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. 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, jewellery, 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.
6. 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.
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.
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 ratchet.
2. Do not use any additional force upon the ratchet in order to remove a nut.
3. Do not allow ratchet to run without load for an extended period of time as this will shorten its life.

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. 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.
3. Avoid unintentional starts. Be sure that the switch is in neutral or OFF 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.
4. 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.
5. When not in use for an extended period, apply a thin coat of lubricant to the steel parts to avoid rust.
6. 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 1/4" inlet is
3/8" 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.
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. 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 8 metres). The hose
diameter should be 3/8" I.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).
See the diagram above for recommended components of an air line.

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 1/4" 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
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.
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 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, 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.
