2.  
3.  
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 flammables.  
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  
4.  
Grounded tools must be plugged into an outlet properly installed and  
grounded in accordance with all codes and ordinances. Never remove the  
grounding prong or modify the plug in any way. Do not use any adapter  
plugs. Check with a qualified electrician if you are in doubt as to whether  
the outlet is properly grounded. If the tools should electrically malfunction or  
break down, grounding provides a low resistance path to carry electricity away  
from the user.  
5.  
6.  
Double insulated tools are equipped with a polarized plug (one blade is  
wider than the other). This plug will fit in a polarized outlet only one way. If  
the plug does not fit fully in the outlet, reverse the plug. If it still does not  
fit, contact a qualified electrician to install a polarized outlet. Do not  
change the plug in any way. Double insulation  
eliminates the need for the  
three wire grounded power cord and grounded power supply system.  
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.  
7.  
8.  
Do not expose power tools to rain or wet conditions. Water entering a power  
tool will increase the risk of electric shock.  
Do not abuse the Power Cord. Never use the Power Cord to carry the tools  
or pull the Plug from an outlet. Keep the Power Cord away from heat, oil,  
sharp edges, or moving parts. Replace damaged Power Cords immediately.  
Damaged Power Cords increase the risk of electric shock.  
9.  
When operating a power tool outside, use an outdoor extension cord  
marked “W-A” or “W”. These extension cords are rated for outdoor use, and  
reduce the risk of electric shock.

PERSONAL SAFETY  
10.  
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.  
11.  
12.  
13.  
14.  
15.  
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.  
Avoid accidental starting. Be sure the Power Switch is off before plugging  
in. Carrying power tools with your finger on the Power Switch, or plugging in  
power tools with the Power Switch on, invites accidents.  
Remove adjusting keys or wrenches before turning the power tool on. A  
wrench or a key that is left attached to a rotating part of the power tool may result  
in personal injury.  
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.  
Use safety equipment. Always wear eye protection. Dust mask, non-skid  
safety shoes, hard hat, or hearing protection must be used for appropriate  
conditions.  
TOOL USE AND CARE  
16.  
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.  
17.  
18.  
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.  
Do not use the power tool if the Power Switch does not turn it on or off.  
Any tool that cannot be controlled with the Power Switch is dangerous and must  
be replaced.  
19.  
20.  
Disconnect the Power Cord Plug from the power source before making any  
adjustments, changing accessories, or storing the tool. Such preventive  
safety measures reduce the risk of starting the tool accidentally.  
Store idle tools out of reach of children and other untrained persons. Tools  
are dangerous in the hands of untrained users.

21.  
22.  
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.  
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.  
23.  
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.  
SERVICE  
24.  
25.  
Tool service must be performed only by qualified repair personnel. Service  
or maintenance performed by unqualified personnel could result in a risk of injury.  
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.  
SPECIFIC SAFETY RULES  
1.  
Hold tool by insulated gripping surfaces when performing an operation  
where the cutting tools 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.  
3.  
Always wear ANSI approved safety impact eye goggles and full face shield  
when operating this product.  
Maintain labels and nameplates on the Drill. These carry important  
information. If unreadable or missing, contact Harbor Freight Tools for a  
replacement.  
4.  
5.  
Do not reach under or behind the material being drilled.  
Make sure the workpiece is free from nails and any other foreign objects  
which can damage a drill bit.  
6.  
7.  
Maintain a firm grip with both hands on the Drill, and position your body  
and arm to allow you to resist torque forces.  
Do not use a dull or damaged drill bits. Unsharpened or damaged drill bits  
cause excessive friction and binding.

GROUNDING  
WARNING!  
Improperly connecting the grounding wire can result in the risk of electric shock.  
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

GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS  
1.  
Tools and equipment 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 or equipment 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 Figure A.)  
2.  
3.  
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 Figure A.)  
Your tool must be plugged into an appropriate outlet, properly installed and  
grounded in accordance with all codes and ordinances. The plug and outlet  
should look like that in the following illustration. (See Figure A.)  
FIGURE A  
DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS  
1.  
2.  
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 Figure B.)  
Double insulated tools may be used in either of the 120 volt outlets shown in the  
following illustration. (See Figure B.)  
SKU 92956  
For technical questions please call 1-800-444-3353  
PAGE 7  
 
FIGURE B  
EXTENSION CORDS  
1.  
2.  
Grounded tools require a three wire extension cord. Double Insulated tools  
can use either a two or three wire extension cord.  
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  
serious drop in voltage, resulting in loss of power and possible tool damage.  
(See Figure C, next page.)  
3.  
The smaller the gauge number of the wire, the greater the capacity of the cord.  
For example, a 14 gauge cord can carry a higher current than a 16 gauge cord.  
(See Figure C.)  
4.  
5.  
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 Figure C.)  
If you are using one extension cord for more than one tool, add the nameplate  
amperes and use the sum to determine the required minimum cord size.  
(See Figure C.)  
6.  
7.  
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.  
Make sure your extension cord is properly wired and in good electrical condition.  
Always replace a damaged extension cord or have it repaired by a qualified  
electrician before using it.  
8.  
Protect your extension cords from sharp objects, excessive heat, and damp or  
wet areas.

