is in the neutral or OFF position when not in use and before
connecting it to any air source.
6. Securely hold this tool using both hands. Using a tool with only one
hand can result in loss of control.
SPECIFIC SAFETY PRECAUTIONS
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. Do not cool the impact socket with any liquid when hot. This can
damage the the impact socket by weakening the material, making
the accessory unsafe for use.
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. 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.
4. 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.
5. Only use accessories that are specifically designed for use with
the impact wrench. Ensure the impact socket is tightly installed.
6. Only use an impact socket that exceeds the Speed rating and
impact rating (see Specifications).
7. 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
9058421 COMPOSITE AIR IMPACT WRENCH V1.0
Assistance available at www.princessauto.com or 1-800-665-8685 Page 6
abnormal vibration or wobbling. Check the tool to determine the
cause.
8. Never touch the impact socket or workpiece during or immediately
after use. They may be hot and could inflict a burn injury.
9. Never use an impact wrench with an impact socket that is cracked
or worn. Change the impact socket before using it.
10. 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.
11. Avoid unintentional starts. Be sure that the regulator/throttle switch
is in the neutral or OFF position when not in use and before
connecting it to any air source.
12. Never point the impact wrench towards yourself. It could inflict an
injury.
KICKBACK PRECAUTIONS
Kickback is a sudden reaction when an impact socket snags or is
caught on the material. If kickback occurs:
•The impact socket may contact a body part, causing a serious
injury
• 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.
3. Maintain control of a long workpiece or large panel by placing
supports under the material on either side of the impact wrench.
AIR TOOL PRECAUTIONS
1. Use only clean and dry compressed air as a power source.
Contaminated or moist air will gradually damage the tool.
V1.0 COMPOSITE AIR IMPACT WRENCH 9058421
Page 7 Assistance available at www.princessauto.com or 1-800-665-8685
2. Install an in-line shutoff valve or regulator to allow immediate
control over the air supply in an emergency, even if a hose is
ruptured.
3. Discontinue tool use if it does not work properly or air is leaking.
Tag or mark the tool as ‘defective’ or ‘out of service’ until repaired.
4. Check the manufacturer’s maximum pressure rating for air tools
and accessories. Compressor outlet pressure must be regulated
to never exceed the maximum pressure rating of the tool (see
Specifications). Exceeding the maximum PSI rating can create a
bursting hazard, causing injury and property damage.
a. The tool does not regulate the pressure level. The power
output is in direct proportion to the air pressure available. An
external air pressure regulator is required to safely use this
tool.
5. Attach all accessories properly to the tool before connecting the air
supply. A loose accessory may detach or break during operation.
6. Never use oxygen, combustible gas or any other bottled gas as
a power source. Any power source other than an air compressor
could cause an explosion and serious personal injury.
7. Turn OFF the valve and discharge any remaining air pressure after
each use or before adjusting the tool.
8. Do not leave the air tool unattended with its compressed air supply
on. Turn off the compressed air supply and bleed the air tool of any
remaining compressed air before leaving the air tool unattended.
9. Serious injury may occur from loose debris being propelled at
high speeds from the compressed air stream. Always wear OSHA
approved safety glasses to protect the eyes during operation of the
air compressor.
10. Never point the air stream or tool at any point of your body, other
people or animals. Debris and dust ejected at high speed can
cause an injury.
11. Always turn off the air compressor and drain tank pressure
completely before attempting maintenance or attaching air tools.
Release pressure slowly from the system.
12. Do not cover the air vents.

AIR HOSE PRECAUTIONS
1. Inspect the tool's air hose for cracks, fraying or other faults before
each use. Discontinue use if the air hose is damaged or hissing
is heard from the air hose or couplers. Replace the defective air
hose.
2. Do not allow people, mobile equipment or vehicles to pass over the
unprotected air hose. Position the air hose away from high traffic
areas, in a reinforced conduit or place planks on both sides of the
air hose to create a protective trench.
3. Prevent damage to the air hose by observing the following:
a. Never carry the tool by the air hose.
b. Keep the air hose behind the tool and out of the tool's work
path.
c. Keep the air hose away from heat, oil, sharp edges or moving
parts.
d. Do not wrap the air hose around the tool as sharp edges may
pierce or crack the air hose. Gently coil the hose and either
hang on a hook or fasten with a device to keep hose together
when storing.
4. A damaged or disconnected air hose under pressure may whip
around and inflict personal injury or damage the work area. Secure
the compressor's air hose to a fixed or permanent structure with
clamps or cable ties.
