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

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.

•
•
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.

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.
MAKITA LIMITED ONE YEAR WARRANTY
Warranty Policy
Every Makita tool is thoroughly inspected and tested before leaving the factory. It is warranted to be free of
defects from workmanship and materials for the period of ONE YEAR from the date of original purchase.
Should any trouble develop during this one-year period, return the COMPLETE tool, freight prepaid, to one of
Makita's Factory or Authorized Service Centers. If inspection shows the trouble is caused by defective
workmanship or material, Makita will repair (or at our option, replace) without charge.
This Warranty does not apply where:
• repairs have been made or attempted by others:
• repairs are required because of normal wear and tear:
• the tool has been abused, misused or improperly maintained:
• alterations have been made to the tool.
IN NO EVENT SHALL MAKITA BE LIABLE FOR ANY INDIRECT, INCIDENTAL OR CONSEQUENTIAL
DAMAGES FROM THE SALE OR USE OF THE PRODUCT. THIS DISCLAIMER APPLIES BOTH DURING
AND AFTER THE TERM OF THIS WARRANTY.
MAKITA DISCLAIMS LIABILITY FOR ANY IMPLIED WARRANTIES, INCLUDING IMPLIED WARRANTIES OF
"MERCHANTABILITY" AND "FITNESS FOR A SPECIFIC PURPOSE," AFTER THE ONE-YEAR TERM OF
THIS WARRANTY.
This Warranty gives you specific legal rights, and you may also have other rights which vary form state to state.
Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above
limitation or exclusion may not apply to you. Some states do not allow limitation on how long an implied
warranty lasts, so the above limitation may not apply to you.
