SPECIFIC SAFETY
WARNING! DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence to the
tool safety rules. If you use this tool unsafely or incorrectly,
you can suffer serious personal injury.
WARNING! Only use impact sockets with the impact wrench.
Impact sockets have thicker walls and are made of ductile
material to handle vibration. Regular drive sockets may
rupture or explode under stress, injuring you or a bystander.
WARNING! Immediately release the trigger if the tool's bit
becomes stuck or jammed. The tool’s torque can twist your
arm and cause an injury. The tool may twist out of your grip
and cause an injury to yourself or a bystander.
1. Use the correct tool for the job. This tool was designed for a
specific function. Do not modify or alter this tool or use it for an
unintended purpose.
2. A loose or mismatched bit may be ejected by the tool, causing an
injury to the user or a bystander.
3. Always hold the tool firmly in your hands before switching the tool
ON. The reaction to the motor’s torque may cause the tool to twist,
as it accelerates to full speed.
4. Never attempt to change the impact socket's direction of rotation
while it is active. This can damage the interlock feature built into
the switch. Be sure the impact socket has completely stopped and
engage any safety features before changing the rotation direction.
Turn the power off as an added precaution.

5. Clean the impact wrench's air vents often. The motor’s fan
will draw dust and other particulates into the tool. Excessive
accumulation of wood, plastic or metal particulates can create a
fire or electrical hazard.
6. Inspect the tool components periodically. Repair or replace
damaged or worn components. Only use identical replacement
parts when servicing.
POWER TOOL PRECAUTIONS
1. Do not use any power tool with a malfunctioning power switch
or control. A power tool that fails to respond to the controls is
dangerous and can cause an injury. A qualified technician must
repair and verify the power tool is operating correctly, before it can
be used.
2. Shut the power off and disconnect the impact wrench from
the power supply (if possible) before making any adjustments,
changing accessories, cleaning, servicing or when storing. Such
preventive safety measures reduce the risk of starting the tool
accidentally.
3. Never force the tool. Excessive pressure could bend or break the
impact wrench, resulting in damage to the tool, your workpiece or
serious personal injury. If the impact wrench runs smoothly under
no load, but does not run smoothly under load, then excessive
pressure is being used.
4. Check if the impact wrench's moving parts are misaligned or
binding before each use. Correct the issue before using the impact
wrench to avoid an injury or damage to the tool.
5. Always be aware of the position of your hands relative to the
impact wrench. Avoid awkward hand positions where a sudden slip
could cause a hand to move into the impact socket. Never reach
behind or beneath the impact wrench.
6. Only use accessories that are specifically designed for use with
the impact wrench. Ensure the impact socket is tightly installed.
7. Only use an impact socket that exceeds the Speed rating (see
Specifications).
9067976 HEAVY DUTY ELECTRIC IMPACT WRENCH V1.0
Assistance available at www.princessauto.com or 1-800-665-8685 Page 6
8. Before using the impact wrench on a workpiece, test the impact
wrench by running it at the highest speed rating for at least
30 seconds in a safe position. Stop immediately if there is any
abnormal vibration or wobbling. Check the tool to determine the
cause.
9. Never touch the impact socket or workpiece during or immediately
after use. They may be hot and could inflict a burn injury.
10. Do not cover the air vents. Proper cooling of the motor is
necessary to ensure normal life of the tool.
11. Never use a tool with an impact socket that is cracked or worn.
Change the impact socket before using it.
12. Do not place the impact wrench down until the impact socket has
stopped moving. The impact wrench may catch the surface of work
material and wrench itself free, causing injury to the user or others
in the work area.
13. Never point the impact wrench towards yourself. It could inflict an
injury.
KICKBACK PRECAUTIONS
Kickback is a sudden reaction when the impact wrench snags or is
caught on the material. If kickback occurs:
•The impact socket may pass over a body part, causing an injury.
•The impact wrench may wrench the user’s arm causing muscle or
joint injuries.
•The tool may strike bystanders.
•Kickback can also damage the tool or workpiece.
Kickback can be avoided by taking proper precautions:
1. Maintain a firm grip on the tool and position your body and arms to
allow you to resist a kickback. Kickback will propel the tool in the
direction opposite the impact socket's direction of rotation. The tool
may pull out of your grasp.
a. Use clamps or a vice to hold down smaller workpieces.
2. Only use an impact socket designed for the tool.

ELECTRICAL SAFETY
WARNING! Do not touch or handle a live tool with any
part of your body that is wet or damp. Wet skin reduces
resistance to electrical current, increasing the danger of a
serious or fatal shock.
WARNING! To reduce risk of electric shock, be certain that
the plug is connected to a properly grounded receptacle.
1. Do not alter any parts of the tool or accessories. All parts and
accessories are designed with built-in safety features that may be
compromised if altered.
2. Protect yourself against electric shocks when working on electrical
equipment. Avoid body contact with grounded surfaces. There is
an increased chance of electrical shock if your body is grounded.
3. Do not expose the impact wrench to rain, snow, frost or any other
damp or wet conditions. Water entering a tool will increase the risk
of electric shock.
4. In the event of a power failure, turn off or unplug the machine
as soon as the power is interrupted. The possibility of accidental
injury could occur if the power returns and the unit is not switched
off.
5. Make certain the power source conforms to requirements of your
equipment (see Specifications).
6. This tool is only for use on 120 V (single phase) and is equipped
with a three-prong grounded power supply cord and plug. Check
with a qualified electrician if you are in doubt as to whether
the outlet is properly grounded. If the tool should electronically
malfunction or break down, grounding provides a low resistance
path to carry electricity away from the user.
a. Never remove the grounding prong or modify the plug in any
way, as this will render the tool unsafe.
b. Do not use any adapter plugs.
POWER CORD SAFETY
1. Insert the power cord plug directly to the power supply whenever

a. When operating a 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.
b. Use in conjunction with a Ground Fault Circuit Interrupter
(GFCI). It is recommended that the GFCI should have a rated
residual current of 30 mA or less.
2. Do not operate this tool if the power cord is frayed, damaged
or poorly spliced, as an electric shock may occur, resulting in
personal injury or property damage.
3. Discontinue use if a power cord feels more than comfortably warm
while operating the tool.
4. Keep all connections dry and off the ground to reduce the risk of
electric shock. Do not touch the plug or wiring with wet hands.
5. Prevent damage to the power cord by observing the following:
a. Place the power cord in a position that prevents it from coming
into contact with the tool or getting caught by the workpiece.
The cord should always stay behind the tool.
b. Do not pull on the cord to disconnect the plug from an outlet.
c. Keep the cord away from heat, oil, sharp edges or moving
parts.
6. Position the cord so it is not be stepped on, tripped over or
otherwise subjected to damage or stress.
7. Do not wrap the cord around the tool, as sharp edges may cut
insulation or cause cracks if wound too tight. Gently coil cord and
either hang on a hook or fasten with a device to keep cord together
during storage.
