6. Do not expose power tools to rain or wet  
conditions. Water entering a power tool will  
increase the risk of electric shock.  
against your body is unstable and may lead  
to loss of control.  
16. Do not force 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.  
7. Do not abuse the cord. Never use the cord  
to carry the tools or pull the plug from an  
outlet. Keep cord away from heat, oil,  
sharp edges or moving parts. Replace  
damaged cords immediately. Damaged  
cords increase the risk of electric shock.  
17. Do not use tool if switch does not turn it  
on or off. Any tool that cannot be controlled  
with the switch is dangerous and must be  
repaired.  
8. When operating a power tool outside, use  
an outdoor extension cord marked “W-A”  
or “W”. These cords are rated for outdoor  
use and reduce the risk of electric shock.  
18. Disconnect the 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.  
Personal Safety  
9. Stay alert, watch what you are doing and  
19. Store idle tools out of reach of children  
and other untrained persons. Tools are  
dangerous in the hands of untrained users.  
use common sense when operating  
a
power tool. Do not use 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.  
20. Maintain tools with care. Keep cutting  
tools sharp and clean. Properly maintained  
tools with sharp cutting edges are less likely  
to bind and are easier to control.  
10. Dress properly. Do not wear loose cloth-  
ing 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.  
21. Check for misalignment or binding of  
moving parts, breakage of parts, and any  
other condition that may affect the tools  
operation. If damaged, have the tool ser-  
viced before using. Many accidents are  
caused by poorly maintained tools.  
11. Avoid accidental starting. Be sure switch  
is off before plugging in. Carrying tools with  
your finger on the switch or plugging in tools  
that have the switch on invites accidents.  
22. Use only accessories that are recom-  
mended by the manufacturer for your  
model. Accessories that may be suitable for  
one tool, may become hazardous when used  
on another tool.  
12. Remove adjusting keys or wrenches  
before turning the tool on. A wrench or a  
key that is left attached to a rotating part of  
the tool may result in personal injury.  
SERVICE  
13. Do not overreach. Keep proper footing  
and balance at all times. Proper footing and  
balance enables better control of the tool in  
unexpected situations.  
23. Tool service must be performed only by  
qualified repair personnel. Service or main-  
tenance performed by unqualified personnel  
could result in a risk of injury.  
14. Use safety equipment. Always wear eye  
protection. Dust mask, non-skid safety  
shoes, hard hat, or hearing protection must  
be used for appropriate conditions. Ordinary  
eye or sun glasses are NOT eye protection.  
24. When servicing a tool, use only identical  
replacement parts. Follow instructions in  
the Maintenance section of this manual.  
Use of unauthorized parts or failure to follow  
Maintenance instructions may create a risk of  
electric shock or injury.  
Tool Use and Care  
15. Use clamps or other practical way to  
secure and support the workpiece to a  
stable platform. Holding the work by hand or

USE PROPER EXTENSION CORD: Make sure your extension cord is in good condition.  
When using an extension cord, be sure to use one heavy enough to carry the current your  
product will draw. An undersized cord will cause a drop in line voltage resulting in loss of  
power and overheating. Table 1 shows the correct size to use depending on cord length and  
nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage num-  
ber, the heavier the cord.

SPECIFIC SAFETY RULES  
USB001-2  
DO NOT let comfort or familiarity with product (gained from  
repeated use) replace strict adherence to drill safety rules. If  
you use this tool unsafely or incorrectly, you can suffer serious  
personal injury.  
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.  
4. Keep hands away from rotating parts.  
5. Do not leave the tool running. Operate the  
tool only when hand-held.  
6. Do not touch the drill bit or the workpiece  
immediately after operation; they may be  
extremely hot and could burn your skin.  
2. Always be sure you have a firm footing.  
Be sure no one is below when using the  
tool in high locations.  
7. Some material contains chemicals which  
may be toxic. Take caution to prevent dust  
inhalation and skin contact. Follow mate-  
rial supplier safety data.  
3. Hold the tool firmly.

OPERATION  
003080  
Holding tool  
When drilling a large hole with a hole saw, etc., the side grip  
(auxiliary handle) should be used as a brace to maintain safe  
control of the tool.  
Grasp the rear handle and the front grip firmly when starting  
or stopping the tool, since there is an initial and final reaction.

Holding against a stud  
When drilling action is forward (clockwise), the tool should be  
braced to prevent a counterclockwise reaction if the bit  
should bind. When reversing, brace the tool to prevent a  
clockwise reaction. If the bit must be removed from a partially  
drilled hole, be sure the tool is properly braced before revers-  
ing.

Drilling operation  
Drilling in wood  
When drilling in wood, the best results are obtained with  
wood drills equipped with a guide screw. The guide screw  
makes drilling easier by pulling the bit into the workpiece.  
Drilling in metal  
To prevent the bit from slipping when starting a hole, make  
an indentation with a center-punch and hammer at the point  
to be drilled. Place the point of the bit in the indentation and  
start drilling.  
Use a cutting lubricant when drilling metals. The exceptions  
are iron and brass which should be drilled dry.  
CAUTION:  
Pressing excessively on the tool will not speed up the  
drilling. In fact, this excessive pressure will only serve to  
damage the tip of your bit, decrease the tool  
performance and shorten the service life of the tool.  
8
 
There is a tremendous twisting force exerted on the tool/  
bit at the time of hole breakthrough. Hold the tool firmly  
and exert care when the bit begins to break through the  
workpiece.  
A stuck bit can be removed simply by setting the  
reversing switch to reverse rotation in order to back out.  
However, the tool may back out abruptly if you do not  
hold it firmly.  
Always secure small workpieces in a vise or similar hold-  
down device.  
Avoid drilling in material that you suspect contains  
hidden nails or other things that may cause the bit to  
bind or break.  
MAINTENANCE  
CAUTION:  
Always be sure that the tool is switched off and  
unplugged before attempting to perform inspection or  
maintenance.

Replacing carbon brushes  
Remove and check the carbon brushes regularly. Replace  
when they wear down to the limit mark. Keep the carbon  
brushes clean and free to slip in the holders. Both carbon  
brushes should be replaced at the same time. Use only iden-  
tical carbon brushes.

WARNING  
Some dust created by power sanding, sawing, grinding, drilling, and other  
construction activities contains 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 and other masonry products, and  
• 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.
