IMPORTANT SAFETY INFORMATION
1. Keep work area clean. Cluttered areas invite injuries.
2. Observe work area conditions. Do not use machines or power tools in damp or wet
locations. Don’t expose to rain. Keep work area well lighted. Do not use electrically
powered tools in the presence of flammable gases or liquids. Do not bring combustible
materials near the tools.
3. As with any tool, use common sense when operating. Do not wear loose clothing or
jewelry that could become caught by moving parts, causing injury. Operate tool a safe
distance from yourself and others in the work area.
4. Keep children away. Children must never be allowed in the work area. Do not let them
handle machines, tools, hoses or extension cords.
5. Store idle equipment. When not in use, tools must be stored in a dry location to inhibit
rust. Always lock up tools and keep out of reach of children and other untrained
persons. Switch off all unused electrical tools when stored. Tools are dangerous in the
hands of untrained users.
6. Always wear approved eye protection when using tools. If raising dust, wear a suitable
mask.
7. Work Safe. When wearing gloves to operate the tool, make sure that the gloves do not
interfere with operating the Trigger. Test your gloves with the Trigger before attaching
the unit to an air source. Keep your finger away from the Trigger until you are ready to
work. Never start the tool unless you have a firm grip with both hands and you are
positioned at your work piece or area. Before using the tool, know what is directly
underneath the work area or work piece. The tool can quickly penetrate material. If
working directly on the ground, make sure you are not directly above shallow cables,
lines, or pipes. Keep your limbs and body clear of the tool. If an accessory or
attachment breaks off, the tool tends to surge forward suddenly. Operate tool a safe
distance from yourself and others in the work area. Make sure the immediate area is
clear of other people or animals. Spectators must stay at a safe distance. Never point
the tool or the air hose (not included) at anyone. Keep proper footing and balance at
all times. Do not reach over or across running machines, hoses, etc.
8. Do not operate any tool if under the influence of alcohol or drugs. Read warning labels
on prescriptions to determine if your judgment or reflexes are impaired while taking
drugs. If there is any doubt, do not operate any tool.
9. Be sure air is in OFF position when connecting tool to air supply.
10. Use only those accessories that are designed for use with tools. For example, with
impact wrenches do not use ordinary sockets. Use impact sockets for all air tools.
11. Be sure to disconnect tool from air supply before changing accessories, performing
service on tool and when not in use.
12. Follow air source manufacturers' directions for connection of regulators, filters, and
other accessories to air source. Do not install quick couplers directly on tool as they
put unnecessary strain on the air inlet threads possibly causing them to wear out
prematurely. Instead, install them on a short length of air hose attached to the tool.
WARNING!
READ, UNDERSTAND AND FOLLOW ALL INSTRUCTIONS AND
WARNINGS BEFORE OPERATING THIS TOOL. FAILURE TO DO
SO MAY RESULT IN PERSONAL INJURY AND/OR PROPERTY
DAMAGE AND WILL VOID WARRANTY.

1. To set the tool to desired torque, select a nut or screw of known tightness of the same
size, thread pitch and thread condition as those on the job.
2. Turn air regulator to low position, apply wrench to nut and gradually increase power (turn
regulator to admit more air) until nut moves slightly in the direction it was originally set.
The tool is now set to duplicate that tightness, note regulator setting for future use.
3. When tightening nuts not requiring critical torque values, run nut up flush and then
tighten an additional one quarter to one-half turn (slight additional turning is necessary if
gasket are being clamped).
4. For additional power needed on
disassembly work, turn regulator to its
fully open position. This impact wrench
is rated at 5/8 USS bolt size. Rating
must be down graded for spring U
bolts, tie bolts, long cap screws,
double depth nuts, badly rusted
conditions and spring fasteners as
they absorb much of the impact power.
When possible, clamp or wedge the
bolt to prevent spring back.
5. Soak rusted nuts in penetrating oil and
break rust seal before removing with
impact wrench. If nut does not start to
move in three to five seconds use a
larger size impact wrench. Do not use
impact wrench beyond rated capacity
as this will drastically reduce tool life.
Oil tool before each use. 4 to 5 drops of a good grade Air Tool Oil placed in the air inlet is
sufficient. Use proper air pressure and CFM rating listed for this tool.
Drain water from hoses and compressor tank. Water in the air supply line will cause
gumming and loss of power. Clean the air filter on the supply line and flush the tool with
gum solvent or a 50/50 mix of air tool oil and kerosene. It may be necessary to
disassemble the tool to properly clean and re-lubricate.

IMPORTANT SAFETY INFORMATION
ASSEMBLY / INSTALLATION
1. You will need to prepare the 1/4" Quick-disconnect Coupler Plug to connect to the air
inlet on the impact wrench. Wrap the Coupler Plug with pipe thread seal tape before
threading it into the Air Inlet. Connect the a Quick-Disconnect coupler on a 3/8 in. ID Air
Source Hose to the tool.
Note: If you are not using an automatic oiler system, before operation, add a few drops of
Pneumatic Tool Oil to the airline connection. Add a few drops more after each hour of
continual use.
2. Set the air pressure on your compressor to 90 PSI. Do not exceed the recommended air
pressure of 90 PSI.
3. Check the air connection for leaks. Once you are satisfied there are no leaks, turn off the
air compressor and disconnect the tool.
Clean air of correct air pressure is recommended for the power supply for this tool. A
maximum of 90 PSI at the tool is recommended for most air tools of this class. Check
specifications section for recommended pressure. (Depending on length of air hose and
other circumstances, air pressure at compressor may need to be increased to 100 PSI to
ensure 90 PSI at the tool.)
Water in the air hose and compressor tank contributes to reduced performance and
damage of the air tool. Drain the air tank and filters before each use and as necessary to
keep the air supply dry.
Hose length over 25 ft. causes loss in line pressure. Increase hose I.D. or increase
compressor pressure to compensate for the pressure loss. Use an in-line pressure
regulator with gauge if air inlet pressure is critical.
AIR SOURCE
13. Check for damaged parts. Before using any tool, any part that appears damaged
should be carefully checked to determine that it will operate properly and perform its
intended function. Check for alignment and binding of moving parts; any broken parts
or mounting fixtures; and any other condition that may affect proper operation. Any
part that is damaged should be properly repaired or replaced by a qualified technician.
14. Maintenance. For your safety, maintenance should be performed regularly by a
qualified technician using original PERFORMANCE TOOLS® replacement parts.
Failure to do so can lead to accidents for the operator. Use of any other parts will void
the warranty. Only use accessories intended for use with this tool. Approved
accessories are available from Performance Tool®. Use only accessories that are
recommended by the manufacturer for your model. Accessories that may be suitable
for one tool may become hazardous when used on another tool.
