PERSONAL SAFETY
1. Dress properly, wear protective equipment. Use breathing, ear, eye, face, foot, hand and head protection.
Always wear ANSI approved impact safety goggles, which must provide both frontal and side protection.
Protect your hands with suitable gloves. Protect your head from falling objects by wearing a hard hat. Wear
an ANSI approved dust mask or respirator when working around metal, wood and chemical dusts and mists.
Wear ANSI approved earplugs. Protective, electrically non-conductive clothes and non-skid footwear are
recommended when working. Wear steel toed boots to prevent injury from falling objects.
2. Do not over reach; keep proper footing and balance at all times. Proper footing and balance enables better
control of the tool in unexpected situations.
3. Keep any articles of clothing, jewelry, hair etc. away from moving parts. These can be caught in moving
parts, resulting in damage to the tool and/or serious injury.
4. Stay alert, watch what you are doing and use your common sense. Do not operate any machine or tool when
you are tired, under the influence of drugs, alcohol or medications.
5. Use clamps or other practical ways to secure and support the work piece to a stable platform.
Holding the work piece by hand or against your body is unstable and may lead to loss of control.
VIBRATION PRECAUTIONS
This tool vibrates during use. Repeated or long-term exposure to vibration may cause temporary or permanent
physical injury, particularly to the hands, arms and shoulders.
1. Anyone using vibrating tools regularly or for an extended period should first be examined by a doctor and
then have regular medical check ups to ensure medical problems are not being caused by or worsened from
tool use. Pregnant women or people who have impaired blood circulation to the hands, past hand injuries,
nervous system disorders, diabetes or Raynaud's Disease should not use this tool. If you feel any medical
symptoms related to vibrations (such as tingling, numbness, and white or blue fingers), seek medical
attention as soon as possible.
2. Do not smoke during use. Nicotine reduces the blood flow to the hands and fingers, increasing the risk of
vibration-related injury.
3. Wear suitable gloves to reduce the vibration effects on the user.
4. Use tools with the lowest amount of vibration when there is a choice between different processes.
5. Do not use for extended periods. Take frequent breaks when using this tool.
6. Let the tool do the work. Grip the tool as lightly as possible (while still keeping safe control of it).
7. To reduce vibrations, maintain tool as explained in this manual. If abnormal vibrations occur, stop using this
tool immediately.
8. This tool will not stop moving immediately. Do not lay the tool down or leave it unattended until it has come
to a complete stop. A part that is moving could make the tool jump or grab a surface and pull the tool out of
your control.

SPECIFIC SAFETY PRECAUTIONS
1. Do not over-tighten nuts. They could shatter and cause damage to the tool or work piece or cause serious
injury. Use a torque wrench to torque the nut after using the impact wrench.
2. Do not use any additional force upon the wrench in order to remove a nut.
3. Do not allow wrench to run without load for an extended period of time as this will shorten its life.
4. This impact wrench should only be used with impact sockets and extensions. Use of other accessories
can cause them to break, causing permanent damage to the unit and severe injury to the operator.
TOOL USE AND CARE
1. Use the right tool for the job. Do not attempt to force a small tool or attachment to do the work of a larger
industrial tool. The tool will perform better and more safely at the task for which it was intended.
Do not modify this tool or use for a purpose for which it was not designed.
2. Securely hold this tool using both hands. Using tools with only one hand can result in loss of control.
3. Maintain tools with care. Keep tools clean and in good condition for a better and safer performance.
Follow instructions for lubricating and changing accessories. Inspect tool fittings, alignment and hoses
periodically and, if damaged, have them repaired by an authorized technician or replaced. The handles must
be kept clean, dry and free from oil and grease at all times. A properly maintained tool reduces the risk of
binding and is easier to control. Applying excessive force can lead to slips and damage to your work or
personal injury.
4. Avoid unintentional starts. Be sure that the throttle is in neutral when not in use and before connecting it to
any air source. Do not carry the tool with fingers near or on the switch.
5. Only use the lubricants supplied with the tool or specified by the manufacturer. Other lubricants may not be
suitable and may damage the tool or even make the tool explode.
6. When not in use for an extended period, apply a thin coat of lubricant to the steel parts to avoid rust.
7. Maintain the label and name plate on the tool. These carry important information. If unreadable or missing,
contact Princess Auto for a replacement.

AIR SOURCE
1. Disconnect air supply. Disconnect tools from air
pressure source when not in use, before cleaning,
servicing or changing a piece or accessory. After
disconnecting, discharge any residual air pressure.
2. Do not use tools if the trigger switch does not function
properly. Any tool that cannot be controlled with the
ON/OFF switch is dangerous and must be repaired.
3. Use proper size and type of air pressure line and fittings.
The recommended air line for a tool with a 1/2" inlet
is 1/2" I.D.
4. Always verify prior to using a tool that the air source
has been adjusted to the rated air pressure or within the
rated air-pressure range. Over pressurizing a 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 range as marked
on the tool.
5. Never use pure oxygen, carbon dioxide, combustible gases or any bottled gas as an air source for a tool.
Such gases are capable of causing an explosion and serious injury to persons. Do not use an air source
besides an air compressor to power this tool.
6. Always use an air regulator, an in-line filter and a moisture trap in your compressed air system. These
accessories will increase the tool's life and keeps the tool in good working condition. See the diagram above
for recommended components of an airline.
7. Drain the air tank daily. Water in the airline will damage the tool.
8. Clean air inlet filter weekly.
9. Avoid using too long of an air hose. The longer the hose, the lower the pressure will be at the end of the
hose, to the point that it may not meet the minimum required for the tool. As well, a longer hose can
become a tripping hazard.
10. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections
are secure.
11. Always carry a tool by its handle; never carry the tool by the air hose.
12. Line pressure should be increased to compensate for unusually long air hoses (over 26 ft). The hose
diameter should be 1/2" l.D.
13. Air tool CFM consumption ratings are based upon a 25% duty cycle. If you require continuous duty, a
larger compressor will be required (e.g. 4.0 CFM tool at continuous duty requires 16.0 CFM to function at
maximum torque).
For best service, incorporate an oiler, regulator and inline filter as shown in the diagram above.

