clothing or jewelry that could become caught by moving parts, causing injury.
Operate tool a safe distance from yourself and others in the work area.
4. Keep children away. Children must never be allowed in the work area. Do not

let them handle machines, tools, hoses or extension cords.
5. Store idle equipment. When not in use, tools must be stored in a dry location to
inhibit rust. Always lock up tools and keep out of reach of children and other
untrained persons. Switch off all unused electrical tools when stored. Tools are
dangerous in the hands of untrained users.
6. Always wear approved eye protection when using tools. If raising dust, wear a
suitable mask.
7. Work Safe. When wearing gloves to operate the tool, make sure that the gloves
do not interfere with operating the Trigger. Test your gloves with the Trigger
before attaching the unit to an air source. Keep your finger av/ay from the
Trigger until you are ready to work. Never start the tool unless you have a firm
grip with both hands and you are positioned at your work piece or area. Before
using the tool, know what is directly underneath the work area or work piece.
The tool can quickly penetrate material. If working directly on the ground, make
sure you are not directly above shallow cables, lines, or pipes. Keep your limbs
and body clear of the tool. If an accessory or attachment breaks off, the tool
tends lo surge forward suddenly. Operate tool a safe distance from yourself and
others in the work area. Make sure the immediate area is clear of other people
or animals. Spectators must stay at a safe distance. Never point the tool or the
air hose (not included) at anyone. Keep proper footing and balance at all times.
Do not reach over or across running machines, hoses, etc.
8. Do nol operate any tool if under the influence of alcohol or drugs. Read warning
labels on prescriptions to determine if your judgment or reflexes are impaired
while taking drugs. If there is any doubt, do not operate any tool.
9. Be sure air is in OFF position when connecting tool to air supply.
10. Use only those accessories that are designed tor use with tools. For example,
with impact wrenches do not use ordinary sockets. Use impact sockets for all
air tools.
11. Be sure to disconnect tool from air supply before changing accessories,
performing service on tool and when not in use.
12. Follow air source manufacturers' directions for connection of regulators, filters,
and other accessories to air source. Do not install quick couplers directly on
tool as they put unnecessary strain on the air inlet threads possibly causing
them to wear out prematurely, instead, install them on a short length of air
hose attached to the tool.
13. Check for damaged parts. Before using any tool, any part that appears
damaged should be carefully checked to determine that it will operate properly
and perform its intended function. Check for alignment and binding of moving
parts; any broken parts or mounting fixtures; and any other condition that may
affect proper operation. Any part that is damaged should be properly repaired
or replaced by a qualified technician.
14. Maintenance. For your safety, maintenance should be performed regularly by
a qualified technician using original NEILSEN® replacement parts.
Failure to do so can lead to accidents for the operator. Use of any other parts
will void the warranty. Only use accessories intended for use with this tool.
Approved accessories are available from Performance Tool®. Use only

accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool may become hazardous when
used on another tool.
WARNING: Repetitive motions or exposure to vibration may be harmful to your
hands and arms.
WARNING: This product and its packaging contain a chemical known to the State
of California to cause cancer, birth defects, or other reproductive harm.
WARNING: The warnings, cautions, and instructions discussed in this instruction
manual cannot cover all possible conditions and situations that may occur. It must
be understood by the operator that common sense and caution are factors which
cannot be built into this product, but must be supplied by the operator. Read and
understand all of the instructions provided in the instruction manual of this
product, as well as, any other tool (s) used with this product.
ASSEMBLY/INSTALLATION
1. You will need to prepare the 1/4" Quick-disconnect Coupler Plug to connect to
the air inlet on the sander. Wrap the Coupler Plug with pipe thread seal tape
before threading it into the Air Inlet. Connect the a Quick-Disconnect coupler on
a 3/8" ID Air Source Hose to the tool.
Note: If you are not using an automatic oiler system, before operation, add a few
drops of Pneumatic Tool Oil to the airline connection. Add a few drops more after
each hour of continual use.
2. Set the air pressure on your compressor to 90 PSI. Do not exceed the
recommended air pressure of 90 PSI.
3.Check the air connection for leaks. Once you are satisfied there are no leaks,
turn off the air compressor and disconnect the tool.
AIR SUPPLY
WARNING:
TO PREVENT SERIOUS INJURY FROM EXPLOSION:
Use only clean, dry, regulated, compressed air to power this tool. Do
not useoxygen, carbon dioxide, combustible gases, or any other
bottled gas as a power source for this tool.
1. Incorporate a filter, regulator with pressure gauge, in-line shutoff valve, and
quick coupler for best service, as shown in Figure A and Figure B .
An in-line shutoff ball valve is an important safety device because it
controls the air supply even if the air hose is ruptured. The shutoff valve
should be a ball valve because it can be closed quickly.

