10. Use an appropriate dust respirator when working for an
extended period of time. This will help prevent breathing in the
fine dust created while working.
WARNING! Dust that is created by power sanding, sawing, grinding,
drilling, and other construction activities may contain chemicals
that are known to cause cancer, birth defects, or other genetic
abnormalities. The level of risk from exposure to these chemicals
varies, according to how often this type of work is performed. In
order to reduce exposure to these chemicals, work in a well-
ventilated area, and use approved safety equipment, such as a dust
mask that is specifically designed to filter out microscopic particles.
11. Always make sure the work surface is free from nails and other
foreign objects.

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.

SANDING DISCS
The 6 in. diameter pressure sensitive adhesive sandpaper discs (sold
separately) attach to the backing pad (30), just press the sanding
disc onto the backing pad (30).
CAUTION! Disconnect the air supply when replacing the sand paper
or backing pad.
OPERATION
SANDING DISCS
Selecting the correct size and type of abrasive grit is extremely
important in achieving a high quality sanded finish. Aluminum oxide,
silicon carbide and other synthetic abrasive are best for power
sanding. To produce the best finish possible, start with a coarse grit
sanding paper and gradually change to finer and finer grit
sandpapers. A final sanding with a well-worn fine sandpaper will
produce a professional looking finish that in many cases will not need
hand sanding.
1. Disconnect the tool from the air source.
2. Prior to attaching the sanding disc, make sure the backing pad is
free of dirt, dust and foreign matter.
3. To attach the sanding disc, simply align the sanding disc on the
backing pad.
SANDING
WARNING! Make sure the air source is set to a maximum
of 90 PSI.
1. Connect the tool to its air source.
2. Turn the tool on by pressing down on the throttle lever (17) with
the palm of your hand. Wait until it has reached maximum speed
before placing it onto the work piece. Make sure the surface you
will be working on is free of any debris before placing the
running sanding disc onto the surface.
3. Move the tool slowly using a circular motion.
Visit www.princessauto.com for more information 9

8630790 6 in. Composite Orbital Air Palm Sander V1.0
4. Do not put additional pressure on the tool. This will slow down
the speed of the pad and reduce sanding efficiency, as well as
put an additional burden on the tool. If the tool requires more
force to accomplish the task, verify that the tool receives
sufficient, unobstructed airflow (CFM) and increase the pressure
(PSI) output of the regulator up to the maximum 90 PSI of the
tool. If the tool still does not have sufficient force at the
maximum pressure and sufficient airflow, then a larger tool may
be required.
CAUTION! Be careful not to apply the
sanding pad onto the workpiece when
running and tilted or the pad will sand
a groove into the workpiece, and the
sander will also try to move in the
direction of rotation. The may cause
loss of control of the tool.
See figure 1.
5. Always remove the tool from the
work piece before shutting the
tool off.
CARE & MAINTENANCE
Before making any adjustments or changing accessories, turn off the
tool and disconnect it from its power source.
1. Maintain the tool with care. A tool in good condition is efficient,
easier to control and will have fewer problems.
2. Keep the vent passage clear from dirt. Clean off the accumulated
dust and oil dirt periodically. Clean the tool after each use.
3. During normal operation, if anything happens, the power
supply should be cut off at once and the tool should be
checked and repaired.

V1.0 6 in. Composite Orbital Air Palm Sander 8630790
CLEANING
Keep the tool clean. Wipe the tool with a clean cloth and periodically
blow out all areas with compressed air. If compressed air is not
available, use a brush to remove dust from all areas. Do not use harsh
chemicals or solvents to clean the tool. These chemicals could
seriously damage the plastic housing.
Periodically, remove the backing pad (30), by sliding the pad wrench
(29) between the backing pad (30) and the pad cover (9). Engage
the nut on the shaft to lock it in place, and spin the backing pad (30)
off. Clean out the inner workings of the sander inside the housing (1.1)
with a vacuum or a brush. Replace the backing pad (30) securely.
MAINTENANCE SCHEDULE
Daily
Air Supply Maintenance: Every day, perform maintenance on
the air supply according to the component manufacturer’s
instructions. If a lubricator is used, the oil level needs to be
maintained and the moisture filter must be regularly drained.
Performing routine maintenance on the air supply will allow the tool
to operate more safely and will also reduce wear on the tool.
Weekly
Clean the muffler filter (if one is attached). Remove the
muffler cap (24), remove the filter and wash in warm water. Allow to
dry completely prior to replacement.
LUBRICATION
Only use air tool oil to lubricate the tool. Other lubricants may not
be suitable and could damage the tool or cause a malfunction
during use.
1. 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.
Visit www.princessauto.com for more information 13

8630790 6 in. Composite Orbital Air Palm Sander V1.0
2. 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.
3. 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.
4. Oiling your air tool regularly is important, but also is 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.
5. All air tools are packed in grease to prevent corrosion of internal
parts during shipping and storage. We recommend that you
clean this out to have optimum performance from your new air
tool. Use two drops of air tool oil to lubricate the tool and run the
tool under no load until exhaust is clear.
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.
NOTICE! 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.
STORAGE
When not in use for an extended period, apply a thin coat of lubricant
to the steel parts to avoid rust. Remove the lubricant before using the
14 For technical questions call 1-800-665-8685

V1.0 6 in. Composite Orbital Air Palm Sander 8630790
tool again. 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.
DISPOSAL
Recycle a tool damaged beyond repair at the appropriate facility.
