ASSEMBLY / INSTALLATION
1. You will need to prepare the 1/4 in. Quick-disconnect Coupler Plug to connect to the air inlet on the
multifunction air tool. 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 in. 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.
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 ft. 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.
AIR SOURCE
INSTALLING ACCESORIES
1. While the air hose is disconnected from the tool, unthread the Cap Screw using the 3
mm Hex Wrench (included). Remove the Cap Screw, Lock Washer and Retainer.
2. Install the desired accessory in the correct angle for your application by aligning the
holes in the accessory over the 6 pins on the Output Shaft.
3. Replace the Retainer, Lock Washer and Cap Screw while holding the blade then tighten
securely using the Hex Wrench.
NOTE: For sanding, first attach the Sanding Pad to the tool, then align a sheet of sand
paper over the pad and press into place.
CHANGING ACCESSORIES
1.
Remove the Cap Screw, Lock Washer and Retainer using the included 3 mm Hex Wrench.
2. The accessories can be mounted in 7 different forward positions at 30° increments.
Mount the blades facing forward. Replace Cap Screw, Lock Washer and Retainer.
CAUTION: The Blades are sharp. Use care when handling the Blades.
INSTALLING/CHANGING AN ACCESSORY
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 to 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 not 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 for 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 PERFORMANCE TOOLS® 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: Some dust created by power sanding contains chemicals known to the State
of California to cause cancer, birth defects or other reproductive harm. Example of this type
of chemical are:
-lead from lead based paints,
-Crystalline Silica from bricks and cement or other masonry,
-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: work in a well ventilated area and work with approved safety
equipment, such as dusk masks that are specially designed to filter out microscopic particles.
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.
IMPORTANT SAFETY INFORMATION

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.
TROUBLESHOOTING
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.

YesNo
1. Make sure the tool is disconnected from the air hose before attempting any maintenance.
2. Wipe the tool down with a lint free cloth after each use.
3. If you do not use an inline oiler/filter system, lubricate the tool daily with a few drops of
air tool oil by holding it so that the valve is facing up. Squeeze the trigger lever, and place
one or two drops of oil into the valve, allowing oil to circulate in the motor.
4. If you do use an inline oiler/filter system the lubricator’s 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.
DAILY
Air supply maintenance: Every day, perform maintenance on the air supply according to
the component manufacturer's instructions.
QUARTERLY (every 3 months)
Tool disassembly, cleaning, and inspection:
a.
Have the internal mechanism cleaned, inspected, and lubricated by a qualified technician.
b. Replace accessories when they become worn or damaged.
5. Store in a safe and dry location out of the reach of children.
INSPECTION, MAINTENANCE & CLEANING
1. Attach the air hose from the air source to the Air Inlet on the air tool.
2. While holding the air tool firmly in one hand and the other safely out of the way of the
accessory, turn the air compressor (not included) on and allow the air tank to build up to
pressure. Set the compressor output regulator to no more than 90 PSI.
3. Grip the body of the tool in one hand. To begin use, push the Safety Lever forward while
squeezing the Trigger Lever. A stable two handed grip on this tool is best.
4. Place the air tool on the work surface to begin sanding, cutting, or scraping. Adjust
pressure on the Trigger Lever to change the speed of the air tool.
5. Address the material with a smooth steady stroke of the air tool.
NOTE: Do not force the air tool, let the air tool do the work.
6. If the air 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 air pressure rating for this air tool, 90 PSI.
7.
To stop sanding, lift the air tool from the work surface and then release the Trigger Lever.
8. When you finish working, disconnect the air pressure hose from the air tool and turn off
the air compressor.
CAUTION: To prevent tool and accessory failure, resulting in injury:
9. Do not exceed the tool’s maximum air pressure rating of 90 psi. If the tool still does not
have sufficient force at maximum pressure and sufficient airflow, then a larger tool may
be required.
10. To prevent accidents, turn off the tool by releasing the Trigger Lever, detaching the air
supply, and safely discharging any residual air pressure in the tool after use. Clean
external surfaces of the tool with a clean, dry cloth. Store the tool indoors out of
children’s reach.
