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.  
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.  
6. Do not expose power tools to rain or wet  
conditions. Water entering a power tool will  
increase the risk of electric shock.  
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  
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.  
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.  
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.

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  
USB003-2  
DO NOT let comfort or familiarity with product (gained from  
repeated use) replace strict adherence to 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 or  
its own cord. Contact with a livewire will  
make exposed metal parts of tool liveand  
shock the operator.  
4. Hold the tool firmly.  
5. Always be sure you have a firm footing.  
Be sure no one is below when using the  
tool in high locations.  
6. The proper fastening torque may differ  
depending upon the kind or size of the  
bolt. Check the torque with a torque  
wrench.  
2. Wear ear protectors.  
3. Check the socket carefully for wear,  
cracks or damage before installation.

Fastening time  
Hold the tool firmly and place the socket over the bolt or nut.  
Turn the tool on and fasten for the proper fastening time.  
NOTE:

The fastening torque is affected by a wide variety of factors  
including the following. After fastening, always check the  
torque with a torque wrench.  
1. Voltage  
Voltage drop will cause a reduction in the fastening  
torque.  
2. Socket  
Failure to use the correct size socket will cause a  
reduction in the fastening torque.  
A worn socket ( wear on the hex end or square end )  
will cause a reduction in the fastening torque.  
3. Bolt  
Even though the torque coefficient and the class of  
bolt are the same, the proper fastening torque will  
differ according to the diameter of bolt.  
Even though the diameters of bolts are the same, the  
proper fastening torque will differ according to the  
torque coefficient, the class of bolt and the bolt  
length.  
4. The use of the universal joint or the extension bar some-  
what reduces the fastening force of the impact wrench.  
Compensate by fastening for a longer period of time.  
5. The manner of holding the tool or the material of driving  
position to be fastened will affect the torque.  
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.
