IMPORTANT SAFETY INFORMATION
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. Keep work area clean. Cluttered areas invite injuries.
2. 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 tools in the presence of ammable gases or liquids. Do not bring combustible
materials near the tools.
3. Keep children away. Children must never be allowed in the work area. Do not let them
handle machines, tools, hoses or extension cords.
4. 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.
5. Always wear approved eye protection when using tools. If raising dust, wear a suitable
mask.
6. Work Safe. When wearing gloves to operate the Air Hammer, make sure that the
gloves do not interfere with operating the Trigger (11). Test your gloves with the Trig-
ger (11) before attaching the unit to an air source. Keep your nger away from the
Trigger (11) until you are ready to work. Never start the tool unless you have a rm

grip with both hands and you are positioned at your workpiece or area. Before using
the Air Hammer, know what is directly underneath the work area or workpiece. The Air
Hammer can quickly penetrate material. If working directly on the ground, make sure
you are not directly above shallow cables, lines, or pipes. Do not wear loose clothing
or jewelry that could become caught by moving parts, causing injury. Keep your limbs
and body clear of the tool. If a chisel or bit 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.
7. Do not operate any tool if under the inuence of alcohol or drugs. Read warning labels
on prescriptions to determine if your judgment or reexes are impaired while taking
drugs. If there is any doubt, do not operate any tool.
8. Be sure air is in OFF position when connecting tool to air supply.
9. 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.
10. Be sure to disconnect tool from air supply before changing accessories, performing
service on tool and when not in use.
11. Follow air source manufacturers' directions for connection of regulators, lters, 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 prema-
turely. Instead, install them on a short length of air hose attached to the tool.
12. 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 xtures; and any other condition that may affect proper operation. Any part
that is damaged should be properly repaired or replaced by a qualied technician.
13. Maintenance. For your safety, maintenance should be performed regularly by a quali-
ed 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: 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
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 specications 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 per-
formance and damage of the air tool. Drain the air tank and lters 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.
AIR SOURCE
OPERATION
WARNING: Always disconnect the tool from the air source before
examining or changing bits.
1. Select the appropriate chisel/bit. Unscrew the Retainer Spring (18)
and insert the shank of the chisel/bit. Screw the Retainer Spring (18)
back onto the Cylinder (17). Holding the Air Chisel rmly, pull the
chisel/bit hard to make sure it locked into place.
Note: Before connecting the air supply, make sure you are wearing safety
goggles and a full face mask, ear protection, and steel toe shoes.
Warning: Any spectators in the immediate area will need eye and ear
protection. Beware of ying chips of wood, concrete, metal, or any other
material being chiseled.
2. Connect the air hose to the Air Inlet (8) and turn on the compressor
(not included).
3. Grip the Air Hammer with both hands rmly and put the chisel/bit tip
up against the workpiece you wish to chip.
4. Gently squeeze the Trigger (11) and move slowly along the work-
piece. Do not push down on the Air Hammer; let it do the work. If it
does not do the intended job to satisfaction, examine your bit to see if
it is worn or dull.
Warning!: Always disconnect from the air source before examining or
changing bits.
5. When you are nished, turn off the air supply and then hold the Air
Hammer in a safe direction and Squeeze the trigger to bleed off the
remaining air. Then, disconnect the air hose.
1.
You will need to prepare the 1/4" Quick-disconnect Coupler Plug to con-
nect to the air inlet on the Air Hammer. Wrap the Coupler Plug with pipe
thread seal tape before threading it into the Air Inlet (9). 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 satised there are no
leaks, turn off the air compressor and disconnect the tool.
ASSEMBLY / INSTALLATION
LUBRICATION & MAINTENANCE
Warning: Always disconnect from the air source before
attempting maintenance.
1. After each use, wipe the Air Hammer down with a lint free cloth.
2. Make sure there are no concrete chips, dirt, or debris in the Retainer
Spring (15).
3. Before storage, add a small quantity of high quality pneumatic oil in
the Air Inlet (8).
4. Examine your chisels/bits before using them. If a chisel is dull or
cracked do not use it. Replace worn or broken chisels with approved
replacement chisels from Performance Tool®.
Warning: 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 lter on the supply
line and ush 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. Wipe down the unit with a lint free cloth.