Note: If an automatic oiler system is not used, add a few drops of Pneumatic Tool
Oil to the airline connection before operation. Add a few more drops after each
hour of continual use.
2. Attach an air hose to the compressor’s air outlet. Connect the air hose to the air
inlet of the tool. Other components, such as a coupler plug and quick coupler,
will make operation more efficient, but are not required.
TO PREVENT SERIOUS INJURY
FROM ACCIDENTAL OPERATION: Do not install a female quick coupler
on the tool. Such a coupler contains an air valve that will allow the air tool to
retain pressure and operate accidentally after the air supply is disconnected.
Note: Air flow, and therefore tool performance, can be hindered by undersized air
supply components.
3. Turn the tool’s throttle or switch to the off position; refer to Operation section for
description of controls.
4. Close the in-line shutoff valve between the compressor and the tool.
5. Turn on the air compressor according to the manufacturer’s directions and
allow it to build up pressure until it cycles off.
6. Adjust the air compressor’s output regulator so that the air output is enough to
properly power the tool, but the output will not exceed the tool’s maximum air
pressure at any time. Adjust the pressure gradually, while checking the air
output gauge to set the right pressure range.
7. Inspect the air connections for leaks. Repair any leaks found.
8. If the tool will not be used at this time, turn off and detach the air supply and
safely discharge any residual air pressure to prevent accidental operation.
Note: Residual air pressure should not be present after the tool is disconnected
from the air supply. However, it is a good safety measure to attempt to discharge
the tool in a safe fashion after disconnecting to ensure that the tool is
disconnected and unpowered.

INSTALLING THE SANDING PAD
1. Disconnect the air hose from the tool.
2. Select the appropriate Sanding Pad (not included), and press it onto the
Backing Pad. Firmly press the Sanding Pad onto the Backing Pad, making
certain it is securely in place. Failure to properly secure the Sanding Pad may
cause the Sanding Pad to come loose, possibly causing personal injury or
property damage.
INSTALLING THE BACKING PAD
1. Disconnect tool from air supply.
2. Slide Wrench under Cover and onto the Arbor. Holding the wrench firmly, rotate
Arbor counterclockwise to remove.
3. To replace the Backing Pad, place wrench onto Arbor and hold firmly.
4. Place Backing Pad onto Arbor and turn clockwise to attach. Hand tighten firmly.
OPERATION
1. Turn the air compressor (not included) on and allow the air tank to come up to
pressure. Set the compressor output regulator to no more than 90 PSI.
2. Attach the air supply hose (not included) to the tool.
3. Grip the base of the tool in one hand. The Trigger will be under your palm.
Squeeze the tool to depress the Trigger and the tool will operate.
4. Place the tool on the work surface to begin sanding.
5. To stop sanding, lift the tool from the work surface, and relax your grip to allow
the Trigger to lift into the OFF position.
6. When you finish working, disconnect the air pressure hose from the tool and
turn off the air compressor.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities, contain chemicals known to the State of California to
cause cancer, birth defects or other reproductive harm. Some examples of these
chemicals are:
- Lead from lead-based paints
- Crystalline silica from bricks and cement or other masonry products
- Arsenic and chromium from chemically treated lumber
Your risk from these exposures varies, depending on how often you do this type of
work. To reduce your exposure to these chemicals: work in a well ventilated area, and
work with approved safety equipment, such as those dust masks that are specially
designed to filter out microscopic particles.
INSPECTION, MAINTENANCE & CLEANING
1. Make sure your Palm Grip Sander Is disconnected from the air hose before
attempting any maintenance.
2. Wipe the Palm Grip Sander down with a lint free cloth after each use.
3. If you do not use an inline oiler/filter system, lubricate the tool daily by holding it so
that the Valve is facing up.
4. Squeeze the Trigger, and place one or two drops of oil into the Valve, allowing oil to
circulate in the motor.
5. Store in a safe and dry location out of the reach of children.
LUBRICATION & MAINTENANCE
Oil tool before each use. 4 to 5 drops of a good grade Air Tool Oil placed in the air
inlet is sufficient. Use proper air pressure and CFM rating listed for this tool.
Drain water from hoses and compressor tank. Water in the air supply line will
cause gumming and loss of power. Clean the air filter on the supply line and flush
the tool with gum solvent or a 50/50 mix of air tool oil and kerosene. It may be
necessary to disassemble the tool to properly clean and re-lubricate.

TROUBLESHOOTING
INSUFFICIENT POWER:
Probable Cause Solution
Dirty or clogged air passages....... Flush and lubricate tool, drain air tank and supply line
Insufficient air supply..................... Increase line pressure, Make sure compressor
matches tool's air pressure and consumption needs
Air leakage..................................... Use PTFE tape at all fittings and joints. Check tool for worn
or damaged O-rings & seals.
Worn/damaged wear & tear parts.. Replace as necessary.
Tool matching................................ Be sure you are using a tool suited for the torque
requirements of the job at hand.
