GENERAL SAFETY RULES
USA003-1
(FOR All BATTERY OPERATED 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

Wor k Area
1. Keep your work area clean and well lit.
Cluttered benches and dark areas invite accidents.
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. A battery operated tool with integral batteries or a separate battery pack must be
recharged only with the specified charger
for the battery. A charger that may be suit-
able for one type of battery may create a risk
of fire when used with another battery.
5. Use battery operated tool only with specifically designated battery pack. Use of any
other batteries may create a risk of fire.
Personal Safety
6. 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.
7. 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.
8. Avoid accidental starting. Be sure switch
is in the locked or off position before
inserting battery pack. Carrying tools with
your finger on the switch or inserting the battery pack into a tool with the switch on invites
accidents.
9. 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.
10. Do not overreach. Keep proper footing
and balance at all times. Proper footing and
balance enable better control of the tool in
unexpected situations.
11. 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
12. 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.
13. 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.
14. Do not use tool if switch does not turn it
on or off. A tool that cannot be controlled
with the switch is dangerous and must be
repaired.
15. Disconnect battery pack from tool or
place the switch in the locked or off position before making any adjustments,
changing accessories, or storing the tool.
Such preventive safety measures reduce the
risk of starting the tool accidentally.
16. Store idle tools out of reach of children
and other untrained persons. Tools are
dangerous in the hands of untrained users.
17. 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 connection from one terminal to another.
Shorting the battery terminals together may
cause sparks, burns, or a fire.
18. Maintain tools with care. Keep cutting
tools sharp and clean. Properly maintained
tools with sharp cutting edge are less likely to
bind and are easier to control.

19. 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.
20. Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitable for
one tool may create a risk of injury when
used on another tool.
SERVICE
21. Tool service must be performed only by
qualified repair personnel. Service or main-
tenance performed by unqualified personnel
may result in a risk of injury.
22. 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
shock or injury.
SPECIFIC SAFETY RULES
USB025-2
DO NOT let comfort or familiarity with product (gained from
repeated use) replace strict adherence to cordless impact
wrench 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.
Contact with a “live” wire will also make
exposed metal parts of the tool “live” and
shock the operator.
2. Be aware that this tool is always in an
operating condition, because it does not
have to be plugged into an electrical outlet.
3. Wear ear protectors.
4. Check the socket carefully for wear,
cracks or damage before installation.
5. Hold the tool firmly.
6. Always be sure you have a firm footing.
7. Be sure no one is below when using the
tool in high locations.
8. The proper fastening torque may differ
depending upon the kind or size of the
bolt. Check the torque with a torque
wrench.
