general saFetY rules  
warning read all safety warnings and 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.  
saVe these instruCtions  
1. work area safety  
a. Keep work area clean and well lit. Cluttered or dark areas invite accidents.  
b. 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.  
c. Keep children and bystanders away while operating a power tool. Distractions  
can cause you to lose control.  
2. electrical safety  
a. 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.  
b. 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.  
c. Do not expose power tools to rain or wet conditions. Water entering a power tool  
will increase the risk of electric shock.  
d. 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. Dam-  
aged or entangled cords increase the risk of electric shock.  
e. 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.  
f. 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.  
3. personal safety  
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.

b. use safety equipment. always wear ansi-approved eye protection. Safety  
equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protec-  
tion used for appropriate conditions will reduce personal injuries.  
c. Prevent unintentional starting. Ensure the switch is in the off-position before con-  
necting to power source and/or battery pack, picking up or carrying the tool. Car-  
rying power tools with your finger on the switch or energizing power tools that  
have the switch on invites accidents.  
d. 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.  
e. Do not overreach. Keep proper footing and balance at all times. This enables  
better control of the power tool in unexpected situations.  
f. 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.  
g. If devices are provided for the connection of dust extraction and collection facili-  
ties, ensure these are connected and properly used. Use of these devices can  
reduce dust-related hazards.  
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 de-  
signed.  
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 pow-  
er tool before making any adjustments, changing accessories, or storing power  
tools. Such preventive safety measures reduce the risk of starting the power tool  
accidentally.  
d. Store idle power tools out of the reach of children and do not allow persons unfa-  
miliar with the power tool or these instructions to operate the power tool. Power  
tools are dangerous in the hands of untrained users.  
e. Maintain power tools. Check for misalignment or binding of moving parts, break-  
age 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.  
f. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp  
cutting edges are less likely to bind and are easier to control.  
g. 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.

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 an-  
other battery pack.  
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 con-  
nection from one terminal to another. Shorting the battery terminals together may  
cause burns or a fire.  
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.  
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.  
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 sys-  
tem disorders, diabetes, or Raynaud’s Disease should not use this tool. If you feel  
any medical or physical 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 between different pro-  
cesses.  
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.  
SKU 97925, 99676  
For technical questions, please call 1-800-444-3353.

7. To reduce vibration, maintain the tool as explained in this manual. If any abnormal  
vibration occurs, stop use immediately.  
drill and impact drill safety warnings  
1. wear ear protectors with impact drills. Exposure to noise can cause hearing  
loss.  
2. use auxiliary handles supplied with the tool. Loss of control can cause person-  
al injury.  
3. hold power tools by insulated gripping surfaces when performing an opera-  
tion where the cutting tool may contact hidden wiring or its own cord. con-  
tact with a ″ live″ wire will make exposed metal parts of the tool ″ live″ and shock  
the operator.  
4. Maintain labels and nameplates on the tool. These carry important safety informa-  
tion. If unreadable or missing, contact Harbor Freight Tools for a replacement.  
5. Avoid unintentional starting. Prepare to begin work before turning on the tool.  
6. 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.  
7. When using a handheld power tool, maintain a firm grip on the tool with both hands  
to resist starting torque.  
8. 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.  
9.  
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 ad-  
equate 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 during use.  
10. This product is not a toy. Keep it out of reach of children.  
11. People with pacemakers should consult their physician(s) before use. Electromag-  
netic fields in close proximity to heart pacemaker could cause pacemaker interfer-  
ence or pacemaker failure. In addition, people with pacemakers should:  
• Avoid operating alone.  
• Do not use with power switch locked on.

• Properly maintain and inspect to avoid electrical shock.  
• Any power cord must be properly grounded. Ground Fault Circuit Interrupter  
(gFCI) should also be implemented – it prevents sustained electrical shock.  
12. Some dust created by power sanding, sawing, grinding, drilling, and other con-  
struction activities, contains chemicals known [to the State of California] to cause  
cancer, birth defects or other reproductive harm. Some examples of these chemi-  
cals 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 spe-  
cially designed to filter out microscopic particles. (California Health & Safety Code  
§ 25249.5, et seq.)  
13. WARNINg: Handling the cord on this product will expose you to lead, a chemical  
known to the State of California to cause cancer, and birth defects or other re-  
productive harm. Wash hands after handling. (California Health & Safety Code §  
25249.5, et seq.)  
14. The warnings, precautions, and instructions discussed in this instruction manual  
cannot cover all possible conditions and situations that may occur. It must be un-  
derstood by the operator that common sense and caution are factors which cannot  
be built into this product, but must be supplied by the operator.

