Let bit cool before touching, changing
or adjusting it. Bits heat up dramatically
while in use, and can burn you.

4. If the drill bit jams, release the Trigger immediately;
drill torque can cause injury or break bit.

5. Maintain labels and nameplates on the tool.
These carry important safety information.
If unreadable or missing, contact
Harbor Freight Tools for a replacement.

6. Avoid unintentional starting. Prepare to
begin work before turning on the tool.

7. 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.

8. When using a handheld power tool,
maintain a firm grip on the tool with both
hands to resist starting torque.

9. Do not leave the tool unattended when the
Battery Pack is connected. Turn off the tool,
and remove the Battery Pack before leaving.

10. 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.

11. This product is not a toy.
Keep it out of reach of children.

12. 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.

13. 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.