2.  
Drill Chuck (3) and Chuck Key (33): The Close Quarter Drill is equipped with a  
3/8” keyed Drill Chuck (3) that will accept drill bits (not included) with a 1/16” to  
3/8” shank. Installing a drill bit into the Drill Chuck requires the use of the  
accessory Chuck Key (33). Always make sure the drill bits are firmly secured in  
the Drill Chuck prior to using the Drill. (See Figure D.)  
Trigger (30) and Trigger Lock (34): The Trigger (30) is operated manually  
simply by squeezing the Trigger to turn on the Drill and releasing pressure on the  
Trigger to turn off the Drill. The Trigger features a Trigger Lock (34) for continuous  
running of the Drill. To set the Drill in a continuous run mode, squeeze the  
Trigger and depress the Trigger Lock. Then, release pressure on the Trigger.  
The Drill will continue to run. To turn off the Drill, squeeze and let up on the  
Trigger. (See Figure D.)

OPERATING INSTRUCTIONS  
1.  
Use caution when drilling into existing walls or other blind areas. Check for  
unexposed electrical wires and cables in the drilling path before drilling.  
2.  
3.  
4.  
Use the Forward/Reverse Switch (35) to select the desired rotation of the tool.  
(See Figure D.)  
Insert a drill bit (not included) into the Drill Chuck (3), and secure the drill bit in  
the Drill Chuck with the Chuck Key (33). (See Figure D.)  
Make sure the Trigger (30) is in its “OFF” position. Then, plug the Power Cord/  
Plug (31) into the nearest 120 volt, grounded, electrical outlet. (See Figure D.)  
5.  
6.  
Before drilling, clamp the object down securely. A poorly secured piece of  
material may result in personal injury and/or innacurate drilling.  
Mark the center of the hole to be drilled with a center punch to prevent the drill bit  
from “walking” when first beginning to drill.  
7.  
8.  
9.  
Hold the Drill firmly with both hands.  
Position the drill bit on the material that is to be drilled.  
To begin drilling, squeeze the Trigger (30). The speed at which the Drill Chuck  
(3) rotates varies depending on how far in the Trigger is squeezed.  
(See Figure D.)  
10.  
11.  
If desired, activate the Trigger Lock (34) to set the Drill in a continuous run mode.  
(See Figure D.)  
Avoid overloading the Drill. Do not apply excessive pressure to the Drill while  
drilling. If the speed of the tool drops abnormally, decrease the pressure  
immediately. If the drill bit stops abruptly, or the drill bit becomes blocked, release  
the Trigger (30) at once. (See Figure D.)  
12.  
13.  
Drill only as deep as is necessary. Do not drill deeper than necessary into walls  
or other areas where you cannot identify any possible hazards behind the drilling  
surface.  
To reduce jamming as the drill bit breaks through the workpiece, decrease the  
drilling pressure when the point of the drill bit breaks through the workpiece.

PAGE 11  
 
14.  
When you have drilled the hole, remove the drill bit from the hole while the Drill  
Chuck (3) is still rotating. This prevents the drill bit from getting caught in the  
hole and causing damage.  
15.  
16.  
17.  
Release pressure on the Trigger (30) to stop the Drill. (See Figure D.)  
Unplug the Drill from its electrical outlet.  
Remove the drill bit from the Drill Chuck (3). Then, store the Drill and its Chuck  
Key (33) in a dry, safe, location out of reach of children and other unauthorized  
users.  
INSPECTION, MAINTENANCE, AND CLEANING  
1.  
2.  
WARNING! Always make sure the Trigger (30) is in its “OFF” position, and  
unplug the Power Cord/Plug (31) from its 120 volt electrical outlet before  
performing any inspection, adjustments, maintenance, or cleaning.  
Before each use, inspect the general condition of the Drill. Check for loose  
screws, misalignment or binding of moving parts, cracked or broken parts,  
damaged electrical wiring, loose, cracked, or bent drill bits, and any other  
condition that may affect its safe operation. If abnormal noise or vibration occurs,  
have the problem corrected before further use.  
Do not use damaged equipment.  
3.  
4.  
Daily: With a soft brush, cloth, or vacuum, remove all dust and debris from the  
Drill. Then, use a premium quality, lightweight machine oil to lubricate  
all external moving parts.  
To replace the Carbon Brushes: It may become necessary at sometime to  
replace the two Carbon Brushes (19) when the Motor performance decreases, or  
stops working completely. The Carbon Brushes are located on each side of  
the Motor Housing (4) and Motor Housing Cover (17). To do so, remove the  
two Brush Holder Covers (18). Then, remove the two Carbon Brushes from the  
Brush Holders (20). If the Carbon Brushes are worn down more than 1/2,  
replace both Carbon Brushes. If, however, the Carbon Brushes are just dirty they  
may be cleaned by rubbing them with a pencil eraser. When installing the  
Carbon Brushes, make sure the carbon portion of the Carbon Brushes contact  
the Motor Armature, and that the springs face away from the Motor. Also, make  
sure the springs operate freely. After cleaning or replacement, replace the Brush  
Holders. NOTE: New Carbon Brushes tend to arc or spark when first used  
until they wear and conform to the Motor’s Armature. (See Figure E, next page.)
