Some dust created by power sanding contains chemicals known to the State of California to cause cancer, birth defects or other re-
productive harm. An example of this type of chemical is 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 lter out microscopic particles.

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.

IMPORTANT SAFETY INFORMATION
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 flammable gases or liquids. Do not bring combustible
materials near the tools.
3. As with any tool, use common sense when operating. Do not wear loose 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 away 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 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.

DAMAGE AND WILL VOID WARRANTY.
IMPORTANT SAFETY INFORMATION
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.

1. Use of a center punch to mark the starting point of a hole is recommended when drilling
metals with this tool. Place drill against work before starting motor. Do not apply too much
pressure to the drill as this can cause the bit to overheat and break. When the hole is drilled,
do not stop the drill until it is withdrawn from work.
2. If the drill should bind and stop inside the work, release the trigger immediately and
determine the cause. If removal of bit from the drill is necessary, disconnect the drill from the
air source before removing. Do not attempt to free the bit by forcing it with the drill.
3. A forward and reverse lever permits the tool to run in a forward (clockwise) rotation or in
reverse (Counter-clockwise) rotation. Do not attempt to change direction while tool is running.
OPERATION
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.
AIR SOURCE

Trigger
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.
