SAFETY WARNINGS AND PRECAUTIONS
WARNING: When using tool, basic safety precautions should always be followed to reduce
the risk of personal injury and damage to equipment.
Read all instructions before using this tool!
Keep work area clean. Cluttered areas invite injuries.
Observe work area conditions. Do not use machines or power tools in damp or wet
locations. Don’t expose to rain. Keep work area well lighted. Do not use electrically
powered compressors in the presence of flammable gases or liquids.
Keep children away. Children must never be allowed in the work area. Do not let
them handle machines, tools, extension cords, or air hoses.
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.
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. There are certain applications for which this
tool was designed. It will do the job better and more safely at the rate for which it was
intended. Do not modify this tool and do not use this tool for a purpose for which it
was not intended.
Dress properly. Do not wear loose clothing or jewelry as they can be caught in mov-
ing parts. Protective, electrically non-conductive clothes and non-skid footwear are
recommended when working. Wear restrictive hair covering to contain long hair.

Use eye and ear protection. Always wear ANSI-approved impact safety
goggles and hearing protection. Wear a full face shield if you are producing
metal filings or wood chips. Wear an ANSI-approved dust mask or respira-
tor when working around metal, wood, and chemical dusts and mists.
Do not overreach. Keep proper footing and balance at all times. Do not reach over or
across running machines or air hoses.
Maintain tools with care. Keep tools clean for better and safer performance. Follow
instructions for lubricating and changing accessories. Inspect tool cords and air hoses
periodically and, if damaged, have them repaired by an authorized technician. The
handles must be kept clean, dry, and free from oil and grease at all times.
Disconnect air supply. Disconnect air hose when not in use.
Remove adjusting wrenches. Check that adjusting wrenches are removed from the
tool or machine work surface before operating the tool.
Avoid unintentional starting. Be sure the trigger is released when not in use and
before plugging in. Do not carry any tool with your finger on the trigger, whether it is
plugged in or not.
Stay alert. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.
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. Do
not use the tool if any switch does not turn On and Off properly.
Guard against electric shock. Prevent body contact with grounded surfaces such as
pipes, radiators, ranges, and refrigerator enclosures.
Replacement parts and accessories. When servicing, use only identical replacement
parts. Use of any other parts will void the warranty. Only use accessories intended for
use with this tool. Approved accessories are available from Harbor Freight Tools.
Do not operate tool if under the influence of alcohol or drugs. Read warning labels
if taking prescription medicine to determine if your judgement or reflexes are impaired
while taking drugs. If there is any doubt, do not operate the Sander.
Maintenance. For your safety, maintenance should be performed regularly by a quali-
fied technician.
Compressed air only. Use clean, dry regulated, compressed air at 90 PSI. Do not
exceed max. 90 PSI. Never use oxygen, carbon dioxide, combustible gases, or any
other bottled gas as a power source for this tool.

SETUP
Recommended Air Line Components
Palm Grip
Sander Air
Compressor
For best service you should incorporate an oiler, regulator, and inline filter, as shown in
the diagram above. Hoses, couplers, oilers, regulators, and filters are all available at Harbor
Freight Tools.
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.
You will need to prepare a 1/4” male air connector (not included) to be attached to the
Inlet Connector on the Palm Grip Sander. Wrap the 1/4” air connector with pipe thread
seal tape before threading it into the Inlet. Connect the 3/8” ID Air Hose to a quick con-
nect coupler (not included), and then to the Sander.
Set the air pressure on the regulator to 90 PSI. Do not exceed the recommended
air pressure of 90 PSI.
Check the air connection for leaks.

INSPECTION, MAINTENANCE AND CLEANING
Make sure your Palm Grip Sander is disconnected from the air hose before attempting
any maintenance.

the Valve (12) is facing up. Squeeze the Trigger (1), and place one or two drops of oil
into the Valve (12). Squeezing the Trigger (1) allows the oil to circulate in the motor.
Store in a safe and dry location out of the reach of children.
