a. Keep the work area clean and well
lighted. Cluttered benches and dark
areas increase the risks of electric
shock, re, and injury to persons.
b. Do not operate the tool in
explosive atmospheres, such as in
the presence of ammable liquids,
gases, or dust. The tool is able to
create sparks resulting in the ignition
of the dust or fumes.
c. Keep bystanders, children, and
visitors away while operating the

Page 3For technical questions, please call 1-800-444-3353.SKU 92421
tool. Distractions are able to result in
the loss of control of the tool.
Personal safety
a. Stay alert. Watch what you are
doing and use common sense
when operating the tool. Do not
use the tool while tired or under
the inuence of drugs, alcohol, or
medication. A moment of inattention
while operating the tool increases the
risk of injury to persons.
b. Dress properly. Do not wear loose
clothing or jewelry. Contain long
hair. Keep hair, clothing, and
gloves away from moving parts.
Loose clothes, jewelry, or long hair
increases the risk of injury to persons
as a result of being caught in moving
parts.
c. Avoid unintentional starting.
Be sure the switch is off before
connecting to the air supply. Do not
carry the tool with your nger on the
switch or connect the tool to the air
supply with the switch on.
d. Remove adjusting keys and
wrenches before turning the tool
on. A wrench or a key that is left
attached to a rotating part of the tool
increases the risk of personal injury.
e. Do not overreach. Keep proper
footing and balance at all times.
Proper footing and balance
enables better control of the tool in
unexpected situations.
f. Use safety equipment. A
dust mask, non-skid safety
shoes and a hard hat must
be used for the applicable
conditions. Wear heavy-duty work
gloves during use.
g. Always wear eye
protection. Wear ANSI-
approved safety goggles.
h. Always wear hearing
protection when using
the tool. Prolonged
exposure to high intensity
noise is able to cause hearing loss.
Tool use and care
a. Use clamps or another practical
way to secure and support the
workpiece to a stable platform.
Holding the work by hand or against
the body is unstable and is able to
lead to loss of control.
b. Do not force the tool. Use the
correct tool for the application. The
correct tool will do the job better and
safer at the rate for which the tool is
designed.
c. Do not use the tool if the Trigger
does not turn the tool on or off.
Any tool that cannot be controlled
with the switch is dangerous and
must be repaired.
d. Disconnect the tool from the
air source before making
any adjustments, changing
accessories, or storing the tool.
Such preventive safety measures
reduce the risk of starting the tool
unintentionally. Turn off and detach
the air supply, safely discharge any
residual air pressure, and release the
throttle and/or turn the switch to its off
position before leaving the work area.

f. Maintain the tool with care. A
properly maintained tool is easier to
control.
g. Check for misalignment or binding
of moving parts, breakage of
parts, and any other condition
that affects the tool’s operation. If
damaged, have tool serviced before
using. Many accidents are caused
by poorly maintained tools. There is a
risk of bursting if the tool is damaged.
h. Use only accessories that are
identied by the manufacturer for
the specic tool model. Use of an
accessory not intended for use with
the specic tool model, increases the
risk of injury to persons.
Service
a. Tool service must be performed
only by qualied repair personnel.
b. When servicing a tool, use only
identical replacement parts. Use
only authorized parts.
c. Use only the lubricants supplied
with the tool or specied by the
manufacturer.
Air source
a. Never connect to an air
source that is capable of
exceeding 90 psi. Over
pressurizing the tool may
cause bursting, abnormal operation,
breakage of the tool or serious injury
to persons. Use only clean, dry,
regulated compressed air at the rated
pressure or within the rated pressure
range as marked on the tool. Always
verify prior to using the tool that the
air source has been adjusted to the
rated air pressure or within the rated
air-pressure range.
b. Never use oxygen, carbon dioxide,
combustible gases or any bottled
gas as an air source for the tool.

1. Incorporate a lter, regulator with
pressure gauge, oiler, in-line shutoff
valve, and quick coupler for best
service, as shown in the diagram
above. An in-line shutoff ball
valve is an important safety device
because it controls the air supply
even if the air hose is ruptured.
The shutoff valve should be a ball
valve because it can be closed
quickly.
Note: If an automatic oiler system is not
used, add a few drops of Pneumatic
Tool Oil to the airline connection
before operation. Add a few more
drops after each hour of continual
use.
2. Attach an air hose to the
compressor’s air outlet. Connect the
air hose to the air inlet of the tool.
Other components, such as a coupler
plug and quick coupler, will make
operation more efcient, but are not
required.
WARNING! TO PREVENT SERIOUS
INJURY FROM ACCIDENTAL
OPERATION:
Do not install a female quick
coupler on the tool. Such a coupler
contains an air valve that will allow
the air tool to retain pressure and
operate accidentally after the air
supply is disconnected.
Note: Air ow, and therefore tool
performance, can be hindered by
undersized air supply components.
3. The air hose must be long enough
to reach the work area with enough
extra length to allow free movement
while working.
4. Release the tool’s Trigger (13); refer
to Operation section for description of
controls.
5. Close the in-line safety valve between
the compressor and the tool.
6. Turn on the air compressor according
to the manufacturer’s directions and
allow it to build up pressure until it
cycles off.
7. Adjust the air compressor’s output
regulator so that the air output is
enough to properly power the tool,
but the output will not exceed the
tool’s maximum air pressure at any
time. Adjust the pressure gradually,

Page 8 For technical questions, please call 1-800-444-3353. SKU 92421
while checking the air output gauge
to set the right pressure range.
8. Inspect the air connections for leaks.
Repair any leaks found.
9. If the tool will not be used at this
time, turn off and detach the air
supply, safely discharge any
residual air pressure, and release
the throttle and/or turn the switch to
its off position to prevent accidental
operation.
10. Drain the compressor regularly.
Note: Residual air pressure should not be
present after the tool is disconnected
from the air supply. However, it is a
good safety measure to attempt to
discharge the tool in a safe fashion
after disconnecting to ensure that the
tool is disconnected and unpowered.
Assembly
1. While main body of Impact Wrench
does come assembled, the Side
Handle (45) needs to be fastened to
the side of Hammer Case (43).
2. Attach Washers (46A) to Screws
(46). Position Handle (45) against
