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 the tool as explained in this manual. If
abnormal vibrations occur, stop using this tool immediately.
USE AND CARE OF THE TOOL
1. Use the correct tool for the job. This tool was designed for a specific
function. Do not modify or alter this tool or use it for an
unintended purpose.
2. Do not carry the tool with fingers near or on the trigger/switch.

8572232 6 in. Random Orbit Palm Sander V4.0
3. Avoid unintentional starts. Be sure that the regulator/throttle switch is
in the neutral or OFF position when not in use and before connecting
it to any air source.
4. 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.
5. Conduct regular maintenance according to the schedule found in the
Maintenance section.
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. Maintain the tool with care
(see Maintenance).
7. When not in use for an extended period, apply a thin coat of lubricant
to the steel parts to avoid rust.
INSTALLING AIR QUICK COUPLER
Prepare a standard 1/4 in. NPT male air connector (sold separately) for
use with your tool.
1. Wrap the external threads of the male connector with sealant tape.
a. Wrap tape in a clockwise direction so it will not unravel.
b. Do not tape all the threads. Leave several leading threads
unwrapped for easier alignment.
2. Screw the connector into the tool's air inlet and tighten with a wrench
until snug.
3. Run compressor at a low volume and check the connection for air
leaks. Do not use the tool until all air leaks are repaired or the faulty

UNPACKING
1. Carefully remove the tool from the package.
a. Retain the packing material until you have carefully inspected and
satisfactorily installed or operated the tool.
2. Inspect the parts carefully to make sure the tool was 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.
OPERATION
ATTACHING 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. The tool uses
sanding discs which
are fastened by a nut
to the backing pad
on the mandrel.
3. Prior to attaching the sanding disc, make sure the backing pad is free
of dirt, dust and foreign matter.
Visit www.princessauto.com for more information

8572232 6 in. Random Orbit Palm Sander
4. To attach the sanding disc, simply align the sanding disc on the
backing pad. Screw on the nut to fix the sanding disc in place.
OPERATION
1. Connect the tool to its air source.
V4.0
2. Turn the tool on. 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.
4. Do not put additional pressure on the die grinder. This will slow down
the speed of the pad and reduce sanding efficiency, as well as put an
additional burden on the tool.
5. Always remove the tool from the work piece before shutting the
tool off.
SPEED ADJUSTMENT
The rotation speed adjustment can be made by
opening/closing the valve near the air inlet.
MAINTENANCE
Before making any adjustments or changing
accessories, turn off the tool and disconnect it from its power source.
1. Keep the vent passage clear from dirt. Clean off the accumulated dust
and oil dirt periodically. Clean the tool after each use.
2. During normal operation, if anything happens, the power supply
should be cut off at once and the tool should be checked
and repaired.

V4.0 6 in. Random Orbit Palm Sander 8572232
3. Check for damaged parts. Before using any tool, any part that
appears to be damaged should be carefully checked to determine that
it would operate properly and perform its intended functions. Check
for alignment and binding of moving parts, for broken parts or
mounting fixtures, or for any other condition that may affect proper
operation. Any part that is damaged should be repaired or replaced
by a qualified technician.
4. When servicing, use only identical replacement parts. Only use
accessories intended for use with this tool. Replace damaged
parts immediately.
5. 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.
6. Regularly inspect all mounting screws to ensure tightness. Should
any screws become loose, tighten immediately.
7. If repairs are required, bring your tool to an authorized service centre.
WARNING! Only qualified service personnel should repair the tool. An
improperly repaired tool may present a hazard to the user
and/or others.
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 11

8572232 6 in. Random Orbit Palm Sander V4.0
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 I or loss of
power. Use only recommended lubricants, specially made for
pneumatic applications. Substitutes may harm the rubber
compounds in the tool's 0-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.
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 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
If your tool has become damaged beyond repair, do not throw it out.
Take it to the appropriate recycling facility.
