PERSONAL SAFETY
1. Use eye, face, head, breathing and ear 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 ANSI approved earplugs.
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. Dress properly, wear protective equipment. Do not wear loose clothing or jewelry as they can be caught in
moving parts. Tie back long hair. Protective, electrically non-conductive clothes and non-skid footwear are
recommended when working.
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.
SPECIFIC SAFETY PRECAUTIONS
1. Do not over-tighten nuts. They could shatter and cause damage to the tool or workpiece 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. Remove adjusting keys and wrenches. Check that keys and adjusting wrenches are removed from the tool or
machine before connecting it. A wrench or key that is left attached to a rotating part of the tool increases the
risk of personal injury.
5. Avoid unintentional starts. Be sure that the throttle is in neutral position when not in use and before connecting it
to any air source. Do not carry the tool with fingers near or on the switch.
6. 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.
7. When not in use for an extended period, apply a thin coat of lubricant to the steel parts to avoid rust.
8. Maintain label and name plate on the tool. These carry important information. If unreadable or missing,
contact Princess Auto for a replacement.
SERVICE
1. When servicing, use only identical replacement parts. Only use accessories intended for use with this tool.
2. For your safety, service and maintenance should be performed regularly by a qualified technician.

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 this tool is 1/2" I.D.
with a 3/8” NPT air inlet.
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 air line.
7. Drain the air tank daily. Water in the air line will damage the tool.
8. Clean air inlet filter weekly.
9. Avoid using an unnecessarily long air hose. Choose a hose that is appropriate for the situation, as a hose that
is too long and running across the floor can be more dangerous than helpful.
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 8 metres). 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 (eg. 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.

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
air tool oil in the air inlet then run the tool under no load until exhaust is clear to remove packing grease. To
maintain, add only one or two drops 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 air line lubricator filled and correctly adjusted. The in-line lubricator 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. The tool then has 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.
INSTALLATION
SOCKET INSTALLATION
Turn off the air compressor and disconnect the air hose when changing sockets. After attaching the socket, attach the
air hose and turn the air compressor on.
The working torque of the impact wrench is 750 ft-lb. Make sure that the nut or bolt you are using the tool to tighten
can withstand the rated torque and is rated for 6,500 RPM or greater. If available, check the recommended torque
specifications for the nut.
1. Select the appropriately sized 1” drive impact socket for the job.
N.B. Only use impact sockets which are specifically designed for use with a impact wrench.
Do not use worn or damaged sockets.
2. Push and snap the socket (not included) onto the anvil.
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 impact 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 arrow on the regulator to increase the power. Turn it
toward the 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 workpiece 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.
