TOOL USE AND CARE
1. Use the correct tool for the job. Do not force a tool or attachment to do the work of a larger
industrial tool. Maximize tool performance and safety by using the tool for its intended task.
2. This tool was designed for a specific function. Do not modify or alter this tool or use it for an
unintended purpose.
3. Securely hold this tool using both hands, unless it is designed for single hand use. Using a tool
with only one hand can result in loss of control.
4. Maintain tools with care (see Maintenance).
5. Remove adjusting keys and wrenches from the tool before operation or connecting it to a power
source. A wrench or key that is left attached to a rotating part of the tool increases the risk of
personal injury.
6. Avoid unintentional starts. Be sure that the throttle/ignition switch is in the neutral or OFF
position when not in use and before connecting it to any power source.
7. Do not carry the tool with fingers near or on the trigger/switch.
AIR COMPRESSOR
Ensure the compressor used with the tool can supply the required Cubic Feet per Minute at the required
PSI (see Specifications).
1. Use proper size and type of air pressure line and fittings.
2. Use only clean, dry, regulated compressed air at the rated range as marked on the tool.
CAUTION! Do not use an air source other than an air
compressor to power this tool.
3. 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 for
recommended components of an air line.

8For technical questions call: 1-800-665-8685
8344103V 2.0
4. Avoid using an air hose that is too long. The longer the hose, the lower the pressure that
reaches the tool, possibly causing it to cease functioning. As well, a longer hose can become a
tripping hazard.
5. Air tool CFM consumption ratings are based upon a 25% duty cycle. If you require continuous
duty, a larger compressor is required.
AIR SOURCE INSTALLATION
WARNING! 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.
1. Set the air pressure regulator on the air compressor to the recommended PSI level (see
Specifications). Do not exceed the tool recommended air pressure. Excess pressure could
result in damage to the tool, to your workpiece or serious injury.
2. Prepare a standard 1/4 in. air connector for use with your tool. Wrap the threaded portion of
the air connector with thread seal tape. Wrap in a clockwise direction so it will not unravel when
attaching to a quick connector. Attach it to the tool air inlet and tighten.
3. Attach a standard quick connector to the air source’s hose. Attach the air hose to the tool’s air
connector.
4. Check the air line and its connections for air leaks. Do not use the tool until you have repaired
all air leaks.
DISCONNECTING AIR SOURCE
WARNING! Failure to follow these steps could result in severe injury, tool or property damage.
Disconnect tool from air source before cleaning, servicing, changing parts/accessories or when not in
use.
1. Turn the air regulator to the OFF or L position.
2. Turn off the air compressor.
3. Disconnect the air pressure hose.
4. Discharge any residual pressure inside the tool.
AIR TOOL LUBRICATION
CAUTION! NEVER use a penetrating oil to lubricate the tool. Penetrating oil may act as a solvent that
will break down the grease and cause the tool to seize up.

3/8 in. dr Composite Air Ratchet

Visit www.princessauto.com for more information
8344103 V 2.0
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.
2. It is very important that the tool is lubricated. Without lubrication, the tool will not work
properly and parts will wear prematurely. Manually adding a drop or two of air tool oil into the
tool’s male connector once a day is better than using an automatic in-line lubricator. In-line
lubricators should only be required when there are multiple users of the same tool.
3. Air tool oil is the only recommended lubricant for use in all air tools. Do not use other types
of lubricants to oil your tools. Using the wrong lubricant will cause premature tool failure and/
or loss of power. Substitutes may harm the rubber compounds in the tool’s O-rings and other
seals.
4. Keep the airline 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.
5. Avoid adding too much air tool oil during normal use. Too much oil can cause premature power
loss and eventual tool failure. The tool will need to be taken apart by a qualified technician 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.
UNPACKING
1. Carefully remove the parts and accessories from the box. Retain packaging material until you
have carefully inspected and satisfactorily installed or operated the tool.
2. Make sure that all items in the parts list are included.
3. Inspect the parts carefully to make sure the tools and accessories were not damaged while
shipping.
WARNING! Do not operate the tool if any part is missing. Replace the missing part before operating.
Failure to do so could result in a malfunction and serious personal injury.

CAUTION! Only qualified service personnel should repair the tool.
LUBRICATION
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 cause a malfunction during use.
CAUTION! NEVER use a penetrating oil to lubricate. Penetrating oils can act as a solvent that will
break down the grease and may cause the tool to seize up.
1. Use an air line lubricator with air tool oil adjusted to two (2) drops per minute.
2. If an air line lubricator cannot be used, add air motor oil to the inlet once per day.
