IMPORTANT SAFETY INFORMATION
WARNING!
READ, UNDERSTAND AND FOLLOW ALL INSTRUCTIONS AND WARNINGS
BEFORE OPERATING THIS TOOL. FAILURE TO DO SO MAY RESULT IN
PERSONAL INJURY AND/OR PROPERTY DAMAGE AND WILL VOID WARRANTY.
1. Use only paper sanding disks with the proper adhesive. Read, under stand
and follow all adhesive manufacturers’ directions. DO NOT USE CLOTH
BACKED SANDING DISKS WITH THIS TOOL.
2. Make sure sanding pad RPM rating matches Free Speed rating of this tool.
3. Wear a dust mask while operating this tool. Read, follow and understand
manufacturers instructions on paint, primer, paint preps, glazing, body filler,
etc. for additional respirator and ventilating requirements.
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, Crystal-
line 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.
4. Always use approved eye and ear protection when using air powered tools.
If raising dust/debris, wear a suitable mask. Do not wear loose clothing or
jewelry.
5. Always operate tool a safe distance from yourself and others in the work
area. Keep footing and balance at all times.
6. Make sure work piece is secure to allow safe operation of the tool with both hands.
Do not hold the work piece in your hand, lap or against any part of your body.

IMPORTANT SAFETY INFORMATION
OPERATION
1. Regulate pad speed with air regulator knob.
2. Start the sander off the sanding surface. Set the sander on the surface gently and
evenly and start the work. Let the sander do the work. The weight of the sander
will provide efficient sanding. Applying pressure to the sander will only slow
the speed of the pad and reduce sanding efficiency. This will also overload the
motor and cause premature wear of the tool and void the warranty.
3. Work the sander back and forth in a wide, overlapping motion. Lift the sander off
the surface before releasing the trigger.
4. Start with a paper grit coarse enough to remove high spots and rough areas.
Continue using progressively finer grit to attain desired finish.
7. Make sure trigger is in the “off” position before connecting or disconnecting
the tool from air source. Disconnect tool from air source before changing
accessories, performing service and when not in use.
8. Follow air source manufacturer’s directions for connection of regulators,
filters and other accessories to air source. Do not install quick couplers
directly at tool air inlet. This causes inlet failure due to excess weight and
vibration. Use a whip hose between tool and quick couplers.
9. DO NOT OVERLOAD! Do not force tool. Match tool capacity to work load
requirement. Use tool within its rated capacity and only for its designated
purpose. Overloading air tools will cause premature wear and/or permanent
damage of internal and external drive parts and will void warranty.
10. Inspect hoses and fittings for wear and damage prior to using tool. Do not
carry or drag tool by the air hose. Keep air hose free from obstruction, twist-
ing and binding.
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.

AIR SOURCE
Clean air of correct air pressure is recommended for the power supply for this
tool. A maximum of 90 PSI at the tool is recommended for most air tools of this
class. Check specifications section for recommended pressure. (Depending on
length of air hose and other circumstances, air pressure at compressor may
need to be increased to 100 PSI to ensure 90 PSI at the tool.)
Water in the air hose and compressor tank contributes to reduced performance
and damage of the air tool. Drain the air tank and filters before each use and as
necessary to keep the air supply dry.
Hose length over 25’ causes loss in line pressure. Increase hose I.D. or increase
compressor pressure to compensate for the pressure loss. Use an in-line pressure
regulator with gauge if air inlet pressure is critical.
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.

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 lubing requirements of the
job at hand.