grounding  
improperly connecting the grounding wire can result in  
electric shock.  
WARNINg  
to preVent eleCtriC shoCk and death From inCorreCt  
grounding wire ConneCtion:  
Check with a qualified electrician if you are in doubt as to whether  
the outlet is properly grounded. do not modify the power cord plug  
provided with the tool. never remove the grounding prong from the  
plug. do not use the tool if the power cord or plug is damaged. if  
damaged, have it repaired by a service facility before use. if the plug  
will not fit the outlet, have a proper outlet installed by a qualified  
electrician.

grounded tools: tools with three prong plugs  
1. Tools marked with “Grounding Required” have a three wire cord and three prong  
grounding plug. The plug must be connected to a properly grounded outlet. If  
the tool should electrically malfunction or break down, grounding provides a low  
resistance path to carry electricity away from the user, reducing the risk of electric  
shock. (see 3-prong plug and outlet.)  
2. The grounding prong in the plug is connected through the green wire inside the  
cord to the grounding system in the tool. The green wire in the cord must be the  
only wire connected to the tool’s grounding system and must never be attached to  
an electrically “live” terminal. (see 3-prong plug and outlet.)  
3. The tool must be plugged into an appropriate outlet, properly installed and ground-  
ed in accordance with all codes and ordinances. The plug and outlet should look  
like those in the preceding illustration. (see 3-prong plug and outlet.)  
outlets for 2-prong plug  
3-prong plug and outlet  
double insulated tools: tools with two prong plugs  
1. Tools marked “Double Insulated” do not require grounding. They have a special  
double insulation system which satisfies OSHA requirements and complies with the  
applicable standards of Underwriters Laboratories, Inc., the Canadian Standard  
Association, and the National Electrical Code. (see outlets for 2-prong plug.)  
2. Double insulated tools may be used in either of the 120 volt outlets shown in the  
preceding illustration. (see outlets for 2-prong plug.)  
extension Cords  
1. Grounded tools require a three wire extension cord. Double Insulated tools can  
use either a two or three wire extension cord.  
2. As the distance from the supply outlet increases, you must use a heavier gauge  
extension cord. Using extension cords with inadequately sized wire causes a seri-  
ous drop in voltage, resulting in loss of power and possible tool damage.  
(see table a.) The smaller the gauge number of the wire, the greater the capac-

ity of the cord. For example, a 14 gauge cord can carry a higher current than a 16  
gauge cord. (see table a.)  
3. When using more than one extension cord to make up the total length, make sure  
each cord contains at least the minimum wire size required. (see table a.)  
4. If you are using one extension cord for more than one tool, add the nameplate am-  
peres and use the sum to determine the required minimum cord size. (see table  
a.)  
5. If you are using an extension cord outdoors, make sure it is marked with the suffix  
“W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.  
6. Make sure the extension cord is properly wired and in good electrical condition.  
Always replace a damaged extension cord or have it repaired by a qualified electri-  
cian before using it.  
7. Protect the extension cords from sharp objects, excessive heat, and damp or wet  
areas.

Harbor Freight Tools Co. makes every effort to assure that its products meet high quality  
and durability standards, and warrants to the original purchaser that this product is free  
from defects in materials and workmanship for the period of 90 days from the date of  
purchase. This warranty does not apply to damage due directly or indirectly, to misuse,  
abuse, negligence or accidents, repairs or alterations outside our facilities, criminal  
activity, improper installation, normal wear and tear, or to lack of maintenance. We shall  
in no event be liable for death, injuries to persons or property, or for incidental, contingent,  
special or consequential damages arising from the use of our product. Some states do  
not allow the exclusion or limitation of incidental or consequential damages, so the above  
limitation of exclusion may not apply to you. This warranty is expressly in lieu of all other  
warranties, express or implied, including the warranties of merchantability and fitness.  
To take advantage of this warranty, the product or part must be returned to us with  
transportation charges prepaid. Proof of purchase date and an explanation of the complaint  
must accompany the merchandise. If our inspection verifies the defect, we will either  
repair or replace the product at our election or we may elect to refund the purchase price  
if we cannot readily and quickly provide you with a replacement. We will return repaired  
products at our expense, but if we determine there is no defect, or that the defect resulted  
from causes not within the scope of our warranty, then you must bear the cost of returning  
the product.  
This warranty gives you specific legal rights and you may also have other rights which  
vary from state to state.