AIR SOURCE INSTALLATION
1. Set the air pressure regulator on the air compressor to 90 PSI. Do not exceed the tool's recommended
air pressure. Excess pressure could result in damage to the tool, to your work piece or serious injury.
2. Prepare a standard 1/2" air connector for use with your tool. Wrap the threaded portion of the air connector
with thread tape. Attach it to the tool's air inlet. Tighten securely.
3. Attach a standard quick connector to the air source's hose. Attach the air hose to the tool.
Note: If you are not using an in-line oiler, add a few drops of air tool oil in the tool's air inlet before use.
In the same manner, add a few drops after every hour of use.
4. Check the air line and its connections for air leaks. Do not use this tool until you have repaired all air leaks.
Note: Turn off the air compressor, disconnect the air pressure hose and discharge any residual pressure
inside the tool before changing accessories or making any adjustments to the tool. Failure to do so could
result in severe injury, tool or property damage.
LUBRICATION
1. All air tools are packed in grease to prevent corrosion of internal parts during shipping and storage.
We recommend you clean this out to have optimum performance from your new air tool. Add a generous
amount of air tool oil in the air inlet, and then run the tool under no load until exhaust is clear to remove
packing grease. For future maintenance, add only one or two drops of oil daily.
2. It is very important that the tool be properly lubricated. Without proper lubrication, the tool will not work
properly and parts will wear prematurely. Manually dropping a drop or two of air tool oil once a day into the
tool's male connector is better than using an automatic in-line lubricator, which should only be required
when there are multiple users of the same tool.
3. Keep the in-line lubricator filled and correctly adjusted. It should be regularly checked and filled with air tool
oil. Proper adjustment of the in-line lubricator is performed by placing a sheet of paper next to the exhaust
ports and holding the throttle open approximately 30 seconds. The lubricator is properly set when a light
stain of oil collects on the paper. Excessive amounts of oil should be avoided.
4. Air tool oil is the only recommended lubricant for use in all air tools. Do not try to use other types of
lubricants to oil your tools. Using the wrong lubricant will cause premature tool failure and/or loss of power.
Use only recommended lubricants, specially made for pneumatic applications. Substitutes may harm the
rubber compounds in the tool's O-rings and other rubber parts.
5. Oiling your air tool regularly is important, but it is also important not to over oil your air tool. Over oiling
can cause premature tool failure. Your tool may not be ruined, but it will begin to experience loss of power
that will continually get worse until it no longer works, at which point the tool will have to be taken apart and
cleaned of excess oil.

6. In the event that it becomes necessary to store the tool for an extended period of time (overnight,
weekend, etc.), it should receive a generous amount of lubrication at that time. The tool should be run for
approximately 30 seconds to ensure oil has been evenly distributed throughout the tool. The tool should be
stored in a clean and dry environment.
WARNING! NEVER use WD-40 to clean or lubricate your air tool. WD-40 is a solvent that will break down the
internal grease and cause the air tool to seize up.
UNPACKING
1. Carefully remove the parts and accessories from the box.
2. Make sure that all items listed in the parts lists are included.
3. Inspect the parts carefully to make sure the tool was not damaged while shipping.
4. Do not discard the packaging material until you have carefully inspected and satisfactorily operated the tool.
WARNING! If any part is missing, do not operate the tool until the missing parts are replaced. Failure to do so
could result in serious personal injury.
OPERATION
WARNING! This tool generates considerable torque when in use. Always hold the tool with both hands when
using, and brace yourself to resist the torque which will be delivered to the work piece.
1. Tighten the nut as far as you can by hand before using the impact wrench.
2. Connect the wrench to the air hose.
3. Place the socket on the nut and grip the impact wrench tightly with both hands. Press the trigger to start
the tool.
Note: If the tool stalls while tightening, do not raise the outlet pressure of the air compressor above 90 PSI.
4. Set the reverse lever to the left, so that the anvil turns clockwise (forward.)
5. Place the socket over the fastener, grip the impact wrench firmly with both hands and gently squeeze
the trigger.
6. Turn the air regulator in the direction indicated by the H arrow on the regulator to increase the power.
Turn it toward the L arrow to decrease the power.
Note: If the impact wrench does not tighten the fastener to your satisfaction, do not raise the air pressure
on the compressor over 90 PSI. Pressures above 90 PSI will strip the work piece and damage the tool,
potentially causing tool failure and serious injury. Use other appropriate methods and tools to tighten
the nut.
7. When the fastener is tightened, release the trigger and remove the tool and socket.
8. Use a mechanical torque wrench to check fastener torque.
9. To loosen, set the reverse lever to the right, so that the anvil turns counterclockwise (reverse).
10. When finished with the tool, turn off the air compressor, disconnect the air hose and discharge any residual
air remaining in the tool. Put the impact wrench away in a safe storage area.
