GENERAL SAFETY RULES USA002-2
(For All Tools)
WARNING:
Read and understand all instructions. Failure to follow all
instructions listed below, may result in electric shock, fire and/or
serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
1. Keep your work area clean and well lit.
Cluttered benches and dark areas invite acci-
dents.
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 bystanders, children, and visitors
away while operating a power tool. Distrac-
tions can cause you to lose control.
Electrical Safety
4. 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 elec-
trician to install a polarized outlet. Do not
change the plug in any way. Double insula-
tion eliminates the need for the three wire
grounded power cord and grounded power
supply system.

5. Avoid body contact with grounded sur-
faces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of
electric shock if your body is grounded.
6. Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
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.
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.
Personal Safety
9. Stay alert, watch what you are doing and
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.
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.
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.
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.
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.
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.
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
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.
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.
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.
19. Store idle tools out of reach of children
and other untrained persons. Tools are
dangerous in the hands of untrained users.
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.
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.
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.

4
SERVICE
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.
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.
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 USB004-2
DO NOT let comfort or familiarity with product (gained from
repeated use) replace strict adherence to screwdriver 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 tool 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. Always be sure you have a firm footing.
Be sure no one is below when using the
tool in high locations.
3. Hold the tool firmly.
4. Keep hands away from rotating parts.
5. Do not touch the bit or the workpiece
immediately after operation: they may be
extremely hot and could burn your skin.

FUNCTIONAL
DESCRIPTION CAUTION:
•Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Depth adjustment
The depth can be adjusted by turning the locking sleeve.
Tu r n i t i n “A”direction for less depth and in “B”direction for
more depth. One full turn of the locking sleeve equals 1.5
mm (1/16”) change in depth.
Adjust the locking sleeve so that the distance between the tip of
the locator and the screw head is approximately 1 mm (3/64”)
as shown in the figures. Drive a trial screw into your material or
a piece of duplicate material. If the depth is still not suitable for
the screw, continue adjusting until you obtain the proper depth
setting.

range speed.
C range:
For regular fastening work.
NOTE:
•The above figure shows standard applications. They
may differ under certain conditions.
CAUTION:
•If the tool is operated continuously at low speeds for a
long time, the motor will get overloaded, resulting in tool
malfunction.
•The speed adjusting dial can be turned only as far as 5
and back to 1. Do not force it past 5 or 1, or the speed
adjusting function may no longer work.
Hook
The hook can be installed on either side of the tool. To change
the hook position, remove the thumb screw and hook. Replace
the hook so that its bent portion will be on the other side.
The space between the hook and the tool itself can be adjusted
to provide more 37 mm (1-7/16”) or less 17 mm (11/16”) room
for temporarily hanging the tool. To adjust, remove the thumb
screw and hook. Then use the other hole when securing with
the thumb screw.

OPERATION Fit the screw on the point of the bit and place the point of the
screw on the surface of the workpiece to be fastened. Apply
pressure to the tool and start it. Withdraw the tool as soon as
the clutch cuts in. Then release the switch trigger.
CAUTION:
•When fitting the screw onto the point of the bit, be careful
not to push in on the screw. If the screw is pushed in, the
clutch will engage and the screw will rotate suddenly.
This could damage a workpiece or cause an injury.
•Make sure that the bit is inserted straight in the screw
head, or the screw and/or bit may be damaged.
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.
Use a screwdriver to remove the brush holder caps. Take out
the worn carbon brushes, insert the new ones and secure
the brush holder caps.
To maintain product SAFETY and RELIABILITY, repairs, car-
bon brush inspection and replacement, any other mainte-
nance or adjustment should be performed by Makita
Authorized or Factory Service Centers, always using Makita
replacement parts.
